NAME
hgrc - configuration files for Mercurial
DESCRIPTION
The Mercurial system uses a set of configuration files to control aspects of its behavior.
TROUBLESHOOTING
If you're having problems with your configuration, hg config --debug can help you
understand what is introducing a setting into your environment.
See hg help config.syntax and hg help config.files for information about how and where to
override things.
STRUCTURE
The configuration files use a simple ini-file format. A configuration file consists of
sections, led by a [section] header and followed by name = value entries:
[ui]
username = Firstname Lastname <firstname.lastname@example.net>
verbose = True
The above entries will be referred to as ui.username and ui.verbose, respectively. See hg
help config.syntax.
FILES
Mercurial reads configuration data from several files, if they exist. These files do not
exist by default and you will have to create the appropriate configuration files yourself:
Local configuration is put into the per-repository <repo>/.hg/hgrc file.
Global configuration like the username setting is typically put into:
• %USERPROFILE%\mercurial.ini (on Windows)
• $HOME/.hgrc (on Unix, Plan9)
The names of these files depend on the system on which Mercurial is installed. *.rc files
from a single directory are read in alphabetical order, later ones overriding earlier
ones. Where multiple paths are given below, settings from earlier paths override later
ones.
On Unix, the following files are consulted:
• <repo>/.hg/hgrc (per-repository)
• $HOME/.hgrc (per-user)
• ${XDG_CONFIG_HOME:-$HOME/.config}/hg/hgrc (per-user)
• <install-root>/etc/mercurial/hgrc (per-installation)
• <install-root>/etc/mercurial/hgrc.d/*.rc (per-installation)
• /etc/mercurial/hgrc (per-system)
• /etc/mercurial/hgrc.d/*.rc (per-system)
• <internal>/*.rc (defaults)
On Windows, the following files are consulted:
• <repo>/.hg/hgrc (per-repository)
• %USERPROFILE%\.hgrc (per-user)
• %USERPROFILE%\Mercurial.ini (per-user)
• %HOME%\.hgrc (per-user)
• %HOME%\Mercurial.ini (per-user)
• HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial (per-system)
• <install-dir>\hgrc.d\*.rc (per-installation)
• <install-dir>\Mercurial.ini (per-installation)
• %PROGRAMDATA%\Mercurial\hgrc (per-system)
• %PROGRAMDATA%\Mercurial\Mercurial.ini (per-system)
• %PROGRAMDATA%\Mercurial\hgrc.d\*.rc (per-system)
• <internal>/*.rc (defaults)
Note The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mercurial is used when
running 32-bit Python on 64-bit Windows.
On Plan9, the following files are consulted:
• <repo>/.hg/hgrc (per-repository)
• $home/lib/hgrc (per-user)
• <install-root>/lib/mercurial/hgrc (per-installation)
• <install-root>/lib/mercurial/hgrc.d/*.rc (per-installation)
• /lib/mercurial/hgrc (per-system)
• /lib/mercurial/hgrc.d/*.rc (per-system)
• <internal>/*.rc (defaults)
Per-repository configuration options only apply in a particular repository. This file is
not version-controlled, and will not get transferred during a "clone" operation. Options
in this file override options in all other configuration files.
On Plan 9 and Unix, most of this file will be ignored if it doesn't belong to a trusted
user or to a trusted group. See hg help config.trusted for more details.
Per-user configuration file(s) are for the user running Mercurial. Options in these files
apply to all Mercurial commands executed by this user in any directory. Options in these
files override per-system and per-installation options.
Per-installation configuration files are searched for in the directory where Mercurial is
installed. <install-root> is the parent directory of the hg executable (or symlink) being
run.
For example, if installed in /shared/tools/bin/hg, Mercurial will look in
/shared/tools/etc/mercurial/hgrc. Options in these files apply to all Mercurial commands
executed by any user in any directory.
Per-installation configuration files are for the system on which Mercurial is running.
Options in these files apply to all Mercurial commands executed by any user in any
directory. Registry keys contain PATH-like strings, every part of which must reference a
Mercurial.ini file or be a directory where *.rc files will be read. Mercurial checks each
of these locations in the specified order until one or more configuration files are
detected.
Per-system configuration files are for the system on which Mercurial is running. Options
in these files apply to all Mercurial commands executed by any user in any directory.
Options in these files override per-installation options.
Mercurial comes with some default configuration. The default configuration files are
installed with Mercurial and will be overwritten on upgrades. Default configuration files
should never be edited by users or administrators but can be overridden in other
configuration files. So far the directory only contains merge tool configuration but
packagers can also put other default configuration there.
SYNTAX
A configuration file consists of sections, led by a [section] header and followed by name
= value entries (sometimes called configuration keys):
[spam]
eggs=ham
green=
eggs
Each line contains one entry. If the lines that follow are indented, they are treated as
continuations of that entry. Leading whitespace is removed from values. Empty lines are
skipped. Lines beginning with # or ; are ignored and may be used to provide comments.
Configuration keys can be set multiple times, in which case Mercurial will use the value
that was configured last. As an example:
[spam]
eggs=large
ham=serrano
eggs=small
This would set the configuration key named eggs to small.
It is also possible to define a section multiple times. A section can be redefined on the
same and/or on different configuration files. For example:
[foo]
eggs=large
ham=serrano
eggs=small
[bar]
eggs=ham
green=
eggs
[foo]
ham=prosciutto
eggs=medium
bread=toasted
This would set the eggs, ham, and bread configuration keys of the foo section to medium,
prosciutto, and toasted, respectively. As you can see there only thing that matters is the
last value that was set for each of the configuration keys.
If a configuration key is set multiple times in different configuration files the final
value will depend on the order in which the different configuration files are read, with
settings from earlier paths overriding later ones as described on the Files section above.
A line of the form %include file will include file into the current configuration file.
The inclusion is recursive, which means that included files can include other files.
Filenames are relative to the configuration file in which the %include directive is found.
Environment variables and ~user constructs are expanded in file. This lets you do
something like:
%include ~/.hgrc.d/$HOST.rc
to include a different configuration file on each computer you use.
A line with %unset name will remove name from the current section, if it has been set
previously.
The values are either free-form text strings, lists of text strings, or Boolean values.
Boolean values can be set to true using any of "1", "yes", "true", or "on" and to false
using "0", "no", "false", or "off" (all case insensitive).
List values are separated by whitespace or comma, except when values are placed in double
quotation marks:
allow_read = "John Doe, PhD", brian, betty
Quotation marks can be escaped by prefixing them with a backslash. Only quotation marks at
the beginning of a word is counted as a quotation (e.g., foo"bar baz is the list of
foo"bar and baz).
SECTIONS
This section describes the different sections that may appear in a Mercurial configuration
file, the purpose of each section, its possible keys, and their possible values.
alias
Defines command aliases.
Aliases allow you to define your own commands in terms of other commands (or aliases),
optionally including arguments. Positional arguments in the form of $1, $2, etc. in the
alias definition are expanded by Mercurial before execution. Positional arguments not
already used by $N in the definition are put at the end of the command to be executed.
Alias definitions consist of lines of the form:
<alias> = <command> [<argument>]...
For example, this definition:
latest = log --limit 5
creates a new command latest that shows only the five most recent changesets. You can
define subsequent aliases using earlier ones:
stable5 = latest -b stable
Note It is possible to create aliases with the same names as existing commands, which
will then override the original definitions. This is almost always a bad idea!
An alias can start with an exclamation point (!) to make it a shell alias. A shell alias
is executed with the shell and will let you run arbitrary commands. As an example,
echo = !echo $@
will let you do hg echo foo to have foo printed in your terminal. A better example might
be:
purge = !$HG status --no-status --unknown -0 re: | xargs -0 rm -f
which will make hg purge delete all unknown files in the repository in the same manner as
the purge extension.
Positional arguments like $1, $2, etc. in the alias definition expand to the command
arguments. Unmatched arguments are removed. $0 expands to the alias name and $@ expands to
all arguments separated by a space. "$@" (with quotes) expands to all arguments quoted
individually and separated by a space. These expansions happen before the command is
passed to the shell.
Shell aliases are executed in an environment where $HG expands to the path of the
Mercurial that was used to execute the alias. This is useful when you want to call further
Mercurial commands in a shell alias, as was done above for the purge alias. In addition,
$HG_ARGS expands to the arguments given to Mercurial. In the hg echo foo call above,
$HG_ARGS would expand to echo foo.
Note Some global configuration options such as -R are processed before shell aliases and
will thus not be passed to aliases.
annotate
Settings used when displaying file annotations. All values are Booleans and default to
False. See hg help config.diff for related options for the diff command.
ignorews
Ignore white space when comparing lines.
ignorewseol
Ignore white space at the end of a line when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
auth
Authentication credentials and other authentication-like configuration for HTTP
connections. This section allows you to store usernames and passwords for use when logging
into HTTP servers. See hg help config.web if you want to configure who can login to your
HTTP server.
The following options apply to all hosts.
cookiefile
Path to a file containing HTTP cookie lines. Cookies matching a host will be sent
automatically.
The file format uses the Mozilla cookies.txt format, which defines cookies on their
own lines. Each line contains 7 fields delimited by the tab character (domain,
is_domain_cookie, path, is_secure, expires, name, value). For more info, do an
Internet search for "Netscape cookies.txt format."
Note: the cookies parser does not handle port numbers on domains. You will need to
remove ports from the domain for the cookie to be recognized. This could result in
a cookie being disclosed to an unwanted server.
The cookies file is read-only.
Other options in this section are grouped by name and have the following format:
<name>.<argument> = <value>
where <name> is used to group arguments into authentication entries. Example:
foo.prefix = hg.intevation.de/mercurial
foo.username = foo
foo.password = bar
foo.schemes = http https
bar.prefix = secure.example.org
bar.key = path/to/file.key
bar.cert = path/to/file.cert
bar.schemes = https
Supported arguments:
prefix
Either * or a URI prefix with or without the scheme part. The authentication entry
with the longest matching prefix is used (where * matches everything and counts as
a match of length 1). If the prefix doesn't include a scheme, the match is
performed against the URI with its scheme stripped as well, and the schemes
argument, q.v., is then subsequently consulted.
username
Optional. Username to authenticate with. If not given, and the remote site requires
basic or digest authentication, the user will be prompted for it. Environment
variables are expanded in the username letting you do foo.username = $USER. If the
URI includes a username, only [auth] entries with a matching username or without a
username will be considered.
password
Optional. Password to authenticate with. If not given, and the remote site requires
basic or digest authentication, the user will be prompted for it.
key
Optional. PEM encoded client certificate key file. Environment variables are
expanded in the filename.
cert
Optional. PEM encoded client certificate chain file. Environment variables are
expanded in the filename.
schemes
Optional. Space separated list of URI schemes to use this authentication entry
with. Only used if the prefix doesn't include a scheme. Supported schemes are http
and https. They will match static-http and static-https respectively, as well.
(default: https)
If no suitable authentication entry is found, the user is prompted for credentials as
usual if required by the remote.
color
Configure the Mercurial color mode. For details about how to define your custom effect and
style see hg help color.
mode
String: control the method used to output color. One of auto, ansi, win32, terminfo
or debug. In auto mode, Mercurial will use ANSI mode by default (or win32 mode
prior to Windows 10) if it detects a terminal. Any invalid value will disable
color.
pagermode
String: optional override of color.mode used with pager.
On some systems, terminfo mode may cause problems when using color with less -R as
a pager program. less with the -R option will only display ECMA-48 color codes, and
terminfo mode may sometimes emit codes that less doesn't understand. You can work
around this by either using ansi mode (or auto mode), or by using less -r (which
will pass through all terminal control codes, not just color control codes).
On some systems (such as MSYS in Windows), the terminal may support a different
color mode than the pager program.
commands
commit.post-status
Show status of files in the working directory after successful commit. (default:
False)
merge.require-rev
Require that the revision to merge the current commit with be specified on the
command line. If this is enabled and a revision is not specified, the command
aborts. (default: False)
push.require-revs
Require revisions to push be specified using one or more mechanisms such as
specifying them positionally on the command line, using -r, -b, and/or -B on the
command line, or using paths.<path>:pushrev in the configuration. If this is
enabled and revisions are not specified, the command aborts. (default: False)
resolve.confirm
Confirm before performing action if no filename is passed. (default: False)
resolve.explicit-re-merge
Require uses of hg resolve to specify which action it should perform, instead of
re-merging files by default. (default: False)
resolve.mark-check
Determines what level of checking hg resolve --mark will perform before marking
files as resolved. Valid values are none`, ``warn, and abort. warn will output a
warning listing the file(s) that still have conflict markers in them, but will
still mark everything resolved. abort will output the same warning but will not
mark things as resolved. If --all is passed and this is set to abort, only a
warning will be shown (an error will not be raised). (default: none)
status.relative
Make paths in hg status output relative to the current directory. (default: False)
status.terse
Default value for the --terse flag, which condenses status output. (default:
empty)
update.check
Determines what level of checking hg update will perform before moving to a
destination revision. Valid values are abort, none, linear, and noconflict. abort
always fails if the working directory has uncommitted changes. none performs no
checking, and may result in a merge with uncommitted changes. linear allows any
update as long as it follows a straight line in the revision history, and may
trigger a merge with uncommitted changes. noconflict will allow any update which
would not trigger a merge with uncommitted changes, if any are present. (default:
linear)
update.requiredest
Require that the user pass a destination when running hg update. For example, hg
update .:: will be allowed, but a plain hg update will be disallowed. (default:
False)
committemplate
changeset
String: configuration in this section is used as the template to customize the text
shown in the editor when committing.
In addition to pre-defined template keywords, commit log specific one below can be used
for customization:
extramsg
String: Extra message (typically 'Leave message empty to abort commit.'). This may
be changed by some commands or extensions.
For example, the template configuration below shows as same text as one shown by default:
[committemplate]
changeset = {desc}\n\n
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: {extramsg}
HG: --
HG: user: {author}\n{ifeq(p2rev, "-1", "",
"HG: branch merge\n")
}HG: branch '{branch}'\n{if(activebookmark,
"HG: bookmark '{activebookmark}'\n") }{subrepos %
"HG: subrepo {subrepo}\n" }{file_adds %
"HG: added {file}\n" }{file_mods %
"HG: changed {file}\n" }{file_dels %
"HG: removed {file}\n" }{if(files, "",
"HG: no files changed\n")}
diff()
String: show the diff (see hg help templates for detail)
Sometimes it is helpful to show the diff of the changeset in the editor without having to
prefix 'HG: ' to each line so that highlighting works correctly. For this, Mercurial
provides a special string which will ignore everything below it:
HG: ------------------------ >8 ------------------------
For example, the template configuration below will show the diff below the extra message:
[committemplate]
changeset = {desc}\n\n
HG: Enter commit message. Lines beginning with 'HG:' are removed.
HG: {extramsg}
HG: ------------------------ >8 ------------------------
HG: Do not touch the line above.
HG: Everything below will be removed.
{diff()}
Note For some problematic encodings (see hg help win32mbcs for detail), this
customization should be configured carefully, to avoid showing broken characters.
For example, if a multibyte character ending with backslash (0x5c) is followed by
the ASCII character 'n' in the customized template, the sequence of backslash and
'n' is treated as line-feed unexpectedly (and the multibyte character is broken,
too).
Customized template is used for commands below (--edit may be required):
• hg backout
• hg commit
• hg fetch (for merge commit only)
• hg graft
• hg histedit
• hg import
• hg qfold, hg qnew and hg qrefresh
• hg rebase
• hg shelve
• hg sign
• hg tag
• hg transplant
Configuring items below instead of changeset allows showing customized message only for
specific actions, or showing different messages for each action.
• changeset.backout for hg backout
• changeset.commit.amend.merge for hg commit --amend on merges
• changeset.commit.amend.normal for hg commit --amend on other
• changeset.commit.normal.merge for hg commit on merges
• changeset.commit.normal.normal for hg commit on other
• changeset.fetch for hg fetch (impling merge commit)
• changeset.gpg.sign for hg sign
• changeset.graft for hg graft
• changeset.histedit.edit for edit of hg histedit
• changeset.histedit.fold for fold of hg histedit
• changeset.histedit.mess for mess of hg histedit
• changeset.histedit.pick for pick of hg histedit
• changeset.import.bypass for hg import --bypass
• changeset.import.normal.merge for hg import on merges
• changeset.import.normal.normal for hg import on other
• changeset.mq.qnew for hg qnew
• changeset.mq.qfold for hg qfold
• changeset.mq.qrefresh for hg qrefresh
• changeset.rebase.collapse for hg rebase --collapse
• changeset.rebase.merge for hg rebase on merges
• changeset.rebase.normal for hg rebase on other
• changeset.shelve.shelve for hg shelve
• changeset.tag.add for hg tag without --remove
• changeset.tag.remove for hg tag --remove
• changeset.transplant.merge for hg transplant on merges
• changeset.transplant.normal for hg transplant on other
These dot-separated lists of names are treated as hierarchical ones. For example,
changeset.tag.remove customizes the commit message only for hg tag --remove, but
changeset.tag customizes the commit message for hg tag regardless of --remove option.
When the external editor is invoked for a commit, the corresponding dot-separated list of
names without the changeset. prefix (e.g. commit.normal.normal) is in the HGEDITFORM
environment variable.
In this section, items other than changeset can be referred from others. For example, the
configuration to list committed files up below can be referred as {listupfiles}:
[committemplate]
listupfiles = {file_adds %
"HG: added {file}\n" }{file_mods %
"HG: changed {file}\n" }{file_dels %
"HG: removed {file}\n" }{if(files, "",
"HG: no files changed\n")}
decode/encode
Filters for transforming files on checkout/checkin. This would typically be used for
newline processing or other localization/canonicalization of files.
Filters consist of a filter pattern followed by a filter command. Filter patterns are
globs by default, rooted at the repository root. For example, to match any file ending in
.txt in the root directory only, use the pattern *.txt. To match any file ending in .c
anywhere in the repository, use the pattern **.c. For each file only the first matching
filter applies.
The filter command can start with a specifier, either pipe: or tempfile:. If no specifier
is given, pipe: is used by default.
A pipe: command must accept data on stdin and return the transformed data on stdout.
Pipe example:
[encode]
# uncompress gzip files on checkin to improve delta compression
# note: not necessarily a good idea, just an example
*.gz = pipe: gunzip
[decode]
# recompress gzip files when writing them to the working dir (we
# can safely omit "pipe:", because it's the default)
*.gz = gzip
A tempfile: command is a template. The string INFILE is replaced with the name of a
temporary file that contains the data to be filtered by the command. The string OUTFILE is
replaced with the name of an empty temporary file, where the filtered data must be written
by the command.
Note The tempfile mechanism is recommended for Windows systems, where the standard shell
I/O redirection operators often have strange effects and may corrupt the contents
of your files.
This filter mechanism is used internally by the eol extension to translate line ending
characters between Windows (CRLF) and Unix (LF) format. We suggest you use the eol
extension for convenience.
defaults
(defaults are deprecated. Don't use them. Use aliases instead.)
Use the [defaults] section to define command defaults, i.e. the default options/arguments
to pass to the specified commands.
The following example makes hg log run in verbose mode, and hg status show only the
modified files, by default:
[defaults]
log = -v
status = -m
The actual commands, instead of their aliases, must be used when defining command
defaults. The command defaults will also be applied to the aliases of the commands
defined.
diff
Settings used when displaying diffs. Everything except for unified is a Boolean and
defaults to False. See hg help config.annotate for related options for the annotate
command.
git
Use git extended diff format.
nobinary
Omit git binary patches.
nodates
Don't include dates in diff headers.
noprefix
Omit 'a/' and 'b/' prefixes from filenames. Ignored in plain mode.
showfunc
Show which function each change is in.
ignorews
Ignore white space when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
unified
Number of lines of context to show.
word-diff
Highlight changed words.
email
Settings for extensions that send email messages.
from
Optional. Email address to use in "From" header and SMTP envelope of outgoing
messages.
to
Optional. Comma-separated list of recipients' email addresses.
cc
Optional. Comma-separated list of carbon copy recipients' email addresses.
bcc
Optional. Comma-separated list of blind carbon copy recipients' email addresses.
method
Optional. Method to use to send email messages. If value is smtp (default), use
SMTP (see the [smtp] section for configuration). Otherwise, use as name of program
to run that acts like sendmail (takes -f option for sender, list of recipients on
command line, message on stdin). Normally, setting this to sendmail or
/usr/sbin/sendmail is enough to use sendmail to send messages.
charsets
Optional. Comma-separated list of character sets considered convenient for
recipients. Addresses, headers, and parts not containing patches of outgoing
messages will be encoded in the first character set to which conversion from local
encoding ($HGENCODING, ui.fallbackencoding) succeeds. If correct conversion fails,
the text in question is sent as is. (default: '')
Order of outgoing email character sets:
1. us-ascii: always first, regardless of settings
2. email.charsets: in order given by user
3. ui.fallbackencoding: if not in email.charsets
4. $HGENCODING: if not in email.charsets
5. utf-8: always last, regardless of settings
Email example:
[email]
from = Joseph User <joe.user@example.com>
method = /usr/sbin/sendmail
# charsets for western Europeans
# us-ascii, utf-8 omitted, as they are tried first and last
charsets = iso-8859-1, iso-8859-15, windows-1252
extensions
Mercurial has an extension mechanism for adding new features. To enable an extension,
create an entry for it in this section.
If you know that the extension is already in Python's search path, you can give the name
of the module, followed by =, with nothing after the =.
Otherwise, give a name that you choose, followed by =, followed by the path to the .py
file (including the file name extension) that defines the extension.
To explicitly disable an extension that is enabled in an hgrc of broader scope, prepend
its path with !, as in foo = !/ext/path or foo = ! when path is not supplied.
Example for ~/.hgrc:
[extensions]
# (the churn extension will get loaded from Mercurial's path)
churn =
# (this extension will get loaded from the file specified)
myfeature = ~/.hgext/myfeature.py
format
Configuration that controls the repository format. Newer format options are more powerful,
but incompatible with some older versions of Mercurial. Format options are considered at
repository initialization only. You need to make a new clone for config changes to be
taken into account.
For more details about repository format and version compatibility, see
https://www.mercurial-scm.org/wiki/MissingRequirement
usegeneraldelta
Enable or disable the "generaldelta" repository format which improves repository
compression by allowing "revlog" to store deltas against arbitrary revisions
instead of the previously stored one. This provides significant improvement for
repositories with branches.
Repositories with this on-disk format require Mercurial version 1.9.
Enabled by default.
dotencode
Enable or disable the "dotencode" repository format which enhances the "fncache"
repository format (which has to be enabled to use dotencode) to avoid issues with
filenames starting with "._" on Mac OS X and spaces on Windows.
Repositories with this on-disk format require Mercurial version 1.7.
Enabled by default.
usefncache
Enable or disable the "fncache" repository format which enhances the "store"
repository format (which has to be enabled to use fncache) to allow longer
filenames and avoids using Windows reserved names, e.g. "nul".
Repositories with this on-disk format require Mercurial version 1.1.
Enabled by default.
usestore
Enable or disable the "store" repository format which improves compatibility with
systems that fold case or otherwise mangle filenames. Disabling this option will
allow you to store longer filenames in some situations at the expense of
compatibility.
Repositories with this on-disk format require Mercurial version 0.9.4.
Enabled by default.
sparse-revlog
Enable or disable the sparse-revlog delta strategy. This format improves delta
re-use inside revlog. For very branchy repositories, it results in a smaller store.
For repositories with many revisions, it also helps performance (by using shortened
delta chains.)
Repositories with this on-disk format require Mercurial version 4.7
Enabled by default.
revlog-compression
Compression algorithm used by revlog. Supported values are zlib and zstd. The zlib
engine is the historical default of Mercurial. zstd is a newer format that is
usually a net win over zlib, operating faster at better compression rates. Use zstd
to reduce CPU usage.
On some systems, the Mercurial installation may lack zstd support.
Default is zlib.
bookmarks-in-store
Store bookmarks in .hg/store/. This means that bookmarks are shared when using hg
share regardless of the -B option.
Repositories with this on-disk format require Mercurial version 5.1.
Disabled by default.
graph
Web graph view configuration. This section let you change graph elements display
properties by branches, for instance to make the default branch stand out.
Each line has the following format:
<branch>.<argument> = <value>
where <branch> is the name of the branch being customized. Example:
[graph]
# 2px width
default.width = 2
# red color
default.color = FF0000
Supported arguments:
width
Set branch edges width in pixels.
color
Set branch edges color in hexadecimal RGB notation.
hooks
Commands or Python functions that get automatically executed by various actions such as
starting or finishing a commit. Multiple hooks can be run for the same action by appending
a suffix to the action. Overriding a site-wide hook can be done by changing its value or
setting it to an empty string. Hooks can be prioritized by adding a prefix of priority.
to the hook name on a new line and setting the priority. The default priority is 0.
Example .hg/hgrc:
[hooks]
# update working directory after adding changesets
changegroup.update = hg update
# do not use the site-wide hook
incoming =
incoming.email = /my/email/hook
incoming.autobuild = /my/build/hook
# force autobuild hook to run before other incoming hooks
priority.incoming.autobuild = 1
Most hooks are run with environment variables set that give useful additional information.
For each hook below, the environment variables it is passed are listed with names in the
form $HG_foo. The $HG_HOOKTYPE and $HG_HOOKNAME variables are set for all hooks. They
contain the type of hook which triggered the run and the full name of the hook in the
config, respectively. In the example above, this will be $HG_HOOKTYPE=incoming and
$HG_HOOKNAME=incoming.email.
Some basic Unix syntax can be enabled for portability, including $VAR and ${VAR} style
variables. A ~ followed by \ or / will be expanded to %USERPROFILE% to simulate a subset
of tilde expansion on Unix. To use a literal $ or ~, it must be escaped with a back slash
or inside of a strong quote. Strong quotes will be replaced by double quotes after
processing.
This feature is enabled by adding a prefix of tonative. to the hook name on a new line,
and setting it to True. For example:
[hooks]
incoming.autobuild = /my/build/hook
# enable translation to cmd.exe syntax for autobuild hook
tonative.incoming.autobuild = True
changegroup
Run after a changegroup has been added via push, pull or unbundle. The ID of the
first new changeset is in $HG_NODE and last is in $HG_NODE_LAST. The URL from
which changes came is in $HG_URL.
commit
Run after a changeset has been created in the local repository. The ID of the newly
created changeset is in $HG_NODE. Parent changeset IDs are in $HG_PARENT1 and
$HG_PARENT2.
incoming
Run after a changeset has been pulled, pushed, or unbundled into the local
repository. The ID of the newly arrived changeset is in $HG_NODE. The URL that was
source of the changes is in $HG_URL.
outgoing
Run after sending changes from the local repository to another. The ID of first
changeset sent is in $HG_NODE. The source of operation is in $HG_SOURCE. Also see
hg help config.hooks.preoutgoing.
post-<command>
Run after successful invocations of the associated command. The contents of the
command line are passed as $HG_ARGS and the result code in $HG_RESULT. Parsed
command line arguments are passed as $HG_PATS and $HG_OPTS. These contain string
representations of the python data internally passed to <command>. $HG_OPTS is a
dictionary of options (with unspecified options set to their defaults). $HG_PATS
is a list of arguments. Hook failure is ignored.
fail-<command>
Run after a failed invocation of an associated command. The contents of the command
line are passed as $HG_ARGS. Parsed command line arguments are passed as $HG_PATS
and $HG_OPTS. These contain string representations of the python data internally
passed to <command>. $HG_OPTS is a dictionary of options (with unspecified options
set to their defaults). $HG_PATS is a list of arguments. Hook failure is ignored.
pre-<command>
Run before executing the associated command. The contents of the command line are
passed as $HG_ARGS. Parsed command line arguments are passed as $HG_PATS and
$HG_OPTS. These contain string representations of the data internally passed to
<command>. $HG_OPTS is a dictionary of options (with unspecified options set to
their defaults). $HG_PATS is a list of arguments. If the hook returns failure, the
command doesn't execute and Mercurial returns the failure code.
prechangegroup
Run before a changegroup is added via push, pull or unbundle. Exit status 0 allows
the changegroup to proceed. A non-zero status will cause the push, pull or unbundle
to fail. The URL from which changes will come is in $HG_URL.
precommit
Run before starting a local commit. Exit status 0 allows the commit to proceed. A
non-zero status will cause the commit to fail. Parent changeset IDs are in
$HG_PARENT1 and $HG_PARENT2.
prelistkeys
Run before listing pushkeys (like bookmarks) in the repository. A non-zero status
will cause failure. The key namespace is in $HG_NAMESPACE.
preoutgoing
Run before collecting changes to send from the local repository to another. A
non-zero status will cause failure. This lets you prevent pull over HTTP or SSH. It
can also prevent propagating commits (via local pull, push (outbound) or bundle
commands), but not completely, since you can just copy files instead. The source of
operation is in $HG_SOURCE. If "serve", the operation is happening on behalf of a
remote SSH or HTTP repository. If "push", "pull" or "bundle", the operation is
happening on behalf of a repository on same system.
prepushkey
Run before a pushkey (like a bookmark) is added to the repository. A non-zero
status will cause the key to be rejected. The key namespace is in $HG_NAMESPACE,
the key is in $HG_KEY, the old value (if any) is in $HG_OLD, and the new value is
in $HG_NEW.
pretag
Run before creating a tag. Exit status 0 allows the tag to be created. A non-zero
status will cause the tag to fail. The ID of the changeset to tag is in $HG_NODE.
The name of tag is in $HG_TAG. The tag is local if $HG_LOCAL=1, or in the
repository if $HG_LOCAL=0.
pretxnopen
Run before any new repository transaction is open. The reason for the transaction
will be in $HG_TXNNAME, and a unique identifier for the transaction will be in
HG_TXNID. A non-zero status will prevent the transaction from being opened.
pretxnclose
Run right before the transaction is actually finalized. Any repository change will
be visible to the hook program. This lets you validate the transaction content or
change it. Exit status 0 allows the commit to proceed. A non-zero status will cause
the transaction to be rolled back. The reason for the transaction opening will be
in $HG_TXNNAME, and a unique identifier for the transaction will be in HG_TXNID.
The rest of the available data will vary according the transaction type. New
changesets will add $HG_NODE (the ID of the first added changeset), $HG_NODE_LAST
(the ID of the last added changeset), $HG_URL and $HG_SOURCE variables. Bookmark
and phase changes will set HG_BOOKMARK_MOVED and HG_PHASES_MOVED to 1 respectively,
etc.
pretxnclose-bookmark
Run right before a bookmark change is actually finalized. Any repository change
will be visible to the hook program. This lets you validate the transaction content
or change it. Exit status 0 allows the commit to proceed. A non-zero status will
cause the transaction to be rolled back. The name of the bookmark will be
available in $HG_BOOKMARK, the new bookmark location will be available in $HG_NODE
while the previous location will be available in $HG_OLDNODE. In case of a bookmark
creation $HG_OLDNODE will be empty. In case of deletion $HG_NODE will be empty. In
addition, the reason for the transaction opening will be in $HG_TXNNAME, and a
unique identifier for the transaction will be in HG_TXNID.
pretxnclose-phase
Run right before a phase change is actually finalized. Any repository change will
be visible to the hook program. This lets you validate the transaction content or
change it. Exit status 0 allows the commit to proceed. A non-zero status will
cause the transaction to be rolled back. The hook is called multiple times, once
for each revision affected by a phase change. The affected node is available in
$HG_NODE, the phase in $HG_PHASE while the previous $HG_OLDPHASE. In case of new
node, $HG_OLDPHASE will be empty. In addition, the reason for the transaction
opening will be in $HG_TXNNAME, and a unique identifier for the transaction will be
in HG_TXNID. The hook is also run for newly added revisions. In this case the
$HG_OLDPHASE entry will be empty.
txnclose
Run after any repository transaction has been committed. At this point, the
transaction can no longer be rolled back. The hook will run after the lock is
released. See hg help config.hooks.pretxnclose for details about available
variables.
txnclose-bookmark
Run after any bookmark change has been committed. At this point, the transaction
can no longer be rolled back. The hook will run after the lock is released. See hg
help config.hooks.pretxnclose-bookmark for details about available variables.
txnclose-phase
Run after any phase change has been committed. At this point, the transaction can
no longer be rolled back. The hook will run after the lock is released. See hg help
config.hooks.pretxnclose-phase for details about available variables.
txnabort
Run when a transaction is aborted. See hg help config.hooks.pretxnclose for details
about available variables.
pretxnchangegroup
Run after a changegroup has been added via push, pull or unbundle, but before the
transaction has been committed. The changegroup is visible to the hook program.
This allows validation of incoming changes before accepting them. The ID of the
first new changeset is in $HG_NODE and last is in $HG_NODE_LAST. Exit status 0
allows the transaction to commit. A non-zero status will cause the transaction to
be rolled back, and the push, pull or unbundle will fail. The URL that was the
source of changes is in $HG_URL.
pretxncommit
Run after a changeset has been created, but before the transaction is committed.
The changeset is visible to the hook program. This allows validation of the commit
message and changes. Exit status 0 allows the commit to proceed. A non-zero status
will cause the transaction to be rolled back. The ID of the new changeset is in
$HG_NODE. The parent changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
preupdate
Run before updating the working directory. Exit status 0 allows the update to
proceed. A non-zero status will prevent the update. The changeset ID of first new
parent is in $HG_PARENT1. If updating to a merge, the ID of second new parent is in
$HG_PARENT2.
listkeys
Run after listing pushkeys (like bookmarks) in the repository. The key namespace is
in $HG_NAMESPACE. $HG_VALUES is a dictionary containing the keys and values.
pushkey
Run after a pushkey (like a bookmark) is added to the repository. The key namespace
is in $HG_NAMESPACE, the key is in $HG_KEY, the old value (if any) is in $HG_OLD,
and the new value is in $HG_NEW.
tag
Run after a tag is created. The ID of the tagged changeset is in $HG_NODE. The
name of tag is in $HG_TAG. The tag is local if $HG_LOCAL=1, or in the repository if
$HG_LOCAL=0.
update
Run after updating the working directory. The changeset ID of first new parent is
in $HG_PARENT1. If updating to a merge, the ID of second new parent is in
$HG_PARENT2. If the update succeeded, $HG_ERROR=0. If the update failed (e.g.
because conflicts were not resolved), $HG_ERROR=1.
Note It is generally better to use standard hooks rather than the generic pre- and post-
command hooks, as they are guaranteed to be called in the appropriate contexts for
influencing transactions. Also, hooks like "commit" will be called in all contexts
that generate a commit (e.g. tag) and not just the commit command.
Note Environment variables with empty values may not be passed to hooks on platforms
such as Windows. As an example, $HG_PARENT2 will have an empty value under
Unix-like platforms for non-merge changesets, while it will not be available at all
under Windows.
The syntax for Python hooks is as follows:
hookname = python:modulename.submodule.callable
hookname = python:/path/to/python/module.py:callable
Python hooks are run within the Mercurial process. Each hook is called with at least three
keyword arguments: a ui object (keyword ui), a repository object (keyword repo), and a
hooktype keyword that tells what kind of hook is used. Arguments listed as environment
variables above are passed as keyword arguments, with no HG_ prefix, and names in lower
case.
If a Python hook returns a "true" value or raises an exception, this is treated as a
failure.
hostfingerprints
(Deprecated. Use [hostsecurity]'s fingerprints options instead.)
Fingerprints of the certificates of known HTTPS servers.
A HTTPS connection to a server with a fingerprint configured here will only succeed if the
servers certificate matches the fingerprint. This is very similar to how ssh known hosts
works.
The fingerprint is the SHA-1 hash value of the DER encoded certificate. Multiple values
can be specified (separated by spaces or commas). This can be used to define both old and
new fingerprints while a host transitions to a new certificate.
The CA chain and web.cacerts is not used for servers with a fingerprint.
For example:
[hostfingerprints]
hg.intevation.de = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hg.intevation.org = fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hostsecurity
Used to specify global and per-host security settings for connecting to other machines.
The following options control default behavior for all hosts.
ciphers
Defines the cryptographic ciphers to use for connections.
Value must be a valid OpenSSL Cipher List Format as documented at
https://www.openssl.org/docs/manmaster/apps/ciphers.html#CIPHER-LIST-FORMAT.
This setting is for advanced users only. Setting to incorrect values can
significantly lower connection security or decrease performance. You have been
warned.
This option requires Python 2.7.
minimumprotocol
Defines the minimum channel encryption protocol to use.
By default, the highest version of TLS supported by both client and server is used.
Allowed values are: tls1.0, tls1.1, tls1.2.
When running on an old Python version, only tls1.0 is allowed since old versions of
Python only support up to TLS 1.0.
When running a Python that supports modern TLS versions, the default is tls1.1.
tls1.0 can still be used to allow TLS 1.0. However, this weakens security and
should only be used as a feature of last resort if a server does not support TLS
1.1+.
Options in the [hostsecurity] section can have the form hostname:setting. This allows
multiple settings to be defined on a per-host basis.
The following per-host settings can be defined.
ciphers
This behaves like ciphers as described above except it only applies to the host on
which it is defined.
fingerprints
A list of hashes of the DER encoded peer/remote certificate. Values have the form
algorithm:fingerprint. e.g.
sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2. In
addition, colons (:) can appear in the fingerprint part.
The following algorithms/prefixes are supported: sha1, sha256, sha512.
Use of sha256 or sha512 is preferred.
If a fingerprint is specified, the CA chain is not validated for this host and
Mercurial will require the remote certificate to match one of the fingerprints
specified. This means if the server updates its certificate, Mercurial will abort
until a new fingerprint is defined. This can provide stronger security than
traditional CA-based validation at the expense of convenience.
This option takes precedence over verifycertsfile.
minimumprotocol
This behaves like minimumprotocol as described above except it only applies to the
host on which it is defined.
verifycertsfile
Path to file a containing a list of PEM encoded certificates used to verify the
server certificate. Environment variables and ~user constructs are expanded in the
filename.
The server certificate or the certificate's certificate authority (CA) must match a
certificate from this file or certificate verification will fail and connections to
the server will be refused.
If defined, only certificates provided by this file will be used: web.cacerts and
any system/default certificates will not be used.
This option has no effect if the per-host fingerprints option is set.
The format of the file is as follows:
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
For example:
[hostsecurity]
hg.example.com:fingerprints = sha256:c3ab8ff13720e8ad9047dd39466b3c8974e592c2fa383d4a3960714caef0c4f2
hg2.example.com:fingerprints = sha1:914f1aff87249c09b6859b88b1906d30756491ca, sha1:fc:e2:8d:d9:51:cd:cb:c1:4d:18:6b:b7:44:8d:49:72:57:e6:cd:33
hg3.example.com:fingerprints = sha256:9a:b0:dc:e2:75:ad:8a:b7:84:58:e5:1f:07:32:f1:87:e6:bd:24:22:af:b7:ce:8e:9c:b4:10:cf:b9:f4:0e:d2
foo.example.com:verifycertsfile = /etc/ssl/trusted-ca-certs.pem
To change the default minimum protocol version to TLS 1.2 but to allow TLS 1.1 when
connecting to hg.example.com:
[hostsecurity]
minimumprotocol = tls1.2
hg.example.com:minimumprotocol = tls1.1
http_proxy
Used to access web-based Mercurial repositories through a HTTP proxy.
host
Host name and (optional) port of the proxy server, for example "myproxy:8000".
no
Optional. Comma-separated list of host names that should bypass the proxy.
passwd
Optional. Password to authenticate with at the proxy server.
user
Optional. User name to authenticate with at the proxy server.
always
Optional. Always use the proxy, even for localhost and any entries in
http_proxy.no. (default: False)
http
Used to configure access to Mercurial repositories via HTTP.
timeout
If set, blocking operations will timeout after that many seconds. (default: None)
merge
This section specifies behavior during merges and updates.
checkignored
Controls behavior when an ignored file on disk has the same name as a tracked file
in the changeset being merged or updated to, and has different contents. Options
are abort, warn and ignore. With abort, abort on such files. With warn, warn on
such files and back them up as .orig. With ignore, don't print a warning and back
them up as .orig. (default: abort)
checkunknown
Controls behavior when an unknown file that isn't ignored has the same name as a
tracked file in the changeset being merged or updated to, and has different
contents. Similar to merge.checkignored, except for files that are not ignored.
(default: abort)
on-failure
When set to continue (the default), the merge process attempts to merge all
unresolved files using the merge chosen tool, regardless of whether previous file
merge attempts during the process succeeded or not. Setting this to prompt will
prompt after any merge failure continue or halt the merge process. Setting this to
halt will automatically halt the merge process on any merge tool failure. The merge
process can be restarted by using the resolve command. When a merge is halted, the
repository is left in a normal unresolved merge state. (default: continue)
strict-capability-check
Whether capabilities of internal merge tools are checked strictly or not, while
examining rules to decide merge tool to be used. (default: False)
merge-patterns
This section specifies merge tools to associate with particular file patterns. Tools
matched here will take precedence over the default merge tool. Patterns are globs by
default, rooted at the repository root.
Example:
[merge-patterns]
**.c = kdiff3
**.jpg = myimgmerge
merge-tools
This section configures external merge tools to use for file-level merges. This section
has likely been preconfigured at install time. Use hg config merge-tools to check the
existing configuration. Also see hg help merge-tools for more details.
Example ~/.hgrc:
[merge-tools]
# Override stock tool location
kdiff3.executable = ~/bin/kdiff3
# Specify command line
kdiff3.args = $base $local $other -o $output
# Give higher priority
kdiff3.priority = 1
# Changing the priority of preconfigured tool
meld.priority = 0
# Disable a preconfigured tool
vimdiff.disabled = yes
# Define new tool
myHtmlTool.args = -m $local $other $base $output
myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
myHtmlTool.priority = 1
Supported arguments:
priority
The priority in which to evaluate this tool. (default: 0)
executable
Either just the name of the executable or its pathname.
On Windows, the path can use environment variables with ${ProgramFiles} syntax.
(default: the tool name)
args
The arguments to pass to the tool executable. You can refer to the files being
merged as well as the output file through these variables: $base, $local, $other,
$output.
The meaning of $local and $other can vary depending on which action is being
performed. During an update or merge, $local represents the original state of the
file, while $other represents the commit you are updating to or the commit you are
merging with. During a rebase, $local represents the destination of the rebase, and
$other represents the commit being rebased.
Some operations define custom labels to assist with identifying the revisions,
accessible via $labellocal, $labelother, and $labelbase. If custom labels are not
available, these will be local, other, and base, respectively. (default: $local
$base $other)
premerge
Attempt to run internal non-interactive 3-way merge tool before launching external
tool. Options are true, false, keep or keep-merge3. The keep option will leave
markers in the file if the premerge fails. The keep-merge3 will do the same but
include information about the base of the merge in the marker (see internal :merge3
in hg help merge-tools). (default: True)
binary
This tool can merge binary files. (default: False, unless tool was selected by file
pattern match)
symlink
This tool can merge symlinks. (default: False)
check
A list of merge success-checking options:
changed
Ask whether merge was successful when the merged file shows no changes.
conflicts
Check whether there are conflicts even though the tool reported success.
prompt
Always prompt for merge success, regardless of success reported by tool.
fixeol
Attempt to fix up EOL changes caused by the merge tool. (default: False)
gui
This tool requires a graphical interface to run. (default: False)
mergemarkers
Controls whether the labels passed via $labellocal, $labelother, and $labelbase are
detailed (respecting mergemarkertemplate) or basic. If premerge is keep or
keep-merge3, the conflict markers generated during premerge will be detailed if
either this option or the corresponding option in the [ui] section is detailed.
(default: basic)
mergemarkertemplate
This setting can be used to override mergemarkertemplate from the [ui] section on a
per-tool basis; this applies to the $label-prefixed variables and to the conflict
markers that are generated if premerge is keep` or ``keep-merge3. See the
corresponding variable in [ui] for more information.
regkey
Windows registry key which describes install location of this tool. Mercurial will
search for this key first under HKEY_CURRENT_USER and then under
HKEY_LOCAL_MACHINE. (default: None)
regkeyalt
An alternate Windows registry key to try if the first key is not found. The
alternate key uses the same regname and regappend semantics of the primary key.
The most common use for this key is to search for 32bit applications on 64bit
operating systems. (default: None)
regname
Name of value to read from specified registry key. (default: the unnamed (default)
value)
regappend
String to append to the value read from the registry, typically the executable name
of the tool. (default: None)
pager
Setting used to control when to paginate and with what external tool. See hg help pager
for details.
pager
Define the external tool used as pager.
If no pager is set, Mercurial uses the environment variable $PAGER. If neither
pager.pager, nor $PAGER is set, a default pager will be used, typically less on
Unix and more on Windows. Example:
[pager]
pager = less -FRX
ignore
List of commands to disable the pager for. Example:
[pager]
ignore = version, help, update
patch
Settings used when applying patches, for instance through the 'import' command or with
Mercurial Queues extension.
eol
When set to 'strict' patch content and patched files end of lines are preserved.
When set to lf or crlf, both files end of lines are ignored when patching and the
result line endings are normalized to either LF (Unix) or CRLF (Windows). When set
to auto, end of lines are again ignored while patching but line endings in patched
files are normalized to their original setting on a per-file basis. If target file
does not exist or has no end of line, patch line endings are preserved. (default:
strict)
fuzz
The number of lines of 'fuzz' to allow when applying patches. This controls how
much context the patcher is allowed to ignore when trying to apply a patch.
(default: 2)
paths
Assigns symbolic names and behavior to repositories.
Options are symbolic names defining the URL or directory that is the location of the
repository. Example:
[paths]
my_server = https://example.com/my_repo
local_path = /home/me/repo
These symbolic names can be used from the command line. To pull from my_server: hg pull
my_server. To push to local_path: hg push local_path.
Options containing colons (:) denote sub-options that can influence behavior for that
specific path. Example:
[paths]
my_server = https://example.com/my_path
my_server:pushurl = ssh://example.com/my_path
The following sub-options can be defined:
pushurl
The URL to use for push operations. If not defined, the location defined by the
path's main entry is used.
pushrev
A revset defining which revisions to push by default.
When hg push is executed without a -r argument, the revset defined by this
sub-option is evaluated to determine what to push.
For example, a value of . will push the working directory's revision by default.
Revsets specifying bookmarks will not result in the bookmark being pushed.
The following special named paths exist:
default
The URL or directory to use when no source or remote is specified.
hg clone will automatically define this path to the location the repository was
cloned from.
default-push
(deprecated) The URL or directory for the default hg push location.
default:pushurl should be used instead.
phases
Specifies default handling of phases. See hg help phases for more information about
working with phases.
publish
Controls draft phase behavior when working as a server. When true, pushed
changesets are set to public in both client and server and pulled or cloned
changesets are set to public in the client. (default: True)
new-commit
Phase of newly-created commits. (default: draft)
checksubrepos
Check the phase of the current revision of each subrepository. Allowed values are
"ignore", "follow" and "abort". For settings other than "ignore", the phase of the
current revision of each subrepository is checked before committing the parent
repository. If any of those phases is greater than the phase of the parent
repository (e.g. if a subrepo is in a "secret" phase while the parent repo is in
"draft" phase), the commit is either aborted (if checksubrepos is set to "abort")
or the higher phase is used for the parent repository commit (if set to "follow").
(default: follow)
profiling
Specifies profiling type, format, and file output. Two profilers are supported: an
instrumenting profiler (named ls), and a sampling profiler (named stat).
In this section description, 'profiling data' stands for the raw data collected during
profiling, while 'profiling report' stands for a statistical text report generated from
the profiling data.
enabled
Enable the profiler. (default: false)
This is equivalent to passing --profile on the command line.
type
The type of profiler to use. (default: stat)
ls
Use Python's built-in instrumenting profiler. This profiler works on all
platforms, but each line number it reports is the first line of a function.
This restriction makes it difficult to identify the expensive parts of a
non-trivial function.
stat
Use a statistical profiler, statprof. This profiler is most useful for
profiling commands that run for longer than about 0.1 seconds.
format
Profiling format. Specific to the ls instrumenting profiler. (default: text)
text
Generate a profiling report. When saving to a file, it should be noted that
only the report is saved, and the profiling data is not kept.
kcachegrind
Format profiling data for kcachegrind use: when saving to a file, the
generated file can directly be loaded into kcachegrind.
statformat
Profiling format for the stat profiler. (default: hotpath)
hotpath
Show a tree-based display containing the hot path of execution (where most
time was spent).
bymethod
Show a table of methods ordered by how frequently they are active.
byline
Show a table of lines in files ordered by how frequently they are active.
json
Render profiling data as JSON.
frequency
Sampling frequency. Specific to the stat sampling profiler. (default: 1000)
output
File path where profiling data or report should be saved. If the file exists, it is
replaced. (default: None, data is printed on stderr)
sort
Sort field. Specific to the ls instrumenting profiler. One of callcount,
reccallcount, totaltime and inlinetime. (default: inlinetime)
time-track
Control if the stat profiler track cpu or real time. (default: cpu on Windows,
otherwise real)
limit
Number of lines to show. Specific to the ls instrumenting profiler. (default: 30)
nested
Show at most this number of lines of drill-down info after each main entry. This
can help explain the difference between Total and Inline. Specific to the ls
instrumenting profiler. (default: 0)
showmin
Minimum fraction of samples an entry must have for it to be displayed. Can be
specified as a float between 0.0 and 1.0 or can have a % afterwards to allow values
up to 100. e.g. 5%.
Only used by the stat profiler.
For the hotpath format, default is 0.05. For the chrome format, default is 0.005.
The option is unused on other formats.
showmax
Maximum fraction of samples an entry can have before it is ignored in display.
Values format is the same as showmin.
Only used by the stat profiler.
For the chrome format, default is 0.999.
The option is unused on other formats.
showtime
Show time taken as absolute durations, in addition to percentages. Only used by
the hotpath format. (default: true)
progress
Mercurial commands can draw progress bars that are as informative as possible. Some
progress bars only offer indeterminate information, while others have a definite end
point.
debug
Whether to print debug info when updating the progress bar. (default: False)
delay
Number of seconds (float) before showing the progress bar. (default: 3)
changedelay
Minimum delay before showing a new topic. When set to less than 3 * refresh, that
value will be used instead. (default: 1)
estimateinterval
Maximum sampling interval in seconds for speed and estimated time calculation.
(default: 60)
refresh
Time in seconds between refreshes of the progress bar. (default: 0.1)
format
Format of the progress bar.
Valid entries for the format field are topic, bar, number, unit, estimate, speed,
and item. item defaults to the last 20 characters of the item, but this can be
changed by adding either -<num> which would take the last num characters, or +<num>
for the first num characters.
(default: topic bar number estimate)
width
If set, the maximum width of the progress information (that is, min(width, term
width) will be used).
clear-complete
Clear the progress bar after it's done. (default: True)
disable
If true, don't show a progress bar.
assume-tty
If true, ALWAYS show a progress bar, unless disable is given.
rebase
evolution.allowdivergence
Default to False, when True allow creating divergence when performing rebase of
obsolete changesets.
revsetalias
Alias definitions for revsets. See hg help revsets for details.
rewrite
backup-bundle
Whether to save stripped changesets to a bundle file. (default: True)
update-timestamp
If true, updates the date and time of the changeset to current. It is only
applicable for hg amend, hg commit --amend and hg uncommit in the current version.
storage
Control the strategy Mercurial uses internally to store history. Options in this category
impact performance and repository size.
revlog.optimize-delta-parent-choice
When storing a merge revision, both parents will be equally considered as a
possible delta base. This results in better delta selection and improved revlog
compression. This option is enabled by default.
Turning this option off can result in large increase of repository size for
repository with many merges.
revlog.reuse-external-delta-parent
Control the order in which delta parents are considered when adding new revisions
from an external source. (typically: apply bundle from hg pull or hg push).
New revisions are usually provided as a delta against other revisions. By default,
Mercurial will try to reuse this delta first, therefore using the same "delta
parent" as the source. Directly using delta's from the source reduces CPU usage and
usually speeds up operation. However, in some case, the source might have
sub-optimal delta bases and forcing their reevaluation is useful. For example,
pushes from an old client could have sub-optimal delta's parent that the server
want to optimize. (lack of general delta, bad parents, choice, lack of
sparse-revlog, etc).
This option is enabled by default. Turning it off will ensure bad delta parent
choices from older client do not propagate to this repository, at the cost of a
small increase in CPU consumption.
Note: this option only control the order in which delta parents are considered.
Even when disabled, the existing delta from the source will be reused if the same
delta parent is selected.
revlog.reuse-external-delta
Control the reuse of delta from external source. (typically: apply bundle from hg
pull or hg push).
New revisions are usually provided as a delta against another revision. By default,
Mercurial will not recompute the same delta again, trusting externally provided
deltas. There have been rare cases of small adjustment to the diffing algorithm in
the past. So in some rare case, recomputing delta provided by ancient clients can
provides better results. Disabling this option means going through a full delta
recomputation for all incoming revisions. It means a large increase in CPU usage
and will slow operations down.
This option is enabled by default. When disabled, it also disables the related
storage.revlog.reuse-external-delta-parent option.
revlog.zlib.level
Zlib compression level used when storing data into the repository. Accepted Value
range from 1 (lowest compression) to 9 (highest compression). Zlib default value is
6.
revlog.zstd.level
zstd compression level used when storing data into the repository. Accepted Value
range from 1 (lowest compression) to 22 (highest compression). (default 3)
server
Controls generic server settings.
bookmarks-pushkey-compat
Trigger pushkey hook when being pushed bookmark updates. This config exist for
compatibility purpose (default to True)
If you use pushkey and pre-pushkey hooks to control bookmark movement we recommend
you migrate them to txnclose-bookmark and pretxnclose-bookmark.
compressionengines
List of compression engines and their relative priority to advertise to clients.
The order of compression engines determines their priority, the first having the
highest priority. If a compression engine is not listed here, it won't be
advertised to clients.
If not set (the default), built-in defaults are used. Run hg debuginstall to list
available compression engines and their default wire protocol priority.
Older Mercurial clients only support zlib compression and this setting has no
effect for legacy clients.
uncompressed
Whether to allow clients to clone a repository using the uncompressed streaming
protocol. This transfers about 40% more data than a regular clone, but uses less
memory and CPU on both server and client. Over a LAN (100 Mbps or better) or a very
fast WAN, an uncompressed streaming clone is a lot faster (~10x) than a regular
clone. Over most WAN connections (anything slower than about 6 Mbps), uncompressed
streaming is slower, because of the extra data transfer overhead. This mode will
also temporarily hold the write lock while determining what data to transfer.
(default: True)
uncompressedallowsecret
Whether to allow stream clones when the repository contains secret changesets.
(default: False)
preferuncompressed
When set, clients will try to use the uncompressed streaming protocol. (default:
False)
disablefullbundle
When set, servers will refuse attempts to do pull-based clones. If this option is
set, preferuncompressed and/or clone bundles are highly recommended. Partial clones
will still be allowed. (default: False)
streamunbundle
When set, servers will apply data sent from the client directly, otherwise it will
be written to a temporary file first. This option effectively prevents concurrent
pushes.
pullbundle
When set, the server will check pullbundle.manifest for bundles covering the
requested heads and common nodes. The first matching entry will be streamed to the
client.
For HTTP transport, the stream will still use zlib compression for older clients.
concurrent-push-mode
Level of allowed race condition between two pushing clients.
• 'strict': push is abort if another client touched the repository while the push
was preparing. (default)
• 'check-related': push is only aborted if it affects head that got also affected
while the push was preparing.
This requires compatible client (version 4.3 and later). Old client will use
'strict'.
validate
Whether to validate the completeness of pushed changesets by checking that all new
file revisions specified in manifests are present. (default: False)
maxhttpheaderlen
Instruct HTTP clients not to send request headers longer than this many bytes.
(default: 1024)
bundle1
Whether to allow clients to push and pull using the legacy bundle1 exchange format.
(default: True)
bundle1gd
Like bundle1 but only used if the repository is using the generaldelta storage
format. (default: True)
bundle1.push
Whether to allow clients to push using the legacy bundle1 exchange format.
(default: True)
bundle1gd.push
Like bundle1.push but only used if the repository is using the generaldelta storage
format. (default: True)
bundle1.pull
Whether to allow clients to pull using the legacy bundle1 exchange format.
(default: True)
bundle1gd.pull
Like bundle1.pull but only used if the repository is using the generaldelta storage
format. (default: True)
Large repositories using the generaldelta storage format should consider setting
this option because converting generaldelta repositories to the exchange format
required by the bundle1 data format can consume a lot of CPU.
bundle2.stream
Whether to allow clients to pull using the bundle2 streaming protocol. (default:
True)
zliblevel
Integer between -1 and 9 that controls the zlib compression level for wire protocol
commands that send zlib compressed output (notably the commands that send
repository history data).
The default (-1) uses the default zlib compression level, which is likely
equivalent to 6. 0 means no compression. 9 means maximum compression.
Setting this option allows server operators to make trade-offs between bandwidth
and CPU used. Lowering the compression lowers CPU utilization but sends more bytes
to clients.
This option only impacts the HTTP server.
zstdlevel
Integer between 1 and 22 that controls the zstd compression level for wire protocol
commands. 1 is the minimal amount of compression and 22 is the highest amount of
compression.
The default (3) should be significantly faster than zlib while likely delivering
better compression ratios.
This option only impacts the HTTP server.
See also server.zliblevel.
view
Repository filter used when exchanging revisions with the peer.
The default view (served) excludes secret and hidden changesets. Another useful
value is immutable (no draft, secret or hidden changesets). (EXPERIMENTAL)
smtp
Configuration for extensions that need to send email messages.
host
Host name of mail server, e.g. "mail.example.com".
port
Optional. Port to connect to on mail server. (default: 465 if tls is smtps; 25
otherwise)
tls
Optional. Method to enable TLS when connecting to mail server: starttls, smtps or
none. (default: none)
username
Optional. User name for authenticating with the SMTP server. (default: None)
password
Optional. Password for authenticating with the SMTP server. If not specified,
interactive sessions will prompt the user for a password; non-interactive sessions
will fail. (default: None)
local_hostname
Optional. The hostname that the sender can use to identify itself to the MTA.
subpaths
Subrepository source URLs can go stale if a remote server changes name or becomes
temporarily unavailable. This section lets you define rewrite rules of the form:
<pattern> = <replacement>
where pattern is a regular expression matching a subrepository source URL and replacement
is the replacement string used to rewrite it. Groups can be matched in pattern and
referenced in replacements. For instance:
http://server/(.*)-hg/ = http://hg.server/\1/
rewrites http://server/foo-hg/ into http://hg.server/foo/.
Relative subrepository paths are first made absolute, and the rewrite rules are then
applied on the full (absolute) path. If pattern doesn't match the full path, an attempt is
made to apply it on the relative path alone. The rules are applied in definition order.
subrepos
This section contains options that control the behavior of the subrepositories feature.
See also hg help subrepos.
Security note: auditing in Mercurial is known to be insufficient to prevent clone-time
code execution with carefully constructed Git subrepos. It is unknown if a similar detect
is present in Subversion subrepos. Both Git and Subversion subrepos are disabled by
default out of security concerns. These subrepo types can be enabled using the respective
options below.
allowed
Whether subrepositories are allowed in the working directory.
When false, commands involving subrepositories (like hg update) will fail for all
subrepository types. (default: true)
hg:allowed
Whether Mercurial subrepositories are allowed in the working directory. This option
only has an effect if subrepos.allowed is true. (default: true)
git:allowed
Whether Git subrepositories are allowed in the working directory. This option only
has an effect if subrepos.allowed is true.
See the security note above before enabling Git subrepos. (default: false)
svn:allowed
Whether Subversion subrepositories are allowed in the working directory. This
option only has an effect if subrepos.allowed is true.
See the security note above before enabling Subversion subrepos. (default: false)
templatealias
Alias definitions for templates. See hg help templates for details.
templates
Use the [templates] section to define template strings. See hg help templates for
details.
trusted
Mercurial will not use the settings in the .hg/hgrc file from a repository if it doesn't
belong to a trusted user or to a trusted group, as various hgrc features allow arbitrary
commands to be run. This issue is often encountered when configuring hooks or extensions
for shared repositories or servers. However, the web interface will use some safe settings
from the [web] section.
This section specifies what users and groups are trusted. The current user is always
trusted. To trust everybody, list a user or a group with name *. These settings must be
placed in an already-trusted file to take effect, such as $HOME/.hgrc of the user or
service running Mercurial.
users
Comma-separated list of trusted users.
groups
Comma-separated list of trusted groups.
ui
User interface controls.
archivemeta
Whether to include the .hg_archival.txt file containing meta data (hashes for the
repository base and for tip) in archives created by the hg archive command or
downloaded via hgweb. (default: True)
askusername
Whether to prompt for a username when committing. If True, and neither $HGUSER nor
$EMAIL has been specified, then the user will be prompted to enter a username. If
no username is entered, the default USER@HOST is used instead. (default: False)
clonebundles
Whether the "clone bundles" feature is enabled.
When enabled, hg clone may download and apply a server-advertised bundle file from
a URL instead of using the normal exchange mechanism.
This can likely result in faster and more reliable clones.
(default: True)
clonebundlefallback
Whether failure to apply an advertised "clone bundle" from a server should result
in fallback to a regular clone.
This is disabled by default because servers advertising "clone bundles" often do so
to reduce server load. If advertised bundles start mass failing and clients
automatically fall back to a regular clone, this would add significant and
unexpected load to the server since the server is expecting clone operations to be
offloaded to pre-generated bundles. Failing fast (the default behavior) ensures
clients don't overwhelm the server when "clone bundle" application fails.
(default: False)
clonebundleprefers
Defines preferences for which "clone bundles" to use.
Servers advertising "clone bundles" may advertise multiple available bundles. Each
bundle may have different attributes, such as the bundle type and compression
format. This option is used to prefer a particular bundle over another.
The following keys are defined by Mercurial:
BUNDLESPEC
A bundle type specifier. These are strings passed to hg bundle -t. e.g.
gzip-v2 or bzip2-v1.
COMPRESSION
The compression format of the bundle. e.g. gzip and bzip2.
Server operators may define custom keys.
Example values: COMPRESSION=bzip2, BUNDLESPEC=gzip-v2, COMPRESSION=gzip.
By default, the first bundle advertised by the server is used.
color
When to colorize output. Possible value are Boolean ("yes" or "no"), or "debug", or
"always". (default: "yes"). "yes" will use color whenever it seems possible. See hg
help color for details.
commitsubrepos
Whether to commit modified subrepositories when committing the parent repository.
If False and one subrepository has uncommitted changes, abort the commit.
(default: False)
debug
Print debugging information. (default: False)
editor
The editor to use during a commit. (default: $EDITOR or vi)
fallbackencoding
Encoding to try if it's not possible to decode the changelog using UTF-8. (default:
ISO-8859-1)
graphnodetemplate
The template used to print changeset nodes in an ASCII revision graph. (default:
{graphnode})
ignore
A file to read per-user ignore patterns from. This file should be in the same
format as a repository-wide .hgignore file. Filenames are relative to the
repository root. This option supports hook syntax, so if you want to specify
multiple ignore files, you can do so by setting something like ignore.other =
~/.hgignore2. For details of the ignore file format, see the hgignore(5) man page.
interactive
Allow to prompt the user. (default: True)
interface
Select the default interface for interactive features (default: text). Possible
values are 'text' and 'curses'.
interface.chunkselector
Select the interface for change recording (e.g. hg commit -i). Possible values are
'text' and 'curses'. This config overrides the interface specified by
ui.interface.
large-file-limit
Largest file size that gives no memory use warning. Possible values are integers
or 0 to disable the check. (default: 10000000)
logtemplate
Template string for commands that print changesets.
merge
The conflict resolution program to use during a manual merge. For more information
on merge tools see hg help merge-tools. For configuring merge tools see the
[merge-tools] section.
mergemarkers
Sets the merge conflict marker label styling. The detailed style uses the
mergemarkertemplate setting to style the labels. The basic style just uses 'local'
and 'other' as the marker label. One of basic or detailed. (default: basic)
mergemarkertemplate
The template used to print the commit description next to each conflict marker
during merge conflicts. See hg help templates for the template format.
Defaults to showing the hash, tags, branches, bookmarks, author, and the first line
of the commit description.
If you use non-ASCII characters in names for tags, branches, bookmarks, authors,
and/or commit descriptions, you must pay attention to encodings of managed files.
At template expansion, non-ASCII characters use the encoding specified by the
--encoding global option, HGENCODING or other environment variables that govern
your locale. If the encoding of the merge markers is different from the encoding of
the merged files, serious problems may occur.
Can be overridden per-merge-tool, see the [merge-tools] section.
message-output
Where to write status and error messages. (default: stdio)
stderr
Everything to stderr.
stdio
Status to stdout, and error to stderr.
origbackuppath
The path to a directory used to store generated .orig files. If the path is not a
directory, one will be created. If set, files stored in this directory have the
same name as the original file and do not have a .orig suffix.
paginate
Control the pagination of command output (default: True). See hg help pager for
details.
patch
An optional external tool that hg import and some extensions will use for applying
patches. By default Mercurial uses an internal patch utility. The external tool
must work as the common Unix patch program. In particular, it must accept a -p
argument to strip patch headers, a -d argument to specify the current directory, a
file name to patch, and a patch file to take from stdin.
It is possible to specify a patch tool together with extra arguments. For example,
setting this option to patch --merge will use the patch program with its 2-way
merge option.
portablefilenames
Check for portable filenames. Can be warn, ignore or abort. (default: warn)
warn
Print a warning message on POSIX platforms, if a file with a non-portable
filename is added (e.g. a file with a name that can't be created on Windows
because it contains reserved parts like AUX, reserved characters like :, or
would cause a case collision with an existing file).
ignore
Don't print a warning.
abort
The command is aborted.
true
Alias for warn.
false
Alias for ignore.
On Windows, this configuration option is ignored and the command aborted.
pre-merge-tool-output-template
A template that is printed before executing an external merge tool. This can be
used to print out additional context that might be useful to have during the
conflict resolution, such as the description of the various commits involved or
bookmarks/tags.
Additional information is available in the local`, ``base, and other dicts. For
example: {local.label}, {base.name}, or {other.islink}.
quiet
Reduce the amount of output printed. (default: False)
relative-paths
Prefer relative paths in the UI.
remotecmd
Remote command to use for clone/push/pull operations. (default: hg)
report_untrusted
Warn if a .hg/hgrc file is ignored due to not being owned by a trusted user or
group. (default: True)
slash
(Deprecated. Use slashpath template filter instead.)
Display paths using a slash (/) as the path separator. This only makes a difference
on systems where the default path separator is not the slash character (e.g.
Windows uses the backslash character (\)). (default: False)
statuscopies
Display copies in the status command.
ssh
Command to use for SSH connections. (default: ssh)
ssherrorhint
A hint shown to the user in the case of SSH error (e.g. Please see
http://company/internalwiki/ssh.html)
strict
Require exact command names, instead of allowing unambiguous abbreviations.
(default: False)
style
Name of style to use for command output.
supportcontact
A URL where users should report a Mercurial traceback. Use this if you are a large
organisation with its own Mercurial deployment process and crash reports should be
addressed to your internal support.
textwidth
Maximum width of help text. A longer line generated by hg help or hg subcommand
--help will be broken after white space to get this width or the terminal width,
whichever comes first. A non-positive value will disable this and the terminal
width will be used. (default: 78)
timeout
The timeout used when a lock is held (in seconds), a negative value means no
timeout. (default: 600)
timeout.warn
Time (in seconds) before a warning is printed about held lock. A negative value
means no warning. (default: 0)
traceback
Mercurial always prints a traceback when an unknown exception occurs. Setting this
to True will make Mercurial print a traceback on all exceptions, even those
recognized by Mercurial (such as IOError or MemoryError). (default: False)
tweakdefaults
By default Mercurial's behavior changes very little from release to release, but over
time the recommended config settings shift. Enable this config to opt in to get
automatic tweaks to Mercurial's behavior over time. This config setting will have no
effect if HGPLAIN is set or HGPLAINEXCEPT is set and does not include tweakdefaults.
(default: False)
It currently means:
[ui]
# The rollback command is dangerous. As a rule, don't use it.
rollback = False
# Make `hg status` report copy information
statuscopies = yes
# Prefer curses UIs when available. Revert to plain-text with `text`.
interface = curses
# Make compatible commands emit cwd-relative paths by default.
relative-paths = yes
[commands]
# Grep working directory by default.
grep.all-files = True
# Refuse to perform an `hg update` that would cause a file content merge
update.check = noconflict
# Show conflicts information in `hg status`
status.verbose = True
# Make `hg resolve` with no action (like `-m`) fail instead of re-merging.
resolve.explicit-re-merge = True
[diff]
git = 1
showfunc = 1
word-diff = 1
username
The committer of a changeset created when running "commit". Typically a person's
name and email address, e.g. Fred Widget <fred@example.com>. Environment variables
in the username are expanded.
(default: $EMAIL or username@hostname. If the username in hgrc is empty, e.g. if
the system admin set username = in the system hgrc, it has to be specified manually
or in a different hgrc file)
verbose
Increase the amount of output printed. (default: False)
web
Web interface configuration. The settings in this section apply to both the builtin
webserver (started by hg serve) and the script you run through a webserver (hgweb.cgi and
the derivatives for FastCGI and WSGI).
The Mercurial webserver does no authentication (it does not prompt for usernames and
passwords to validate who users are), but it does do authorization (it grants or denies
access for authenticated users based on settings in this section). You must either
configure your webserver to do authentication for you, or disable the authorization
checks.
For a quick setup in a trusted environment, e.g., a private LAN, where you want it to
accept pushes from anybody, you can use the following command line:
$ hg --config web.allow-push=* --config web.push_ssl=False serve
Note that this will allow anybody to push anything to the server and that this should not
be used for public servers.
The full set of options is:
accesslog
Where to output the access log. (default: stdout)
address
Interface address to bind to. (default: all)
allow-archive
List of archive format (bz2, gz, zip) allowed for downloading. (default: empty)
allowbz2
(DEPRECATED) Whether to allow .tar.bz2 downloading of repository revisions.
(default: False)
allowgz
(DEPRECATED) Whether to allow .tar.gz downloading of repository revisions.
(default: False)
allow-pull
Whether to allow pulling from the repository. (default: True)
allow-push
Whether to allow pushing to the repository. If empty or not set, pushing is not
allowed. If the special value *, any remote user can push, including
unauthenticated users. Otherwise, the remote user must have been authenticated, and
the authenticated user name must be present in this list. The contents of the
allow-push list are examined after the deny_push list.
allow_read
If the user has not already been denied repository access due to the contents of
deny_read, this list determines whether to grant repository access to the user. If
this list is not empty, and the user is unauthenticated or not present in the list,
then access is denied for the user. If the list is empty or not set, then access is
permitted to all users by default. Setting allow_read to the special value * is
equivalent to it not being set (i.e. access is permitted to all users). The
contents of the allow_read list are examined after the deny_read list.
allowzip
(DEPRECATED) Whether to allow .zip downloading of repository revisions. This
feature creates temporary files. (default: False)
archivesubrepos
Whether to recurse into subrepositories when archiving. (default: False)
baseurl
Base URL to use when publishing URLs in other locations, so third-party tools like
email notification hooks can construct URLs. Example: http://hgserver/repos/.
cacerts
Path to file containing a list of PEM encoded certificate authority certificates.
Environment variables and ~user constructs are expanded in the filename. If
specified on the client, then it will verify the identity of remote HTTPS servers
with these certificates.
To disable SSL verification temporarily, specify --insecure from command line.
You can use OpenSSL's CA certificate file if your platform has one. On most Linux
systems this will be /etc/ssl/certs/ca-certificates.crt. Otherwise you will have to
generate this file manually. The form must be as follows:
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
cache
Whether to support caching in hgweb. (default: True)
certificate
Certificate to use when running hg serve.
collapse
With descend enabled, repositories in subdirectories are shown at a single level
alongside repositories in the current path. With collapse also enabled,
repositories residing at a deeper level than the current path are grouped behind
navigable directory entries that lead to the locations of these repositories. In
effect, this setting collapses each collection of repositories found within a
subdirectory into a single entry for that subdirectory. (default: False)
comparisoncontext
Number of lines of context to show in side-by-side file comparison. If negative or
the value full, whole files are shown. (default: 5)
This setting can be overridden by a context request parameter to the comparison
command, taking the same values.
contact
Name or email address of the person in charge of the repository. (default:
ui.username or $EMAIL or "unknown" if unset or empty)
csp
Send a Content-Security-Policy HTTP header with this value.
The value may contain a special string %nonce%, which will be replaced by a
randomly-generated one-time use value. If the value contains %nonce%, web.cache
will be disabled, as caching undermines the one-time property of the nonce. This
nonce will also be inserted into <script> elements containing inline JavaScript.
Note: lots of HTML content sent by the server is derived from repository data.
Please consider the potential for malicious repository data to "inject" itself into
generated HTML content as part of your security threat model.
deny_push
Whether to deny pushing to the repository. If empty or not set, push is not denied.
If the special value *, all remote users are denied push. Otherwise,
unauthenticated users are all denied, and any authenticated user name present in
this list is also denied. The contents of the deny_push list are examined before
the allow-push list.
deny_read
Whether to deny reading/viewing of the repository. If this list is not empty,
unauthenticated users are all denied, and any authenticated user name present in
this list is also denied access to the repository. If set to the special value *,
all remote users are denied access (rarely needed ;). If deny_read is empty or not
set, the determination of repository access depends on the presence and content of
the allow_read list (see description). If both deny_read and allow_read are empty
or not set, then access is permitted to all users by default. If the repository is
being served via hgwebdir, denied users will not be able to see it in the list of
repositories. The contents of the deny_read list have priority over (are examined
before) the contents of the allow_read list.
descend
hgwebdir indexes will not descend into subdirectories. Only repositories directly
in the current path will be shown (other repositories are still available from the
index corresponding to their containing path).
description
Textual description of the repository's purpose or contents. (default: "unknown")
encoding
Character encoding name. (default: the current locale charset) Example: "UTF-8".
errorlog
Where to output the error log. (default: stderr)
guessmime
Control MIME types for raw download of file content. Set to True to let hgweb
guess the content type from the file extension. This will serve HTML files as
text/html and might allow cross-site scripting attacks when serving untrusted
repositories. (default: False)
hidden
Whether to hide the repository in the hgwebdir index. (default: False)
ipv6
Whether to use IPv6. (default: False)
labels
List of string labels associated with the repository.
Labels are exposed as a template keyword and can be used to customize output. e.g.
the index template can group or filter repositories by labels and the summary
template can display additional content if a specific label is present.
logoimg
File name of the logo image that some templates display on each page. The file
name is relative to staticurl. That is, the full path to the logo image is
"staticurl/logoimg". If unset, hglogo.png will be used.
logourl
Base URL to use for logos. If unset, https://mercurial-scm.org/ will be used.
maxchanges
Maximum number of changes to list on the changelog. (default: 10)
maxfiles
Maximum number of files to list per changeset. (default: 10)
maxshortchanges
Maximum number of changes to list on the shortlog, graph or filelog pages.
(default: 60)
name
Repository name to use in the web interface. (default: current working directory)
port
Port to listen on. (default: 8000)
prefix
Prefix path to serve from. (default: '' (server root))
push_ssl
Whether to require that inbound pushes be transported over SSL to prevent password
sniffing. (default: True)
refreshinterval
How frequently directory listings re-scan the filesystem for new repositories, in
seconds. This is relevant when wildcards are used to define paths. Depending on how
much filesystem traversal is required, refreshing may negatively impact
performance.
Values less than or equal to 0 always refresh. (default: 20)
server-header
Value for HTTP Server response header.
static
Directory where static files are served from.
staticurl
Base URL to use for static files. If unset, static files (e.g. the hgicon.png
favicon) will be served by the CGI script itself. Use this setting to serve them
directly with the HTTP server. Example: http://hgserver/static/.
stripes
How many lines a "zebra stripe" should span in multi-line output. Set to 0 to
disable. (default: 1)
style
Which template map style to use. The available options are the names of
subdirectories in the HTML templates path. (default: paper) Example: monoblue.
templates
Where to find the HTML templates. The default path to the HTML templates can be
obtained from hg debuginstall.
websub
Web substitution filter definition. You can use this section to define a set of regular
expression substitution patterns which let you automatically modify the hgweb server
output.
The default hgweb templates only apply these substitution patterns on the revision
description fields. You can apply them anywhere you want when you create your own
templates by adding calls to the "websub" filter (usually after calling the "escape"
filter).
This can be used, for example, to convert issue references to links to your issue tracker,
or to convert "markdown-like" syntax into HTML (see the examples below).
Each entry in this section names a substitution filter. The value of each entry defines
the substitution expression itself. The websub expressions follow the old interhg
extension syntax, which in turn imitates the Unix sed replacement syntax:
patternname = s/SEARCH_REGEX/REPLACE_EXPRESSION/[i]
You can use any separator other than "/". The final "i" is optional and indicates that the
search must be case insensitive.
Examples:
[websub]
issues = s|issue(\d+)|<a href="http://bts.example.org/issue\1">issue\1</a>|i
italic = s/\b_(\S+)_\b/<i>\1<\/i>/
bold = s/\*\b(\S+)\b\*/<b>\1<\/b>/
worker
Parallel master/worker configuration. We currently perform working directory updates in
parallel on Unix-like systems, which greatly helps performance.
enabled
Whether to enable workers code to be used. (default: true)
numcpus
Number of CPUs to use for parallel operations. A zero or negative value is treated
as use the default. (default: 4 or the number of CPUs on the system, whichever is
larger)
backgroundclose
Whether to enable closing file handles on background threads during certain
operations. Some platforms aren't very efficient at closing file handles that have
been written or appended to. By performing file closing on background threads, file
write rate can increase substantially. (default: true on Windows, false elsewhere)
backgroundcloseminfilecount
Minimum number of files required to trigger background file closing. Operations
not writing this many files won't start background close threads. (default: 2048)
backgroundclosemaxqueue
The maximum number of opened file handles waiting to be closed in the background.
This option only has an effect if backgroundclose is enabled. (default: 384)
backgroundclosethreadcount
Number of threads to process background file closes. Only relevant if
backgroundclose is enabled. (default: 4)
