hgrc - configuration files for Mercurial
The Mercurial system uses a set of configuration files to control
aspects of its behavior.
Mercurial reads configuration data from several files, if they exist.
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.
(Unix, Windows) <repo>/.hg/hgrc
Per-repository configuration options that 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
Unix, most of this file will be ignored if it doesn't belong to a
trusted user or to a trusted group. See the documentation for the
trusted section below for more details.
Per-user configuration file(s), for the user running Mercurial. On
Windows 9x, %HOME% is replaced by %APPDATA%. 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-system configuration files, 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.
Per-installation configuration files, 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/system configuration files, 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
A configuration file consists of sections, led by a [section] header
and followed by name = value entries:
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.
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.
A line with %unset name will remove name from the current section, if
it has been set previously.
This section describes the different sections that may appear in a
Mercurial "hgrc" file, the purpose of each section, its possible keys,
and their possible values.
Defines command aliases. Aliases allow you to define your own commands
in terms of other commands (or aliases), optionally including
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!
Authentication credentials for HTTP authentication. Each line has the
<name>.<argument> = <value>
where <name> is used to group arguments into authentication entries.
foo.prefix = hg.intevation.org/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
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.
Optional. Username to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it.
Optional. Password to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it.
Optional. PEM encoded client certificate key file.
Optional. PEM encoded client certificate chain file.
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.
If no suitable authentication entry is found, the user is prompted for
credentials as usual if required by the remote.
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.
# uncompress gzip files on checkin to improve delta compression
# note: not necessarily a good idea, just an example
*.gz = pipe: gunzip
# 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.
The most common usage is for LF <-> CRLF translation on Windows. For
this, use the "smart" converters which check for binary files:
** = cleverencode:
** = cleverdecode:
or if you only want to translate certain files:
**.txt = dumbencode:
**.txt = dumbdecode:
(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:
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.
Settings used when displaying diffs. They are all Boolean and defaults
Use git extended diff format.
Don't include dates in diff headers.
Show which function each change is in.
Ignore white space when comparing lines.
Ignore changes in the amount of white space.
Ignore changes whose lines are all blank.
Settings for extensions that send email messages.
Optional. Email address to use in "From" header and SMTP
envelope of outgoing messages.
Optional. Comma-separated list of recipients' email addresses.
Optional. Comma-separated list of carbon copy recipients' email
Optional. Comma-separated list of blind carbon copy recipients'
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.
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. Defaults
to empty (explicit) list.
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
from = Joseph User <email@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
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
To explicitly disable an extension that is enabled in an hgrc of
broader scope, prepend its path with !, as in hgext.foo = !/ext/path or
hgext.foo = ! when path is not supplied.
Example for ~/.hgrc:
# (the mq extension will get loaded from Mercurial's path)
# (this extension will get loaded from the file specified)
myfeature = ~/.hgext/myfeature.py
Enable or disable the "store" repository format which improves
compatibility with systems that fold case or otherwise mangle
filenames. Enabled by default. Disabling this option will allow
you to store longer filenames in some situations at the expense
of compatibility and ensures that the on-disk format of newly
created repositories will be compatible with Mercurial before
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". Enabled by default. Disabling this
option ensures that the on-disk format of newly created
repositories will be compatible with Mercurial before version
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
**.c = kdiff3
**.jpg = myimgmerge
This section configures external merge tools to use for file-level
# Override stock tool location
kdiff3.executable = ~/bin/kdiff3
# Specify command line
kdiff3.args = $base $local $other -o $output
# Give higher priority
kdiff3.priority = 1
# Define new tool
myHtmlTool.args = -m $local $other $base $output
myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
myHtmlTool.priority = 1
The priority in which to evaluate this tool. Default: 0.
Either just the name of the executable or its pathname.
Default: the tool name.
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. Default: $local
Attempt to run internal non-interactive 3-way merge tool before
launching external tool. Default: True
This tool can merge binary files. Defaults to False, unless tool
was selected by file pattern match.
This tool can merge symlinks. Defaults to False, even if tool
was selected by file pattern match.
Check whether there are conflicts even though the tool reported
success. Default: False
Check whether outputs were written even though the tool reported
success. Default: False
Attempt to fix up EOL changes caused by the merge tool.
This tool requires a graphical interface to run. Default: False
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:
Name of value to read from specified registry key. Defaults to
the unnamed (default) value.
String to append to the value read from the registry, typically
the executable name of the tool. Default: None
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
# update working directory after adding changesets
changegroup.update = hg update
# do not use the site-wide hook
incoming.email = /my/email/hook
incoming.autobuild = /my/build/hook
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 of the form $HG_foo.
Run after a changegroup has been added via push, pull or
unbundle. ID of the first new changeset is in $HG_NODE. URL
from which changes came is in $HG_URL.
Run after a changeset has been created in the local repository.
ID of the newly created changeset is in $HG_NODE. Parent
changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
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. URL that was source of changes came is in $HG_URL.
Run after sending changes from local repository to another. ID
of first changeset sent is in $HG_NODE. Source of operation is
in $HG_SOURCE; see "preoutgoing" hook for description.
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. Hook failure is ignored.
Run before executing the associated command. The contents of the
command line are passed as $HG_ARGS. If the hook returns
failure, the command doesn't execute and Mercurial returns the
Run before a changegroup is added via push, pull or unbundle.
Exit status 0 allows the changegroup to proceed. Non-zero status
will cause the push, pull or unbundle to fail. URL from which
changes will come is in $HG_URL.
Run before starting a local commit. Exit status 0 allows the
commit to proceed. Non-zero status will cause the commit to
fail. Parent changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
Run before collecting changes to send from the local repository
to another. Non-zero status will cause failure. This lets you
prevent pull over HTTP or SSH. Also prevents against local pull,
push (outbound) or bundle commands, but not effective, since you
can just copy files instead then. Source of operation is in
$HG_SOURCE. If "serve", operation is happening on behalf of
remote SSH or HTTP repository. If "push", "pull" or "bundle",
operation is happening on behalf of repository on same system.
Run before creating a tag. Exit status 0 allows the tag to be
created. Non-zero status will cause the tag to fail. ID of
changeset to tag is in $HG_NODE. Name of tag is in $HG_TAG. Tag
is local if $HG_LOCAL=1, in repository if $HG_LOCAL=0.
Run after a changegroup has been added via push, pull or
unbundle, but before the transaction has been committed.
Changegroup is visible to hook program. This lets you validate
incoming changes before accepting them. Passed the ID of the
first new changeset in $HG_NODE. Exit status 0 allows the
transaction to commit. Non-zero status will cause the
transaction to be rolled back and the push, pull or unbundle
will fail. URL that was source of changes is in $HG_URL.
Run after a changeset has been created but the transaction not
yet committed. Changeset is visible to hook program. This lets
you validate commit message and changes. Exit status 0 allows
the commit to proceed. Non-zero status will cause the
transaction to be rolled back. ID of changeset is in $HG_NODE.
Parent changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
Run before updating the working directory. Exit status 0 allows
the update to proceed. Non-zero status will prevent the update.
Changeset ID of first new parent is in $HG_PARENT1. If merge, ID
of second new parent is in $HG_PARENT2.
Run after a tag is created. ID of tagged changeset is in
$HG_NODE. Name of tag is in $HG_TAG. Tag is local if
$HG_LOCAL=1, in repository if $HG_LOCAL=0.
Run after updating the working directory. Changeset ID of first
new parent is in $HG_PARENT1. If merge, ID of second new parent
is in $HG_PARENT2. If the update succeeded, $HG_ERROR=0. If the
update failed (e.g. because conflicts not resolved),
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
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
If a Python hook returns a "true" value or raises an exception, this is
treated as a failure.
Used to access web-based Mercurial repositories through a HTTP proxy.
Host name and (optional) port of the proxy server, for example
Optional. Comma-separated list of host names that should bypass
Optional. Password to authenticate with at the proxy server.
Optional. User name to authenticate with at the proxy server.
Configuration for extensions that need to send email messages.
Host name of mail server, e.g. "mail.example.com".
Optional. Port to connect to on mail server. Default: 25.
Optional. Whether to connect to mail server using TLS. True or
False. Default: False.
Optional. User name to authenticate to SMTP server with. If
username is specified, password must also be specified.
Optional. Password to authenticate to SMTP server with. If
username is specified, password must also be specified.
Optional. It's the hostname that the sender can use to identify
itself to the MTA.
Settings used when applying patches, for instance through the 'import'
command or with Mercurial Queues extension.
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). Default:
Assigns symbolic names to repositories. The left side is the symbolic
name, and the right gives the directory or URL that is the location of
the repository. Default paths can be declared by setting the following
Directory or URL to use when pulling if no source is specified.
Default is set to repository from which the current repository
Optional. Directory or URL to use when pushing if no destination
Specifies profiling format and file output. 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. The profiling is done using
Profiling format. Default: 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.
Format profiling data for kcachegrind use: when saving to
a file, the generated file can directly be loaded into
File path where profiling data or report should be saved. If the
file exists, it is replaced. Default: None, data is printed on
Controls generic server settings.
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. Default is False.
For security reasons, 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. The main exception is the web interface, which
automatically uses some safe settings, since it's common to serve
repositories from different users.
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
Comma-separated list of trusted users.
Comma-separated list of trusted groups.
User interface controls.
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 is True.
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 is False.
Print debugging information. True or False. Default is False.
The editor to use during a commit. Default is $EDITOR or
Encoding to try if it's not possible to decode the changelog
using UTF-8. Default is ISO-8859-1.
A file to read per-user ignore patterns from. This file should
be in the same format as a repository-wide .hgignore file. 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.
Allow to prompt the user. True or False. Default is True.
Template string for commands that print changesets.
The conflict resolution program to use during a manual merge.
There are some internal tools available:
keep the local version
use the other version
use the internal non-interactive merge tool
fail to merge
For more information on configuring merge tools see the merge-tools
command to use to apply patches. Look for gpatch or patch in
PATH if unset.
Reduce the amount of output printed. True or False. Default is
remote command to use for clone/push/pull operations. Default is
Warn if a .hg/hgrc file is ignored due to not being owned by a
trusted user or group. True or False. Default is True.
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 is False.
command to use for SSH connections. Default is ssh.
Require exact command names, instead of allowing unambiguous
abbreviations. True or False. Default is False.
Name of style to use for command output.
The timeout used when a lock is held (in seconds), a negative
value means no timeout. Default is 600.
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 is False.
The committer of a changeset created when running "commit".
Typically a person's name and email address, e.g. Fred Widget
<firstname.lastname@example.org>. Default is $EMAIL or username@hostname. If
the username in hgrc is empty, it has to be specified manually
or in a different hgrc file (e.g. $HOME/.hgrc, if the admin set
username = in the system hgrc).
Increase the amount of output printed. True or False. Default is
Web interface configuration.
Where to output the access log. Default is stdout.
Interface address to bind to. Default is all.
List of archive format (bz2, gz, zip) allowed for downloading.
Default is empty.
(DEPRECATED) Whether to allow .tar.bz2 downloading of repository
revisions. Default is False.
(DEPRECATED) Whether to allow .tar.gz downloading of repository
revisions. Default is False.
Whether to allow pulling from the repository. Default is True.
Whether to allow pushing to the repository. If empty or not set,
push 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 (separated by whitespace or
,). The contents of the allow_push list are examined after the
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
(separated by whitespace or ,), 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.
(DEPRECATED) Whether to allow .zip downloading of repository
revisions. Default is False. This feature creates temporary
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/.
Name or email address of the person in charge of the repository.
Defaults to ui.username or $EMAIL or "unknown" if unset or
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 (separated
by whitespace or ,) is also denied. The contents of the
deny_push list are examined before the allow_push list.
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 (separated by
whitespace or ,) 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
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).
Textual description of the repository's purpose or contents.
Default is "unknown".
Character encoding name. Example: "UTF-8"
Where to output the error log. Default is stderr.
Whether to hide the repository in the hgwebdir index. Default
Whether to use IPv6. Default is False.
Repository name to use in the web interface. Default is current
Maximum number of changes to list on the changelog. Default is
Maximum number of files to list per changeset. Default is 10.
Port to listen on. Default is 8000.
Prefix path to serve from. Default is '' (server root).
Whether to require that inbound pushes be transported over SSL
to prevent password sniffing. Default is True.
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.
How many lines a "zebra stripe" should span in multiline output.
Default is 1; set to 0 to disable.
Which template map style to use.
Where to find the HTML templates. Default is install path.
