NAME
hgrc - configuration files for Mercurial
SYNOPSIS
The Mercurial system uses a set of configuration files to control
aspects of its behaviour.
FILES
Mercurial reads configuration data from several files, if they exist.
The names of these files depend on the system on which Mercurial is
installed.
(Unix) <install-root>/etc/mercurial/hgrc.d/*.rc, (Unix)
<install-root>/etc/mercurial/hgrc
Per-installation configuration files, searched for in the directory
where Mercurial is installed. For example, if installed in
/shared/tools, 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.
(Unix) /etc/mercurial/hgrc.d/*.rc, (Unix) /etc/mercurial/hgrc,
(Windows) C:\Mercurial\Mercurial.ini
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.
(Unix) $HOME/.hgrc, (Windows) C:\Documents and
Settings\USERNAME\Mercurial.ini, (Windows) $HOME\Mercurial.ini
Per-user configuration file, for the user running Mercurial.
Options in this file apply to all Mercurial commands executed by
any user in any directory. Options in this file override
per-installation and per-system options. On Windows system, one of
these is chosen exclusively according to definition of HOME
environment variable.
(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.
SYNTAX
A configuration file consists of sections, led by a "[section]" header
and followed by "name: value" entries; "name=value" is also accepted.
[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.
The optional values can contain format strings which refer to other
values in the same section, or values in a special DEFAULT section.
Lines beginning with "#" or ";" are ignored and may be used to provide
comments.
SECTIONS
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.
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".
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. In particular, if you are doing line ending
conversion on Windows using the popular dos2unix and unix2dos
programs, you *must* use the tempfile mechanism, as using pipes will
corrupt the contents of your files.
Tempfile example:
[encode]
# convert files to unix line ending conventions on checkin
**.txt = tempfile: dos2unix -n INFILE OUTFILE
[decode]
# convert files to windows line ending conventions when writing
# them to the working dir
**.txt = tempfile: unix2dos -n INFILE OUTFILE
defaults
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. They are all boolean and
defaults to False.
git
Use git extended diff format.
nodates
Don’t include dates in diff headers.
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.
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. Cannot be set interactively.
method
Optional. Method to use to send email messages. If value is
"smtp" (default), use SMTP (see section "[smtp]" 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.
Email example:
[email]
from = Joseph User <joe.user@example.com>
method = /usr/sbin/sendmail
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.
Example for ~/.hgrc:
[extensions]
# (the mq extension will get loaded from mercurial’s path)
hgext.mq =
# (this extension will get loaded from the file specified)
myfeature = ~/.hgext/myfeature.py
format
usestore
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.
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.
Example .hg/hgrc:
[hooks]
# do not use the site-wide hook
incoming =
incoming.email = /my/email/hook
incoming.autobuild = /my/build/hook
Most hooks are run with environment variables set that give added
useful information. For each hook below, the environment variables
it is passed are listed with names of the form "$HG_foo".
changegroup
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.
commit
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.
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. URL that was source of changes came
is in $HG_URL.
outgoing
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.
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. Hook failure is ignored.
pre-<command>
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
failure code.
prechangegroup
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.
precommit
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.
preoutgoing
Run before computing 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.
pretag
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 repo if $HG_LOCAL=0.
pretxnchangegroup
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.
pretxncommit
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.
preupdate
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.
tag
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 repo if $HG_LOCAL=0.
update
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 update succeeded, $HG_ERROR=0. If update
failed (e.g. because conflicts 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 (eg. tag) and not just the commit command.
Note2: Environment variables with empty values may not be passed to
hooks on platforms like Windows. For instance, $HG_PARENT2 will
not be available under Windows for non-merge changesets while being
set to an empty value under Unix-like systems.
The syntax for Python hooks is as follows:
hookname = python:modulename.submodule.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 failure of the hook.
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.
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: 25.
tls
Optional. Whether to connect to mail server using TLS. True or
False. Default: False.
username
Optional. User name to authenticate to SMTP server with. If
username is specified, password must also be specified.
Default: none.
password
Optional. Password to authenticate to SMTP server with. If
username is specified, password must also be specified.
Default: none.
local_hostname
Optional. It’s the hostname that the sender can use to identify
itself to the MTA.
paths
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 entries.
default
Directory or URL to use when pulling if no source is specified.
Default is set to repository from which the current repository
was cloned.
default-push
Optional. Directory or URL to use when pushing if no
destination is specified.
server
Controls generic server settings.
uncompressed
Whether to allow clients to clone a repo 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 (100Mbps 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 6Mbps), uncompressed streaming is slower, because of the
extra data transfer overhead. Default is False.
trusted
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 name "*".
users
Comma-separated list of trusted users.
groups
Comma-separated list of trusted groups.
ui
User interface controls.
debug
Print debugging information. True or False. Default is False.
editor
The editor to use during a commit. Default is $EDITOR or "vi".
fallbackencoding
Encoding to try if it’s not possible to decode the changelog
using UTF-8. Default is ISO-8859-1.
ignore
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.
interactive
Allow to prompt the user. True or False. Default is True.
logtemplate
Template string for commands that print changesets.
merge
The conflict resolution program to use during a manual merge.
Default is "hgmerge".
patch
command to use to apply patches. Look for gpatch or patch in
PATH if unset.
quiet
Reduce the amount of output printed. True or False. Default is
False.
remotecmd
remote command to use for clone/push/pull operations. Default
is hg.
report_untrusted
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.
slash
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.
ssh
command to use for SSH connections. Default is ssh.
strict
Require exact command names, instead of allowing unambiguous
abbreviations. True or False. Default is False.
style
Name of style to use for command output.
timeout
The timeout used when a lock is held (in seconds), a negative
value means no timeout. Default is 600.
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>". 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).
verbose
Increase the amount of output printed. True or False. Default
is False.
web
Web interface configuration.
accesslog
Where to output the access log. Default is stdout.
address
Interface address to bind to. Default is all.
allow_archive
List of archive format (bz2, gz, zip) allowed for downloading.
Default is empty.
allowbz2
(DEPRECATED) Whether to allow .tar.bz2 downloading of repo
revisions. Default is false.
allowgz
(DEPRECATED) Whether to allow .tar.gz downloading of repo
revisions. Default is false.
allowpull
Whether to allow pulling from the repository. Default is true.
allow_push
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 deny_push list.
allowzip
(DEPRECATED) Whether to allow .zip downloading of repo
revisions. Default is false. This feature creates temporary
files.
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/"
contact
Name or email address of the person in charge of the
repository. Default is "unknown".
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
(separated by whitespace or ",") is also denied. The contents
of the deny_push list are examined before the allow_push list.
description
Textual description of the repository’s purpose or contents.
Default is "unknown".
encoding
Character encoding name. Example: "UTF-8"
errorlog
Where to output the error log. Default is stderr.
hidden
Whether to hide the repository in the hgwebdir index. Default
is false.
ipv6
Whether to use IPv6. Default is false.
name
Repository name to use in the web interface. Default is current
working directory.
maxchanges
Maximum number of changes to list on the changelog. Default is
10.
maxfiles
Maximum number of files to list per changeset. Default is 10.
port
Port to listen on. Default is 8000.
push_ssl
Whether to require that inbound pushes be transported over SSL
to prevent password sniffing. Default is true.
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 multiline
output. Default is 1; set to 0 to disable.
style
Which template map style to use.
templates
Where to find the HTML templates. Default is install path.
