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 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.

(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.


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
hooks

Commands that get automatically executed by various actions such as starting or finishing a commit. Multiple commands 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.

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.

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.

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.

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.

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.

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.

In earlier releases, the names of hook environment variables did not
have a "HG_" prefix.  These unprefixed names are still provided in
the environment for backwards compatibility, but their use is
deprecated, and they will be removed in a future release.
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.

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.

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".

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".

interactive

Allow to prompt the user. True or False. Default is True.

logtemplate

Template string for commands that print changesets.

style

Name of style to use for command output.

merge

The conflict resolution program to use during a manual merge. Default is "hgmerge".

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.

ssh

command to use for SSH connections. Default is ssh.

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, unless username is set to an empty string, which enforces specifying the username manually.

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.

allowbz2
