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

  changegroup;;

  commit;;

    Run after a changeset has been created in the local repository.

    Passed the ID of the newly created changeset in environment

    variable $NODE.  Parent changeset IDs in $P1 and $P2.

  incoming;;

    Run after a changeset has been pulled, pushed, or unbundled into

    the local repository.  Passed the ID of the newly arrived

    changeset in environment variable $NODE.

  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 in $P1 and $P2.

  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 in $NODE.  Name of tag in $TAG.  Tag is local if

    $LOCAL=1, in repo if $LOCAL=0.

  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 in $NODE.  Parent changeset IDs

    in $P1 and $P2.

  tag;;

    Run after a tag is created.  ID of tagged changeset in $NODE.

    Name of tag in $TAG.  Tag is local if $LOCAL=1, in repo if

    $LOCAL=0.

  proxy.

  host;;

    the proxy.

  passwd;;

    Optional.  Password to authenticate with at the proxy server.

  user;;
