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.
