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 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.
  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.

  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.

  A Python hook must return a "true" value to succeed.  Returning a
  "false" value or raising an exception 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.

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.

    Whether to allow .tar.gz downloading of repo revisions. Default is false.
  allowpull;;
    Whether to allow pulling from the repository. Default is true.
  allowzip;;
    Whether to allow .zip downloading of repo revisions. Default is false.
    This feature creates temporary files.
