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. *.rc files from a single directory are read in
alphabetical order, later ones overriding earlier ones. Where
multiple paths are given below, settings from later paths override
earlier ones.

(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. <install-root> is the
    parent directory of the hg executable (or symlink) being run.
    For example, if installed in /shared/tools/bin/hg, 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::
    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.

(Windows) <install-dir>\Mercurial.ini::
  or else::
(Windows) HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial::
  or else::
(Windows) C:\Mercurial\Mercurial.ini::
    Per-installation/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.
    Registry keys contain PATH-like strings, every part of which must
    reference a Mercurial.ini file or be a directory where *.rc files
    will be read.

(Unix) $HOME/.hgrc::
(Windows) %HOME%\Mercurial.ini::
(Windows) %HOME%\.hgrc::
(Windows) %USERPROFILE%\Mercurial.ini::
(Windows) %USERPROFILE%\.hgrc::
    Per-user configuration file(s), for the user running Mercurial.
    On Windows 9x, %HOME% is replaced by %APPDATA%.
    Options in these files apply to all Mercurial commands executed
    by this user in any directory. Options in thes files 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.
    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

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.

[[alias]]
alias::
 Defines command aliases.
  Aliases allow you to define your own commands in terms of other

changesets. You can define subsequent aliases using earlier ones:
+
    stable5 = latest -b stable
+
*Note*: It is possible to create aliases with the same names as
existing commands, which will then override the original
definitions. This is almost always a bad idea!

[[auth]]
auth::
  Authentication credentials for HTTP authentication.
  Each line has the following format:

    <name>.<argument> = <value>

  where <name> is used to group arguments into authentication
  entries.
  Example:

    foo.prefix = hg.intevation.org/mercurial
    foo.username = foo
    foo.password = bar

  prefix;;
    Either '*' or a URI prefix with or without the scheme part. The
    authentication entry with the longest matching prefix is used
    (where '*' matches everything and counts as a match of length 1).
    If the prefix doesn't include a scheme, the match is performed against
    the URI with its scheme stripped as well, and the schemes argument,
    q.v., is then subsequently consulted.
  username;;
    Username to authenticate with.
  password;;
    Optional. Password to authenticate with. If not given the user will be
    prompted for it.
  schemes;;
    Optional. Space separated list of URI schemes to use this authentication
    entry with. Only used if the prefix doesn't include a scheme. Supported
    schemes are http and https. They will match static-http and static-https
    respectively, as well.
    Default: https.

  If no suitable authentication entry is found, the user is
  prompted for credentials as usual if required by the remote.

[[decode]]
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:

    [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 and may corrupt the contents of your files.

  The most common usage is for LF <-> CRLF translation on Windows.
  For this, use the "smart" convertors which check for binary
  files:

    [extensions]
    hgext.win32text =
    [encode]
    ** = cleverencode:

[[defaults]]
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]]
diff::
  Settings used when displaying diffs. They are all boolean and
  defaults to False.

    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.
  charsets;;
    Optional. Comma-separated list of charsets considered
    convenient for recipients. Addresses, headers, and parts not
    containing patches of outgoing messages will be encoded in
    the first charset to which conversion from local encoding
    ($HGENCODING, ui.fallbackencoding) succeeds. If correct
    conversion fails, the text in question is sent as is.
    Defaults to empty (explicit) list.

  Order of outgoing email charsets:
 
    us-ascii             always first, regardless of settings
    email.charsets       in order given by user

[[extensions]]
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.

  To explicitly disable an extension that is enabled in an hgrc of
  broader scope, prepend its path with '!', as in
  'hgext.foo = !/ext/path' or 'hgext.foo = !' when path is not
  supplied.

    repositories will be compatible with Mercurial before version 0.9.4.

  usefncache;;
    Enable or disable the "fncache" repository format which enhances
    the "store" repository format (which has to be enabled to use
    fncache) to allow longer filenames and avoids using Windows reserved
    names, e.g. "nul". Enabled by default. Disabling this option ensures
    that the on-disk format of newly created repositories will be
    compatible with Mercurial before version 1.1.

[[merge-patterns]]
merge-patterns::
  This section specifies merge tools to associate with particular file
  patterns. Tools matched here will take precedence over the default
  merge tool. Patterns are globs by default, rooted at the repository root.

  Example:

    [merge-patterns]
    **.c = kdiff3

    Default: 0.
  executable;;
    Either just the name of the executable or its pathname.
    Default: the tool name.
  args;;
    The arguments to pass to the tool executable. You can refer to the files
    being merged as well as the output file through these variables: $base,
    $local, $other, $output.
    Default: $local $base $other
  premerge;;
    Attempt to run internal non-interactive 3-way merge tool before
    launching external tool.
    Default: True

    Attempt to fix up EOL changes caused by the merge tool.
    Default: False
  gui;;
    This tool requires a graphical interface to run. Default: False
  regkey;;
    Windows registry key which describes install location of this tool.
    Mercurial will search for this key first under HKEY_CURRENT_USER and
    then under HKEY_LOCAL_MACHINE. Default: None
  regname;;
    Name of value to read from specified registry key. Defaults to the
    unnamed (default) value.
  regappend;;
    String to append to the value read from the registry, typically the
    executable name of the tool. Default: None

[[hooks]]
hooks::
  Commands or Python functions that get automatically executed by
  various actions such as starting or finishing a commit. Multiple

  Most hooks are run with environment variables set that give useful
  additional 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;;

    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 collecting 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

    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 the update succeeded, $HG_ERROR=0. If the
    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 (e.g. tag) and
  not just the commit command.

  Note2: Environment variables with empty values may not be
  passed to hooks on platforms such as Windows. As an
  example, $HG_PARENT2 will have an empty value under
  Unix-like platforms for non-merge changesets, while it
  will not be available at all under Windows.

  The syntax for Python hooks is as follows:

    hookname = python:modulename.submodule.callable
    hookname = python:/path/to/python/module.py: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 a failure.

[[http_proxy]]
http_proxy::
  Used to access web-based Mercurial repositories through a HTTP
  proxy.

    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]]
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.

[[profiling]]
profiling::
  Specifies profiling format and file output.
  In this section description, 'profiling data' stands for the raw data
  collected during profiling, while 'profiling report' stands for a
  statistical text report generated from the profiling data.
  The profiling is done using lsprof.
  format;;
    Profiling format.
    Default: text.
    text;;
      Generate a profiling report.
      When saving to a file, it should be noted that only the report is saved,
      and the profiling data is not kept.
    kcachegrind;;
      Format profiling data for kcachegrind use:
      when saving to a file, the generated file can directly be loaded
      into kcachegrind.
  output;;
    File path where profiling data or report should be saved.
    If the file exists, it is replaced.
    Default: None, data is printed on stderr

[[server]]
server::
  Controls generic server settings.
  uncompressed;;

    6Mbps), uncompressed streaming is slower, because of the extra
    data transfer overhead. Default is False.

[[trusted]]
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]]
ui::
  User interface controls.
  archivemeta;;
    Whether to include the .hg_archival.txt file containing metadata
    (hashes for the repository base and for tip) in archives created by
    the hg archive command or downloaded via hgweb.
    Default is true.
  askusername;;
    Whether to prompt for a username when committing. If True, and
    neither $HGUSER nor $EMAIL has been specified, then the user will
    be prompted to enter a username.  If no username is entered, the
    default USER@HOST is used instead.
    Default is False.
  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;;

    For more information on configuring merge tools see the
    merge-tools section.

  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

    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
    <[e-mail]>". 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]]

    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.
  allow_read;;
    If the user has not already been denied repository access due to the
    contents of deny_read, this list determines whether to grant repository
    access to the user. If this list is not empty, and the user is
    unauthenticated or not present in the list (separated by whitespace or ","),
    then access is denied for the user.  If the list is empty or not set, then
    access is permitted to all users by default.  Setting allow_read to the
    special value "*" is equivalent to it not being set (i.e. access is
    permitted to all users).  The contents of the allow_read list are examined
    after the deny_read 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.
    Defaults to ui.username or $EMAIL or "unknown" if unset or empty.
  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.
  deny_read;;
    Whether to deny reading/viewing of the repository.  If this list is not
    empty, unauthenticated users are all denied, and any authenticated user name
    present in this list (separated by whitespace or ",") is also denied access
    to the repository.  If set to the special value "*", all remote users are
    denied access (rarely needed ;).  If deny_read is empty or not set, the
    determination of repository access depends on the presence and content of
    the allow_read list (see description).  If both deny_read and allow_read are
    empty or not set, then access is permitted to all users by default.  If the
    repository is being served via hgwebdir, denied users will not be able to
    see it in the list of repositories.  The contents of the deny_read list have
    priority over (are examined before) the contents of the allow_read 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.

    Prefix path to serve from. Default is '' (server root).
  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;;

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. *.rc files from a single directory are read in alphabetical
order, later ones overriding earlier ones. Where multiple paths are
given below, settings from later paths override earlier ones.

(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. <install-root> is the
    parent directory of the hg executable (or symlink) being run. For
    example, if installed in /shared/tools/bin/hg, 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::
    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.

(Windows) <install-dir>\Mercurial.ini::
  or else::
(Windows) HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial::
  or else::
(Windows) C:\Mercurial\Mercurial.ini::
    Per-installation/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. Registry
    keys contain PATH-like strings, every part of which must reference
    a Mercurial.ini file or be a directory where *.rc files will be

(Unix) $HOME/.hgrc::
(Windows) %HOME%\Mercurial.ini::
(Windows) %HOME%\.hgrc::
(Windows) %USERPROFILE%\Mercurial.ini::
(Windows) %USERPROFILE%\.hgrc::
    Per-user configuration file(s), for the user running Mercurial. On
    Windows 9x, %HOME% is replaced by %APPDATA%.
    Options in these files apply to all Mercurial commands executed by
    this user in any directory. Options in thes files 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. 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

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.

[[alias]]
alias::
 Defines command aliases.
  Aliases allow you to define your own commands in terms of other

changesets. You can define subsequent aliases using earlier ones:
+
    stable5 = latest -b stable
+
*Note*: It is possible to create aliases with the same names as
existing commands, which will then override the original definitions.
This is almost always a bad idea!

[[auth]]
auth::
  Authentication credentials for HTTP authentication. Each line has
  the following format:

    <name>.<argument> = <value>

  where <name> is used to group arguments into authentication entries.
  Example:

    foo.prefix = hg.intevation.org/mercurial
    foo.username = foo
    foo.password = bar

  prefix;;
    Either '*' or a URI prefix with or without the scheme part. The
    authentication entry with the longest matching prefix is used
    (where '*' matches everything and counts as a match of length 1).
    If the prefix doesn't include a scheme, the match is performed
    against the URI with its scheme stripped as well, and the schemes
    argument, q.v., is then subsequently consulted.
  username;;
    Username to authenticate with.
  password;;
    Optional. Password to authenticate with. If not given the user
    will be prompted for it.
  schemes;;
    Optional. Space separated list of URI schemes to use this
    authentication entry with. Only used if the prefix doesn't include
    a scheme. Supported schemes are http and https. They will match
    static-http and static-https respectively, as well.
    Default: https.

  If no suitable authentication entry is found, the user is prompted
  for credentials as usual if required by the remote.

[[decode]]
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:

    [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 and may corrupt the contents of your files.

  The most common usage is for LF <-> CRLF translation on Windows. For
  this, use the "smart" convertors which check for binary files:

    [extensions]
    hgext.win32text =
    [encode]
    ** = cleverencode:

[[defaults]]
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]]
diff::
  Settings used when displaying diffs. They are all boolean and
  defaults to False.

    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.
  charsets;;
    Optional. Comma-separated list of charsets considered convenient
    for recipients. Addresses, headers, and parts not containing
    patches of outgoing messages will be encoded in the first charset
    to which conversion from local encoding ($HGENCODING,
    ui.fallbackencoding) succeeds. If correct conversion fails, the
    text in question is sent as is. Defaults to empty (explicit) list.

  Order of outgoing email charsets:
 
    us-ascii             always first, regardless of settings
    email.charsets       in order given by user

[[extensions]]
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.

  To explicitly disable an extension that is enabled in an hgrc of
  broader scope, prepend its path with '!', as in
  'hgext.foo = !/ext/path' or 'hgext.foo = !' when path is not
  supplied.

    repositories will be compatible with Mercurial before version 0.9.4.

  usefncache;;
    Enable or disable the "fncache" repository format which enhances
    the "store" repository format (which has to be enabled to use
    fncache) to allow longer filenames and avoids using Windows
    reserved names, e.g. "nul". Enabled by default. Disabling this
    option ensures that the on-disk format of newly created
    repositories will be compatible with Mercurial before version 1.1.

[[merge-patterns]]
merge-patterns::
  This section specifies merge tools to associate with particular file
  patterns. Tools matched here will take precedence over the default
  merge tool. Patterns are globs by default, rooted at the repository
  root.

  Example:

    [merge-patterns]
    **.c = kdiff3

    Default: 0.
  executable;;
    Either just the name of the executable or its pathname.
    Default: the tool name.
  args;;
    The arguments to pass to the tool executable. You can refer to the
    files being merged as well as the output file through these
    variables: $base, $local, $other, $output.
    Default: $local $base $other
  premerge;;
    Attempt to run internal non-interactive 3-way merge tool before
    launching external tool.
    Default: True

    Attempt to fix up EOL changes caused by the merge tool.
    Default: False
  gui;;
    This tool requires a graphical interface to run. Default: False
  regkey;;
    Windows registry key which describes install location of this
    tool. Mercurial will search for this key first under
    HKEY_CURRENT_USER and then under HKEY_LOCAL_MACHINE.
    Default: None
  regname;;
    Name of value to read from specified registry key. Defaults to the
    unnamed (default) value.
  regappend;;
    String to append to the value read from the registry, typically
    the executable name of the tool.
    Default: None

[[hooks]]
hooks::
  Commands or Python functions that get automatically executed by
  various actions such as starting or finishing a commit. Multiple

  Most hooks are run with environment variables set that give useful
  additional 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;;

    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 collecting 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

    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 the update succeeded, $HG_ERROR=0. If the
    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 (e.g. tag) and not just the commit command.

  Note2: Environment variables with empty values may not be passed to
  hooks on platforms such as Windows. As an example, $HG_PARENT2 will
  have an empty value under Unix-like platforms for non-merge
  changesets, while it will not be available at all under Windows.

  The syntax for Python hooks is as follows:

    hookname = python:modulename.submodule.callable
    hookname = python:/path/to/python/module.py: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 a failure.

[[http_proxy]]
http_proxy::
  Used to access web-based Mercurial repositories through a HTTP
  proxy.

    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]]
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.

[[profiling]]
profiling::
  Specifies profiling format and file output. In this section
  description, 'profiling data' stands for the raw data collected
  during profiling, while 'profiling report' stands for a statistical
  text report generated from the profiling data. The profiling is done
  using lsprof.
  format;;
    Profiling format.
    Default: text.
    text;;
      Generate a profiling report. When saving to a file, it should be
      noted that only the report is saved, and the profiling data is
      not kept.
    kcachegrind;;
      Format profiling data for kcachegrind use: when saving to a
      file, the generated file can directly be loaded into
      kcachegrind.
  output;;
    File path where profiling data or report should be saved. If the
    file exists, it is replaced. Default: None, data is printed on
    stderr

[[server]]
server::
  Controls generic server settings.
  uncompressed;;

    6Mbps), uncompressed streaming is slower, because of the extra
    data transfer overhead. Default is False.

[[trusted]]
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]]
ui::
  User interface controls.
  archivemeta;;
    Whether to include the .hg_archival.txt file containing metadata
    (hashes for the repository base and for tip) in archives created
    by the hg archive command or downloaded via hgweb.
    Default is true.
  askusername;;
    Whether to prompt for a username when committing. If True, and
    neither $HGUSER nor $EMAIL has been specified, then the user will
    be prompted to enter a username. If no username is entered, the
    default USER@HOST is used instead.
    Default is False.
  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;;

    For more information on configuring merge tools see the
    merge-tools section.

  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

    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
    <[e-mail]>". 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]]

    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.
  allow_read;;
    If the user has not already been denied repository access due to
    the contents of deny_read, this list determines whether to grant
    repository access to the user. If this list is not empty, and the
    user is unauthenticated or not present in the list (separated by
    whitespace or ","), then access is denied for the user. If the
    list is empty or not set, then access is permitted to all users by
    default. Setting allow_read to the special value "*" is equivalent
    to it not being set (i.e. access is permitted to all users). The
    contents of the allow_read list are examined after the deny_read
    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.
    Defaults to ui.username or $EMAIL or "unknown" if unset or empty.
  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.
  deny_read;;
    Whether to deny reading/viewing of the repository. If this list is
    not empty, unauthenticated users are all denied, and any
    authenticated user name present in this list (separated by
    whitespace or ",") is also denied access to the repository. If set
    to the special value "*", all remote users are denied access
    (rarely needed ;). If deny_read is empty or not set, the
    determination of repository access depends on the presence and
    content of the allow_read list (see description). If both
    deny_read and allow_read are empty or not set, then access is
    permitted to all users by default. If the repository is being
    served via hgwebdir, denied users will not be able to see it in
    the list of repositories. The contents of the deny_read list have
    priority over (are examined before) the contents of the allow_read
    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.

    Prefix path to serve from. Default is '' (server root).
  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;;
