HGRC(5) Mercurial Manual HGRC(5)NAMEhgrc - configuration files for Mercurial
DESCRIPTION
The Mercurial system uses a set of configuration files to control
aspects of its behavior.
The configuration files use a simple ini-file format. A configuration
file consists of sections, led by a [section] header and followed by
name = value entries:
[ui]
username = Firstname Lastname <firstname.lastname@example.net>
verbose = True
The above entries will be referred to as ui.username and ui.verbose,
respectively. See the Syntax section below.
FILES
Mercurial reads configuration data from several files, if they exist.
These files do not exist by default and you will have to create the
appropriate configuration files yourself: global configuration like the
username setting is typically put into %USERPROFILE%\mercurial.ini or
$HOME/.hgrc and local configuration is put into the per-repository
<repo>/.hg/hgrc file.
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 earlier paths override later ones.
(All) <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 over‐
ride options in all other configuration files. On Plan 9 and 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.
(Plan 9) $home/lib/hgrc
(Unix) $HOME/.hgrc
(Windows) %USERPROFILE%\.hgrc
(Windows) %USERPROFILE%\Mercurial.ini
(Windows) %HOME%\.hgrc
(Windows) %HOME%\Mercurial.ini
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 direc‐
tory. Options in these files override per-system and per-installa‐
tion options.
(Plan 9) /lib/mercurial/hgrc
(Plan 9) /lib/mercurial/hgrc.d/*.rc
(Unix) /etc/mercurial/hgrc
(Unix) /etc/mercurial/hgrc.d/*.rc
Per-system configuration files, for the system on which Mercurial is
running. Options in these files apply to all Mercurial commands exe‐
cuted by any user in any directory. Options in these files override
per-installation options.
(Plan 9) <install-root>/lib/mercurial/hgrc
(Plan 9) <install-root>/lib/mercurial/hgrc.d/*.rc
(Unix) <install-root>/etc/mercurial/hgrc
(Unix) <install-root>/etc/mercurial/hgrc.d/*.rc
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.
(Windows) <install-dir>\Mercurial.ini or
(Windows) <install-dir>\hgrc.d\*.rc or
(Windows) HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial
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 con‐
tain PATH-like strings, every part of which must reference a Mercu‐
rial.ini file or be a directory where *.rc files will be read. Mer‐
curial checks each of these locations in the specified order until
one or more configuration files are detected.
Note The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mercu‐
rial is used when running 32-bit Python on 64-bit Windows.
SYNTAX
A configuration file consists of sections, led by a [section] header
and followed by name = value entries (sometimes called configuration
keys):
[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. Lines beginning with # or
; are ignored and may be used to provide comments.
Configuration keys can be set multiple times, in which case Mercurial
will use the value that was configured last. As an example:
[spam]
eggs=large
ham=serrano
eggs=small
This would set the configuration key named eggs to small.
It is also possible to define a section multiple times. A section can
be redefined on the same and/or on different configuration files. For
example:
[foo]
eggs=large
ham=serrano
eggs=small
[bar]
eggs=ham
green=
eggs
[foo]
ham=prosciutto
eggs=medium
bread=toasted
This would set the eggs, ham, and bread configuration keys of the foo
section to medium, prosciutto, and toasted, respectively. As you can
see there only thing that matters is the last value that was set for
each of the configuration keys.
If a configuration key is set multiple times in different configuration
files the final value will depend on the order in which the different
configuration files are read, with settings from earlier paths overrid‐
ing later ones as described on the Files section above.
A line of the form %include file will include file into the current
configuration file. The inclusion is recursive, which means that
included files can include other files. Filenames are relative to the
configuration file in which the %include directive is found. Environ‐
ment variables and ~user constructs are expanded in file. This lets you
do something like:
%include ~/.hgrc.d/$HOST.rc
to include a different configuration file on each computer you use.
A line with %unset name will remove name from the current section, if
it has been set previously.
The values are either free-form text strings, lists of text strings, or
Boolean values. Boolean values can be set to true using any of "1",
"yes", "true", or "on" and to false using "0", "no", "false", or "off"
(all case insensitive).
List values are separated by whitespace or comma, except when values
are placed in double quotation marks:
allow_read = "John Doe, PhD", brian, betty
Quotation marks can be escaped by prefixing them with a backslash. Only
quotation marks at the beginning of a word is counted as a quotation
(e.g., foo"bar baz is the list of foo"bar and baz).
SECTIONS
This section describes the different sections that may appear in a Mer‐
curial configuration file, the purpose of each section, its possible
keys, and their possible values.
alias
Defines command aliases. Aliases allow you to define your own commands
in terms of other commands (or aliases), optionally including argu‐
ments. Positional arguments in the form of $1, $2, etc in the alias
definition are expanded by Mercurial before execution. Positional argu‐
ments not already used by $N in the definition are put at the end of
the command to be executed.
Alias definitions consist of lines of the form:
<alias> = <command> [<argument>]...
For example, this definition:
latest = log --limit 5
creates a new command latest that shows only the five most recent
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!
An alias can start with an exclamation point (!) to make it a shell
alias. A shell alias is executed with the shell and will let you run
arbitrary commands. As an example,
echo = !echo $@
will let you do hg echo foo to have foo printed in your terminal. A
better example might be:
purge = !$HG status --no-status --unknown -0 | xargs -0 rm
which will make hg purge delete all unknown files in the repository in
the same manner as the purge extension.
Positional arguments like $1, $2, etc. in the alias definition expand
to the command arguments. Unmatched arguments are removed. $0 expands
to the alias name and $@ expands to all arguments separated by a space.
These expansions happen before the command is passed to the shell.
Shell aliases are executed in an environment where $HG expands to the
path of the Mercurial that was used to execute the alias. This is use‐
ful when you want to call further Mercurial commands in a shell alias,
as was done above for the purge alias. In addition, $HG_ARGS expands to
the arguments given to Mercurial. In the hg echo foo call above,
$HG_ARGS would expand to echo foo.
Note Some global configuration options such as -R are processed
before shell aliases and will thus not be passed to aliases.
annotate
Settings used when displaying file annotations. All values are Booleans
and default to False. See diff section for related options for the diff
command.
ignorews
Ignore white space when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
auth
Authentication credentials for HTTP authentication. This section allows
you to store usernames and passwords for use when logging into HTTP
servers. See the [web] configuration section if you want to configure
who can login to your HTTP server.
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
foo.schemes = http https
bar.prefix = secure.example.org
bar.key = path/to/file.key
bar.cert = path/to/file.cert
bar.schemes = https
Supported arguments:
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
Optional. Username to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it. Environment variables are expanded in
the username letting you do foo.username = $USER. If the URI
includes a username, only [auth] entries with a matching user‐
name or without a username will be considered.
password
Optional. Password to authenticate with. If not given, and the
remote site requires basic or digest authentication, the user
will be prompted for it.
key
Optional. PEM encoded client certificate key file. Environment
variables are expanded in the filename.
cert
Optional. PEM encoded client certificate chain file. Environment
variables are expanded in the filename.
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/encode
Filters for transforming files on checkout/checkin. This would typi‐
cally be used for newline processing or other localization/canonical‐
ization of files.
Filters consist of a filter pattern followed by a filter command. Fil‐
ter 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. For each file only the first match‐
ing filter applies.
The filter command can start with a specifier, either pipe: or temp‐
file:. 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 and may corrupt the contents of your files.
This filter mechanism is used internally by the eol extension to trans‐
late line ending characters between Windows (CRLF) and Unix (LF) for‐
mat. We suggest you use the eol extension for convenience.
defaults
(defaults are deprecated. Don't use them. Use aliases instead)
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 defin‐
ing command defaults. The command defaults will also be applied to the
aliases of the commands defined.
diff
Settings used when displaying diffs. Everything except for unified is a
Boolean and defaults to False. See annotate section for related options
for the annotate command.
git
Use git extended diff format.
nodates
Don't include dates in diff headers.
showfunc
Show which function each change is in.
ignorews
Ignore white space when comparing lines.
ignorewsamount
Ignore changes in the amount of white space.
ignoreblanklines
Ignore changes whose lines are all blank.
unified
Number of lines of context to show.
email
Settings for extensions that send email messages.
from
Optional. Email address to use in "From" header and SMTP enve‐
lope of outgoing messages.
to
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.
method
Optional. Method to use to send email messages. If value is smtp
(default), use SMTP (see the [smtp] section 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 character sets considered con‐
venient for recipients. Addresses, headers, and parts not con‐
taining patches of outgoing messages will be encoded in the
first character set to which conversion from local encoding
($HGENCODING, ui.fallbackencoding) succeeds. If correct conver‐
sion fails, the text in question is sent as is. Defaults to
empty (explicit) list.
Order of outgoing email character sets:
1. us-ascii: always first, regardless of settings
2. email.charsets: in order given by user
3. ui.fallbackencoding: if not in email.charsets
4. $HGENCODING: if not in email.charsets
5. utf-8: always last, regardless of settings
Email example:
[email]
from = Joseph User <joe.user@example.com>
method = /usr/sbin/sendmail
# charsets for western Europeans
# us-ascii, utf-8 omitted, as they are tried first and last
charsets = iso-8859-1, iso-8859-15, windows-1252
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 foo = !/ext/path or foo =
! when path is not supplied.
Example for ~/.hgrc:
[extensions]
# (the mq extension will get loaded from Mercurial's path)
mq =
# (this extension will get loaded from the file specified)
myfeature = ~/.hgext/myfeature.py
format
usestore
Enable or disable the "store" repository format which improves
compatibility with systems that fold case or otherwise mangle
filenames. Enabled by default. Disabling this option will allow
you to store longer filenames in some situations at the expense
of compatibility and ensures that the on-disk format of newly
created 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 reposi‐
tories will be compatible with Mercurial before version 1.1.
dotencode
Enable or disable the "dotencode" repository format which
enhances the "fncache" repository format (which has to be
enabled to use dotencode) to avoid issues with filenames start‐
ing with ._ on Mac OS X and spaces on Windows. Enabled by
default. Disabling this option ensures that the on-disk format
of newly created repositories will be compatible with Mercurial
before version 1.7.
graph
Web graph view configuration. This section let you change graph ele‐
ments display properties by branches, for instance to make the default
branch stand out.
Each line has the following format:
<branch>.<argument> = <value>
where <branch> is the name of the branch being customized. Example:
[graph]
# 2px width
default.width = 2
# red color
default.color = FF0000
Supported arguments:
width
Set branch edges width in pixels.
color
Set branch edges color in hexadecimal RGB notation.
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. Hooks can be prioritized by adding a prefix of priority
to the hook name on a new line and setting the priority. The default
priority is 0 if not specified.
Example .hg/hgrc:
[hooks]
# update working directory after adding changesets
changegroup.update = hg update
# do not use the site-wide hook
incoming =
incoming.email = /my/email/hook
incoming.autobuild = /my/build/hook
# force autobuild hook to run before other incoming hooks
priority.incoming.autobuild = 1
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 unbun‐
dle. 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 change‐
set 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
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.
post-<command>
Run after successful invocations of the associated command. The
contents of the command line are passed as $HG_ARGS and the
result code in $HG_RESULT. Parsed command line arguments are
passed as $HG_PATS and $HG_OPTS. These contain string represen‐
tations of the python data internally passed to <command>.
$HG_OPTS is a dictionary of options (with unspecified options
set to their defaults). $HG_PATS is a list of arguments. Hook
failure is ignored.
pre-<command>
Run before executing the associated command. The contents of the
command line are passed as $HG_ARGS. Parsed command line argu‐
ments are passed as $HG_PATS and $HG_OPTS. These contain string
representations of the data internally passed to <command>.
$HG_OPTS is a dictionary of options (with unspecified options
set to their defaults). $HG_PATS is a list of arguments. 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.
prelistkeys
Run before listing pushkeys (like bookmarks) in the repository.
Non-zero status will cause failure. The key namespace is in
$HG_NAMESPACE.
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.
prepushkey
Run before a pushkey (like a bookmark) is added to the reposi‐
tory. Non-zero status will cause the key to be rejected. The key
namespace is in $HG_NAMESPACE, the key is in $HG_KEY, the old
value (if any) is in $HG_OLD, and the new value is in $HG_NEW.
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 repository if $HG_LOCAL=0.
pretxnchangegroup
Run after a changegroup has been added via push, pull or unbun‐
dle, 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 transac‐
tion to be rolled back. ID of changeset is in $HG_NODE. Parent
changeset IDs are in $HG_PARENT1 and $HG_PARENT2.
preupdate
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.
listkeys
Run after listing pushkeys (like bookmarks) in the repository.
The key namespace is in $HG_NAMESPACE. $HG_VALUES is a dictio‐
nary containing the keys and values.
pushkey
Run after a pushkey (like a bookmark) is added to the reposi‐
tory. The key namespace is in $HG_NAMESPACE, the key is in
$HG_KEY, the old value (if any) is in $HG_OLD, and the new value
is in $HG_NEW.
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 repository 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 transac‐
tions. Also, hooks like "commit" will be called in all contexts
that generate a commit (e.g. tag) and not just the commit com‐
mand.
Note 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.
hostfingerprints
Fingerprints of the certificates of known HTTPS servers. A HTTPS con‐
nection to a server with a fingerprint configured here will only suc‐
ceed if the servers certificate matches the fingerprint. This is very
similar to how ssh known hosts works. The fingerprint is the SHA-1
hash value of the DER encoded certificate. The CA chain and web.cac‐
erts is not used for servers with a fingerprint.
For example:
[hostfingerprints]
hg.intevation.org = 44:ed:af:1f:97:11:b6:01:7a:48:45:fc:10:3c:b7:f9:d4:89:2a:9d
This feature is only supported when using Python 2.6 or later.
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.
always
Optional. Always use the proxy, even for localhost and any
entries in http_proxy.no. True or False. Default: False.
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
**.jpg = myimgmerge
merge-tools
This section configures external merge tools to use for file-level
merges.
Example ~/.hgrc:
[merge-tools]
# Override stock tool location
kdiff3.executable = ~/bin/kdiff3
# Specify command line
kdiff3.args = $base $local $other -o $output
# Give higher priority
kdiff3.priority = 1
# Define new tool
myHtmlTool.args = -m $local $other $base $output
myHtmlTool.regkey = Software\FooSoftware\HtmlMerge
myHtmlTool.priority = 1
Supported arguments:
priority
The priority in which to evaluate this tool. Default: 0.
executable
Either just the name of the executable or its pathname. On Win‐
dows, the path can use environment variables with ${Program‐
Files} syntax. 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. Options are true, false, or keep to
leave markers in the file if the premerge fails. Default: True
binary
This tool can merge binary files. Defaults to False, unless tool
was selected by file pattern match.
symlink
This tool can merge symlinks. Defaults to False, even if tool
was selected by file pattern match.
check
A list of merge success-checking options:
changed
Ask whether merge was successful when the merged file
shows no changes.
conflicts
Check whether there are conflicts even though the tool
reported success.
prompt
Always prompt for merge success, regardless of success
reported by tool.
fixeol
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_CUR‐
RENT_USER and then under HKEY_LOCAL_MACHINE. Default: None
regkeyalt
An alternate Windows registry key to try if the first key is not
found. The alternate key uses the same regname and regappend
semantics of the primary key. The most common use for this key
is to search for 32bit applications on 64bit operating systems.
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
patch
Settings used when applying patches, for instance through the 'import'
command or with Mercurial Queues extension.
eol
When set to 'strict' patch content and patched files end of
lines are preserved. When set to lf or crlf, both files end of
lines are ignored when patching and the result line endings are
normalized to either LF (Unix) or CRLF (Windows). When set to
auto, end of lines are again ignored while patching but line
endings in patched files are normalized to their original set‐
ting on a per-file basis. If target file does not exist or has
no end of line, patch line endings are preserved. Default:
strict.
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.
Custom paths can be defined by assigning the path to a name that later
can be used from the command line. Example:
[paths]
my_path = http://example.com/path
To push to the path defined in my_path run the command:
hg push my_path
phases
Specifies default handling of phases. See hg help phases for more
information about working with phases.
publish
Controls draft phase behavior when working as a server. When
true, pushed changesets are set to public in both client and
server and pulled or cloned changesets are set to public in the
client. Default: True
new-commit
Phase of newly-created commits. Default: draft
profiling
Specifies profiling type, format, and file output. Two profilers are
supported: an instrumenting profiler (named ls), and a sampling pro‐
filer (named stat).
In this section description, 'profiling data' stands for the raw data
collected during profiling, while 'profiling report' stands for a sta‐
tistical text report generated from the profiling data. The profiling
is done using lsprof.
type
The type of profiler to use. Default: ls.
ls
Use Python's built-in instrumenting profiler. This pro‐
filer works on all platforms, but each line number it
reports is the first line of a function. This restriction
makes it difficult to identify the expensive parts of a
non-trivial function.
stat
Use a third-party statistical profiler, statprof. This
profiler currently runs only on Unix systems, and is most
useful for profiling commands that run for longer than
about 0.1 seconds.
format
Profiling format. Specific to the ls instrumenting profiler.
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.
frequency
Sampling frequency. Specific to the stat sampling profiler.
Default: 1000.
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
sort
Sort field. Specific to the ls instrumenting profiler. One of
callcount, reccallcount, totaltime and inlinetime. Default:
inlinetime.
limit
Number of lines to show. Specific to the ls instrumenting pro‐
filer. Default: 30.
nested
Show at most this number of lines of drill-down info after each
main entry. This can help explain the difference between Total
and Inline. Specific to the ls instrumenting profiler.
Default: 5.
revsetalias
Alias definitions for revsets. See hg help revsets for details.
server
Controls generic server settings.
uncompressed
Whether to allow clients to clone a repository using the uncom‐
pressed streaming protocol. This transfers about 40% more data
than a regular clone, but uses less memory and CPU on both
server and client. Over a LAN (100 Mbps or better) or a very
fast WAN, an uncompressed streaming clone is a lot faster (~10x)
than a regular clone. Over most WAN connections (anything slower
than about 6 Mbps), uncompressed streaming is slower, because of
the extra data transfer overhead. This mode will also temporar‐
ily hold the write lock while determining what data to transfer.
Default is True.
preferuncompressed
When set, clients will try to use the uncompressed streaming
protocol. Default is False.
validate
Whether to validate the completeness of pushed changesets by
checking that all new file revisions specified in manifests are
present. Default is False.
smtp
Configuration for extensions that need to send email messages.
host
Host name of mail server, e.g. "mail.example.com".
port
Optional. Port to connect to on mail server. Default: 465 (if
tls is smtps) or 25 (otherwise).
tls
Optional. Method to enable TLS when connecting to mail server:
starttls, smtps or none. Default: none.
verifycert
Optional. Verification for the certificate of mail server, when
tls is starttls or smtps. "strict", "loose" or False. For
"strict" or "loose", the certificate is verified as same as the
verification for HTTPS connections (see [hostfingerprints] and
[web] cacerts also). For "strict", sending email is also
aborted, if there is no configuration for mail server in
[hostfingerprints] and [web] cacerts. --insecure for hg email
overwrites this as "loose". Default: "strict".
username
Optional. User name for authenticating with the SMTP server.
Default: none.
password
Optional. Password for authenticating with the SMTP server. If
not specified, interactive sessions will prompt the user for a
password; non-interactive sessions will fail. Default: none.
local_hostname
Optional. It's the hostname that the sender can use to identify
itself to the MTA.
subpaths
Subrepository source URLs can go stale if a remote server changes name
or becomes temporarily unavailable. This section lets you define re‐
write rules of the form:
<pattern> = <replacement>
where pattern is a regular expression matching a subrepository source
URL and replacement is the replacement string used to rewrite it.
Groups can be matched in pattern and referenced in replacements. For
instance:
http://server/(.*)-hg/ = http://hg.server/\1/
rewrites http://server/foo-hg/ into http://hg.server/foo/.
Relative subrepository paths are first made absolute, and the rewrite
rules are then applied on the full (absolute) path. The rules are
applied in definition order.
trusted
Mercurial will not use the settings in the .hg/hgrc file from a reposi‐
tory if it doesn't belong to a trusted user or to a trusted group, as
various hgrc features allow arbitrary commands to be run. This issue is
often encountered when configuring hooks or extensions for shared
repositories or servers. However, the web interface will use some safe
settings from the [web] section.
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 *. These settings must be placed in an already-trusted file to
take effect, such as $HOME/.hgrc of the user or service running Mercu‐
rial.
users
Comma-separated list of trusted users.
groups
Comma-separated list of trusted groups.
ui
User interface controls.
archivemeta
Whether to include the .hg_archival.txt file containing meta
data (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.
commitsubrepos
Whether to commit modified subrepositories when committing the
parent repository. If False and one subrepository has uncommit‐
ted changes, abort the commit. 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 for‐
mat, see the hgignore(5) man page.
interactive
Allow to prompt the user. True or False. Default is True.
logtemplate
Template string for commands that print changesets.
merge
The conflict resolution program to use during a manual merge.
For more information on merge tools see hg help merge-tools.
For configuring merge tools see the [merge-tools] section.
portablefilenames
Check for portable filenames. Can be warn, ignore or abort.
Default is warn. If set to warn (or true), a warning message is
printed on POSIX platforms, if a file with a non-portable file‐
name is added (e.g. a file with a name that can't be created on
Windows because it contains reserved parts like AUX, reserved
characters like :, or would cause a case collision with an
existing file). If set to ignore (or false), no warning is
printed. If set to abort, the command is aborted. On Windows,
this configuration option is ignored and the command aborted.
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.
reportoldssl
Warn if an SSL certificate is unable to be due to using Python
2.5 or earlier. True or False. Default is True.
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
abbreviations. True or False. Default is False.
style
Name of style to use for command output.
timeout
The timeout used when a lock is held (in seconds), a negative
value means no timeout. Default is 600.
traceback
Mercurial always prints a traceback when an unknown exception
occurs. Setting this to True will make Mercurial print a trace‐
back on all exceptions, even those recognized by Mercurial (such
as IOError or MemoryError). Default is False.
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. 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). Environment variables in the
username are expanded.
verbose
Increase the amount of output printed. True or False. Default is
False.
web
Web interface configuration. The settings in this section apply to both
the builtin webserver (started by hg serve) and the script you run
through a webserver (hgweb.cgi and the derivatives for FastCGI and
WSGI).
The Mercurial webserver does no authentication (it does not prompt for
usernames and passwords to validate who users are), but it does do
authorization (it grants or denies access for authenticated users based
on settings in this section). You must either configure your webserver
to do authentication for you, or disable the authorization checks.
For a quick setup in a trusted environment, e.g., a private LAN, where
you want it to accept pushes from anybody, you can use the following
command line:
$ hg --config web.allow_push=* --config web.push_ssl=False serve
Note that this will allow anybody to push anything to the server and
that this should not be used for public servers.
The full set of options is:
accesslog
Where to output the access log. Default is stdout.
address
Interface address to bind to. Default is all.
allow_archive
List of archive format (bz2, gz, zip) allowed for downloading.
Default is empty.
allowbz2
(DEPRECATED) Whether to allow .tar.bz2 downloading of repository
revisions. Default is False.
allowgz
(DEPRECATED) Whether to allow .tar.gz downloading of repository
revisions. 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. 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, 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 repository
revisions. Default is False. This feature creates temporary
files.
archivesubrepos
Whether to recurse into subrepositories when archiving. Default
is False.
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/.
cacerts
Path to file containing a list of PEM encoded certificate
authority certificates. Environment variables and ~user con‐
structs are expanded in the filename. If specified on the
client, then it will verify the identity of remote HTTPS servers
with these certificates.
This feature is only supported when using Python 2.6 or later.
If you wish to use it with earlier versions of Python, install
the backported version of the ssl library that is available from
http://pypi.python.org.
To disable SSL verification temporarily, specify --insecure from
command line.
You can use OpenSSL's CA certificate file if your platform has
one. On most Linux systems this will be /etc/ssl/certs/ca-cer‐
tificates.crt. Otherwise you will have to generate this file
manually. The form must be as follows:
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
... (certificate in base64 PEM encoding) ...
-----END CERTIFICATE-----
cache
Whether to support caching in hgweb. Defaults to True.
collapse
With descend enabled, repositories in subdirectories are shown
at a single level alongside repositories in the current path.
With collapse also enabled, repositories residing at a deeper
level than the current path are grouped behind navigable direc‐
tory entries that lead to the locations of these repositories.
In effect, this setting collapses each collection of reposito‐
ries found within a subdirectory into a single entry for that
subdirectory. Default is False.
comparisoncontext
Number of lines of context to show in side-by-side file compari‐
son. If negative or the value full, whole files are shown.
Default is 5. This setting can be overridden by a context
request parameter to the comparison command, taking the same
values.
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 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 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.
descend
hgwebdir indexes will not descend into subdirectories. Only
repositories directly in the current path will be shown (other
repositories are still available from the index corresponding to
their containing path).
description
Textual description of the repository's purpose or contents.
Default is "unknown".
encoding
Character encoding name. Default is the current locale charset.
Example: "UTF-8"
errorlog
Where to output the error log. Default is stderr.
guessmime
Control MIME types for raw download of file content. Set to
True to let hgweb guess the content type from the file exten‐
sion. This will serve HTML files as text/html and might allow
cross-site scripting attacks when serving untrusted reposito‐
ries. Default is False.
hidden
Whether to hide the repository in the hgwebdir index. Default
is False.
ipv6
Whether to use IPv6. Default is False.
logoimg
File name of the logo image that some templates display on each
page. The file name is relative to staticurl. That is, the full
path to the logo image is "staticurl/logoimg". If unset, hgl‐
ogo.png will be used.
logourl
Base URL to use for logos. If unset, http://mercu‐
rial.selenic.com/ will be used.
maxchanges
Maximum number of changes to list on the changelog. Default is
10.
maxfiles
Maximum number of files to list per changeset. Default is 10.
maxshortchanges
Maximum number of changes to list on the shortlog, graph or
filelog pages. Default is 60.
name
Repository name to use in the web interface. Default is current
working directory.
port
Port to listen on. Default is 8000.
prefix
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 multi-line out‐
put. Default is 1; set to 0 to disable.
style
Which template map style to use.
templates
Where to find the HTML templates. Default is install path.
websub
Web substitution filter definition. You can use this section to define
a set of regular expression substitution patterns which let you auto‐
matically modify the hgweb server output.
The default hgweb templates only apply these substitution patterns on
the revision description fields. You can apply them anywhere you want
when you create your own templates by adding calls to the "websub" fil‐
ter (usually after calling the "escape" filter).
This can be used, for example, to convert issue references to links to
your issue tracker, or to convert "markdown-like" syntax into HTML (see
the examples below).
Each entry in this section names a substitution filter. The value of
each entry defines the substitution expression itself. The websub
expressions follow the old interhg extension syntax, which in turn imi‐
tates the Unix sed replacement syntax:
patternname = s/SEARCH_REGEX/REPLACE_EXPRESSION/[i]
You can use any separator other than "/". The final "i" is optional and
indicates that the search must be case insensitive.
Examples:
[websub]
issues = s|issue(\d+)|<a href="http://bts.example.org/issue\1">issue\1</a>|i
italic = s/\b_(\S+)_\b/<i>\1<\/i>/
bold = s/\*\b(\S+)\b\*/<b>\1<\/b>/
worker
Parallel master/worker configuration. We currently perform working
directory updates in parallel on Unix-like systems, which greatly helps
performance.
numcpus
Number of CPUs to use for parallel operations. Default is 4 or
the number of CPUs on the system, whichever is larger. A zero or
negative value is treated as use the default.
