- HG
- Path to the 'hg' executable, automatically passed when running
hooks, extensions or external tools. If unset or empty, this is
the hg executable's name if it's frozen, or an executable named
'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on
Windows) is searched.
- HGEDITOR
This is the name of the editor to run when committing. See EDITOR.
(deprecated, see hg help config.ui.editor)
- HGENCODING
- This overrides the default locale setting detected by Mercurial.
This setting is used to convert data including usernames,
changeset descriptions, tag names, and branches. This setting can
be overridden with the --encoding command-line option.
- HGENCODINGMODE
- This sets Mercurial's behavior for handling unknown characters
while transcoding user input. The default is "strict", which
causes Mercurial to abort if it can't map a character. Other
settings include "replace", which replaces unknown characters, and
"ignore", which drops them. This setting can be overridden with
the --encodingmode command-line option.
- HGENCODINGAMBIGUOUS
- This sets Mercurial's behavior for handling characters with
"ambiguous" widths like accented Latin characters with East Asian
fonts. By default, Mercurial assumes ambiguous characters are
narrow, set this variable to "wide" if such characters cause
formatting problems.
- HGMERGE
An executable to use for resolving merge conflicts. The program
will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, see hg help config.ui.merge)
- HGRCPATH
A list of files or directories to search for configuration
files. Item separator is ":" on Unix, ";" on Windows. If HGRCPATH
is not set, platform default search path is used. If empty, only
the .hg/hgrc from the current repository is read.
For each element in HGRCPATH:
- if it's a directory, all files ending with .rc are added
- otherwise, the file itself will be added
- HGRCSKIPREPO
- When set, the .hg/hgrc from repositories are not read.
- HGPLAIN
When set, this disables any configuration settings that might
change Mercurial's default output. This includes encoding,
defaults, verbose mode, debug mode, quiet mode, tracebacks, and
localization. This can be useful when scripting against Mercurial
in the face of existing user configuration.
In addition to the features disabled by HGPLAIN=, the following
values can be specified to adjust behavior:
- +strictflags
- Restrict parsing of command line flags.
Equivalent options set via command line flags or environment
variables are not overridden.
See hg help scripting for details.
- HGPLAINEXCEPT
This is a comma-separated list of features to preserve when
HGPLAIN is enabled. Currently the following values are supported:
- alias
- Don't remove aliases.
- color
- Don't disable colored output.
- i18n
- Preserve internationalization.
- revsetalias
- Don't remove revset aliases.
- templatealias
- Don't remove template aliases.
- progress
- Don't hide progress output.
Setting HGPLAINEXCEPT to anything (even an empty string) will
enable plain mode.
- HGUSER
This is the string used as the author of a commit. If not set,
available values will be considered in this order:
- HGUSER (deprecated)
- configuration files from the HGRCPATH
- EMAIL
- interactive prompt
- LOGNAME (with @hostname appended)
(deprecated, see hg help config.ui.username)
- EMAIL
- May be used as the author of a commit; see HGUSER.
- LOGNAME
- May be used as the author of a commit; see HGUSER.
- VISUAL
- This is the name of the editor to use when committing. See EDITOR.
- EDITOR
- Sometimes Mercurial needs to open a text file in an editor for a
user to modify, for example when writing commit messages. The
editor it uses is determined by looking at the environment
variables HGEDITOR, VISUAL and EDITOR, in that order. The first
non-empty one is chosen. If all of them are empty, the editor
defaults to 'vi'.
- PYTHONPATH
- This is used by Python to find imported modules and may need to be
set appropriately if this Mercurial is not installed system-wide.
