-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
-
-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.
