Environment Variables
"""""""""""""""""""""

    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.
