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, use .hgrc)
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.
HGMERGE
An executable to use for resolving merge conflicts. The program
will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, use .hgrc)
HGRCPATH
A list of files or directories to search for hgrc 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
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)
- hgrc files from the HGRCPATH
- EMAIL
- interactive prompt
- LOGNAME (with ``@hostname`` appended)
(deprecated, use .hgrc)
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.
