    46 HGEDITOR::

    47     This is the name of the editor to use when committing. Defaults to the

    48     value of EDITOR.

    49 

    50     (deprecated, use .hgrc)

    51 

    52 HGENCODING::

    53     This overrides the default locale setting detected by Mercurial.

    54     This setting is used to convert data including usernames,

    55     changeset descriptions, tag names, and branches. This setting can

    56     be overridden with the --encoding command-line option.

    57 

    58 HGENCODINGMODE::

    59     This sets Mercurial's behavior for handling unknown characters

    60     while transcoding user inputs. The default is "strict", which

    61     causes Mercurial to abort if it can't translate a character. Other

    62     settings include "replace", which replaces unknown characters, and

    63     "ignore", which drops them. This setting can be overridden with

    64     the --encodingmode command-line option.

    65 

    66 HGMERGE::

    67     An executable to use for resolving merge conflicts. The program

    68     will be executed with three arguments: local file, remote file,

    69     ancestor file.

    70 

    71     The default program is "hgmerge", which is a shell script provided

    72     by Mercurial with some sensible defaults.

    73 

    74     (deprecated, use .hgrc)

    75 

    76 HGRCPATH::

    77     A list of files or directories to search for hgrc files.  Item

    78     separator is ":" on Unix, ";" on Windows.  If HGRCPATH is not set,

    79     platform default search path is used.  If empty, only .hg/hgrc of

    80     current repository is read.

    81 

    82     For each element in path, if a directory, all entries in directory

    83     ending with ".rc" are added to path.  Else, element itself is

    84     added to path.

    85 

    86 HGUSER::

    87     This is the string used for the author of a commit.

    88 

    89     (deprecated, use .hgrc)

    90 

    91 EMAIL::

    92     If HGUSER is not set, this will be used as the author for a commit.

    93 

    94 LOGNAME::

    95     If neither HGUSER nor EMAIL is set, LOGNAME will be used (with

    96     '@hostname' appended) as the author value for a commit.

    97 

    98 EDITOR::

    99     This is the name of the editor used in the hgmerge script. It will be

   100     used for commit messages if HGEDITOR isn't set. Defaults to 'vi'.

   101 

   102 PYTHONPATH::

   103     This is used by Python to find imported modules and may need to be set

   104     appropriately if Mercurial is not installed system-wide.
