It is possible to specify in the hgrc file that one of the internal merge
tools (internal:fail, internal:local or internal:other) be used for
performing merges on files matching a given pattern. However, this setting
is not being acted upon (the merge tool is not found). This patch fixes that.
if ui.merge matches a tool in [merge-tools], it is used as the
default tool selection but may be rejected by binary or gui or
other checks. If ui.merge does not match a merge tool, it is
used unconditionally.
Add [merge-tool] hgrc section with:
<tool>.executable = name or path (<tool>)
<tool>.args = args with $local/base/other/output ($local $base $other)
<tool>.priority = priority (default 0)
<tool>.binary = handles binary (False)
<tool>.symlink = handles symlinks (False)
<tool>.checkconflict = check for conflict markers (False)
<tool>.premerge = try internal simplemerge (True if not binary or symlink)
Four built-in tools: internal:{merge,local,other,fail}
Add [merge-patterns] section of the form:
<pattern> = <tool>
Priority of settings is:
HGMERGE
merge-patterns
ui:merge
merge-tools by priority
hgmerge, if it can be found
Changes:
unsuccessful merges leave .orig files
