git-mergetool--lib(1)
=====================
NAME
----
git-mergetool--lib - Common git merge tool shell scriptlets
SYNOPSIS
--------
'. "$(git --exec-path)/git-mergetool--lib"'
DESCRIPTION
-----------
This is not a command the end user would want to run. Ever.
This documentation is meant for people who are studying the
Porcelain-ish scripts and/or are writing new ones.
The 'git-mergetool--lib' scriptlet is designed to be sourced (using
`.`) by other shell scripts to set up functions for working
with git merge tools.
Before sourcing it, your script should set up a few variables;
`TOOL_MODE` is used to define the operation mode for various
functions. 'diff' and 'merge' are valid values.
FUNCTIONS
---------
get_merge_tool::
returns a merge tool
get_merge_tool_cmd::
returns the custom command for a merge tool.
get_merge_tool_path::
returns the custom path for a merge tool.
run_merge_tool::
launches a merge tool given the tool name and a true/false
flag to indicate whether a merge base is present.
'$merge_tool', '$merge_tool_path', and for custom commands,
'$merge_tool_cmd', must be defined prior to calling
run_merge_tool. Additionally, '$MERGED', '$LOCAL', '$REMOTE',
and '$BASE' must be defined for use by the merge tool.
