SYNOPSIS

+[verse]
'. "$(git --exec-path)/git-sh-setup"'
DESCRIPTION
The 'git sh-setup' scriptlet is designed to be sourced (using
`.`) by other shell scripts to set up some variables pointing at
-the normal git directories and a few helper shell functions.
+the normal Git directories and a few helper shell functions.
Before sourcing it, your script should set up a few variables;
`USAGE` (and `LONG_USAGE`, if any) is used to define message
die with the usage message.
set_reflog_action::
- set the message that will be recorded to describe the
- end-user action in the reflog, when the script updates a
- ref.
+ Set GIT_REFLOG_ACTION environment to a given string (typically
+ the name of the program) unless it is already set. Whenever
+ the script runs a `git` command that updates refs, a reflog
+ entry is created using the value of this string to leave the
+ record of what command updated the ref.
git_editor::
runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or
cd_to_toplevel, which is impossible to do if there is no
working tree.
+require_clean_work_tree <action> [<hint>]::
+ checks that the working tree and index associated with the
+ repository have no uncommitted changes to tracked files.
+ Otherwise it emits an error message of the form `Cannot
+ <action>: <reason>. <hint>`, and dies. Example:
++
+----------------
+require_clean_work_tree rebase "Please commit or stash them."
+----------------
+
get_author_ident_from_commit::
outputs code for use with eval to set the GIT_AUTHOR_NAME,
GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
+create_virtual_base::
+ modifies the first file so only lines in common with the
+ second file remain. If there is insufficient common material,
+ then the first file is left empty. The result is suitable
+ as a virtual base input for a 3-way merge.
