4 NAME
5 ----
6 git-sh-setup - Common git shell script setup code
8 SYNOPSIS
9 --------
10 'git-sh-setup'
12 DESCRIPTION
13 -----------
15 This is not a command the end user would want to run. Ever.
16 This documentation is meant for people who are studying the
17 Porcelain-ish scripts and/or are writing new ones.
19 The `git-sh-setup` scriptlet is designed to be sourced (using
20 `.`) by other shell scripts to set up some variables pointing at
21 the normal git directories and a few helper shell functions.
23 Before sourcing it, your script should set up a few variables;
24 `USAGE` (and `LONG_USAGE`, if any) is used to define message
25 given by `usage()` shell function. `SUBDIRECTORY_OK` can be set
26 if the script can run from a subdirectory of the working tree
27 (some commands do not).
29 The scriptlet sets `GIT_DIR` and `GIT_OBJECT_DIRECTORY` shell
30 variables, but does *not* export them to the environment.
32 FUNCTIONS
33 ---------
35 die::
36 exit after emitting the supplied error message to the
37 standard error stream.
39 usage::
40 die with the usage message.
42 set_reflog_action::
43 set the message that will be recorded to describe the
44 end-user action in the reflog, when the script updates a
45 ref.
47 git_editor::
48 runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or
49 EDITOR) on a given file, but error out if no editor is specified
50 and the terminal is dumb.
52 is_bare_repository::
53 outputs `true` or `false` to the standard output stream
54 to indicate if the repository is a bare repository
55 (i.e. without an associated working tree).
57 cd_to_toplevel::
58 runs chdir to the toplevel of the working tree.
60 require_work_tree::
61 checks if the repository is a bare repository, and dies
62 if so. Used by scripts that require working tree
63 (e.g. `checkout`).
65 get_author_ident_from_commit::
66 outputs code for use with eval to set the GIT_AUTHOR_NAME,
67 GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit.
