## description (for backend authors):
|
|
# action: a string that signals a certain non-default condition in the
|
|
# repository (like 'rebase-i' in git). If this in non-empty,
|
|
# the actionformats will be used, too.
|
|
# branch: the name of the currently checked out branch.
|
|
# base: the full name of the repository's root directory.
|
|
# staged: non-empty if the repository contains staged changes.
|
|
# unstaged: non-empty if the repository contains unstaged changes.
|
|
# revision: an identifier of the currently checked out revision.
|
|
# misc: a string that may contain anything the backend author likes.
|
|
#
|
|
# If an argument has no valid value for a given backend, an empty value
|
|
# should be provided. eg:
|
|
# VCS_INFO_formats '' "${foobranch}" "${foobase}" '' '' '' "${foomisc}"
|
|
|
|
## description (vcs_info internals):
|
|
# This function is called by the backend with information about the repository,
|
|
# and (after some manipulations) populates the ${msgs} variable in preparation
|
|
# for calling VCS_INFO_set.
