The command may not be the best place to add this new feature, but
$ git check-ref-format --branch "@{-1}"
allows Porcelains to figure out what branch you were on before the last
branch switching.

|
|
git-check-ref-format - Make sure ref name is well formed
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git check-ref-format' <refname>
|
|
'git check-ref-format' [--branch] <branchname-shorthand>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Checks if a given 'refname' is acceptable, and exits non-zero if
|
|
it is not.
|
|
|
|
A reference is used in git to specify branches and tags. A
|
|
branch head is stored under `$GIT_DIR/refs/heads` directory, and
|
|
a tag is stored under `$GIT_DIR/refs/tags` directory. git
|
|
imposes the following rules on how refs are named:
|
|
|
|
. It can include slash `/` for hierarchical (directory)
|
|
grouping, but no slash-separated component can begin with a
|
|
dot `.`;
|
|
|
|
. It cannot have two consecutive dots `..` anywhere;
|
|
|
|
. It cannot have ASCII control character (i.e. bytes whose
|
|
values are lower than \040, or \177 `DEL`), space, tilde `~`,
|
|
caret `{caret}`, colon `:`, question-mark `?`, asterisk `*`,
|
|
or open bracket `[` anywhere;
|
|
|
|
. It cannot end with a slash `/`.
|
|
|
|
These rules makes it easy for shell script based tools to parse
|
|
refnames, pathname expansion by the shell when a refname is used
|
|
unquoted (by mistake), and also avoids ambiguities in certain
|
|
refname expressions (see linkgit:git-rev-parse[1]). Namely:
|
|
|
|
. double-dot `..` are often used as in `ref1..ref2`, and in some
|
|
context this notation means `{caret}ref1 ref2` (i.e. not in
|
|
ref1 and in ref2).
|
|
|
|
. tilde `~` and caret `{caret}` are used to introduce postfix
|
|
'nth parent' and 'peel onion' operation.
|
|
|
|
. colon `:` is used as in `srcref:dstref` to mean "use srcref\'s
|
|
value and store it in dstref" in fetch and push operations.
|
|
It may also be used to select a specific object such as with
|
|
'git-cat-file': "git cat-file blob v1.3.3:refs.c".
|
|
|
|
With the `--branch` option, it expands a branch name shorthand and
|
|
prints the name of the branch the shorthand refers to.
|
