We presently use the ".txt" extension for our AsciiDoc files. While not wrong, most editors do not associate this extension with AsciiDoc, meaning that contributors don't get automatic editor functionality that could be useful, such as syntax highlighting and prose linting. It is much more common to use the ".adoc" extension for AsciiDoc files, since this helps editors automatically detect files and also allows various forges to provide rich (HTML-like) rendering. Let's do that here, renaming all of the files and updating the includes where relevant. Adjust the various build scripts and makefiles to use the new extension as well. Note that this should not result in any user-visible changes to the documentation. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

NAME

|
----
|
|
git-symbolic-ref - Read, modify and delete symbolic refs
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git symbolic-ref' [-m <reason>] <name> <ref>
|
|
'git symbolic-ref' [-q] [--short] [--no-recurse] <name>
|
|
'git symbolic-ref' --delete [-q] <name>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Given one argument, reads which branch head the given symbolic
|
|
ref refers to and outputs its path, relative to the `.git/`
|
|
directory. Typically you would give `HEAD` as the <name>
|
|
argument to see which branch your working tree is on.
|
|
|
|
Given two arguments, creates or updates a symbolic ref <name> to
|
|
point at the given branch <ref>.
|
|
|
|
Given `--delete` and an additional argument, deletes the given
|
|
symbolic ref.
|
|
|
|
A symbolic ref is a regular file that stores a string that
|
|
begins with `ref: refs/`. For example, your `.git/HEAD` is
|
|
a regular file whose content is `ref: refs/heads/master`.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-d::
|
|
--delete::
|
|
Delete the symbolic ref <name>.
|
|
|
|
-q::
|
|
--quiet::
|
|
Do not issue an error message if the <name> is not a
|
|
symbolic ref but a detached HEAD; instead exit with
|
|
non-zero status silently.
|
|
|
|
--short::
|
|
When showing the value of <name> as a symbolic ref, try to shorten the
|
|
value, e.g. from `refs/heads/master` to `master`.
|
|
|
|
--recurse::
|
|
--no-recurse::
|
|
When showing the value of <name> as a symbolic ref, if
|
|
<name> refers to another symbolic ref, follow such a chain
|
|
of symbolic refs until the result no longer points at a
|
|
symbolic ref (`--recurse`, which is the default).
|
|
`--no-recurse` stops after dereferencing only a single level
|
|
of symbolic ref.
|
|
|
|
-m::
|
|
Update the reflog for <name> with <reason>. This is valid only
|
|
when creating or updating a symbolic ref.
|
|
|
|
NOTES
|
|
-----
|
|
In the past, `.git/HEAD` was a symbolic link pointing at
|
|
`refs/heads/master`. When we wanted to switch to another branch,
|
|
we did `ln -sf refs/heads/newbranch .git/HEAD`, and when we wanted
|
|
to find out which branch we are on, we did `readlink .git/HEAD`.
|
|
But symbolic links are not entirely portable, so they are now
|
|
deprecated and symbolic refs (as described above) are used by
|
|
default.
|
|
|
|
'git symbolic-ref' will exit with status 0 if the contents of the
|
|
symbolic ref were printed correctly, with status 1 if the requested
|
|
name is not a symbolic ref, or 128 if another error occurs.
