How to make "git describe" indicate the presence or absence of local changes?

Question

How can I check in a script if local changes are present? Perhaps combined with git describe?

Answer 1

You need to make sure that both of the following properties are true:

• There is no difference between HEAD and index cache

  git diff-index --cached HEAD

• There are no differences between the index and the working tree:

  git diff-files

--quiet, ( git 1.4). git 1.4, --quiet , - .

. git diff - . .

, git_version.sh script:

git_dirty=yes
# git-1.4 does not understand "git-diff-files --quiet"
# git-1.4 does not understand "git-diff-index --cached --quiet HEAD"
if [ "x$($GIT diff-files)" = "x" ] && [ "x$($GIT diff-index --cached HEAD)" = "x" ]; then
    git_dirty=no
fi

git version >= 1.5, if git diff-files --quiet && git diff-index --quiet --cached HEAD; then .

. ( , Antony interactive git diff HEAD --quiet) HEAD. , , , , , HEAD. SHA1 git describe, , HEAD , .

Answer 2

git 1.6.6, git-describe --dirty. , :

$ git describe --dirty
1.0.2-2-g215081f-dirty

Answer 3

git diff --quiet 1, 0, .

, . HEAD , git diff HEAD --quiet.

--quiet --exit-code.

Answer 4

git status exits with non-zero status if there are no local changes.

But I don’t understand what you mean "combined with git describe."
