--skip-worktree and operations like checkout / stash /etc.

[Raman Gupta]

The comand `update-index --skip-worktree` seems to be an ideal way to
tell git to locally ignore some modified files. However, this seems
not to play well with very common commands like `checkout` and
`stash`.

$ git checkout other-branch
error: Your local changes to the following files would be overwritten
by checkout:
        path/to/ignored/file
Please commit your changes or stash them before you switch branches.
Aborting

Ok, well lets try stashing:

$ git stash save
No local changes to save

Ok, lets try a checkout with a merge:

$ git checkout -m other-branch
error: Entry 'path/to/ignored/file' not uptodate. Cannot merge.

Ok, lets force this sucker:

$ git checkout -f other-branch
error: Entry 'path/to/ignored/file' not uptodate. Cannot merge.

Ok, at this point I'm wondering, do I really need to
--no-skip-worktree all the ignored files, do my `checkout -m`, and
then ignore them again? Umm, no, that ain't gonna work.

I'd love for git to just check if my worktree-skipped changes will
merge cleanly into the target branch, and if they do so, go ahead and
do that merge (with perhaps a notification printed to the console) and
keep the skip worktree status. If the merge ends up with a conflict,
then feel free to no-worktree-skip it and show me merge conflicts.

Raman

In the meantime I've created this simple script, but what a hack...

#!/bin/bash
git ls-files -v | grep "^S " | cut -c3- | readarray ignored
for x in "${ignored[@]}"; do
  git update-index --no-skip-worktree -- "$x"
done
git checkout -m $@
for x in "${ignored[@]}"; do
  git update-index --skip-worktree -- "$x"
done

Raman
