I am working on a project and I want to see how it worked in its latest edition. How can I do this without losing my changes?

Question

In particular, I use bzr, but tips for any VCS are welcome.

Answer 1

I think there are three options.

• Use shelving

  bzr shelve --all
bzr unshelve

• Create a separate branch using the latest

• Create a patch from you modifies and discards the changes. Apply the patch when you need to change back.

Answer 2

Using Git :

git checkout HEAD^    # get the previous version, changing files on disk to match
make                  # run your project (or whatever command you use)
git checkout master   # return to the "master" branch

, , , . , , stash:

git stash             # save the uncommitted changes away
make                  # ...
git stash pop         # restore your uncommitted changes

; Git " ".
