Git for Darcs Users
Just like Darcs, every Git command comes with a --help option. For example git add --help. You can also check out the official Git documentation.
Also see "General Notes" below for features present in Git but not in Darcs.
Just like Darcs, Git has global and per-repository configuration options. To globally set your committer name and email use
git config --global user.name "Haskell Curry" git config --global user.email [email protected]
git clone <repo-url> [<local-name>]
Possible repo URLs look like this:
git clone http://darcs.haskell.org/ghc.git # via HTTP (slowest) git clone git://darcs.haskell.org/ghc.git # git's protocol (fast, read-only) git clone [username@]darcs.haskell.org:ghc.git # via SSH
git add <dir-or-file>
Git supports interactive recording very similar to darcs.
git add -p
git add -i
The main difference is that Git does not automatically commit the changes. You have to do that manually using
git commit [-m "commit message"]
If you do not supply a commit message, it will open your default editor. If you want to abort the commit, use an empty commit message.
To see what will be committed, use
git diff --cached
Tip: If you want to see the diff when you edit the commit message, use
git commit -v
There is a direct mapping to darcs pull -a. Cherry-picking is not as streamlined as in Darcs. For a start, here is how you update from the source repo:
If all you want to do is to keep updated then this is fine. The above is actually a shortcut for
git pull origin
where origin is the name of your default remote branch. (You can name it as you like, but certain Git commands will use origin as the default if no argument is specified.)
XXX: will this pull into the current branch, or always into master?
Like in Darcs, you may get conflicts. To resolve conflicts, edit the conflicting file, git add it, and git commit it.
If you want to see whether you get conflicts before pulling git pull is actually ... XXX
darcs record -a
git commit -a
This will add and commit all (not ignored) files. It will not add newly created files. (To do this call git add . before in the repo root directory.)
git log git log <file-or-directory>
darcs changes --last <N>
git log -n <N>
darcs changes --summary
git log --stat
darcs changes --match
git log --grep="something"
(the =-sign is important)
Other useful variants
git log -p
Shows the patch for each commit.
git grep <text>
Look for something anywhere in the repository's history (tag names, commit messages, file contents).
git show <commit-id>
Show the changes by the given patch
git log v2.5..v2.6 # commits between v2.5 and v2.6 git log v2.5.. # commits since v2.5 git log --since="2 weeks ago" # commits from the last 2 weeks git log v2.5.. Makefile # commits since v2.5 which modify # Makefile
See git log --help for a lot of extra options, to refine the output.
git tag <tagname>
This will fail if the tag already exists. If you want to move an existing tag use git tag -f <tagname>, but never move a tag in a public repo/branch. Use this only on local branches, and only if the tag exists nowhere else. git tag --help contains a discussion of this.
git diff <commit1>..<commit2> # show diff between two commits
git reset --hard
Note: git reset only resets the staged files, i.e., the things added with git add.
git reset --soft HEAD^
If the change to be amended is the latest commit
git commit --amend
TODO describe workflow if amended patch is not the current HEAD.
TODO add note for merge commits
git revert <commit-id>
Working directory must be clean. (You can use git stash to save local changes).
git branch git branch <name> git branch -b <name> git checkout git branch -d <name> git branch -D <name> git stash git show-branch
git pull git fetch git merge
