summary on some steps in the git workflow
Table of contents
terminology
| term | description |
|---|---|
^ |
one commit back (in history), use <HEAD/branch/commit_hash>^ |
| head | pointer to branch (usually latest commit, unless detached=pointer to specific commit) currently checked out locally |
| index | keeps track of staged/cached (with git add) changes |
| working tree | local file working directory |
branches
create a branch
To create a branch use subcommand branch or checkout with flag -b:
# create new branch ('base-branch' is optional)
git branch <branch-name> <base-branch>
git checkout -b <branch-name> <base-branch>
# switch branch ('checkout -b' combines the 'branch' and 'switch' subcommands)
git switch <branch-name>
submodules
To fetch submodules of a cloned repository use:
# do it manually
git submodule init
git submodule update
# do it all at once
git clone --recurse-submodules
# if repo is already cloned
git submodule update --init --recursive
removing files from index
To remove files from index without deleting them on disk, use:
git rm --cached <file-name>
This is helpful if one accidentally committed autogenerated files.
philosophies
Important things to always remember: - do renaming in seperate commit - don't merge conflicts with directories
merge
When following the philosophie of merging, one merges the target branch into ones working, solves all conflicts, tests the result and then merges the working branch into the target branch. This is done with
# merges 'target-branch' into curret branch
git merge <target-branch>
# proceeds after solving merge conflict
git merge --continue
rebase
When following the philosophie of rebasing, one rebases the feature branch onto the target branch. This is done with
# rebases current branch onto 'target-branch'
git rebase <target-branch>
# proceeds after solving rebase conflict
git rebase --continue
