Forgit me nots

Squashing commits on Windows

I know there's a better way to do this (using rebase) but I like this way since it gives me more control.

git merge-base main yourBranch

# note commit hash

git reset --soft # enter commit hash

# all changes can now be committed again

It's easier on *nix using the following oneliner:

git reset $(git merge-base main $(git rev-parse --abbrev-ref HEAD))

Rebasing without pulling main

Rebase using the remote main to make sure you're really up to date. Useful when updating merge requests (on GitLab).

git pull --rebase origin main

Copy file from main to current branch

git checkout main -- yarn.lock

Useful aliases

Add all and commit

ac=!git add . && git commit

Pretty log

ls = log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit

Update last commit with current changes

amen = !git add --all && git commit --amend

Undo last commit

git reset --soft HEAD^

Or add as an alias:

git config --global alias.undo 'reset --soft HEAD^'

Oh no, I deleted all my work!?

Use the following command:

git reflog

and cherry-pick any commits you think could still have all your work.

If .gitignore is not working


git rm -r --cached .

And after that:

git add --all

Case insensitivity MacOS

MacOS by default ignores case in filenames and directories. Those differences go unnoticed until you push your working code to CI, where the build fails. To fix this once and for all use:

git config --global core.ignorecase false

After Rebasing

Instead of using -f or --force developers should use

git push --force-with-lease

Why? Because it checks the remote branch for changes which is a good idea. Let's imagine that James and Lisa are working on the same feature branch and Lisa has pushed a commit. James now rebases his local branch and is rejected when trying to push. Of course James thinks this is due to rebase and uses --force and would rewrite all Lisa's changes. If James had used --force-with-lease he would have received a warning that there are commits done by someone else. I don't see why anyone would use --force instead of --force-with-lease when pushing after a rebase.
