Free isn’t free: the infrastructure behind open source has real costs, and it’s time we aligned usage with responsibility.

This morning we jointly launch a new blog and open letter on sustainable stewardship.

git add -p

(this is bonus comic #4 for "How Git Works" wizardzines.com/zines/git, covering some topics that I didn't have space for in the zine)

permalink: wizardzines.com/comics/git-a...

panel 1: git add -p lets you stage some changes and not others

(this is one of the tasks GUIs and IDEs are best at, but I always use git add -p anyway)

panel 2: what the interface looks like

filename, diff, your choice ("Stage this hunk [y,n,q,a,d,s,e,?]")

panel 3: y(es)/n(o)/q(uit)

y means "stage this change"

n means "don't"

q quits, keeping what you did so far. pretty straightforward.

panel 4: how to check your work

git diff --cached

will show your staged changes

panel 5: s: split into 2 parts

s will split a diff into smaller diffs you can say y or n to individually, like this:

panel 6: how to split a diff if there's no newline

You can use the e ("edit") option to edit the diff manually:

* to remove a - line, replace "-" with a space
* to remove a + line, delete the whole line

(or you can just say 'n' and edit your code! that's what I do!)

interactive rebase

(this is bonus comic #1 for How Git Works https://wizardzines.com/zines/git, covering some topics that didn't make it into the zine!)

panel 1: git rebase -i
lets you garden your commits

I use it like this:
1. make commits chaotically, git commit -am 'wip'
2. clean up with git rebase -i before sending them off for code review

panel 2: interactive rebase's UI is a text file

when you run git rebase -i main, it'll open a text editor with something like this in it:

pick 399990 add some padding
pick fb59d8 french translation
pick 617b19 sort titles
pick 31b81f hashchange

panel 3: deleting commits

You can delete a commit just by deleting that line in the text editor!

(the line "french translation" is crossed out)

panel 4: combine commits with fixup

Here's how to combine all 4 commits into 1 commit:
(f stands for fixup)

pick 399990 add some padding
f fb59d8 french translation
f 617b19 sort titles
f 31b81f hashchange

panel 5: check that the tests pass with exec

You can run make test on every intermediate commit to make sure your tests pass like this:

git rebase -i --exec "make test" main

(you can also use this to format every commit's code!)

panel 6: some other tips

* reword lets you edit a commit message
* If something goes very wrong, I try to run git rebase --abort ASAP, because undoing rebases is annoying
