This repo contains the entire source code for each step of kilo-tutorial. Each step is represented by a commit. Each step name (found in the upper-right corner of each step diff in the tutorial) is a ref to that step's commit.
If you want to compare your version of kilo.c with the version in this repo
for a particular step, say keypresses, you could do it like this:
$ git clone https://github.com/snaptoken/kilo-src
$ cd kilo-src
$ git checkout keypresses
$ git diff --no-index -b ../path/to/your/kilo.c kilo.c
--no-index lets you use git diff as an ordinary diff tool, and -b ignores
differences in whitespace, which is important if you use a different indent
style than the one in the tutorial.
