The code for each post now lives in the `post-XX` branches where `XX` is the post number.
Blog OS
This repository contains the source code for the Writing an OS in Rust series at os.phil-opp.com.
Where is the code?
The code for each post lives in a separate git branch. This makes it possible to see the intermediate state after each post. You can find the branch for each post by following the (source code) link in the post list below. The branches are named post-XX where XX is the post number, for example post-03 for the third post ("VGA Text Mode").
You can find the code for the latest post here.
For build instructions, see the Readme of the post branches.
Checking out the Code in a Subdirectory
To check out the code in a subdirectory use git worktree:
git worktree add code post-10
This creates a subdirectory named code that contains the code for the latest post ("Advanced Paging").
