GitHub Actions can't access private repos? Here's how to fix it

Tue, 13 Sep 2022 12:01:45 +0800

When developing locally, you can add a private GitHub repository to your Rust crate as a git dependency and cargo should be able to retrieve it just fine.

However, when you push your changes to GitHub and run CI, GitHub Actions can run into authentication issues when trying to build your crate.

This is the error message I was fighting for a good part of today:

$ cargo check --workspace --verbose --locked

Cargo can’t check out my private repository!

Announcing Cargo WAPM

While at Hammer of the Gods, we wrote a lot of Rust code that gets compiled to WebAssembly for use in our containerization technology, Rune.

We have over 30 different processing blocks (chunks of code that can be used in a data processing pipeline) and as you can imagine, publishing and versioning each of WebAssembly module manually isn’t practical. For that, we lean on the WebAssembly Package Manager to do all the heavy lifting.

Creating a Robust, Reusable Link-Checker

Sat, 02 May 2020 19:20:00 +0800

With over 68,842 downloads, one of my most successful Rust projects is a nondescript little program called mdbook-linkcheck . This is a link-checker for mdbook , the tool powering a lot of documentation in the Rust community, including The Rust Programming Language and The Rustc Dev Book .

As an example of what it looks like, I recently found a couple broken links in the documentation for Chalk. When the tool detects broken links in your markdown it’ll emit error messages that point you at the place the link is defined and explain what the issue is.

I Made A Thing: Markedit

A couple days ago I released markedit , a small crate for editing unstructured markdown documents. This is a useful enough library that I thought I’d explain the main ideas behind it and potential use cases.

This originally came about when I was at work, preparing our application’s change log before a release for the umpteenth time (we’ve found the keep a changelog format really useful) and on the drive home I started thinking of ways to automate things.
