Querying the GitHub GraphQL API

In a recent project around open source contributors, I wanted to take a look at which projects a particular user (actually a few of them, but I wrote a wrapper to repeat the process for each handle) maintains. GitHub doesn’t show this maintainer relationship, so instead I used the v4 GraphQL API and looked at pull request comments on repositories that the user has access to. I’m sharing my query and the Python script I used to make the API calls to. Continue reading →

Run GitHub Actions on Subdirectories

I come across a lot of “greedy” GitHub Actions, where automation is running across a whole project instead of only on the parts that are relevant. Examples might be code linters that report problems with documentation folders, or the inverse of that. It’s especially problematic in monorepos where we probably want to use the same tool when we’re doing the same task for different subfolders, but that tool might not make sense to run everywhere.

Use multi-line values in GitHub Actions

I created an action that needed a rich Markdown value in it, because it’s our weekly meeting agenda template which is formatted for humans with links and paragraphs and things. The Action syntax produced errors when trying to add the content directly to the action, but I got it to work by putting the content into the file, and using the file contents as an environment variable. That’s really the punchline of this post, but read on if you would like more details and some examples. Continue reading →

How to structure and share code examples

Writing for technical audiences often means sharing code in one form or another. If the code is only for illustration purposes, then it can be included in the article for observation. But if the code is useful or reusable by your readers, then you need a way to make it available to them. I’ve seen a few questions on this recently (shout out to the DevRel Collective slack for a brilliant discussion AND nagging me to write it up as a post!), so I’m sharing my experiences on how to publish and maintain code in sane ways!

Reviewdog filter settings with GitHub Actions

Reviewdog is a tool to use with GitHub actions for applying review tools in your CI. I use it with Vale, and it’s really good. One thing that has tripped me up multiple times is that by default, it only applies the checks to the changes in the pull request, not to the whole project. So when you add something like Vale, which is a prose linter, it only checks … the workflow file you just added! I always forget that it works this way, and how to change it, so I’m pasting some examples for future reference. Continue reading →

Visualise OpenAPI with Blockly

Giving talks about OpenAPI often means lots and lots of slides of YAML. In fact, one of my talks even contains a “warning, contains yaml” slide! If you aren’t a professional yaml developer, it can be difficult to digest and learn from, and so I wanted to do better. The various elements are nested inside one another, and so I had this idea to build a representation of OpenAPI using Blockly (the tooling also used for Scratch, if you’ve seen that).

Measuring Repo Community Health with GitHub’s API

I’m on record saying that GitHub is your Landing Page and when I think about companies having open source profiles, I think about how many developers will have the first contact with them on GitHub. If it’s a code example you’re looking for then like it or not, GitHub is considered a search engine by many developers.

With that in mind, I wanted to look at GitHub’s Community Health measure of the repositories I’m responsible for. You can view each repo’s community page separately through the web interface (look under “Insights”) but that’s not especially scalable if you have a lot of projects to track.

Bystanders Guide to Repository Maintenance

Today’s post is about bystanders and open source. We sometimes have anxiety about doing things on “other people’s” projects but the thing about open source is that those are not “their” projects, those are “our” projects, and they only exist because people other than their nominated gatekeepers chip in now and then.
