I'm sometimes getting

NoMethodError at /self-updating-screenshots undefined method `name' for nil:NilClass

Ruby title-for: in handle, line 12 Web GET interblah.net/self-updating-screenshots

followed by a very detailed traceback when I try to access the page

same here, but linking to the screenshots used for pixel diffing, which get committed to the repo.

I’ve wondered about doing screenshots from the e2e test run, even keeping docs/ all together in the same repo so when you update the documentation and need a new screenshot you add a new test

I maintain an internal wiki, the contents were generated by each CI/CD and always reflects from latest running code.

shot-scraper is another project in this vein.

Really love this, it should be standard practice!

I wrote a gui app once that ran on a safety-critical platform. I ended up stuffing a rendering of the gui (rendered offscreen) into shmem at I think 24hz, and rendered that screenshot into the safety critical application. I passed clicks (no typing for this gui) back from the statically rendered image updating on a cadence, to the offscreen GUI.

Worked well. Not quite the same as this, but that’s what this reminds me of.

nice, embedding the capture instructions right in the markdown as comments is a dead-simple solution that'll age way better than any fancy external tooling
