And now thanks to me, the name "Slackware" will be embedded in the Ruby source code 🙃

Yay, looks like the regexp performance regression in Ruby 4.0 is fixed! 🎉 #ruby #rubylang

Also, it's possible to decode the tokens from base64 and then from JSON, and look at the expiry timestamps there: (this is issue time + expiry time for AT & RT before and after refresh, notice that everything is offset by 40s in the second section)
> sky.user.access_token.split('.')[1].then { |x| Base64.decode64(x) }.then { |x| JSON.parse(x) }.then { |x| puts "access token: from #{Time.at(x['iat'])} to #{Time.at(x['exp'])}" } access token: from 2026-01-13 04:58:07 +0200 to 2026-01-13 06:58:07 +0200 > sky.user.refresh_token.split('.')[1].then { |x| Base64.decode64(x) }.then { |x| JSON.parse(x) }.then { |x| puts "refresh token: from #{Time.at(x['iat'])} to #{Time.at(x['exp'])}" } refresh token: from 2026-01-13 04:58:07 +0200 to 2026-04-13 05:58:07 +0300 > sky.perform_token_refresh > sky.user.access_token.split('.')[1].then { |x| Base64.decode64(x) }.then { |x| JSON.parse(x) }.then { |x| puts "access token: from #{Time.at(x['iat'])} to #{Time.at(x['exp'])}" } access token: from 2026-01-13 04:58:47 +0200 to 2026-01-13 06:58:47 +0200 > sky.user.refresh_token.split('.')[1].then { |x| Base64.decode64(x) }.then { |x| JSON.parse(x) }.then { |x| puts "refresh token: from #{Time.at(x['iat'])} to #{Time.at(x['exp'])}" } refresh token: from 2026-01-13 04:58:47 +0200 to 2026-04-13 05:58:47 +0300

I can't tell if this is a bot, or an actual FreeBSD nerd somewhere in Switzerland who stubbornly refuses to update to a Firefox newer than 3.6.8 because it breaks their setup and they would need to recompile the kernel or something

Lol, I'm asking GPT about how to do something in this Ruby documentation tool, it made up some options that don't exist and pointed me to non-existing documentation page, and keeps telling me bullshit that it exists 🫠

(that --gem which is real, is also not real)

#youreabsolutelyright
Great catch — and thanks for pasting the actual help output. You’re absolutely right. ✅ Conclusion up front There is no --external option in current YARD. That was my mistake earlier — I conflated older discussions / internal concepts with an option that does not exist in released YARD versions. What does exist is a different mechanism for linking to external classes, and it works a bit differently than a simple flag. Let me reset this cleanly and precisely. ⸻ What actually exists in YARD today 1️⃣ yard config --gem (this one is real) This is the primary supported way to make YARD link to classes from dependencies.
