C0DATA — Structure Data with Control Codes

You're looking for something that's readable but more efficient and smaller than #JSON or #YAML?
Structure data with #ASCII control codes like people did in 1963!

https://trans.github.io/c0data/

There's also a library in @CrystalLanguage available.

GitHub - rvprasad/advent-of-code-2025: Advent of Code 2025 repo solutions in Crystal, Elixir, Rust, and Scala Advent of Code 2025 repo solutions in Crystal, Elixir, Rust, and Scala - rvprasad/advent-of-code-2025

For #adventofcode 2025 problems, I cycled through #crystallang, #elixir, #Rust, and #Scala -- each problem in two languages. Looking back, I enjoyed working with Elixir (followed by Scala). I think the pipe operator was a big factor as it simplifies data processing.

Claude Code made significant progress since last night (85%!), all pushed to the repo: github.com/luislavena/j...

Now asking to convert run_tests runner to proper crystal spec (using macros): gist.github.com/luislavena/5...

Following @simonwillison.net test of porting JustHTML to another language, decided to task Opus 4.5 and port it to #crystallang, been running for 2 hours, ran out of context space 1 time, but looks promising.

The only thing that makes this worse is that compiling #CrystalLang takes nearly 45 minutes now for production. So missing some runtime bug means nearly an hour before it's fixed. This is why #Lucky focuses on development compile catches.

It takes me 2 minutes and 21 seconds to run a single spec in #CrystalLang. The actual spec completes in 145 milliseconds. Absolutely brutal for productivity 😫 Hoping this drops once I can delete some old files.

Main blocker is the #CrystalLang, the game is written with Crystal and Raylib, which means it can build into everything that both Raylib and Crystal supports. it seems WebAssembly is not yet a supported target in Crystal.

Just released Rosetta v1.0.0, an #i18n shard for #CrystalLang, about four years after its inception. Aside from a some QoL improvements it now also supports key nesting, a feature that was on the wishlist for a very long time.

Is so much fun watch Claude Code implement some features when your feedback cycles are really fast. Thank you #crystallang for that 🚀

After 3 months I had to restart a #crystallang service because it was eating too much memory! 52MB! Outrageous! Thankfully now it's back to it's regular memory usage!😅
