The @roc_lang track is live on @exercism_io! Exercism is a fantastic platform for learning programming languages and I'm very happy to say that Roc is now part of it. To mark the occasion I wrote a blog post about one of my solutions: isaacvando.com/roc-exercism-…

Here's something useful! Pure Roc implementations of: ⭐️SHA-256 ⭐️HMAC-SHA 256 ⭐️Base64 ⭐️Hexadecimal strings github.com/quelgar/roc-utils (Security note: these aren't trying to be resilient to timing attacks, so only use them for use cases where timing attacks aren't a concern!)

Someone at #sycl24 was just talking about organizing a @roc_lang conference in Côte d'Azur in the next year or so...if that existed, would you want to attend? 😃

For anyone wanting to write @roc_lang code in Neovim, it's quite straight forward to get the language server connected up. See this Gist for details: gist.github.com/ChrisWellsWo…

Thanks to Alf Richter for creating a Roc extension for @zeddotdev - it has both a language server integration and tree-sitter grammar for syntax highlighting! github.com/h2000/zed-roc
