  • Syntax highlighting library support for modern frontend frameworks
    2 projects | | 22 Jun 2022
    I was going to write a post about Svelte and I was checking if it is a language that is supported by the highlighting library I use (Rouge). It is not! I guess I could fudge it by using HTML as the language for the code blocks because it is HTML-like. Or add a lexer/extension myself! 🤔
  • Glimmer DSL for LibUI Code Area (Ruby Tooling Future)
    2 projects | | 26 Mar 2022
    Brandon Weaver has recently contacted me on the Glimmer Gitter to ask questions about Glimmer DSL for LibUI. He also mentioned the node pattern tool written by Marc-André Lafortune (a fellow Rubyist I know in Montreal), which is hosted on Heroku. Brandon said he was excited about the possibility of implementing something similar in pure Ruby using Glimmer DSL for LibUI by leveraging the rouge syntax highlighting gem. He has even blogged about the Ruby Tooling subject in the past with the title "Future of Ruby - AST Tooling", which Matz (creator of Ruby) has alluded to before.
