Rouge VS glimmer-dsl-libui

To see if a particular language is supported you can use Rouge's handle tool rougify. First install a ruby interpreter. Then checkout the rouge source code and run bin/rougify list in the source code root directory:

But... it seems like so many programs were written without this rudimentary check on. Consider this example. I installed Rouge, the well regarded syntax highlighter. Here's some basic code, almost copied directly from their github page:

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! 🤔

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.

glimmer-dsl-libui is a more actively maintained alternative

Another GitHub Pull Request for Rubio-Radio (open-source Internet radio app built with Ruby) got accepted and merged, which focused on displaying the currently playing song/program, loading all available radio stations (instead of a pre-defined limit), and enhanced full-text-search support including column-specific queries. The changes have been released in rubio-radio gem version 0.0.6. In fact, the enhanced full-text-search support is included in the latest version of Glimmer DSL for LibUI (Ruby Desktop Development GUI Library used to build Rubio-Radio) as part of the refined_table custom control for use in any projects, so software engineers get that feature for free now.

Recently, I blogged about how I contributed Pagination/Filtering support to Rubio-Radio, an Internet radio application built with Ruby and Glimmer DSL for LibUI.

I am particularly impressed by the fact that the developers of those apps fully went the distance by walking the walk, not just talking the talk, especially given that the developers of the first app (RubyCrumbler) were brand new to Glimmer DSL for LibUI and had to exercise great problem solving skills to finish their app on time for their needs.

Glimmer DSL for LibUI (Prerequisite-Free Ruby Desktop Development GUI Library): this gem just won a 2022 Fukuoka Ruby Special Award after getting judged directly by Matz (creator of Ruby) and the Fukuoka Ruby Award Competition Judges! How is that for a Year of The Ruby Desktop accomplishment!!?!

Another reason why this library was created was to address the need for supporting automated declarative drag and drop features in Glimmer DSL for LibUI coming soon (right now, it supports manually implementing drag and drop with area listeners out of the box).
