The format style is hardcoded to Prettier + Svelte's config which uses trailingComma:none ... save tokens! Svelte formatting also respects version 5's HTML-diverging whitespace trimming rules, making common warty cases readable (a bigger motivation for starting this project than I'd like to admit)

tsv turns 1 year old at the end of the month. I originally published with a squashed history, but it now includes 47 commits condensing the pre-release history. It's my first serious LLM-generated project, and the benchmarks appear to justify the effort. I'll blog about it soon.

The project is still rough in spots, but it also fixes numerous bugs in the reference tools. The repo documents many bugs and quirks observed in Prettier, prettier-plugin-svelte, acorn-typescript, and Svelte's parser. I submitted some fixes this year, and there's a lot more I want to contribute.
