This is a TS-implementation of CommonMark, developed from the JS-implementation commonmark.js.
This uses a compiling mechanism, i.e., compile while editing. It finds the smallest dirty node, and recompiles that node only, reusing unrelated nodes within the dirty node. So it is very efficient for editing.
cd /path_to/commonmark.ts/src/test
deno test --allow-read --allow-net # 779 steps
Using Deno 2.1.10 causes "segmentation fault" in one-line error message! (#25192)
Downgrading to 1.45.5 (deno upgrade --version 1.45.5
) works fine.
