In the web editor for x86-64, the Ctrl+/ shortcut for commenting out a line inserts the wrong character. The # character is inserted, but the symbol for comments is ;.
This is due to https://github.com/codemirror/legacy-modes/blob/48c56cf79a883068880ba24efc053c1413bb8df0/mode/gas.js#L130
Ideally - using nasm as a backend - we should be using our own nasm module instead of relying on gas.
There’s one I see - GitHub - converge/brackets-nasm-syntax-highlighter: Brackets editor NASM syntax highlighter - 8 years old.
