> It also looks like this adds some new functions to some base files - won't those potentially break other tree-sitter grammars? The changes introduced to core don't change how...

Thanks! I'll revisit this when I get a chance; I got the new runner close to feature parity with the old one, but I should take another pass at it....

~~The visual test runner is failing on most of Pulsar's core tests. Notably, it seems like it's not mocking methods that (e.g.) spawn a file dialog, so those dialogs appear...

OK, after installing new modules and relaunching Pulsar, most of my problems go away… except that the runner does still crash. I don't think it's failing on a specific test,...

I drilled into it; it's crashing [on this line](https://github.com/pulsar-edit/pulsar/blob/master/spec/decoration-manager-spec.js#L9).

OK, it's also failing on `master` when I run the specs from the terminal: ``` dyld[62991]: missing symbol called Renderer process crashed, exiting ``` This is troublesome, but it seems...

I've gotten reasonably far here. But the crashing issue I described above — though it's unrelated to this PR — throws a major wrench in my ability to assess this...

@Atelier-Mirai [has reported](https://github.com/pulsar-edit/pulsar/issues/867) an occasional failure in Markdown parsing when typing Japanese text. This issue is broadly understood, but I'd love to get some specific reproduction steps, particularly if it's...

_I meant to post this explanation in here, but inadvertently put it in #867. Let me try again._ So I'll try to summarize the problem for anyone who might be...

~~@luixxiul noted in #885 that `tree-sitter-markdown` fails to detect URLs in certain circumstances, and I'm not surprised that multibyte input seems to be present in this issue as well. Meanwhile,...
