With regards to the HTML option of notextile as described here:

https://textile-lang.com/doc/no-textile-processing

How should I fix that? Do I just put a match in the "html" context and after <notextile> tag push to plain text and pop before closing </notextile> tag?

[michaelblyons]

For <notextile>, I am perhaps not the most qualified person to weigh in, but I expect embed of HTML is best to ensure escape at arbitrary locations. I think one question after that is whether you feel very strongly that you want to clear all scopes or whether text.html.textile ... text.html.plain is okay.

[jrappen]

I understood that it should be plain text between the "notextile" HTML tags.

⚠️ FYI: Current status of the syntax performance while testing with the updated test file.

Syntax "Packages/Textile/Textile.sublime-syntax" took an average of 1.3ms ±0.0ms over 10 runs
    minimum: 1.2ms, maximum: 1.3ms

NEW

Syntax "Packages/Textile/Textile.sublime-syntax" took an average of 1.7ms ±0.2ms over 10 runs

Not sure why transforming symbols doesn't work as expected. Will check again later.

Scopes are fine.

Seems to add whitespace I prepend fine, also seems to extend the symbol region by the amount of characters added as whitespace towards EOF. Only does for globals (indexed symbols). Weird.
