Optional custom functions for regex renderer #148

Closed alanhamlett closed 5 months ago

alanhamlett commented 5 months ago

In some cases we need the ability to run custom code when rendering, more than a regex can do. This adds an optional callback function that when provided, should return true or false on the given input text string. It's backwards compatible with current createRegexRenderer usages, but allows overwriting the regex using custom code to prevent matching when necessary.

Alternatively we can use this method signature, maybe it's better?

matchers: [matcher: RegExp | ((_: string) => boolean), style: StyleOrRender][],

It seems better. Thank you for the suggestion!

Oh... so how can we tokenize the text with the alternative method signature without regex?

I think your first suggestion is OK so anyway I'll merge this PR. Could you send a PR if you found a better way? Thank you!

Released in 0.26.1.

Oops, should have added the regex result too. Adding in #149.
