Question

Hello!

First of all let me thank you for your amazing library and willingness to answer questions 🎉

I am trying to write a parser that looks like this

type Result = { kind: 'BrackedText', text: string } | { kind: 'Text', text: string }

const result: Result[] = alt(
  seq(string('['), letters, string(']')).map<Result>(...),
  i_dont_know.map<Result>(...)
).many().tryParse(input)

And I expect it to parse string "Hey [hello] how are [world] you?" into the following

[
  { kind: 'Text', text: 'hey ' },
  { kind: 'BrackedText', text: 'hello' },
  { kind: 'Text', text: ' how are ' },
  { kind: 'BrackedText', text: 'world' },
  { kind: 'Text', text: ' you?' },
]

Basically I want the entire parser to work so, that it parses pieces of string in between BrackedText as just strings regardless of what they contain. But I am stuck writing i_dont_know parser.

This is a very simplified example. In reality I have several different kind of structures instead of BrackedText which I want to parse. So writing parser takeWhile(x => x !== '[') wont do the trick.

Something like this should work. Click “Run” to see the results.

You could make it faster using a custom regexp for other that matches more characters at a time, but this is the easiest approach.

Yeah, the regexp solution is often difficult, haha.

All I meant was that bread-n-butter is SemVer 0.x, so releases may contain breaking changes. Maybe I will update that text later 😃
