scanner-attoparsec: Inject attoparsec parser with backtracking into non-backtracking scanner
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
Warnings:
- 'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
Backtracking kills performance, so scanner package doesn't support it. But sometimes you just need it. E.g. you have a mostly non-backtracking parser, but a small bit of its grammar is too complex to transform it to non-backtracking form. In that case you can inject a backtracking attoparsec parser into otherwise non-backtracking scanner.
