Matching a regex partially can lead to generating a token which causes the whole generated sequence to be invalid.
When using partial=True, we ensure we don't generate invalid output, but also this makes it impossible to generate certain output sequences. Therefore it's necessary to allow generating tokens which match only partially, and then take the substring of that token which matches the regex.

I'm interested in this solution too, as I was having the same parserllm issues as in: r2d4/parserllm#4 Also, the outlines project may interest you. They precompile valid continuations, and then inference happens in The issue I have with |

Matching a regex partially can lead to generating a token which causes the whole generated sequence to be invalid, even if a substring of the token would result in a valid output.
The other option would be to tweak
complete_rewe run theif stop_after_match:block after every character of the token (rather than the full token text) to the output text, but that's less clean. Or is that needed to be able to generate some output sequences which can only occur by generating a larger invalid token and then pruning the output?Edit: looks like we need the latter approach, see latest commit.
