You might be interested in Ohm's incremental parsing support. I'll be presenting a paper on this at SPLASH next week: https://ohmlang.github.io/pubs/sle2017/inc

You might be interested in Ohm's incremental parsing support. I'll be presenting a paper on this at SPLASH next week: https://ohmlang.github.io/pubs/sle2017/incremental-packrat-parsing.pdf https://ohmlang.github.io/pubs/sle2017/incremental-packrat-p.... In theory, what you're suggesting should be possible to implement with our incremental packrat parsing algorithm. But we haven't tried it yet, so I can't say for sure.
