  • Fixing Left and Mutual Recursions in Grammars
    2 projects | news.ycombinator.com | 2 Feb 2025
    Debugging a complex PEG is a nightmarish task. I use various tools, but I couldn't find anything out there that will let you set a breakpoint in a file that's being parsed and let you explore the parsing state.

    The most useful tools I found were adjacent to the cpp-peglib library: https://github.com/yhirose/cpp-peglib

    This comes with a PEG playground: https://yhirose.github.io/cpp-peglib/

    I really liked pegdebug: https://mqnc.github.io/pegdebug/

    With sample output here: https://mqnc.github.io/pegdebug/example/output.html

    pegdebug is nice for small sets of data, but it rapidly gets swamped by anything over about 50 lines.

    If anyone has other suggestions for debugging PEGs, please reply and let me know,.

  • A Good Tool for Resuming Parsers?
    2 projects | /r/cpp_questions | 2 Jan 2022
    Most of the research into this sort of incremental and differential parsing unsurprisingly looks to be in the Haskell community, but I was hoping that someone here might know of some C++-friendly tools that might support generating parsers that support interruption and resuming. cpp-peglib looked really promising, but its parsers don't look like they can be engaged from any but the initial state.
