Plex: a parser and lexer generator as a Rust syntax extension

• therobot24 11y ago
  Probably want to choose a better name seeing as plex.tv is pretty well known. Or maybe it's named to be confusing, "I built Plex", i dunno
  • higherpurpose 11y ago
    Indeed, I thought the Plex guys started using Rust.

  Not to be confused with the media server. Come on, pick a better name.

  Plex = media server, noob

  So, just to clarify...is this a port of the venerable Python lexer generator called Plex? https://pypi.python.org/pypi/plex/ https://pypi.python.org/pypi/plex/

  Unless you are Greg Ewing, you should probably choose a new name.

  Rename it to parl

  The C comment example seems more simply solved using non-greedy matching. Is that not done because the parser absolutely does not support non-greedy (or minimal-munch) matching?

    The parsing of C-style comments is a sort of standard example to demonstrate some additional features you have available when your lexer-generator is implemented using regular expression derivatives. See section 5 of "Regular Expression Derivatives, Re-examined" for details: http://www.mpi-sws.org/~turon/re-deriv.pdf http://www.mpi-sws.org/~turon/re-deriv.pdf

  There's also rustlex [1] that have been around for a while and provides rust stable v1.0 support through syntex [2]. I use it for a handlebars implementation [3].
