MaxPC is capable of +parsing deterministic, context-free languages, provides powerful tools for +parse tree transformation and error handling, and can operate on +@dfn{sequences} and @dfn{streams}. It supports unlimited backtracking, but +does not implement @url{http://pdos.csail.mit.edu/~baford/packrat/thesis/, +Packrat Parsing}. Instead, MaxPC achieves good performance through its +optimized primitives, and explicit separation of matching and capturing input. +In practice, MaxPC parsers perform better on typical computer languages—when +compared to Packrat parsers—at the expense of not producing linear-time +parsers.") + (license license:agpl3)))) + +(define-public cl-maxpc + (sbcl-package->cl-source-package sbcl-maxpc)) + +(define-public ecl-maxpc + (sbcl-package->ecl-package sbcl-maxpc)) |
