资 源 简 介
This library generates a C# parser for a language encoded into a Parsing Expression Grammar (PEG) along with optional semantic actions. The parser is implemented as a back-tracking recursive descent parser with memoization (i.e. a packrat parser) so it runs in linear time. The library has the follow advantages and disadvantages:
+The language to be parsed is written using a PEG which provides an especially nice syntax for encoding languages (see the example below).
+Parses are unambiguous: if a string parses then it has exactly one parse tree.
+There is no need for a separate tokenization step.
+The library makes it very easy to add semantic actions.
+The library has good support for customizing error messages.
+The library offers a lot of support for customization.
-The library does not support left recursive rules.
-The amount of memory used is proportional to the input size.
-Not a lot of time
