language - A fast PEG parser written in JavaScript with first class errors

  •    Objective-J

Language.js is an experimental new parser based on PEG (Parsing Expression Grammar), with the special addition of the "naughty OR" operator to handle errors in a unique new way. It makes use of memoization to achieve linear time parsing speed, and support for automatic cut placement is coming to maintain mostly constant space as well (for a discussion of cut operators see: www.ialab.cs.tsukuba.ac.jp/~mizusima/publications/paste513-mizushima.pdf). The most unique addition Language.js makes to PEG is how it handles errors. No parse ever fails in Language.js, instead SyntaxErrorNodes are placed into the resultant tree. This makes it trivial to do things like write syntax highlighters that have live error reporting. This also means that Language.js is very competent at handling multiple errors (as opposed to aborting on the first one that is reached).

Ragel lexer and Bison parser integration example

This a sample of win(bison) parser and Ragel lexer integration, with unicode support

simple_wc_example - simple word count example using flex/bison parser

  •    C++

Between the tutorial and the code you should be able to get started with more advanced projects using C++ and Flex/Bison. Admittedly the example itself is a bit contrived, however it's mean to be simple and get the point across. If there are changes in Flex/Bison that prevent the example from compiling or if you just have improvements, feel free to generate a pull request or just shoot me an e-mail. To compile just download and run make, there's a super simple test harness to make sure it runs in the test dir.

flex-bison-indentation - An example of how to correctly parse python-like indentation-scoped files using flex (and bison)


An example of how to correctly parse python-like indentation-scoped files using flex (and bison). Besides that, this project also serves as a template CMake-based project for a flex&bison parser and includes rules to track the current line and column of the scanner.
