An incremental parsing system for programming tools
Tree-sitter is a parsergenerator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. General enough to parse any programming language. Fast enough to parse on every keystroke in a text editor. Robust enough to provide useful results even in the presence of syntax errors.
This project has moved to GitHub ! The version here at SourceForge will remain for historic purpose.
Koopa is a parsergenerator, made for COBOL. It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.
JetPAG is a recursive-descent parser and lexical analyzer generator focused on high efficiency, usability and readability of generated code. JetPAG generates fast recognizers and aids developers with useful tools for simplifying input interpretation.
