Parser for PHP written in Go

See this post for an introduction.

Test console:

This project is under heavy development, though some pieces are more or less stable. Listed here are components that in progress or are ideas for future development

• Lexer and Parser: these pieces are quite useable and haven't seen more than minor changes for a while. They do have notable gaps, though (e.g. namespaces).
• Code search and symbol lookup: basic idea implemented, many many details missing
• Code formatting: basic idea implemented, formatting needs to narrow down to PSR-2
• Transpilation to Go: not begun.
• Scoping: not begun.
• Type inferencing: not begun.
• Dead code analysis: not begun.

• php: the core parser
• php/ast: (Abstract syntax tree) describes the nodes in PHP as parsed by the parser
• php/ast/printer: prints an ast back to source code
• php/cmd: a tool used to debug the parser
• php/lexer: reads a stream of tokens from source code
• php/passes: tools and packages related to modifying or analyzing PHP code (heavily a work in progress)
• php/query: tools and packages related to analyzing and finding things in PHP code (heavily a work in progress)
• php/testfiles: simple examples of PHP that must parse with no errors for tests to pass
• php/token: describes the tokens read by the lexer
