Project Status

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

Feature Status
Lexer and Parser mostly complete. there are probably a few gaps still
Scoping complete for simple cases. probably some gaps still, most notably that conditional definitions are treated as if they are always defined
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 basic idea implemented, need follow through with more node types
Type inferencing not begun
Dead code analysis basic idea implemented, but only for some types of code. Also, this suffers from the same caveats as scoping

Project Components

Directory Description
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/parser the core parser
php/passes tools and packages related to modifying or analyzing PHP code (heavily a work in progress)
php/passes/togo transpiler
php/passes/deadcode dead code analyzer
php/query tools and packages related to analyzing and finding things in PHP code (heavily a work in progress)
php/testdata simple examples of PHP that must parse with no errors for tests to pass
php/token describes the tokens read by the lexer
