    PHP Parser

    PHP Parser

    A PHP parser written in PHP

    ...A parser constructs an Abstract Syntax Tree (AST) of the code and thus allows dealing with it in an abstract and robust way. As the parser is based on the tokens returned by token_get_all (which is only able to lex the PHP version it runs on), additionally a wrapper for emulating tokens from newer versions is provided. This allows to parse PHP 7.4 source code running on PHP 7.0, for example. This emulation is somewhat hacky and not perfect, but it should work well on any sane code. Support for pretty printing, which is the act of converting an AST into PHP code. ...

    Ox: Attribute Grammar Compiling System

    Ox: Attribute Grammar Compiling System

    Ox is an attribute-grammar evaluator generator.

    Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees. The user can specify parse-tree traversals for easy ordering of side effects such as code generation.

    SCons

    SCons

    A software construction tool

    SCons is a software construction tool that is a superior alternative to the classic "Make" build tool that we all know and love. SCons is implemented as a Python script and set of modules, and SCons "configuration files" are actually executed as Python scripts. This gives SCons many powerful capabilities not found in other software build tools. We make SCons available in three distinct packages, for different purposes. - The scons package is the basic package to install SCons. You...

    LR Parser and Lexer Generators: Fortran

    LR parser generator and lexer generator for use in Fortran

    The generator for LR parsers uses Pager's method, augmented with Tom Pennello's Forward Move Algorithm for error recovery. The grammar specifies identifiers for nodes in the abstract syntax tree, and the identifiers for tokens. It generates Fortran declarations for tree node identifiers and named constants that represent the PDA. The lexer generator accepts regular expressions and generates a DFA. It generates Fortran declarations for character classes, recognized objects, named constants...

    NaiveLanguageTools

    C# lexer and parser

    NLT is free, open-source C# lexer and GLR parser suite -- which translates to ability to parse ambiguous grammars. Grammar can be defined directly in code or (preferably) in separate file (lex/yacc-like) for included generator. If you understand/guess the meaning of grammar in C#: // scanning lexer.AddStringRule(")", match => SymbolEnum.RPAREN); // parsing prod_builder.AddProduction(SymbolEnum.exp, SymbolEnum.LPAREN, SymbolEnum.exp, SymbolEnum.RPAREN, (_1, e, _3) => (AstNode)e); or grammar in NLT format: // scanning /[A-Za-z_][A-Za-z_0-9]*/ -> IDENTIFIER, IdentifierSymbol.Create($text); // parsing program -> list:namespace_list { new Program(currCoords(), (Namespaces)list) }; you should be able to use it :-). ...
