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 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. -

ANTLR
Parser generator to read, process, or translate structured text
...Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for Hive and Pig, the data warehouse and analysis systems for Hadoop, both use ANTLR. Lex Machina uses ANTLR for information extraction from legal texts. Oracle uses ANTLR within SQL Developer IDE and their migration tools. NetBeans IDE parses C++ with ANTLR. The HQL language in the Hibernate object-relational mapping framework is built with ANTLR. -

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... -

RE/flex lexical analyzer generator
The regex-centric, fast lexical analyzer generator for C++
A C++ high-performance regex library and Flex-compatible lexical analyzer generator with full Unicode support, new indentation anchors, lazy quantifiers, and many other modern features. Accepts Flex lexer specification syntax and is compatible with Bison/Yacc parsers. Generates reusable source code that is easy to understand. Supports fast scanning of UTF-8/16/32 files, strings, and streams. The reflex scanner generator generates clean C++ lexer class code that is thread-safe. Generates... -

OpenDetex
Tool for extracting plain text from TeX and LaTeX sources
Improved version of Detex, tool for extracting plain text from TeX and LaTeX sources. OpenDetex is a program to remove TeX constructs from a text file. It recognizes the \input command. This program assumes it is dealing with LaTeX input if it sees the string "\begin{document}" in the text. It recognizes the \include and \includeonly commands. -

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... -

XML Parsers and Utilities
integrated set of C++ tools for manipulating XML schemas & data files
...The tools are: •xmlSchemaParser - parses and reformats XML schema files, and prints typederivation hierarchies. Also includes a C++ model of XML schema. •xmlInstanceParserGenerator - generates C++ classes and a YACC/Lex instance file parser from an XML schema – it’s a software tool that writes software tools •orphanFinder - identifies unused types and undefined types in one or a set of XML schema files •xmlSchemaAttributeConverter - rewrites an XML schema file, converting attributes to elements •xmlSchemaXpathChecker - checks that all paths in all constraints in a schema are possible, and reports those that do not exist •xmlSchemaPathFinder - generates all possible paths through an instance tree that contain components specified by the user -

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 :-). ... -
