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. Ox handles the tedious and error-prone details of writing code for parse-tree management, so its use eases problems of security and maintainability associated with that aspect of translator development.

GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards (2002, 2014, 2023), as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others). GnuCOBOL translates COBOL into C and internally compiles the translated code using a native C compiler. Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and...

Parse C++ header files using ply.lex to generate navigable class tree representing the class structure. CppHeaderParser.py has the advantage of being a pure python C++ header parser. Grap a copy of ply at http://www.dabeaz.com/ply/

...As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.

Grammar based parsing in Java 8 to a tree structure. Create with no overhead a grammar in java and parse it into a tree structure. Will probably work right away with your grammar.

The fast, flexible parsing engine. Parse anything in 4 steps: (1) define a grammar, (2) load the grammar into ClearParse, (3) call the engine to parse the source, and (4) traverse the parsing tree. You can even change your grammar at run time.

...A simple BNF style language is used to describe scanner and parser in a UTF-8 source file. The output is described with a template language that is used to add formatting to the parse tree. Code is generated that automatically traverses the parse tree and calls a method on a transformer object to modify the parse tree. Each node is visited in document order, and a method is called at the beginning and end of each node visit. This transformer class is subclassed for customization. SimpleCompiler has many built-in feature for supporting a variety of text based language.
