4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.
gtklean is a C header file generated directly from the GTK+ headers to provide a visually cleaner and less error prone C API for GTK+. It eliminates gtk_ prefixes in front of every GTK+ function. It automatically inserts calls to the type checking and casting macros for arguments that require them (e.g. GTK_WIDGET() and GTK_SIGNAL_FUNC()) so you can't forget them and never need to see them. It also replaces the string literals used for signal names with C identifiers to replace run time errors with compile time errors.
ClearParse is a flexible engine that can be used for any parsing task including interpreting or compiling programming languages, analyzing or converting data files, processing command line parameters and user input, implementing markup languages and scripts, natural language processing (NLP), and more.
Genscreen generates C or C++ code using ncurses library functions for building I/O screens. Screen layouts are designed using any text editor (vi, emacs, etc.), then the layout file is run through Genscreen and automatically converted to compilable C/C++ code. Once the basic screen code is generated it can be edited, have additional features added, or be merged with other code. Genscreen also includes automatic date field generation for both US and European date formats, and support for generating money fields.
Gentle is the first compiler construction system that handles the full spectrum from analysis over transformation (AST) to (cost-based) synthesis. Instead of confronting the user with several special purpose languages, Gentle provides a uniform notation for all tasks. It is based on recursive definition and structural induction: the underlying paradigms of virtually all tasks of translation. Rules may be interpreted as grammar rules (lex/yacc), as logical statements, or in a procedural way. Members of a rule may have parameters. This results in attributed grammars.
Memphis is a C/C++ precompiler for compiler writers and other programmers having to manipulate symbolic data. It is well suited for the definition of abstract syntax trees (AST) and the implementation of tree walkers. The Tool extends C/C++ with algebraic types and pattern matching that are known from modern functional programming languages (SML and Haskell).
Accent is a compiler compiler that does not rely on specific subclasses of context-free grammars and that can be used like Yacc. It also cooperates with Lex. Accent supports inherited and synthesized attributes. It allows you to write your grammar in the Extended-Backus-Naur-Form. Semantic actions can be inserted anywhere; there are no restrictions caused by the parser implementation. Accent even allows ambiguous grammars with much less effort than with traditional LALR or LL compiler compilers. An annotation framework has been developed to resolve ambiguities. It is on the abstract level of grammars and does not reflect the parsing algorithm. Moreover, this calculus is complete in the sense that it can handle each ambiguity in any grammar.
Cocom is a toolset that is oriented towards the creation of compilers, cross-compilers, interpreters, and other language processors. It consists of reusable packages (collection and memory management framework), a Sprut internal representation description (AST-to-AST) translator, a Nona code selector description translator (generator generator similiar to BEG, Twig, Burg, and Iburg), an MSTA syntax description translator (yacc-compatible parser with better error reporting), an OKA pipeline hazards description translator, and SHILKA keywords description translator (similiar to gperf but faster).
