1-st Pop-Up Menu Builder allows you to create a customized menu which pops up when pressing the right mouse button on a Web page. The customized menu can be applied to a whole page or to specific elements on the page. A wide variety of actions can be set to the items in the menu.
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.
AMC is a programmable compiler/preprocessor. It has a built-in programming language called CGL (Code Generation Language) that lets you add new syntactical elements to the source files that AMC processes. In addition, AMC has a module structure reminescent of the UCSD p-System compiler. AMC comes with a default package that adds a dynamic form of OOP to C.
APRIL is a symbolic programming language that is designed for writing mobile, distributed and agent-based systems especially in an Internet environment. It has advanced features such as a macro sub-language, asynchronous message sending and receiving, code mobility, pattern matching, higher-order functions and strong typing. The language is compiled to byte-code which is then interpreted by the APRIL runtime-engine. APRIL now requires the InterAgent Communications Model (ICM) to be installed before it can be installed.
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.
