CodeWorker - A parsing tool and a source code generator works on generative programming. It offers facilities for building a DSL, for generating code, for source-to-source translation or program transformation, for driving the automation process. [Open source, LGPL] AutoGen - A tool designed for generating program files that contain repetitive text with varied substitutions. This is especially valuable if there are several blocks of such text that must be kept synchronized. [Open Source, GPL] Somusar - Allows generate software source code files (Java/SQL, PHP/mySQL, C#/ASP) base at data structure and data values in .ef (internal Somusar format) and XML files. Objective Systems - Provides code generation tools that can generate C/C++, Java, C# code from ASN.1 (Abstract Syntax Notation 1) or XML schema specifications. CodeSmith - A freeware template-based code generator that can generate code for any ASCII-based language. CodeSmith templates use a syntax nearly identical to ASP.NET syntax so that creating templates should feel immediately familiar to ASP.NET developers. Graphical Source Code Editors - Some details (block, code formatting, optimizing) of such editors, HTML as example, with reader comments. Smart Software. MetaL - Metaprogramming Language, XML based source code; compiler engine can emit same program from MetaL source code to any supported target language, now Java, Perl, PHP; add others any time. Also home of Metastorage, program automatically emits code from a high level data model definition.
