I'm looking for a tool to simplify program manipulation. I need something that parses C++ into a tree format, INCLUDING the comments and line breaks, and which can also turn that tree format back into source text. The parse tree must identify the syntatic elements of C++, with function calls and type declarations correctly parsed. Ideally, the parser would generate the tree as an XML file, for ease of handling. But that's optional. The idea is to allow writing simple tools that check or modify declarations and function calls to add some safety checks. Does anything like this exist?

I don't know whether one exists, neither searched for one. You want something special, I think. Because how would you build a tree from C++ source? If you need something like UML, there are ULM-to-XML converters. But most (AFAIK) UML applications do not like C++ at all. (I guess, Rational Rose is exception) I guess you need something more like a lex-yacc work, write your very own parser, translator.

Not exactly what you are thinking of, but you can probably add the remaining features to GCC-XML, seen at: http://www.gccxml.org/HTML/Index.html I think this is a very worthwhile idea and project.

I think all C++ compilers represent the program in trees at some point of compilation. If you can't find an existing tool maybe you can try to tweak a (open source) compiler to do so. ben [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

There is also http://www.gccxml.org/HTML/Index.html although I believe that the bodies of functions may not be represented. Thanks. Both look promising, although neither is really finished yet. Synopsis, in particular, will tear apart code, keep the comments, produce a parse tree, and retain enough info to regenerate the source. Almost. I'll have to see how well it works.

The idea is to allow writing simple tools that check or modify declarations and function calls to add some safety checks. Does anything like this exist? Yes. Translating C++ into some kind of XML schema has been the subject of several research projects at various universities in recent years. There is little consensus about which parts of a C++ program should be captured in the XML; some translate only declarations and not definitions, for example. There have been attempts to formulate a standard XML schema to describe a C++ program, but issues like the preprocessor and inline assembly language complicate the representation. I believe more research is probably needed in this area. The only tool that I am aware of that preserves comments and identation of the C++ source files is srcML, which is an open source tool available at this link: http://www.sdml.info/projects/srcml/ Greg [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Hi, Check Columbus/CAN at http://www.frontendart.com It is free for academic purposes. There are various export formats including XML. Columbus is capable to parse large input files, and as I now it fullfils the requirements you wrote.

See http://www.semdesigns.com/Products/FrontEnds/CppFrontEnd.html This is a C++ front end built on top of DMS, general-purpose program transformation machinery, and is offered as an industrial strength commercial product. It has a full C++ preprocessor and parser (for most commonly used dialects including ANSI, GNU, and the various MS dialects), automatically builds trees as it parses, capturing comments and lexical formats (indentation, number radix, ...) and builds a full symbol table. It makes those trees/symbol table available to custom code you write to accomplish your task, including arbitrary analysis and or serious automated transformation of the code. You can regenerate complete source text from the trees, including preprocessor directives (with some limitations) the comments and other lexical formats as undisturbed, or programmatically change that lexical information. A trivial custom task is to call the XML export function in the supplied AST management API to dump out the tree as XML ;-}. While you can do this, when you discover how big trees are, you may find this isn't the best option, especially considering that DMS provides extremely good facilities for transforming trees. This tool has been used for massive C++ source-to-source transformations.

If what you want to do is get a syntax tree, perhaps. That isn't really very useful. If you want to actualy *transform* the application in any interesting way (e.g., the tasks outlined above), you need full name and type resolution, because the transforms will be conditional on the types of entities they transform. -- IDB [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
