Je me promenais sur comp.lan.c++.moderated quand je suis tombé sur ce thread (cf ci-dessous) qui devrait intéressé quelques Transformeux. Je n'ai jamais entendu parler de Semantic Designs auparavant, mais ce n'était peut-être pas votre cas... Malheureusement ce n'est pas du libre, mais je me demande quand même si ils font réellement tout ce qu'ils annoncent ?

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?
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. See the DoD Crosstalk article on automate C++ component reengineering at http:°www.semdesigns.com/Company/Publications/CrosstalkArticle/Crosstalk-05-2005.html
