Un Concurrent de Transformers ? - Transformers

31 Oct 2005

  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
