<div dir="ltr">Hi,<div><br></div><div>I made something like that in the past, but with gccxml, and I more or less achieved the same thing with pyclang.</div><div>I made a free function called encode() and a decode() for usual data types, and then I use my small script (<a href="https://github.com/mbrucher/clang2xml" target="_blank">https://github.com/mbrucher/clang2xml</a>) to help me generate a encode(const MyClass&) decode(MyClass&) that calls the appropriate encode and decode functions, depending on what I scanned. In my case, I also added wrappers for each public function (which actually was my main goal, clang2xml is not as advanced as what I did in the past <a href="http://matt.eifelle.com/2009/07/21/using-gccxml-to-automate-c-wrappers-creation/" target="_blank">http://matt.eifelle.com/2009/07/21/using-gccxml-to-automate-c-wrappers-creation/</a> ), but you can keep it simpler and only serialize and unserialize your data.</div>
<div>With both libclang and the steps I used with gccxml, I think you will be able to achieve your goal ;)</div><div><br></div><div>Cheers,</div><div><br></div><div>Matthieu</div><div><br>

<div> int i;</div><div> string s;</div><div> A obj;</div><div> };</div><div><br></div><div>==>Transform it as below</div>

<div>With the tutotials around i could setup the compiler instance<br></div></div><div>and ASTConsumer and ASTVisitor/</div><div>In the ASTRecursive visitor... i could overload visitRecordDecl(...);</div><div>
On getting a CXXRecordDecl...i have iterated through FieldDecl</div><div>Now From FieldDecl...i want to extract information like</div><div>it is map made from int and string...</div><div>Am not able get the relationship of FieldDecl to CTemplateDecl...</div>
<div>and from CTemplateDecl how to extract the params?</div><div><br></div><div>Pls provide direction how to proceed further...</div><div><br></div><div>regards</div><div>ragha</div></div>
