<p class="MsoNormal">Hi, all.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I'm writing some tools to convert a C++ class to something else, and I want to add some custom information to the AST.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">At first, I decided to add some comments to mark some classes, but I found that the AST does not contain comments.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Secondly, I want to customize an attribute, but I found that it needs to recompile the Clang, I didn't find a "plug-in" way. Since my tools are designed for public usage, a customized compiler is not very considerable.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Currently I have to force the user to declare their class names and field names with some special rules, but this is not very acceptable to me.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So anyone knows if there's a better way to add some custom information to the AST?<o:p></o:p></p>
