At the moment I am using the ASTConsumer/ASTVisitor interface. But I
am planing to switch to AST matchers asap.<br>
After scratching my head for a while I found the solution for my
problem. It was just a misunderstanding of the inheritance tree.<br>
<br>
Thanks for your help<br>

your help. Of course I went already through a bunch of
documentation including libtooling.<br>
My tool is performing now the basic setup and can
transform some simple cases.<br>

Do you know by chance how to retrieve the ASTContext from
a ReturnStmt and a FuncDecl?<br>

<div>Generally, if you use AST matchers you'll have the
ASTContext in the callback. What exactly is the problem
you're running into?</div>

<p>Hi everyone,</p>
let's consider the example:
<p><font face="Courier New, Courier, monospace">int
foo(int p) {</font></p>
<p><font face="Courier New, Courier, monospace">
if ( p)</font></p>
<p><font face="Courier New, Courier, monospace">
/* code path#1 */<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
return 0;</font></p>
<p><font face="Courier New, Courier, monospace">
else {</font></p>
<p><font face="Courier New, Courier, monospace">
/* code path#2 */<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
return 1;<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
}</font></p>
<p><font face="Courier New, Courier, monospace">}<br>
</font></p>
<p>1. What is the best solution to get the string
representation of the expression of a return
statement?</p>
<p>2. Because I want to perform some
transformation with return statements I have to
figure out if they are enclosed in a block? <br>
</p>
<p>The example above should be transformed in
something like<br>
</p>
<p><font face="Courier New, Courier, monospace">int
foo(int p) {</font></p>
<p><font face="Courier New, Courier, monospace">
if ( p) { /* <---- */<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
/* do some processing ... */<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
return 0;</font></p>
<p><font face="Courier New, Courier, monospace">
} /* <--- */<br>
</font></p>
<p><font face="Courier New, Courier, monospace">
else {</font></p>
<p><font face="Courier New, Courier, monospace">
/* do some processing ... */<br>
</font></p>
<font face="Courier New, Courier, monospace">
return 1;<br>
</font>
<p><font face="Courier New, Courier, monospace">
}</font></p>
<p><font face="Courier New, Courier, monospace">}<br>
</font></p>
Any hints or pointers are welcome.<br>
<p>Thanks</p>
<p>Marcel<br>
