I wrote a code based on libtooling to add a simple printf in each IF statement as follows:
```cpp
bool VisitIfStmt(IfStmt *If) {
FullSourceLoc FullLocation = Context->getFullLoc(If->getBeginLoc());
if (FullLocation.isValid()) {
if (Stmt *Then = If->getThen()) {
SourceLocation StartLoc = Then->getBeginLoc();
SourceLocation EndLoc = Then->getEndLoc().getLocWithOffset(1);
IfCounter++;
std::string NewIfStmt = "";
// Check if the body is a compound statement
if (isa<CompoundStmt>(Then)) {
NewIfStmt += " printf(\"Executing code block " + std::to_string(IfCounter) + "[\\n\](file://n/)");\n";
NewIfStmt += TheRewriter.getRewrittenText(SourceRange(StartLoc, EndLoc));
} else {
NewIfStmt += "{\n";
NewIfStmt += " printf(\"Executing code block " + std::to_string(IfCounter) + "[\\n\](file://n/)");\n";
NewIfStmt += TheRewriter.getRewrittenText(SourceRange(StartLoc, EndLoc));
NewIfStmt += "\n}";
}
NewIfStmt += "\n}";
TheRewriter.ReplaceText(SourceRange(StartLoc, EndLoc), NewIfStmt);
}
}
return true;
}
```
However, for this target code:
```cpp
int main (){
int a = 1;
if (a == 1)
if (a > 0)
return true;
}
```
It will be changed into
The `return` is incorrectly split.
