Hello James,<br>
<br>
Thanks a lot for your help and sorry for my late reply. Your information is
helpful, however what I want to know is the main method of clang that calls the
printpretty() function. As you mentioned, lets have S
->printpretty(context). We can see this at StmtPrinter.cpp class as I
mentioned earlier. My question is which main method of clang this function is
called. As we know at run time there is at least on main method that calls
other functions. Assume we want to print the source code of AST. We will run
clang on command line. we will use a command(I don't know the command) that
calls the print pretty function. Hope you get my idea. So, which main method/function
of clang is calling this function? Thanks again.</span><u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Georgia","serif";color:#330099"> Hello All,<br>
<br>
Clang has a number of classes and functions inside its implementation. Most of
the time it makes me to be confused to identify the interconnection among
classes and functions. Because many functions may be called from different
header files. The main thing what i want to know is about main methods of
clang. I have seen 4 main functions in clang. But it is difficult for me to
identify in which main methods are other functions called. To make it clear let
me talk about one class(example StmtPrinter.cpp class). This class prints back
source code from AST. Under this class their are two functions i.e
PrintPretty(..) and DumpPretty(..). Suppose I want to use printPretty(..) and
it is called at different functions. Where is the main method of clang
that calls this function to print the source code? Can someone tell me how it
works. I tried to greped out on command line but failed to get the main method
that calls this function. Even I want to know the command to use this function.
<br>
<br>
Sorry, it might be silly question, but I failed to get it out. Thanks in
advance for your help!.</span><u></u><u></u></p>
