Ruby and parsing


#1

Hi all,

Firstly, Happy New Year :stuck_out_tongue:

Secondly, I have a c++ source code with many “try catch”.

try {

}
catch (Exception &pException) {
<BODY OF CATCH (for Exception)>
}

I would like to parse my file and add a ‘catch’ with std::exception
automatically,
to get the next example.

try {

}
catch (Exception &pException) {
<BODY OF CATCH (for Exception)>
}
/// New catch added by a ruby script.
catch (std::exception &pException) {
<Fill the body of this catch with the body of catch (for Exception).>
}

How can I do it ? Because I find some problems :frowning:

  1. Try to parse a lot of line with Regexp.
  2. In the body of a ‘catch’, it can contains brackets

Best Regards,

Stephane

I don’t think Regexp is a viable alternative for this one - you might
want to implement a trivial recursive-descent parser for C++, counting
the opening and closing brackets after each catch clause. Unless the
bodies of the exception handlers contain unmatched brackets in strings,
that should work.

Thanks David,

I will try this solution during my week.
