Re^2: regexp for finding all function calls

Ok.

I have a large code base of say thousands of perl files. I want to copy all calls to Mod::func() interspersed in these thousands of files to a single file, say funcCalls.pl. Then I will run fucCalls.pl and verify the output of all of the calls to Mod::func().

If the output is wrong, hopefully I will have recorded the line number and file from which each call to Mod::func() came from. In this way I will be able to fix any erroneous calls to to Mod::func().

I'd recommend using PPI, which does its best (and a very good job) at actually parsing Perl. You can search through the parse tree for sub calls, and check their names. That will be much more accurate than anything you can achieve with a regex.	[reply]

Ok, thanks. Do you have any good examples for me to look at? Would I be using PPI::Statement::Expression?	[reply]

I haven't done much with PPI, but I know that Perl::Critic uses it extensively, so in the source code you'll find many usage examples. There are also some examples exaxmples here on perlmonks. Searching helps.	[reply]

By the way, that was my post above as Anonymous Monk, I forgot that I wasn't logged in.	[reply]
