You can pretty much use any language that can build a parser for each of the
languages you want to do that for. I used a program called 'cscope' which
did something like that for C. You could type in a symbol and what you were
specifically looking for (definition, prototype, instance, etc.) and it
would search an entire directory structure for it. Your problem however is
far more complicated since you want it to apply to multiple languages.
Therefore, you would basically need a builtin parser for EACH language. I
would recommend getting the source code to one of the newer editors such as
the 'vim' that comes with Linux. This tool changes the color of your text,
depending on what type of file you are editing. It seems understand quite a
few languages and does a surprisingly good job. So far, it's worked on
HTML, C, Perl, C++, shell scripts and .conf files.
