>>You do have a way (ss attached): a list of files names to skip
Right, but the .c files are variably named depending on the obfuscation/decomposition applied.
>>Wildcards support would be desirable.
Yep. Although VFP Compiler allows C++ and ASM files to be inlined into your prg so they're VFP applicable now, I'm not sure you'd be using Gofish to search a .c file generated as a byproduct of obfuscation and that is meant to be hard to follow. There are other (better) debugging options.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
