inverted --source-filter

awesome tool!

could we get an inverted --source-filter please? i.e. to exclude stuff from the report.

because it appears to be unreasonably hard to generate a negative regular expression that RE2 will accept.

For example, trying to exclude c++ std library classes:

bloaty -d shortsymbols,fullsymbols --source-filter ^[^s][^t][^d] instdir/program/libsclo.so

Yes I think this is a great idea.

Biggest question is how to specify this on the command line. The first things that come to mind are:

bloaty --source-filter !std

or:

bloaty --source-filter ~std

But unfortunately both of those have special meanings for the shell.

git has --not e.g. see

https://git-scm.com/docs/git-grep#Documentation/git-grep.txt---and

--source-filter-not
or
--not-source-filter

also works for me.

Or convince the RE people to support the perl
?!
operator :-)

+1. I was recently working with bloaty and this is a feature I'm really missing.
