Deleting commented-out code [message #256864]

Does eclipse have a built-in function I can use to mass-delete
commented-out code, without removing programmer comments?

It seems like this should be doable in a couple of ways, but I don't
have the time to work on it myself, at least not right now...

You could use find+replace (CTRL-F or CTRL-H) to search thru files and
make regexp-based matches, then replace them with "".

Or you could pipe the file thru perl and do line replacements that way...

cat somefile.foo | perl -pe "s#//.+##g" > somefile.foo.out; mv -f
somefile.foo.out somefile.foo

It seems like either one of those would leave blank lines in place of
commented lines, but it's a start...

Then use something like ESC-CTRL-F for formatting the whole document
according to template. Here's the one I use:

Search for regexp: \R(//[^\n\r]*\R)+
Replace with regexp : \R

This way all lines begining with "//" are removed
