[Doxygen-users] plugin / filter not behaving as expected

[Clayton <cla...@gm...>]

Hi all,

I am prototyping a plugin a la

	http://www.stack.nl/~dimitri/doxygen/helpers.html

for html / js / css (GitHub repos tagged as "html") to use Doxygen to
analyze certain aspects of this kind of code. As a for-instance,
attached is an actual syntax.css file pulled from a repo, and the
corresponding syntax.cpp output after I pass it through my filter. g++
reports no syntax issues with syntax.cpp, and Doxygen, with a default
Doxyfile, processes syntax.cpp and produces a list of classes as
expected.

BUT.... If I configure Doxyfile with my css filter:

	INPUT_FILTER = /path/to/plugins/webplugin/web2doxy.pl
	FILE_PATTERNS = *.css

absolutely nothing happens. No output, no errors, nothing. (Note that I
have already seen this working sometimes with some other filters built
by other people.)

Any ideas about what might be missing in my simple configuration above?
Assuming Doxygen is presenting syntax.css to stdin of my filter
unmodified, the filter should be giving Doxygen back exactly the
content of syntax.cpp on it's stdout.

But why the different behavior?

Thanks for any insights,
Clayton
