My inclination is to do the simple stuff programatically and do the
more complicated things by hand. A simple, dumb, ed script such
as the following is capable of changing the majority of things. It
doesn't attempt to deal with multi-line prototypes nor does it try
to convert prototypes that contain parens. These remaining things
can then be converted by hand.
Yes, you could hack up a perl script to try and do everything but
would you really trust it? I wouldn't. My script can be called
thusly:
find bin -type f | xargs convert.ed
#!/bin/sh
for f in $@; do
/bin/ed - $f <<'EOF'
%s/[ ]*__P[ ]*((\([^()]*\)))/(\1)/g
w
q
EOF
done
