# Perl, as a language, is far from my favorite.  However, this task is
# a good example of the kind of thing it is great at.  It would be hard
# to express this anywhere nearly as concisely in any other language.

# Note: This script isn't guaranteed to get things 100% correct, but it
# does do a pretty good job of guessing what is meant, and the remaining
# cases shouldn't be hard to fix by hand.
#
# As an example, it gets every instance of 'static' in the Lima mudlib
# correct (all 513 of them!).
#
# Example usage:
#
# find mudlib -name "*.c" -print | xargs /path/to/this/script

# Note that there is no checking whether things appear in quotes, which is
# probably the most likely way this can mess up.
#
# if it contains an open (, which is not part of a ({, ([, or (:, then it
# is a function prototype or definition
#
# Note: this is wrong for initializers that contain (.  For example
# static object this = this_object();  Perhaps we should handle =
# first ...
if (/\([^{[:]/) {
    s/static/protected/;
}
# commas and assignments are pretty clear indictations of variables.  Note
# that we don't have to worry about commas in argument lists since we have
# already handled lines with (, which must appear between static and any comma.
elsif (/,/ || /=/) {
    s/static/nosave/;
}
# static with a ; on the same line implies the entire line is here.  If it
# was a prototype, it had a (.  Must be a variable.
elsif (/;/) {
    s/static/nosave/;
}
# This handles the common practice of doing things like:
#
# static
# void create() {
#
# which is more common than most other uses of static alone on a line
else {
    s/static/protected/;
}
