You'll have to explain your js a little. At first glance, your
javascript code would seem to replace your entire first and last lines
with the null string.
Based on the output you present, though, your code will depend a great
deal on the complexity you want from your output. The main features
of your example, as I see them:
* You indent every line a few spaces.
* Yout indent lines that don't begin with 'function' or '}' a few more lines.
So something like this:
open OUT, ">" $your_out_file;
while (<>) {
if ( s/^\s*((?:function)|(?:\}))/ $1/i ) {
print OUT $_;
next;
} else {
s/^\s*/ /;
print OUT $_;
}
close(OUT);
If you have something that works, though, and you're using it other
places and want to keep everything synchronized, check out the
Javascript module from CPAN;
