Here it is (in Perl):
<code>
use strict;
use warnings;
open FILE, '/path/to/file/'
or die 'Couldn't open file: $1';
open OUTPUT '>/path/to/output_file/';
while (<FILE>) {
my $line = $_;
# my $line = 'This isA lineWithSome words both in camelCaseAnd not.';
$line =~ s/(\S+?)([A-Z])(\S+?|\s+?)/$1_$2$3/g;
print OUTPUT "$line\n";
}
</code>
That commented out part is where I had inserted the line for testing. I haven't
tried it with a file, but the regex is, at least, accurate.
Hope this helps,
Tony
