Thanks.. pretty much what I thought up too. But it turns out to be a
little more complicated. There are other pieces in a few lines such
as a date string like `date' puts out by default, that has spaces.
And a few others
I'm thinking of splitting on something like ' +' (<spc><spc>+) since
no regular output will have 2 spc or more between connected
words.... I mean words that belong in a group.
A quick test with:
while(<>){
my @linar = split(/ +/,$_);
print "<" . @linar . ">\n";
}
Shows all lines split into 4 elements... which is what I want... then
I can test for a long element and fold it... maybe on commas since the
options are separated by commas.
Do you have any idea if that would cause significant cpu usage. I
mean testing every field for length. There would be 4 per line and
some 100+ lines. So, 400+ tests.
