Do you know where your variables are? PerlMonks

### Comment on

 Need Help??
A friend of mine recently had an assignment where he had to split up a text file and print it out as a triangle. Of course this was in "c" and so, just because I could I had to see just how simple it would be in perl. The idea is to take a ctriangle.txt file like
```a a a a a a a a a
a a a a a a a a a
a a a a a a a a a
a a a a a a a a
and end up centered over 80 chars
```       a
a a
a a a
a a a a
a a a a a
a a a a a a
a a a a a a a
a a a a a a a
```          The
same
principle
applies to
any text file,
basically splitting
words only on spaces
or new lines
My best shot was 132 chars (\n inc). I especially like the new trick I learnt.
```/[
]+/
Which matches space/new line combinations.

Well this is the best I could do, after staring at it for half an hour it wasnt getting any shorter.

```open F,"ctriangle.txt";sub n{print
" "x(40-\$r/2)."\$x\n"};for(split/[
]+/,join'',<F>){\$c=\$r,n,\$x=''if(
\$r=length(\$x.=" \$_"))>\$c}n

Update:
With jeroenes idea, if I undef \$/ by assigning it undef from an unused variable (not pretty but we're talking size) its down to 128 chars.

```open F,"ctriangle.txt";sub n{print
" "x(40-\$r/2)."\$x\n"};\$/=\$w;\$_=<F>;
for(split){\$c=\$r,n,\$x=''if(
\$r=length(\$x.=" \$_"))>\$c}n

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Posts may use any of the Perl Monks Approved HTML tags:
a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
• Link using PerlMonks shortcuts! What shortcuts can I use for linking?
