This was attempt to see if using format() would be shorter. It wasn't. It does use some of Perl's dustier artifacts however:
#!/usr/bin/perl -wall -00n
use strict;
END{
@_=shift@F;
while(@F){
$_=shift @F;
$_.=' '.shift@F while(length$_<=length$_[-1]&&@F);
push@_,$_
}
formline(('@'.('|'x80)."\n")x@_,@_);
print $^A
}
Update: Using MeowChow's regex this can be reduced to 89 chars + 6 command line switches. I'm not proud of this:
#!/usr/bin/perl -w -00nal
use strict;
END{
$_="@F ";
@F=1;
formline'@'.('|'x80)."\n",$&and@F=length$&while/.{1,@F}.*? /g;
print$^A
}
John.

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
