Wonderful. Is there a "routine golf shortenings" node?


I humbly seek wisdom.

    There's a number of tips and techniques listed in Perl Golf 101 as well as in the comments to that node.

    --chargrill
    s**lil*; $*=join'',sort split q**; s;.*;grr; &&s+(.(.)).+$2$1+; $; = qq-$_-;s,.*,ahc,;$,.=chop for split q,,,reverse;print for($,,$;,$*,$/)

      Wow, that's a nice node that I wasn't previously aware of. The basic shortenings I made were:

      • all variable names one char in length
      • eliminate variables where you can
      • removed quotes from strings (e.g. "FRED" -> FRED)
      • $x=1;$y=1 -> $x=$y=1
      • shift -> pop in subs
      • removed return in subs
      • split // -> /./g
      • for {...} -> ... for
      • if {...} -> ... or ...
      • ' ' -> $"
      These all seem to be mentioned in Perl Golf 101, except perhaps the last one. BTW, I've added Perl Golf 101 to the list of references in The Lighter Side of Perl Culture (Part IV): Golf.
