(Ovid) RE: Pig Latin

Here's the shortest that I could come up with:

s/\b((qu|[bcdfghjklmnpqrstvwxyz]+)?([a-z]+))/$2?$3.$2."ay":$1."way"/eg
+;
[download]

Points to note:

It handles multiple consonants at the start of the word (i.e. "this" comes "isthay")
It handles 'qu'.
It's terribly inefficient, but then, I guess that wasn't the point :)

Here's the full breakdown, if anyone's interested:

#!/usr/bin/perl -w

my $test = "that is the time for all good men to come to the aid of th
+eir country.";
$test=~s/
         \b                            # start of word
         (                             # capture all to $1
           (                           # this is $2
             qu                        # word starts with qu
             |                         # or
             [bcdfghjklmnpqrstvwxyz]+  # a consonent
           )?                          # but it's optional
           (                           # this is $3
              [a-z]+                   # rest of word
           )
         )
        /$2 ? $3.$2."ay" : $1."way" /xeg;   # if $2 evaluates as true 
+then 
                                            # put it at end of word an
+d add "ay"
                                            # otherwise, just add "way
+"
print $test;

I'm just playing through. I made your code case-insensitive and did a bit of regex tomfoolery. `# updated (5 years later!) s/\b(qu\|[^\W0-9aeiou_]+)?([a-z]+)/$1?"$2$1ay":"$2way"/ieg;` [download] I don't see the need to save 3 pieces of data. And using `[^\W0-9_]` is shorter than `[bcdf..xyz]` and `[b-df-hj-np-tv-z]` and it forces the reader to think for a second. `;)`. And I saved space with the quoting on the RHS. Score: 53. `$_="goto+F.print+chop;\n=yhpaj";F1:eval`	[reply] [d/l] [select]

japhy, originally, I was constructing a rather longer and optimized script to do the pig latin conversion. Then I went back and reread vroom's specs. First, I didn't use the /i modifier because he said we were to assume the data was lowercase and he wanted the shortest possible code. The reason I am using three backreferences is because the data saved to $2 is tricky. Your equivalent (ignoring the "qu" problem) is `[^\W0-9_]`. This allows you to match all alphabeticals but does no discrimination for vowels. However, you apeared to notice this when you mentioned `[b-df-hj-np-tv-z]`. Therefore, I suspect that you intended the following and (assuming you did intend this) I offer you kudos for a clever regex: `s/\b(qu\|[^\W0-9_aeiou]+)?([a-z]+)/$1?"$2$1ay":"$2way"/ieg;` [download] I also noticed that, in this case, using the /i modifier ignored vroom's "lowercase" spec, but does result in a shorter regex.

Oh, d'oh, I'm silly. I meant to add 'aeiou' to the character class, I really did, since that was the whole reason I introduced it. :) And I'm sorry I hadn't checked vroom's specs. By the way, since Pig Latin does not produce a 1-to-1 mapping of normal strings to PL-strings, you can't reasonably reverse this process. Example: flea and leaf both go to eaflay. `$_="goto+F.print+chop;\n=yhpaj";F1:eval`	[reply]

`[bcdfghjklmnpqrstvwxyz]+` can become `[bcdfghj-np-tv-z]+` to save six bytes without loss of accuracy.	[reply] [d/l] [select]
