Nuby - help on string spliting

Dany Cayouette

9/30/2004 9:25:00 PM

Any advice/ideas on the best way of attacking field split on ';' when the string looks like:

s = 'a;b;c\;;d;'

i.e. field delimiter is ';', and if ; appears in field data ; => \;

Any regex magic? or should I use s.each_byte and do it by hand?

Thanks,
Dany

hmmm.. your mail looks exactly like a mail I have replied to 2 minutes ago.
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-t...


something like this

irb(main):023:0> "aa;bbb\\;;abc;;d\\\\;e;f".scan(/(?:\A|;)((?:\\[^.]|[^;])*)/)
{ p $1 }
"aa"
"bbb\\;"
"abc"
""
"d\\\\"
"e"
"f"
=> "aa;bbb\\;;abc;;d\\\\;e;f"
irb(main):024:0>


btw: are you solving some kind of exercise ?

No. Mark introduced me to ruby. He's a programmer;I'm not! so I usually bounce questions off him. Got confused as I thought he was telling me to post to comp.lang.ruby, while he was actually posting himself. Sorry for the duplication...
