[erlang-questions] String Pattern Matching
Sun Sep 7 16:02:37 CEST 2008
I get the sense that most erlangers feel that regular expressions
aren't needed and that pattern matching can do the job.
I want to believe.
I really do.
But I am absolutely killing myself trying to port Ruby's
ActiveSupport Inflector over to erlang. It lets you pluralize and
singularize strings based on a set of rules.
([m|l])ouse$ -> $1ice
([^aeiouy]|qu)y$ -> $1ies
So, given that erlang has insufficient regular expression support to
tackle this (and given that I want to do this the "erlang way"), how
does one go about doing this?
The bit syntax won't work on arbitrary length fields as far as I
know. And I *really* don't want to invent my own subset/alternate
syntax of regular expressions that is more than what erlang supports
and less than a PCRE.
Thanks in advance,
