Hi.

I'm glad that methyl brought this up.

I've been leisurely following ruby for a few years. I have one production code, glark, written in ruby. It is a grep-like utility, with lots of bells and whistles -- very slow, but very convenient in some situations. You might find it in one of your repositories, or at:
incava.org

However, whenever I have tried to execute kurumi's one-liners, say:
Code:
ruby -ne 'BEGIN{s = 0};s+=$_.to_f;END{print "Total: #{s}\n"}' file

I get:
Code:
-e:1: undefined method `+' for nil:NilClass (NoMethodError)

This is from:
Code:
ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]

but I also got it on new install of ruby-full on:
Code:
OS, ker|rel, machine: Linux, 2.6.32-24-generic, i686
Distribution        : Ubuntu 10.04.1 LTS (lucid) 
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]

Something simple, perhaps, that I am over-looking? ... cheers, drl

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
