Package: ruby-rchardet
Version: 1.3-1
Severity: important
Tags: patch
Hi there,
Trying to use ruby-rchardet using ruby1.9.1 gives syntax errors when
loading the module. See the following output:
bram@debian:~$ irb1.9.1 -rrchardet
<internal:lib/rubygems/custom_require>:29:in `require':
/usr/lib/ruby/vendor_ruby/rchardet/chardistribution.rb:60: syntax error,
unexpected ':', expecting keyword_then or ';' or '\n' (SyntaxError)

This is because a number of "if" and "for" statements end with a colon,
which was apparently valid in ruby1.8, but is not valid in ruby1.9.1.
Attached is a patch that removes these colons, so that ruby-rchardet
loads without syntax errors.
Cheers,
Bram Senders
