concatenation of character classes with oniguruma and joni regexes
August 21, 2009
i was pleasantly surprised by some regex goodness present in oniguruma [ ruby 1.9 ] and joni [ jruby ]
regexes can concatenate character classes, so you can do things like match against “all unicode whitespace except newlines” thus :
/[[^\n]&&[:space:]]+/
