I can't seem to get Oniguruma to look for a single backslash, am I
doing anything wrong here?:
I should be able to escape the single with another:
irb(main):043:0> reg = Oniguruma::ORegexp.new('\\')
ArgumentError: Oniguruma Error: end pattern at escape
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:177:in
`old_initialize'
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:177:in `initialize'
from (irb):43:in `new'
from (irb):43
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:359
For arguments sake, with just one backslash:
irb(main):044:0> reg = Oniguruma::ORegexp.new('\')
irb(main):045:1'
(with just one back-slash, irb sees unfinished syntax)
Same if I use double-quotes:
irb(main):046:0> reg = Oniguruma::ORegexp.new("\\")
ArgumentError: Oniguruma Error: end pattern at escape
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:177:in
`old_initialize'
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:177:in `initialize'
from (irb):46:in `new'
from (irb):46
from /usr/local/lib/ruby/site_ruby/1.8/oniguruma.rb:359
Double quotes with just one backslash:
irb(main):047:0> reg = Oniguruma::ORegexp.new("\")
irb(main):048:1"
