I'm having trouble with backslashes and I don't know what is wrong. I
can't seem to write and expression that will evaluate to a string
containing a single backslash character as in "\". It seems that "\"
in Ruby evaluates to "\" not to "\" as I would expect. Below are a few
things I've tried. If anyone could send back a quick answer it would be
res = "c:/foo/bar".gsub(/\//, "\") # -> c:\foo\bar
res = "c:/foo/bar".gsub(/\//, '\') # -> c:\foo\bar
#res = "c:/foo/bar".gsub(/\//, "\") # -> syntax error - unterminated
string meets end of file
#res = ...
