Bug #11793
Updated by burnson (William Burnson) almost 10 years ago
Test case:
puts 'ab'.gsub('a', '\\\\+')
Expected output:
\\+b
Actual output:
b
The way I understand gsub(pattern, replacement) when used with two string arguments is that it will perform a literal replacement, so it is quite unexpected that substituting with \\+ \+ removes the pattern entirely.
