Method to delete a substring by regex match
There is frequent need to delete a substring from a string. There already are methods
String#delete!, but their feature is a little bit different from the use cases that I am mentioning here.
I request methods that take a string or a regexp as an argument, and delete the matches from the receiver string. I am not sure of the method name, and I will use the term
remove here. It can be named in some other better way. I request all combinations of global vs. local, and non-destructive vs. destructive. The expected feature is something like the following. First, the non-destructive ones:
"abcabc".remove("c") # => "ababc" "abcabc".remove(/\zc/) # => "abcab" "abcabc".gremove("c") # => "abab" "abcabc".gremove(/c/) # => "abab"
Then, the destructive ones:
s = "abcabc" s.remove!("c") # => "ababc" s # => "ababc" s = "abcabc" s.gremove!("d") # => nil s # => "abcabc"
Using this, cases like https://bugs.ruby-lang.org/issues/12694 would be just special cases. They can be handled like this:
"abcdef".remove(/\Aabc/) # => "def"
