A common case for string substitution is to just remove the found items. This patch changes the `String#[g]sub[!]` methods to allow that. Old usages: "foo".sub("o", "") #=> "fo" "foo".gsub("o", "") #=> "f" New usages: "foo".sub("o") #=> "fo" "foo".gsub("o") #=> "f" Applies to the bang versions as well. This commit changes the return values of String#gsub! call with a single argument and no block from an Enumerator to a String. The previous usage would return an Enumerator containing each match, which is not a string substitution. A suitable replacement should nonetheless be found before merging this commit. Before: "foo".gsub("o") #=> # Replacement: ??? ---Files-------------------------------- 0001-Add-a-default-empty-string-to-string-replacements.patch (2.2 KB) -- https://bugs.ruby-lang.org/
