Maybe @naruse can describe the reason it was deprecated over 11 years ago in commit:238b979f1789f95262a267d8df6239806f2859cc. In my opinion, as the one who changed the deprecation warning from verbose mode to always in 2.7 and removed the method in 3.0, it has various issues. The API is a bit too easy to misuse, as `URI.escape(' ', 'UTF-8')` returns `' '`. It doesn't escape URL query parameters as you would expect: `URI.escape(' ')` is `'%20'` and not `'+'`. It uses an RFC 2396 parser and not an RFC 3986 parser, so `URI.escape('[]')` is `'[]'` and not `'%5B%5D'`. Both `CGI.escape` and `URI.encode_www_form_component` are probably better general-purpose escaping methods. I generally prefer `CGI.escape` as it is written in C and should be significantly faster. Can you explain why `"http%3A%2F%2Fb%C3%BCcher.ch"` is invalid in your use case? For exactly the same behavior you can use `URI::DEFAULT_PARSER.escape(str)`. ---------------------------------------- Misc #17309: URI.escape being deprecated, yet there is no replacement https://bugs.ruby-lang.org/issues/17309#change-88377 * Author: chucke (Tiago Cardoso) * Status: Open * Priority: Normal ---------------------------------------- I'm on ruby 2.7.2 . The moment I do ```ruby uri = "http://b�cher.ch" URI.escape uri (irb):5: warning: URI.escape "http://b%C3%BCcher.ch" ``` I get that warning. Rubocop also tells me: """ URI.escape method is obsolete and should not be used. Instead, use CGI.escape, URI.encode_www_form or URI.encode_www_form_component depending on your specific use case. """ However, none of the suggestions does the same as `URI.escape`. ```ruby CGI.escape uri => "http%3A%2F%2Fb%C3%BCcher.ch" URI.encode_www_form_component uri => "http%3A%2F%2Fb%C3%BCcher.ch" URI.encode_www_form uri Traceback (most recent call last): NoMethodError (undefined method `map' for "http://b�cher.ch":String) Did you mean? tap ``` So my question is: why is this being deprecated? And if there's still reason, what to exactly replace it for, so I can keep the exact same behaviour? -- https://bugs.ruby-lang.org/ Unsubscribe:
