Issue #17295 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Assigned to Rejected `Pathname#touch` is rejected at [this reason](https://bugs.ruby-lang.org/issues/7361#note-5). I asked this proposal to @akr again, he is still negative for `Pathname#touch`. ---------------------------------------- Feature #17295: Feature: Create a directory and file with Pathname#touch https://bugs.ruby-lang.org/issues/17295#change-110058 * Author: schneems (Richard Schneeman) * Status: Rejected * Assignee: akr (Akira Tanaka) ---------------------------------------- Right now if a developer wants to create a file and is not sure if the path exists yet or not they must: ```ruby Pathname.new("/a/b/c/d.txt").tap {|p| p.dirname.mkpath; FileUtils.touch(p)} ``` After this patch a developer can instead call: ```ruby Pathname.new("/a/b/c/d.txt").touch ``` An alternative name for this behavior could be `mkfile` but I think it is confusing to have a `mkfile` and a `mkpath` where one creates a directory and one creates a file.
