Date: Fri, 30 Oct 2020 15:06:39 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-17295.20201030150639.6346@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-17295.20201030150639.6346@ruby-lang.org
Issue #17295 has been reported by schneems (Richard Schneeman).
----------------------------------------
Feature #17295: Feature: Create a directory and file with Pathname#touch
https://bugs.ruby-lang.org/issues/17295
* Author: schneems (Richard Schneeman)
* Status: Open
* Priority: Normal
----------------------------------------
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.
Diff:
```
