Subject: Silly question on :h and = expansion
Date: Tue, 17 Aug 2021 12:39:07 -0500	[thread overview]
Message-ID: <CAMP9c5m8cBSfzSBgDEvadZFOKNMd7sE-qXFrjCxFKXYj6SDxrQ@mail.gmail.com> (raw)

Quick question, the answer is probably "just use dirname".

I really like the flexibilty of Zsh expansion, particularly "=foo" to
effectively expand to the full path, and as best I know it's
functionally equivalent to "${commands[foo]}".

I also like the ":h" modifier that's equivalent to "dirname" (and all
of its siblings, but that's the only relevant one for this post).

I would like to simplify the process of "print the directory
containing" or "cd to directory containing" some file in $PATH.

I know I can do either of

* $(basename =foo)
* ${commands[foo]:h}

But I was hoping there was a way to combine the "=" and ":h" expansion
into one line.  As best I can tell, there isn't -- but I figured it
was worth asking.
