Subject: Incorrect evaluation of ~ test in ternary conditional
Date: Fri, 15 Dec 2017 13:55:03 +0000	[thread overview]
Message-ID: <DB6P194MB0037AE570D0106FB365F3C549D0B0@DB6P194MB0037.EURP194.PROD.OUTLOOK.COM> (raw)

Hi everybody!

Let there be a directory ~/work. Using the ~ test character in a 
conditional ternary prompt will return incorrect results when the 
argument is 2 as shown below:

$ cd && print -P "%(2~:true:false)"
false
$ cd work/.. && print -P "%(2~:true:false)"
true

The docs say: 
(http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html#Conditional-Substrings-in-Prompts)

 > c [...] . [...] ~ [...] True if the current path, with prefix 
replacement, has at least n elements relative to the root directory, 
hence / is counted as 0 elements.

So the first command behaves properly, but the second one doesn't.

I'm using zsh 5.0.5. Can somebody confirm this for the current version 
of zsh as well?

BR, Felix
