在vim中查找可执行文件的路径

Question

On some machines I'm using an external executable to format text (it's named 'par'). Therefore I'd like to detect if the executable is installed.

Edit: I just want to detect if the executable is available in my .vimrc itself. So I prefer internal functions over external utils like 'which'. Prince Goulash's solution is already very helpful and I'm going with it, despite I'd prefer finding the exact path. Thanks.

Answer 1

You can use the vimscript function executable() , which returns 1 if its argument exists and is executable, and 0 otherwise. It doesn't return the path of the file, though. See help executable for more info.

Answer 2

In linux, I'd use which :

:!which par

If you want to put it into the file, try this:

:r !which par

Edit: Actually, hash might be the better tool to use.

Answer 3

in unix...

whereis par

should return a path, if it is executable by the current user
