Vim with Powershell

I ran into a similar problem described by many here.

Specifically, calling

:set shell=powershell

manually from within vim would cause powershell to work fine, but as soon as I added:

set shell=powershell

to my vimrc file I would get the error "Unable to open temp file .... "

The problem is that by default when shell is modified, vim automatically sets shellxquote to " which means that shell commands will look like the following:

 powershell -c "cmd > tmpfile"

Where as this command needs to look like this, in order for vim to read the temp file:

 powershell -c "cmd" > tmpfile

Setting shellquote to " in my vimrc file and unsetting shellxquote (i.e. setting it to a blank space) seem to fix all my problems:

set shell=powershell
set shellcmdflag=-c
set shellquote=\"
set shellxquote=

I've also tried taking this further and scripting vim a bit using the system() call: system() with powershell in vim

It is a bit of a hack, but the following works in Vim 7.2. Notice, I am running Powershell within a CMD session.

if has("win32")
    set shell=cmd.exe
    set shellcmdflag=/c\ powershell.exe\ -NoLogo\ -NoProfile\ -NonInteractive\ -ExecutionPolicy\ RemoteSigned
    set shellpipe=|
    set shellredir=>
endif

function! Test()
  echo system("dir -name")
endfunction

Tested with the following...

• :!dir -name
• :call Test()
