Powershell Linux: How to create simple argument TAB Completion for native Linux command

Question

Hi,

I just started learning Powershell on Linux (Debian).

What I try to do is the following.

I have a Bash script called "zst" in /usr/bin/
with TAB completions for it to complete arguments like:

zst <TAB> 

which gives me a list of possible arguments.
The TAB completer is a standard Bash script to create the strings ( just a curl call to some REST API).

If I use Powershell, of course I can run "zst" but without the TAB completions.

How can I achieve this?

I read something about ArgumentCompleters

https://adamtheautomator.com/powershell-parameters-argumentcompleter/

Can someone point me to the right direction?

Thanks in advance.

Answer 1

Not ever having done this, I expect you'd start by using "Set-PSReadlineKeyHandler" and including in its scriptblock the completions you want to offer for a given keystroke or chord. Include the Set-PSReadlineKeyHandler cmdlet(s) in your PowerShell profile (sorry, I don't know where that is located in *nix) -- if it was Windows it'd be here: C:\Users[User]\Documents\WindowsPowerShell\profile.ps1.

Answer 2

Thanks for the hint. I will try it with Set-PSReadlineKeyHandler.

In the meantime I succeeded with the following solution

Register-ArgumentCompleter -Native -CommandName zst -ScriptBlock {
     param($wordToComplete)
     (curl -s https://server/resources/txt | grep ^$wordToComplete)
}
