powershell equivalent to get-argumentcompleter

Question

Register-ArgumentCompleter is an incredibly useful function but I have a suspicion that overzealous use of it by some modules has caused my shell to slow down. I would like to see a list of all the ArgumentCompleters that are Registered in my Session.

I had an idea for how to write one, but it is overly complex and I have my doubts it would work, so if anyone knows of a solution already I would greatly appreciate it.

Answer 1

Have a look at the module ImpliedReflection

You can then use this line to read the argument completers. To access with without the ImpliedReflection module, use standard .net reflection.
