Auto-completions do not work

[heaths]

Using nbgv v3.3.37+0989e8fe0c

It seems middleware for System.CommandLine like [parse] and [debug] do not work, thus breaking autocompleters in bash, PowerShel, etc.

For example,

dotnet-suggest get -e C:\Users\username\.dotnet\tools\nbgv.exe --position 5 -- nbgv

error: unknown command '[suggest:0]'
nbgv v3.3.37+0989e8fe0c
Use -h, --help, or -? for usage help. Use after a command to get more help about a particular command.

Another example:

nbgv [parse] --foo

nbgv v3.3.37+0989e8fe0c
Use -h, --help, or -? for usage help. Use after a command to get more help about a particular command.
error: unknown command '[parse]'

This should have printed the tokens, and is what dotnet-suggest seems to use to provide completions automatically. For example:

dotnet-suggest [parse] get -e foo -p bar

[ dotnet-suggest [ get [ -e <foo> ] [ -p !<bar> ] ] ]

I saw that feature advertised recently too. I tried it on a new tool I wrote and it didn't work there either.
I don't expect it to work on nbgv because it uses a very old version of the System.CommandLine library. But the new tool I wrote used the latest one and still failed. So IMO this is a non-goal until I see it working somewhere.

It works great for me across a myriad of tools, including dotnet-suggest, dotnet-trace, dotnet-format, coverlet.console, and more. nbgv is the only one I have installed that doesn't.

Please open the bug back up and I can upgrade to a newer System.CommandLine if you want. I use it across my projects frequently.

...and if you explain how you tried it and it didn't work for you, I can probably suggest what you could try instead. For example, if modifying your PowerShell $profile per instructions, you either need to start a new PowerShell source or re-dotsource your $profile.

See below. Note, also, that for dotnet-* tools you have to use dotnet-<name> instead of dotnet name because the autocompleter is registered to the application name, which is dotnet-<name>.
