Conversion of input parameter values

[cdhunt]

The binary I'm working with takes a comma-delimited list of strings. I would like to take in a string[] and simply -join '' at runtime.

Args list should look like this

list
items
--categories
passwords,logins

Currently looks like this.

list
items
--categories
passwords
logins

Definition

        {
            "Name": "Categories",
            "OriginalName": "--categories",
            "ParameterType": "string[]",
            "Description": "Only list items in these categories",
            "Position": 0
        },

+1 on this, parameter transformation is also very commonly needed for all types of array parameters. Sometimes you need to pass each value as with the same repeated parameter, sometimes it's encoded as a single value joined by a character like ',', etc.

One example is the Docker CLI that takes environment variables as a series of "-e NAME="VAL"" parameters. Here's how I do it:

+1 too. I would like to transform a PSCredential so I can map it to --username and --password. Cause we all know that is not secure. Related to #34

Glob Pattern strings need to be single quoted before passing to native cmd

I am working on GitHub CLI and need to have an input parameter single quoted since it is a glob pattern. Without the single quotes, at runtime it executes the glob matching before the native command gets control. As an experiment, I tried specifying the string like "'*pkg'" to the PowerShell parameter - but the native cmd could not find a match. I was able to test the native cmd successfully using --pattern '*pkg'

# download only Debian packages for the latest release
$ gh release download --pattern '*.deb'

Copy-GHReleaseAsset -Tag 'v7.1.1' -Pattern "'*pkg'"  -Repo 'PowerShell/PowerShell' -Verbose
VERBOSE: gh
VERBOSE: release
VERBOSE: download
VERBOSE: v7.1.1
VERBOSE: --pattern
VERBOSE: '*pkg'
VERBOSE: --repo
VERBOSE: PowerShell/PowerShell
VERBOSE: Performing the operation "Copy-GHReleaseAsset" on target "gh".
no assets match the file pattern

@cdhunt -- We agree that this would be a good addition. For a workaround today, see #31 (comment)
