Wrapper function with same name as command in Powershell?

Question

I am making attempting to fix an app which has recently broken the ls command, using a Powershell wrapper script. My wrapper must have the same name as the command it is invoking, so I'm using invoke-command to call the original command.

# yarn broke 'ls'
function yarn() {
    $modifiedArgs = @()
    foreach ( $arg in $args ) {
        if ( $arg -cmatch '^ls$' ) {
            $arg = 'list'
        }
        $modifiedArgs = $modifiedArgs + $arg
    }
    invoke-command yarn -ArgumentList @modifiedArgs
}

However invoke-command fails with

Invoke-Command : Parameter set cannot be resolved using the specified named parameters

How can I run the original command with the modified parameters?

Edit: I've also tried -ArgumentList (,$modifiedArgs) per Passing array to another script with Invoke-Command and I still get the same error.

Edit: Looks like invoke-command is remoting only. I've also tried Invoke-Expression "& yarn $modifiedArgs" but that runs the function itself.

Answer 1

Per the powershell docs the & operator works:

# yarn broke 'ls'
function yarn() {
    $modifiedArgs = @()
    foreach ( $arg in $args ) {
        if ( $arg -cmatch '^ls$' ) {
            $arg = 'list'
        }
        $modifiedArgs += $arg
    }
    & 'C:\Program Files (x86)\Yarn\bin\yarn.cmd' $modifiedArgs
}

Still happy to accept other answers that don't involve specifying the command path explicitly.

I belive you can get around needing to specify the full path to the command if you scope the wrapper function to Private:

# yarn broke 'ls'
function Private:yarn() {
    $modifiedArgs = @()
    foreach ( $arg in $args ) {
        if ( $arg -cmatch '^ls$' ) {
            $arg = 'list'
        }
        $modifiedArgs += $arg
    }
    & yarn $modifiedArgs
}

This will prevent the function from being visible to child scopes, and it will revert back to using the application.
