Validate an arbitrary number of PowerShell script parameters
It is possible in PowerShell to validate the parameters passed to a script and also enables auto completion, as seen below:
myscript.ps1:
param([Parameter(Mandatory=$false)][String][ValidateSet('abc',
'def',
'ghi')] $argument
)
But this only enables the auto completion for the first argument. I want number of "auto complete"-able parameters to be arbitrary.
Therefore after typing:
PS C:> .myscript.ps1 def(additional white space at the end) and- pressing tab, I want the possible parameters to be auto completed again
PS C:> .myscript.ps1 def abs
How do I code this in the param(...) part?

If you do want to pass values as individual arguments separated with whitespace, use the ValueFromRemainingArguments parameter attribute:
param(
[Parameter(ValueFromRemainingArguments)]
[ValidateSet('abc', 'def', 'ghi')]
[string] $argument
)
Note that $argument is now an array of values, in which PowerShell collects all positional arguments for you.
The potential down-side is that this subjects all positional arguments to the validation, so if you also need to pass other arguments, you'll have to prefix them with the parameter name (e.g., -foo bar).
Therefore, consider using a single, explicitly array-valued parameter instead:
param(
[ValidateSet('abc', 'def', 'ghi')]
[string] $argument
)
That way, $argument will receive multiple values if passed with , as the separator, and in addition to tab-completing the 1st value, each additional one after typing , can be tab-completed too.
./myscript a<tab> # -> ./myscript abc
./myscript abc, d<tab< # -> ./myscript abc, def
