Ternary operator in PowerShell

Question

From what I know, PowerShell doesn\'t seem to have a built-in expression for the so-called ternary operator.

For example, in the C language, which supports the terna

Answer 1

I've recently improved (open PullRequest) the ternary conditional and null-coalescing operators in the PoweShell lib 'Pscx'
Pls have a look for my solution.

My github topic branch: UtilityModule_Invoke-Operators

Functions:

Invoke-Ternary
Invoke-TernaryAsPipe
Invoke-NullCoalescing
NullCoalescingAsPipe

Aliases

Set-Alias :?:   Pscx\Invoke-Ternary                     -Description "PSCX alias"
Set-Alias ?:    Pscx\Invoke-TernaryAsPipe               -Description "PSCX alias"
Set-Alias :??   Pscx\Invoke-NullCoalescing              -Description "PSCX alias"
Set-Alias ??    Pscx\Invoke-NullCoalescingAsPipe        -Description "PSCX alias"

Usage

 |?:

As expression you can pass:
$null, a literal, a variable, an 'external' expression ($b -eq 4) or a scriptblock {$b -eq 4}

If a variable in the variable expression is $null or not existing, the alternate expression is evaluated as output.
