Simple Template Engine for PowerShell

Here is a simple, token-replacement template engine for PowerShell that you might find useful.

function Merge-Tokens($template, $tokens)
{
    return [regex]::Replace(
        $template,
        '\$(?<tokenName>\w+)\$',
        {
            param($match)
            
            $tokenName = $match.Groups['tokenName'].Value
            
            return $tokens[$tokenName]
        })    
}

You use it like this.

Merge-Tokens 'Hello, $target$! My name is $self$.' @{
        Target = 'World';
        Self = 'Brice'
    }

The output of that command, as you would expect, is this.

Hello, World! My name is Brice.

Enjoy.
