Issue Description
I am experiencing a problem with syntax highlighting inside a ValidatePattern attribute on a parameter.
The highlighting seems to break if I make use of a closing round bracket ) inside the validation pattern.
In that part of the pattern, I want the URL to optionally have videos/ in it.
Here is the code from the screenshots, to save from having to type it out when reproducing:
$ErrorActionPreference = "Stop"
Set-StrictMode -Version Latest
function Convert-UrlForApi {
param(
[Parameter(Mandatory=$true)]
[ValidatePattern('^http:\/\/www.giantbomb.com\/(videos\/)?[a-z0-9\-]+\/[0-9]+-')]
[ValidateScript({[Uri]::IsWellFormedUriString($($_), [UriKind]::Absolute)})]
[String]$Url
)
if ($Url -match "\/3030\-[0-9]+\/$") {
return "http://www.giantbomb.com/api/game$($Matches[0])"
} elseif ($Url -match "\/2300\-[0-9]+\/$") {
return "http://www.giantbomb.com/api/video$($Matches[0])"
} else {
return $null
}
}
Please see the screenshots below.
The function itself executes fine and works absolutely as expected and desired with the round bracket in place, so it's just the syntax highlighter getting confused about the round bracket inside the pattern string.
