PSParser Tokenize with Switch Default fails #13462
Description
Trouble when trying to Tokenize a script containing a Switch-statement with a Default case in Powershell 7.1.0-preview.5. This works as expected in Powershell 7.0.3 (stable). If one does comment-out the default case, it works as expected. This has been reproduced on more than one computer.
Steps to reproduce
Create a file containing a simple function that has a switch-statement with a default case (see below). Save that file. Then try to tokenize that file (also see below) from a console running Powershell 7.1.0-preview.5.
# Save this as a file called 'TEST.ps1'
Function Test {
Param (
$String
)
Switch ($String) {
"test" {
"sfdsf"
}
"test2" {
"sfdsf"
}
default {
"sdfsdf"
}
}
}# From a Powershell 7.1.0-preview.5 prompt execute the following:
$scripts = Get-ChildItem -Path "C:\__TEMP\TEST.ps1"
Foreach ($file in $scripts) {
$contents = Get-Content -Path $file.fullname -ErrorAction Stop
$errors = $null
$null = [System.Management.Automation.PSParser]::Tokenize($contents, [ref]$errors)
$errors.Count -eq 0
}Expected behavior
True
Actual behavior
