# Instructions:
# 
# 1. Open PowerShell from your start menu as administrator, paste this command then hit Enter (to be able to run the script): Set-ExecutionPolicy Bypass -Scope Process -Force
# 
# 2. Download this file to your **OMSI 2 maps folder** - it must be run from there - e.g.:
# C:\Program Files (x86)\Steam\steamapps\common\OMSI 2\maps
# D:\Games\OMSI 2\maps
# 
# 3. Run the script.
# 
# 4. Wait till it says "Finished."
# 
# 5. Access the text file created in your maps folder called `My largest OMSI maps (in tiles) DD-MM-YYY_HHMMSS.txt`


# Determine name of file to output to
$baseName = 'My largest OMSI maps (in tiles) '
$dateTime = Get-Date -Format 'dd-MM-yyyy_HHmmss'
$extension = '.txt'
$fileName = ($baseName + $dateTime + $extension)
$outputPath = Join-Path -Path $PSScriptRoot -ChildPath $fileName


# Create file
New-Item -Path $outputPath


# Strings
$header1 = '----------------------------------------------'
$header2 = 'Number of tiles | Map name'
$header3 = '----------------------------------------------'


# Iterate over all OMSI maps
foreach ($folder in Get-ChildItem -Directory)
{
	
	# Get count of *.map
	(Get-ChildItem -LiteralPath $folder -Filter '*.map' -File -Recurse -Depth 0).Count | Out-File -Append -NoNewline -FilePath $outputPath

	# Alternative stricter options (incase of cmd regex like *.map* automatically):
	# (Get-ChildItem -LiteralPath $folder -Filter '*.map' -File -Recurse | Where-Object { $_.Extension -match '\.(map)$' }).Count | Out-File -Append -NoNewline -FilePath $outputPath
	# (Get-ChildItem -LiteralPath $folder -File -Recurse | Where-Object { $_.FullName -like "*.map" }).Count | Out-File -Append -NoNewline -FilePath $outputPath
	
	# Insert tab
	'			' | Out-File -Append -NoNewline -FilePath $outputPath
	
	# Insert map name and new line
	$folder.Name | Out-File -Append -FilePath $outputPath

}


# The results
$output = Get-Content $outputPath


# The results sorted by highest count of *.map files
$sorted = $output -split '\r?\n' | Sort-Object -Descending { [int] (-split $_)[0] }


# Prepend table header and overwrite same file with final contents
$header1 | Out-File -FilePath $outputPath
$header2 | Out-File -Append -FilePath $outputPath
$header3 | Out-File -Append -FilePath $outputPath
$sorted | Out-File -Append -FilePath $outputPath


# Indicate status to user
Write-Output "`n"
Write-Output "Finished!"
Write-Output "`n"


# Wait for user confirmation to close window
