Run Danser CLI on new replay generated

watch-replays.ps1

###
# ABOUT: Watches for new replays and renders them with danser-cli
#
# HOW TO:
# 1. Download Danser from https://github.com/Wieku/danser-go and extract it
# 2. Download this script and place it in the same folder as danser-cli.exe
# 3. Open PowerShell and run the script with `.\watch-replays.ps1`
# 4. When new replays are created, they will be rendered with danser-cli
#
# NOTES:
# - This script will only watch for replays in the default osu! directory. If you have osu! installed in a different location, you will need to update the $OsuDir variable.
# - This script relies on a Danser settings preset which can be made easily in the Danser GUI. The preset name is set in the $DanserSettingsName variable.
###


# Update these variables to match your environment if necessary
$OsuDir = "$env:LOCALAPPDATA/osu!"
$ReplayDir = "$OsuDir/Replays"

# Internal variables
$WatcherName = "FileCreated"

# Unregister the event if it already exists

#  Watch for new replays

    IncludeSubdirectories = $false
    NotifyFilter = [System.IO.NotifyFilters]'FileName, LastWrite'
    EnableRaisingEvents = $true
}

# Process a new replay

    try {
        $DanserSettingsName = "4k"

        $ProcessOptions = @{

            ArgumentList = "-settings=`"$DanserSettingsName`" -out=`"$($eventArgs.Name)`" -replay=`"$($eventArgs.FullPath)`""
            Wait = $true
            WindowStyle = "Hidden"
        }

        # Execute danser-cli with the replay
        Start-Process @ProcessOptions
