EvergreenUI

1.0.7-beta

Private/Get-UIConfig.ps1

#Requires -Version 5.1
<#
.SYNOPSIS
    Reads the EvergreenUI user configuration from disk.
 
.DESCRIPTION
    Loads $env:APPDATA\EvergreenUI\settings.json and returns a PSCustomObject.
    If the file does not exist or is malformed, returns a default config object.
    Never throws - a missing or corrupt config is treated as first-run.
 
.OUTPUTS
    PSCustomObject with properties:
        OutputPath : string - last-used download output path
        LibraryPath : string - last-used library path
        Theme : string - 'Light' or 'Dark'
        LogVerbosity : string - 'Normal' or 'Verbose'
        LogVisible : bool - whether the progress log panel is expanded
        LogHeight : int - log panel height in pixels
        ShowImportTab: bool - whether the Import tab is visible in navigation
        StartupView : string - 'Apps' | 'Download' | 'Library' | 'Import' | 'Settings' | 'Update' | 'About'
        LastAppName : string - last selected app in Apps view
        WindowWidth : int - last window width
        WindowHeight : int - last window height
