Vanaportal Updater

Updater companion for VanaPortal, written in Go.

Overview

• Started by Vanaportal (plugin) automatically on load.
• If started manually, it expects the Windower root path.
• Derives:
  • root/plugins/ for the plugin files.
  • root/addons/Vanaportal/ for the addon files.
  • root/addons/Vanaportal/data/update.json for metadata
  • root/addons/Vanaportal/data/tmp/ for staged zip assets
  • root/addons/Vanaportal/data/updater.state.json for handled/staged state
• Watches the game process pol.exe.
• While pol.exe is running, it look for new releases and stages new zip files.
• When pol.exe process is no longer detected, it applies any staged updates and exits.
• plugin and addon are updated independently.

Metadata

The updater writes a JSON metadata file:

{
  "channel": "stable",
  "status": "idle",
  "plugin": {
    "version": "",
    "download_url": "",
    "staged": false
  },
  "addon": {
    "version": "",
    "download_url": "",
    "staged": false
  }
}

status values:

• idle
• update_available
• staged
• applying
• applied
• error

Notes

• Zip archives are extracted directly into the target directories.
• Already handled versions are persisted in updater.state.json so the updater does not re-download the same release on every run.
