Configuration

evoker config changes how evoker itself behaves. It never touches a pack, a server's own settings (server.properties, configs) or a Prism instance's game settings.

evoker config                      # every setting and its value
evoker config jvmArgs              # one setting
evoker config jvmArgs '["-Xmx6G"]' # change it
evoker config updateOnStart false

List and true/false settings take JSON (["-Xmx6G"], false); the others take the text as typed (D:\Games\Prism\instances). Unknown settings and values of the wrong kind are errors.

Which settings

It depends on where you run it:

• In a server folder (one with a .evoker folder): that server's settings, stored in .evoker/config.json.
• Anywhere else: your user settings, stored in %APPDATA%\evoker\config.json (Windows), ~/Library/Application Support/evoker/config.json (macOS) or ~/.config/evoker/config.json (Linux, or $XDG_CONFIG_HOME/evoker).

--user uses your user settings even inside a server folder.
