GM command syntax - VanaDev/Vana GitHub Wiki
This is the "language" that the in-game help system and the command reference use to convey valid command syntax.
Required arguments are enclosed in less than and greater than symbols.
<$command>
Optional arguments are enclosed in brackets.
[$command]
String arguments are expressed through using the $ character.
[$command]
Number arguments are expressed through using the # character.
[#time in seconds]
Choices are expressed as a set within braces.
<${all | items | drops | mobs | beauty | shops | scripts | reactors | pets | quests | skills}>
This example means that all of the choices are strings and provides all the valid choices. It also conveys that a choice must be present.
<{$map string | #map ID}>
This example means that you must choose between a valid map string or a map identifier.
