require
An extension of Lua's require() function which adds support for Premake modules and version checking.
require ("modname", "versions")
Premake will use its extended set of module locations when locating the requested module.
Parameters
modname is the name of the module to be loaded. See Locating Scripts for more information about how Premake modules are located.
versions is an optional string of a version requirements. See the examples below for more information on the format of the requirements string. If the requirements are not met, an error will be raised.
Returns
The module object.
Availability
Premake 5.0 or later.
Examples
Require Premake version 5.0 or later.
require("premake", ">=5.0")
If no operator is specified, defaults to ">=". I think it is a little more readable to include it though.
require("premake", "5.0")
Require a version 5.0 alpha 3 or later.
require("premake", ">=5.0.0-alpha3")
Require anything between Premake version 5.1 and 6.0.
require("premake", ">=5.0 <6.0")
The same rules apply to third-party modules.
require("foo", ">=1.1")
