Require

Loads Lua and JSON files at runtime, from your own resource or from another one.

New in v4.1.0

MSK.Require has no exports. The cache belongs to the resource that uses it.

Paths​

  • Without @ the file belongs to your own resource: 'shared.utils'
  • With @ it belongs to another resource: '@my_lib/client/helpers.lua' or '@my_lib.client.helpers'
  • For Load and Json the extension is optional. As long as the path contains no slash, dots separate folders, so shared.utils becomes shared/utils.lua.

On the client, a file can only be read when the resource that owns it lists it in its fxmanifest.lua under files { ... }.

MSK.Require.Load​

Runs a Lua file once and returns its return value, just like require. The result is cached, the next call with the same path returns the cached value without running the file again. A file that returns nothing is cached as true. The module is callable, so MSK.Require(path) does the same.

A file that requires itself, directly or through other files, raises an error instead of looping forever. Compile and runtime errors are raised with the file name.

Parameters
path - string - Path of the Lua file

Returns
value - any - The return value of the file

local value = MSK.Require.Load(path)

-- Example
local Utils = MSK.Require.Load('shared.utils')            -- shared/utils.lua
local Helpers = MSK.Require.Load('@my_lib/client/helpers.lua')

-- Shorthand (callable module):
local Utils = MSK.Require('shared.utils')

MSK.Require.Json​

Reads and decodes a JSON file. The result is not cached, so edits to the file show up on the next call.

Parameters
path - string - Path of the JSON file

Returns
data - any - The decoded data

local data = MSK.Require.Json(path)

-- Example
local vehicles = MSK.Require.Json('data.vehicles') -- data/vehicles.json

MSK.Require.File​

Returns the raw contents of a file. The path is taken exactly as it is, no extension is added and dots are not turned into folders.

Parameters
path - string - Path of the file

Returns
content - string - The file contents

local content = MSK.Require.File(path)

-- Example
local html = MSK.Require.File('web/template.html')

MSK.Require.Unload​

Drops a cached Lua module, so the next Load runs the file again.

Parameters
path - string - Path of the Lua file

Returns
dropped - boolean - Whether the module was cached

local dropped = MSK.Require.Unload(path)
