Asynchronous Lua scripts

myGPIOd reads on startup the folder defined by lua_async_dir. Each file with the extension .lua is loaded and registered as Lua file. This files can be called with the lua_async action.

Note

These Lua scripts are executed in a new thread and therefore do not have access to data structures from the main thread. Use this type of scripts for longer running actions.

Custom lua functions

myGPIOd registers custom lua functions to provide access to the actions. The functions return true on success, else false as first value.

Lua function	Description
local rc, resp_header, resp_body = http({method}, {uri}, {content-type}, {postdata})	Submits a HTTP request and waits for the response. Set content-type and postdata to nil if no body should be sent. Valid HTTP methods are: DELETE, GET, HEAD, OPTIONS, PATCH, POST, PUT

Example lua file

local rc, resp_header, resp_body = http("GET", "http://test.lan/", nil, nil)
print(resp_body)
