lua

Overview ¶

Package lua exposes hex/events to Lua scripts as the "events" module.

local events = require("events")

events.emit("user.created", { id = 1, name = "alice" })
events.emit("app.ready")   -- no payload

v1 is emit-only. Subscribing from Lua ("events.on(...)") is a follow-up: cross-goroutine callbacks into an LState need careful serialisation (the LState is not thread-safe), and the REPL / scripting use cases don't need it yet. Go-side subscribers registered via app.On see Lua-emitted events immediately.
