A metatable in Lua defines various extraneous behaviors for a table when indexed, modified, interacted with, etc. They are Lua's core metaprogramming feature; most well known for being useful to emulate classes much like an OOP language.

Any table (and userdata) may be assigned a metatable. You can define a metatable for a table as such:

-- Our sample table
local tab = {}
-- Our metatable
local metatable = {
 -- This table is then what holds the metamethods or metafields

Terminal Spec: Synchronized Output

This page has moved!

Please see here: contour-terminal/vt-extensions

Synchronized Output

Synchronized output is merely implementing the feature as inspired by iTerm2 synchronized output, except that it's not using the rare DCS but rather the well known SM ? and RM ?. iTerm2 has now also adopted to use the new syntax instead of using DCS.
