LTUI

A cross-platform terminal ui library based on Lua

Introduction (中文)

LTUI is a cross-platform terminal ui library based on Lua.

This framework originated from the requirements of graphical menu configuration in xmake. Similar to the linux kernel's menuconf to configure the compilation parameters, so using curses and lua to implement a cross-platform character terminal ui library.

Refer to kconfig-frontends for style rendering. Of course, users can customize different ui styles.

Installation

$ luarocks install ltui

Build

We need install the cross-platform build utility xmake first.

$ xmake

Run tests

We need install lua or luajit to run tests first.

$ xmake run test dialog
$ xmake run test window
$ xmake run test desktop
$ xmake run test inputdialog
$ xmake run test mconfdialog

Or

$ lua tests/dialog.lua
$ lua tests/window.lua
$ lua tests/desktop.lua
$ lua tests/inputdialog.lua
$ lua tests/mconfdialog.lua

Or

$ luajit tests/dialog.lua
$ luajit tests/window.lua
$ luajit tests/desktop.lua
$ luajit tests/inputdialog.lua
$ luajit tests/mconfdialog.lua

Examples

Application

local ltui        = require("ltui")
local application = ltui.application
local event       = ltui.event
local rect        = ltui.rect
local window      = ltui.window
local demo        = application()

function demo:init()
    application.init(self, "demo")
    self:background_set("blue")
    self:insert(window:new("window.main", rect {1, 1, self:width() - 1, self:height() - 1}, "main window", true))
end

demo:run()

Label

local lab = label:new("title", rect {0, 0, 12, 1}, "hello ltui!"):textattr_set("white")

Button

local btn = button:new("yes", rect {0, 1, 7, 2}, "< Yes >"):textattr_set("white")

Input dialog

function demo:init()
    -- ...

    local dialog_input = inputdialog:new("dialog.input", rect {0, 0, 50, 8})
    dialog_input:text():text_set("please input text:")
    dialog_input:button_add("no", "< No >", function (v) dialog_input:quit() end)
    dialog_input:button_add("yes", "< Yes >", function (v) dialog_input:quit() end)
    self:insert(dialog_input, {centerx = true, centery = true})
end
