之前我写了一篇 在 LuaJIT 中调用 AHK（旧），本来我不打算这么用，只为了验证功能，所以草草了事。但后来我感觉还是有一定的实用性，所以又把代码完善了一下，新增了许多功能。

安装方法

我已将代码发布到 GitHub（https://github.com/goreliu/luajit-ahk）。

首先从 https://hotkeyit.github.io/v2/ 下载 v1 版本，根据自己的 LuaJIT 版本，把 Win32w 或 x64w 目录下的 AutoHotkey.dll 放入 lua51.dll 所在目录，vcruntime140.dll 可能也需要。

然后直接运行 ahk_demo.lua 即可，也可以将其放入 LuaJIT 能找到的地方使用。

另外可以用 luarocks install luajit-ahk 安装（不包含 AutoHotkey.dll）。

使用方法

local ahk = require 'ahk'

-- init()
ahk.init()

-- exec()
ahk.exec('MsgBox, exec test')

ahk.exec([[
    a := 333
    b := "getVar test"
]])

-- setVar()
ahk.setVar('b', 'getVar new test')

-- getVar()
print(ahk.getVar('a'))
ahk.exec('MsgBox, ' .. ahk.getVar('b'))

ahk.exec([[
Fun(Text) {
    MsgBox, % Text
    return Text
}

return

La:
    MsgBox, label test
    return
]])

-- func()
print(ahk.func('Fun', 'func test'))

-- label()
print(ahk.label('La'))

-- addScript()
ahk.addScript('MsgBox, addScript test', true)

-- execLine()
pLine = ahk.addScript('MsgBox, execLine test')
print(ahk.execLine(pLine, 3, true))

-- C()
local L = require 'utf8fix'.L
ahk.C().ahkExec(L'MsgBox, C test')

-- initWithText()
ahk.initWithText('#Persistent\nMsgbox, initWithText test %1%', nil, 'abc')

ahk.exec('Sleep, 2000')
