非原生lua环境下的调试

1. 不兼容lua原生的-e命令的环境

如果能修改兼容-e命令,在环境中执行指定lua代码段,请转到下面

可以在lua脚本中直接attach来连接调试器即可. 如果lua脚本中不支持加载动态库的,可以有使用以下方法:

导出lua符号表

导出lua符号表的比较简单,可以使用attach或者launch来挂载调试器

---

{
    "name": "launch process",
    "request": "launch",
    "runtimeArgs": "${workspaceFolder}/main.lua",
    "runtimeExecutable": "${workspaceFolder}/aa.exe",
    "stopOnEntry": true,
    "type": "lua",
    "inject": "lldb", //根据平台使用lldb/gdb/hook,主要为了注入launch动态库来挂载调试器
    "luaVersion": "5.1",
}

---

{
    "name": "attach",
    "processName": "lua", //或者使用processid
    "request": "attach",
    "stopOnEntry": true,
    "type": "lua",
    "inject": "lldb",
}

未导出lua符号表

2. 兼容lua原生-e命令的环境

以下以busted测试框架为例

{
    "type": "lua",
    "request": "launch",
    "name": "Debug",
    "program": "${workspaceFolder}/t/save-database.lua",
    "luaexe": "resty",
    "luaArch": "arm64",
    "luaVersion": "jit",
    "path": "${workspaceFolder}/?.lua",
    "cpath": "${workspaceFolder}/?.so"
}

主要设置luaexe,luaArch,luaVersion三个参数即可.
