How to use

Needs .vscode/launch.json on workspace.

Configurations

Launch

"rqeuest"="launch"
runtimeExecutable: the path to executable
cwd: working directory
arg: arguments for executable
name: debug instance name, shown on vscode debug pannel, can distinguish between attach debuggers
encoding: optional, encoding of variables

Attach

"rqeuest"="attach"
cwd: working directory
name: debug instance name
encoding: optional, encoding of variables

It needs to pick a progress when starts attach debugging

{workspaceFolder}can be used in configuring cwd and runtimeExecutable, it means current opening work space

for example

.vscode\launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lua",
            "name": "Debug MainServ",
            "request": "launch",
            "cwd": "${workspaceFolder}\\Server",
            "runtimeExecutable": "${workspaceFolder}\\Server\\main.exe",
            "arg": "-n MainServ -f"
        },
        {
            "type": "lua",
            "name": "AttachMainServ",
            "request": "attach",
            "cwd": "${workspaceFolder}\\Server"
        },
        {//only name has different, for distinguish
            "type": "lua",
            "name": "AttachDBServ",
            "request": "attach",
            "cwd": "${workspaceFolder}\\Server"
        }
    ]
}

build

needsluamaketo compile bee.lua
andvs2019 or higher

switch directory tobee.lua and run

luamake

this command builds x64 version luadebug, if wants to build x86 version, add --arch x86 after the command. If you have previously compiled for other architectures, remember to delete the build directory under the bee.lua directory
use vscode openlauncherandLuaInject, then run build and thenluadebug.exe、launcher.dllandLuaInject.dll whill copy to bin。
Remember to choose the right platform(x86/x64)
Run Run Extension on vscode

Project structure

The project has three parts：vscode extension(src directory)、Debug Adapater(script directory)、LuaInject(LuaInject directory)

vscode extension part configures extension and registersDebug Dapater
Debug Adapter handles the messages between vscode extension and LuaInject
LuaInject injects to lua program，do the real debugging and breakpoints

bee.lua starts Debug Adapter, and supports some useful library, apart from that, it just launch main.lua on bin doc supports code completion for scripts
launcher project provides methods to launch program and inject LuaInject, and channles to communicate to LuaInject
libs provides libs

Startup

vscode runs Debug Adapter(bin/$arch/luadebug.exe), and do some initializes, then vscode sends launch command with configurations writting on launch.json. Debug Adapter uses methods provided bylauncher to launch target progress and inject LuaInject.dll to hook lua functions. After that, vscode sends breakpoint configurations and starts debugging.
More details about the process onOverview，The protocol betweenDebug Adapter and vscode isDebug Adapter Protocol，read and write on stdout。
