Remote debugging?

[iandol]

@CppCXY recommended I open a new issue from LuaLS/lua-language-server#2951

In Zerobrane Studio Mobdebug works really well and is easy to setup (luarocks install mobdebug and turn remote server on in GUI, add these to script md=require("mobdebug") and then md.start()). I've previously used VSCode-Mobdebug, but it is not actively developed and is not stable. I've tried LuaHelper with LuaPanda but prefer to LuaLS.

How can I setup remote debugging. I added the EmmyLua debug configurations, and also require("emmy_core") in my target lua script. But running "emmylua new Debug" I get this error:

The other debug config "Attach by Program" does not seem to support remote debugging?

My require("emmy_core") also fails, what is the procedure to install it?

macOS M2, latest VS Code, lua 5.4.7 and luarocks installed using homebrew

[CppCXY]

press: command + shift + p and search emmy:

this will insert some code like:

package.cpath = package.cpath .. ";c:/User/Path/to/emmy_core/?.dll"
local dbg = require("emmy_core")
dbg.tcpListen("localhost", 9966)

you can add more code for debug:

dbg.waitIDE()
dbg.breakHere()

You need to run the Lua script first and then run the debug configuration, or use a task to start the corresponding Lua program.

OK, that is working thanks! Will you accept a pull request with these instructions in case future users would like to get set up?

Of course, if you are willing.

What is the difference between dbg.waitIDE() and dbg.breakHere()?

[CppCXY]

dbg.waitIDE means to pause execution and wait for the IDE to connect, dbg.breakHere means to force a break at this point.

[iandol]

So the first time we always need to use use dbg.waitIDE, then for subsequent breaks we only need dbg.breakHere?

It's not like that, not all debugging needs involve debugging the startup code., it depends on the requirements. The EmmyLua debugger is non-blocking by default for this reason.

[iandol]

OK, but at least for remote debugging dbg.waitIDE() is always required? Anyway, see #181

EDIT: oh you merged already, thanks!
