Debugging doesn't start

[arykovanov]

There is nothing happens when I trying to debug lua file.
Debuging panel appears for a moment and disappear.
Neither debug nor run happens.

I have created a 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": [
        {
            "name": "lua_current",
            "type": "lua",
            "request": "launch",
            "stopOnEntry": true,
            "program": "${file}",
            "cwd": "${workspaceFolder}",
            "path": "${workspaceFolder}/?.lua",
            "cpath": "${workspaceFolder}/?.dll",
            "arg": [],
            "consoleCoding": "utf8"
        },
    ]
}

There is an error in console:

Add "console": "internalConsole" to launch.json and try again.

[arykovanov]

I'am sorry but don't know what should change after adding 'internalConsole' where to look.
I have added 'internalConsole'. Have found these logs in the 'Log(ExtensionHost')

In the console from Developer Tools I see next messages. One of which 'SIGPIPE' every time I start debug session.

BTW. Everything happens on Ubuntu.

It may be that lua-debug is not working.You can refer to the readme and recompile it.

[arykovanov]

You are right.
Recompiled luadebug on my machine and put into .vscode/extension. After that it again started to debug.

[cefn]

I hit this same issue and had to follow roughly the following steps from a blank debian install to populate a folder in the location ~/.vscode/extensions/lua-debug which finally correctly debugged a lua program. My environment is debian buster running as a linux container within Chrome OS but would probably work for any modern debian or ubuntu.

First uninstall the Marketplace version of the Lua Debug package, then...

Install some lua

sudo apt install lua5.3

Install some versioning, compiling, making tools

sudo apt install build-essential clang libreadline-dev git ninja-build

Check out and build luamake

cd ~
git clone https://github.com/actboy168/luamake
cd luamake
git submodule update --init --recursive
ninja -f ninja/linux.ninja

Check out and build lua-debug

cd ~
git clone https://github.com/actboy168/lua-debug.git
cd lua-debug
git submodule update --init --recursive
../luamake/luamake

Copy the resulting 'publish' folder to your vscode extensions folder as lua-debug

cd ~/lua-debug
cp publish ~/.vscode/extensions/lua-debug

Restart VSCode and find that lua-debug is now running and debugging code. My example working launch.json looks like...

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lua",
            "request": "launch",
            "name": "Debug",
            "program": "${workspaceFolder}/example.lua"
        }
    ]
}
