Expected Behaviour

I am not sure how you normally run your Lua application. But I am used to use the tasks feature of VS code, so I created a tasks.json with this content:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Run main",
            "type": "shell",
            "command": "./main.lua",   
            "problemMatcher": [
                "$lua"
            ]       
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

Normally such a task makes use of a problemMatcher which parses the tasks console output for problems and then highlight the code line that was affected. But there seems no problemMatcher to be defined by the plugin.

Actual Behaviour

No problemMatcher provided.

Reproduction steps

1. Create a tasks.json as given in "Expected Behaviour"
2. Crate a main.lua with an error such as "local i = 5 + "foo"
3. Run the task, the output shows something like

/usr/bin/lua: ./main.lua:3: attempt to add a 'number' with a 'string'
stack traceback:
        [C]: in metamethod 'add'
        ./main.lua:3: in main chunk
        [C]: in ?

See the main.lua, there is no highlight due to this error.

Es ist keine Quelldatei oder kein Test angegeben. Reproduziere das Problem mit der bereitgestellten tasks.json- und main.lua-Beispieldatei und untersuche anschließend, wie die VS Code-Erweiterung die Aufgabenintegration und problem matchers beiträgt. Das Ziel ist erreicht, wenn Lua-Laufzeitfehler aus der Aufgabenausgabe geparst werden und die betroffene main.lua-Zeile hervorgehoben wird.
