Troubleshooting issue with problemMatcher in VSCode TypeScript compiler not functioning

I am looking for a problem matcher that can detect two types of issues:

  1. compilation problems related to TypeScript
  2. issues flagged by tslint

This feature seems to be causing trouble in one of my projects, although it functions properly in others. Below is the problem matcher configuration from the .vscode/tasks.json file:

"problemMatcher": [
    "$tsc",
    {
        "owner": "tslint",
        "fileLocation": "relative",
        "severity": "error",
        "pattern": {
            "regexp": "^ERROR:\\s*(.*\\.ts)\\[(\\d+), (\\d+)\\]: (.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "message": 4
        }
    }
]

Answer №1

It seems that the issues were not being detected because they had prefixes like browserify or tsify.

The problem was resolved with the following setup, which will now catch problems during regular tsc compilation, as well as browserify/tsify compilation and tslint:

"problemMatcher": [
    "$tsc",
    {
        "owner": "typescript",
        "fileLocation": ["relative", "${workspaceRoot}"],
        "pattern": {
            "regexp": "^TypeScript (warning|error): (.*)\\((\\d+),(\\d+)\\): (.*)$",
            "severity": 1,
            "file": 2,
            "line": 3,
            "column": 4,
            "message": 5
        }
    },
    {
        "owner": "tslint",
        "fileLocation": "relative",
        "severity": "error",
        "pattern": {
            "regexp": "^ERROR:\\s*(.*\\.ts)\\[(\\d+), (\\d+)\\]: (.*)$",
            "file": 1,
            "line": 2,
            "column": 3,
            "message": 4
        }
    }
]
