VSCode TypeScript problemMatcher not working

Question

I desire a problem matcher which reports two kinds of problems:

1. typescript compilation problems
2. tslint problems

This isn't working in one of my projects, but is working in others. Here is the problem matcher line from the .vscode/tasks.json :

"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

I believe the problems weren't being picked up, because they were being prefixed by browserify or tsify .

The following configuration solved the problem, and should report problems for regular tsc compilation, 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
        }
    }
]
