[Question] Import-blacklist by regex does not work as expected

[alxpsr]

Question

• TSLint version: 5.15.0
• TypeScript version: 3.4.3
• Running TSLint via: CLI / VSCode

TypeScript code being linted

import { SecondaryService } from "./src";
export class BasicService {
    public State: boolean;

    constructor(public s: SecondaryService) {

    }
}

with tslint.json configuration:

{
    "defaultSeverity": "error",
    "extends": [
        "tslint:recommended"
    ],
    "jsRules": {},
    "rules": {
        "import-blacklist": [
            true,
            "^.*src$",
        ]
    },
    "rulesDirectory": []
}

Actual behavior

Tslint does not emit any errors

Expected behavior

string import { SecondaryService } from "./src"; should mark as wrong by import-blacklist regex rule

Questions

• What im doing wrong?
• How can i disallow importing from import-blacklist regex patterns?

[JoshuaKGoldberg]

Solution: wrap any regular expressions in arrays. ["^.*src$"] instead of "^.*src$".

This isn't described well in the documentation; accepting PRs to explicitly mention this!

{
    "defaultSeverity": "error",
    "jsRules": {},
    "rules": {
        "import-blacklist": [
            true,
            ["^.*src$"]
        ]
    },
    "rulesDirectory": []
}

{
    "defaultSeverity": "error",
    "jsRules": {},
    "rules": {
        "import-blacklist": [
            true,
            ["^.*src$"]
        ]
    },
    "rulesDirectory": []
}

doesn't match on organisation names like @mylib/thing/src

@alshdavid Could you find a solution by now? I have exactly the same issue right now with ["^.*@app/bkh.*"].

[alshdavid]

No solution, sadly
