how ro call tslint with parameter using gulp-tslint ?

[sirentek]

gulp-tslint version: 8.1.2
tslint version: 5.6
Operating system: Windows10

Example gulpclass.ts task:

import * as tslint from 'gulp-tslint';
.....

  @Task()
  private analyseTypescript() {
    let options = { 
      summarizeFailureOutput: true 
    };

    return gulp.src(['./src/**/*.ts', '!**/*.d.ts', '!node_modules/**'])
      .pipe(tslint.default())
      .pipe(tslint.default.report(options));
  }

Console output:
Warning: The 'no-use-before-declare' rule requires type information.

adding type-check parameter in command line solves it:
tslint --type-check --project tslint.json
=>Warning goes away.

how could we add type-check parameter in gulp-tslint ?
I couldn't find a similar example..

Thanks!

Usually the project configuration (--project) is tsconfig.json, whereas tslint.json is (obviously) the tslint configuration (--config).

Anyway, you just need to add another pipe:

.pipe(tslint({program: require("tslint").Linter.createProgram("./tsconfig.json")}))
