Gulp rigger and conditional statements?

Question

HTML

You need to underline active menu items, but since the project is built through Rigger, one header file is underlined on all pages. Thus, only one point is emphasized.
Is it possible to somehow set conditions so that, depending on the page, a certain menu item is underlined? For example, do it through parameters or something else.

Answer 1

Throw out gulp-rigger. Install gulp-nunjucks ( API ) . So it will be possible to make a task:

gulp.task('build:html', () => {
  return gulp.src('src/*.html')
    .pipe(nunjucks.compile())
    .pipe(gulp.dest('dist/'));
});

Answer 2

gulp-rigger used to be used for merging js and css, there are no options.
You need a template engine, pug, handlebars, etc.
Or you can explain that there is no backend, and there is nothing to highlight the desired item.
