Error expected variable end

[Paxa]

I'm trying to call some function inside {{ }} and it gives error.

I was trying to print current year:

{{ new Date().getFullYear() }}

How to do it right?

You can call functions, but you can't run arbitrary JS code (so no new), and you can't access arbitrary JS globals, only values you explicitly pass into the template context (so no Date unless you pass it in yourself). You can pass new Date() explicitly into the template context when rendering; if you give it the name now (just as an example) you could then do {{ now.getFullYear() }} in the template.

I use Gulp with Nunjucks. My solution is appending the year value to the data passing to the context.

var data = require('./templates/data.json');
data.year = new Date().getFullYear();

gulp.task('nunjucks', () =>
  gulp.src('templates/*.njk')
    .pipe(nunjucks.compile(data), options)
    .pipe(rename(function (path) {
      path.extname = ".html";
    }))
    .pipe(gulp.dest(''))
);

Then in the layout.njk file I can directly use the year value

<div class="copyright">&copy; {{ year }}</div>

Output in the index.html file

<div class="copyright">&copy; 2017</div>
