How do you configure templating engines?

[micahgodbolt]

Ah! Finally found it. The directory has to be set like this:

var nunjucks = require('nunjucks');
nunjucks.configure('./templates', {watch: false})

I'm using nunjucks, and I'm facing the same issue. I found you can configure nunjucks and add filters globally:

nunjucks
  .configure({watch: false})
  .addFilter('stretch', function(str) {
    return str.split('').map(function(char) {
      var stretched = '', i = 0
      for (i; i < 5; i++) { stretched += char }
      return stretched
    }).join('').toLowerCase()
  })

Then you can use the filter normally in your templates:

{{ title|stretch }}

Sorry for the late reply, I've been a little busy. But yeah, as @grancalavera said, you can configure a global instance of the templating engine to solve this.

I'm doing something similar here, where I'm instantiating handlebars and passing it some partials, to be used later in metalsmith (or gulpsmith in this case). Let me know if that solves it for you!

(I'll also add this to the documentation for posterity btw, it hasn't really been properly documented.)

Thanks, I ended up using Swig and configuring it globally using swig.setDefaults({ cache: false });. But it's likely that not all templating engines support global config.

@Rowno Yeah that could be, I'll check it out. It needs to at least be documented, because I ran into this myself as well.

So depending on the outcome of this issue: tj/consolidate.js#203, it might indeed be a good idea to expose the consolidate.requires object.

Edit: Yeah, consolidate.requires needs to be exposed. Not all templating languages can be configured without it, as @Rowno suspected.

@ismay your link of https://github.com/superwolff/cape/blob/master/gulp/util/gulpsmith.js 404s now. I'm still struggling with nunjucks and extending directory. Is there a new home for that file?
