Nunjucks: disabling cache doesn't work

[jvolker]

I'm trying to use metalsmith-layouts with metalsmith-watch and watch the source and template directories.

.use(
    watch({
      paths: {
        ["./source/**/*"] : true, // every changed files will trigger a rebuild of themselves 
        ["./template/**/*"] : "**/*" // every templates changed will trigger a rebuild of all files
      },
      livereload: true
    })
)

Whenever I change my main template file home.njk the browser refreshes satisfyingly.

However I'm also using Nunjucks' include tag to pull in template partials. Nunjucks by default caches files being included. Whenever I change one of these files the change is not visible in the browser, even after a refresh. When I run the whole build script again, the change is visible.

I tried passing cache: false in the metalsmith-layouts configuration. But it does not have any effect.

Thanks!

As a workaround I'm now doing the following:

var nunjucks = require('nunjucks');

nunjucks.configure('./template', {
  watch: true,
  noCache : true
});

.use(layouts({
  engine: 'nunjucks',
  requires: {
    "nunjucks" : nunjucks
  },
  directory: './template/',
  _partials: 'partials/',
})

I can then use includes like this:

{% include _partials + "head.njk" %}

That could be. Whether passing cache: false does anything is determined by consolidate. It handles the caching, and might not clear the cache for nunjucks templates, see here. I'd suggest you to check there, as we're dependent on the way consolidate handles this.

Let me know if anything related to layouts pops up.
