Process filename on render?

[allanberry]

Hi Lume,

Thank you for beautiful software. Really liking it so far.

So, I'm looking for a way to adjust filenames on render. I'd like to programmatically include a version number, ideally from my site's _data.yml file.

To explain, I am using a somewhat strange piece of software that allows me to host individual static assets, but they're not versioned. I'd like to know at a glance whether the assets I've uploaded are up to date. Hence the manual versioning.

Any suggestion how this might be accomplished?

For example, something like this might work (but doesn't because it's meant for extensions):

site.preprocess(
  ["*mah_folder_name*"],
  (page) => page.data.filename = page.src.path + "v1.2.3" + page.src.ext,
);

No worries if not, I'll write my own external postprocessor. But it would be cool to manage it all in one place.

Thanks.

To include the version in the url, you can use the url function. For example, create _data.js file in the folder containing the files do you want to rewrite:

// my-files/_data.js

const version = "v1.2.3";

export function url(page) {
  return `./${page.src.slug}${version}${page.src.ext}`
}

Whoa, that's perfect. Simpler than expected by far. Thank you!
