I produce my responsive images with gulp. In that gulpfile.js I have variables like `small = 320`, `medium = 768` and `large = 1200` which are used by the `gulp-responsive` plugin.

It would be great if I could read those values into a `partial/srcset.html` for implementing the correct images attributes like `suffix` or `w`.

Currently I have those values in `data/srcset.toml` from where I can bring them in the partial. But I have to maintain 2 sources.

Any idea?

```auto
process.env.SMALL = small

```

And then in template

```html
{{ $small := getenv "SMALL" }}

```

A related tip:

```auto
process.env.HUGO_BASEURL = "https://example.com"

```
