Unable to specify multiple plugins in the PostCSS options map

[jmooring]

Our PostCSS options documentation states:

use [string]
List of PostCSS plugins to use

Currently you can only specify a single plugin:

• The use element of the options map will not accept a slice of plugins; it expects a string
• If you specify a list of plugins as you would using the postcss-cli, it treats the list as a single string

For example, neither of these work:

{{ $css := resources.Get "css/main.css" | postCSS (dict "use" (slice "autoprefixer" "postcss-color-alpha")) }}
{{ $css := resources.Get "css/main.css" | postCSS (dict "use" "autoprefixer postcss-color-alpha") }}

You can work around this by (a) creating a postcss configuration file, or (b) creating a postcss object within the project's package.json file.

But for simple setups, with just a few plugins using default plugin options, specifying the plugins inline is simpler.
