Config Revamp

Featured Image for Config Revamp

This release brings several configuration fixes and improvements that will be especially useful for themes.

Deep merge of theme Params

One of the most common complaints from Hugo theme owners/users has been about the configuration handling. Hugo has up until now only performed a shallow merge of theme params into the configuration.

With that, given this example from a theme configuration:

[params]
[params.colours]
blue="#337DFF"
green="#68FF33"
red="#FF3358"

If you would like to use the above theme, but want a different shade of red, you earlier had to copy the entire block, even the colours you’re totally happy with. This was painful with even the simplest setup.

Now you can just override the params keys you want to change, e.g.:

[params]
[params.colours]
red="#fc0f03"

For more information, and especially about the way you can opt out of the above behaviour, see Merge Configuration from Themes.

Themes now support the config directory

Now both the project and themes/modules can store its configuration in both the top level config file (e.g. config.toml) or in the config directory. See Configuration Directory.

HTTP headers in getJSON/getCSV

getJSON now supports custom HTTP headers. This has been a big limitation in Hugo, especially considering the Authorization header.

We have updated the internal Instagram shortcode to pass the access token in a header:

{{ $hideCaption := cond (eq (.Get 1) "hidecaption") "1" "0" }}
{{ $headers := dict "Authorization" (printf "Bearer %s" $accessToken) }}
{{ with getJSON "https://graph.facebook.com/v8.0/instagram_oembed/?url=https://instagram.com/p/" $id "/&hidecaption=" $hideCaption $headers }}
    {{ .html | safeHTML }}
{{ end }}

Also see the discussion this issue about the access token above.

New erroridf template func

Sometimes, especially when creating themes, it is useful to be able to let the user decide if an error situation is critical enough to fail the build. The new erroridf produces ERROR log statements that can be toggled off:

{{ erroridf "some-custom-id" "Some error message." }}

Will log:

ERROR: Some error message.
If you feel that this should not be logged as an ERROR, you can ignore it by adding this to your site config:
ignoreErrors = ["some-custom-id"]

Notes

  • We now do deep merging of params from theme config(s). That is you most likely what you want, but Merge Configuration from Themes describes how you can get the old behaviour back.
