As an example:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
{{ $pages := .Site.RegularPages | lang.Merge $frSite.RegularPages | lang.Merge $enSite.RegularPages }}
|
||
|
|
```
|
||
|
|
|
||
|
|
Will "fill in the gaps" in the current site with, from left to right, content from the French site, and lastly the English.
|
||
|
|
|
||
|
|
|
||
|
|
A more practical example is to fill in the missing translations for the "minority languages" with content from the main language:
|
||
|
|
|
||
|
|
|
||
|
|
```bash
|
||
|
|
{{ $pages := .Site.RegularPages }}
|
||
|
|
{{ .Scratch.Set "pages" $pages }}
|
||
|
|
{{ $mainSite := .Sites.First }}
|
||
|
|
{{ if ne $mainSite .Site }}
|
||
|
|
{{ .Scratch.Set "pages" ($pages | lang.Merge $mainSite.RegularPages) }}
|
||
|
|
{{ end }}
|
||
|
|
{{ $pages := .Scratch.Get "pages" }}
|
||
|
|
```
|
||
|
|
|

Note that the slightly ugly `.Scratch` construct will not be needed once this is fixed: https://github.com/golang/go/issues/10608
