Lots of cleanups here:
- Refactor InterfaceToConfig and InterfaceToFrontMatter to use io.Writer.
- Simplify InterfaceToFrontMatter by wrapping InterfaceToConfig.
- Export FrontmatterType since we return it in DetectFrontMatter.
- Refactor removeTOMLIdentifier to avoid blindly replacing "+++".
- Update HandleJSONMetaData to return an empty map on nil input.
- Updates vendored goorgeous package and test for org-mode frontmatter.
- Add tests and godoc comments.
Coverage for parser package increased from 45.2% to 85.2%.
Previously this was left empty, but it is very handy to have a list
of term pages for a given taxonomy. This list can now be paginated
like other page lists. It makes it possible to render summary
content from each terms index page for instance. It also makes it
possible to sort the term pages in the same way that other page
lists can be sorted. An RSS feed is now generated for
KindTaxonomyTerm pages as well.
This also fixes a bug in HugoSites.createMissingPages. Previously
it would only check for existing KindTaxonomyTerm pages if the
taxonomy had any terms defined. So for a taxonomy with no terms
but a taxonomy terms page it would generate a second empty terms
page.
This relates to #3123.
The interfaces and types in `target` made sense at some point, but now this package is too restricted to a hardcoded set of media types.
The overall current logic:
* Create a file path based on some `Translator` with some hardcoded logic handling uglyURLs, hardcoded html suffix etc.
* In in some cases (alias), a template is applied to create the alias file.
* Then the content is written to destination.
One could argue that it is the last bullet that is the actual core responsibility.
This commit fixes that by moving the `hugolib`-related logic where it belong, and simplify the code, i.e. remove the abstractions.
This code will most certainly evolve once we start on #3123, but now it is at least possible to understand where to start.
Fixes #3123
