This implements RSS timeline generation in gmnhg.
RSS is generated both for the whole site, and for the content
directories as an rss.xml file inside these directories.
RSS requires the absolute URI to the article. For this to work,
a geminiBaseURL setting is required to be set in the Hugo
configuration file (config.toml/json/yaml).
RSS template can be ovewritten on the site-wide /
directory-wise basis; see godoc on how to do this.
As there's no discovery method of an RSS timeline in Gemini,
the users are expected to put a link to rss.xml on their site
where necessary.
With Hugo, a page bundle can be skipped from rendering if
it specifies headless = true in its front matter. This makes
gmnhg properly skip these pages from rendering.
Fixes#11.
This makes the Go compiler automatically calculate renderer
flags bitmask values by putting 1 << iota as the first meaningful flag.
This has a downside of having the first flag always meaning 2, and not
1, whereas WithMetadata already meaned 1, therefore this is a breaking
change.
This changes gomarkdown parser behavior to allow code blocks, lists, etc
to come after other blocks (like paragraphs) and get processed as
independent blocks without a separate newline (putting gomarkdown in
charge to decide whether a new block is started).
This is a breaking change as this affects how some existing Markdown
source might get rendered. Nonetheless, this is probably the expected
default by most users. This has no configurable switch yet.
See #14.
gmnhg is the new program that generates a Gemini site from Hugo site
content. It reads its input from content/, static/, and layouts/gmnhg/.
Its output by default goes to output/.
More doc is available in the program doc header.
This also introduces a simple program, md2gmn, that is meant for testing
the renderer on Markdown files. Nonetheless, it can be used as
a standalone tool as well.
