Add RSS feed to blog

[cmeeren]

Not sure if this is the right place, but it would be great to have an RSS feed or similar for the Fable blog.

The blog is published from fable-compiler.github.io so probably it should be done there. Anyways, I have no idea about how to make the RSS feed so this feature should come through a PR (in a way that updates are done automatically) :)

[cmeeren]

Ok, I don't know either, so I'll leave this for someone else. :)

By the way, I think you can move issues between repos now. Should be a "Transfer issue (beta)" link at the bottom of the right sidebar. So you can move it to the correct repo if you want.

I cloned the repo to look at this the other day, but didn't make any progress... now I'm not the only one needing this I might take another look tonight

That'd be awesome @xdaDaveShaw. I do need to automatize a bit more the blogs (e.g. the index is still updated manually) so let me know if you need something and I can add it to the build script:

fable-compiler.github.io/src/Main.fs

	let reg = Regex(@"^\s*-\s*title\s*:(.+)\n\s*-\s*subtitle\s*:(.+)\n")
	let pageTitle, header, subheader = "Fable Blog", "Blog", "Read about latest Fable news"
	renderMarkdownFrom pageTitle Navbar.Blog header subheader "blog"
	(Node.path.join(Paths.BlogDir, "index.md")) (Node.path.join(Paths.DeployDir, "blog", "index.html"))

	let m = reg.Match(text)
	let header, subheader, text =

	then m.Groups.[1].Value.Trim(), m.Groups.[2].Value.Trim(), text.Substring(m.Index + m.Length)
	else header, subheader, text
	let targetPath = Node.path.join(Paths.DeployDir, "blog", blog.Replace(".md", ".html"))
	renderMarkdown pageTitle Navbar.Blog header subheader "blog" targetPath text
	printfn "Blog generated"
	let renderHomePage() =
	render
	{ Title = "Fable: JavaScript you can be proud of!"
	TargetPath = Node.path.join(Paths.DeployDir, "index.html")
	NavbarActivePage = Navbar.Home
	RenderBody = HomePage.renderBody }
	printfn "Home page generated"

Thanks, I'm starting from there...

It still needs a bit of work, I need to refactor the code a little, and I can't get the dates in the right format.
I might do another PR to update the latest version to see if there's help there.

Current WIP is here: https://github.com/xdaDaveShaw/fable-compiler.github.io/tree/feed

I was trying to do it in a way to not alter your workflow of publishing posts.

Once I get it finished a send a PR, and we can iterate on the workflow

[xdaDaveShaw]

It looks like I need to add RFC-1123 formatting (DateTime.ToString("r")) to Fable to get this to work - I'm sure there's a workaround, but it eludes me at the moment - How do I call date.toUtcString on an object?

I'll create a PR for the Fable changes to get this added, and then I'll have to update this Repo to Fable 2.2.* as part of this work (or would a separate PR be better?)

[xdaDaveShaw]

OK, I'm really struggling with Dates...

JavaScript has .toUTCString but that converts from your current local to UTC, so calling that on my +0100 machine, means I get a date for yesterday.

I think we might need to change the workflow to enable an RSS Feed.

Maybe using a format like Jekyll does at the top of the posts with the date it was published in UTC Format, instead of/as well as typing it into the Index.md

Or a real poor mans version is just to manually update a feed.xml file :)
