Re: [hakyll] Include a list of recent posts in the sidebar

[Jasper Van der Jeugt]

Hello Sam,

I think there are two possible solutions.

A first solution assumes you're not using the actual body of the post
in the sidebar. If this is the case, you can just create a list of
"fake items" which represent the posts. You can do that like this:

fakePosts :: Compiler [Item String]
fakePosts = do
identifiers <- getMatches "posts/*"
return [Item identifier "" | identifier <- identifiers]

Then, you can just apply templates to this list, all metadata will be
accessible. I think this is the easiest and most straightforward solution.

Alternatively, you can create two versions for each post page. This
tutorial [1] has more info on how to do that. Then, you use one
version for the sidebar and the other for the actual pages.

Let me know if you need more help with either solution.

Hope this helps,
Peace,
Jasper

Thank you. Looks like the most straightforward solution indeed, and it is usable in any MonadMetadata context, including Rules. I hadn't seen your answer before (I fixed my group parameters), and I resorted to a similar way of doing this.

Alternatively, you can create two versions for each post page. This
tutorial [1] has more info on how to do that. Then, you use one

Makes sense!

Thanks.
