Create multiple pages out of one source file

[Stephan Schiffels]

Hi.

I have a data file listing data for items. I would like to generate multiple pages from that one source file. 

Right now I simply read the source file outside of Hakyll, and then use it from inside the Rules Monad. But I think it would be nicer to have it all inside Hakyll for consistency.

So instead of doing something like

main :: IO ()

main = parseDataFile "data/myData.json" >>= runHakyll

runHakyll :: [(String, MyData)] -> Rules ()

runHakyll listOfData = hakyll $ do

    create (map fst data) $ do

       -- this will create one page per item in data

       ...

I would like to do 

main = hakyll $ do

    match "data/myData.json" $ do

       rawStr <- getResourceString

       let data = parse ... rawStr

       return data

create (map fst data) $ do

    -- this won't work because I would have to "load" the data, which is only possible in the Compiler Monad, not in the Rules Monad.

Is there a best practice for something like this? I looked at "makeItem", but that is weird because it associates the newly created items with the one identifier used in the Rules. As far as I can see, I cannot create new identifiers once I am in the Compiler.

So there is the following dilemma:

- loading compiled data is only possible within Compiler, not Rules

- Creating new identifiers is only possible within Rules, not Compiler.

Any help would be appreciated.

Thanks, Stephan
