epub format

[reeze]

Thank you for you excellect book.
Could you generate an epub version of the book, that will be really helpful for portability ;)

[sdiehl]

This was contributed by someone a while back:

https://github.com/sdiehl/write-you-a-haskell/blob/master/Makefile#L48

If you run

$ stac exec make epub

It should generate the file. I haven't really tested this much though.

Thanks!

it seems not working:

I am not sure what is the problem

[sdiehl]

You'll need to compile includes.hs

$ stack exec ghc includes.hs

[sdiehl]

Were you able to get it to build?

[reeze]

Hi,

➜  write-you-a-haskell git:(master) stack exec ghc includes.hs

includes.hs:4:8:
    Could not find module ‘Control.Monad.State’
    Perhaps you meant
      Control.Monad.ST (from base)
      Control.Monad.ST.Safe (from base)
      Control.Monad.Fix (from base)
    Use -v to see a list of the files searched for.

includes.hs:6:8:
    Could not find module ‘Text.Pandoc’
    Use -v to see a list of the files searched for.

includes.hs:10:8:
    Could not find module ‘Text.Pandoc.JSON’
    Use -v to see a list of the files searched for.

includes.hs:11:8:
    Could not find module ‘Text.Pandoc.Walk’
    Use -v to see a list of the files searched for.

Seems I need to install more libraries.

[sdiehl]

Does running stack build add the libraries you need?

:( I got this:

Seems related to this: haskell/cabal#2653

I changed ghc to 7.10, it works:

This should be now fixed on master with PR #75

[sdiehl]

Nice, I'll close.

thanks!
