0f857c457d Use a defined monadic stack in Pages to lift the MonadReader ambiguity and allow finishing to reimplement getText demo 2020-03-14 16:57:16 +01:00
40475a3093 Clean unneeded stuff separating the monadic type constraint from the actual monad stack used, one more step towrds MonadFail -> MonadError 2020-03-14 16:55:34 +01:00
a9d3e5d326 Clean unused dependencies from Map + use a more defined Monad for the Box Chunks instance, hoping we will be able to clear the whole stack someday and stop requiring that RoContext type, unboxing and reboxing the FontSet for no good 2020-03-14 16:27:56 +01:00

5b8d951516 WIP: Try about everything that's possible to try, OrderedMap or [(,)], try to decouple Box instance for Content and the one for Indexed Text, breaks getText… will probably require some advanced effect library, there seems to be a weird MonadReader conflict in the errors messages 2020-03-11 18:55:18 +01:00

7cef65d799 Fixed vicious bug introduced by 6096a1a237 (since follow is now automatic for references, it's not called explicitely but should in case of 'several' Content, which is an array of references, each of which should be expended) — TODO: add a unit test for that 2020-03-04 18:14:33 +01:00
