Don't use custom prelude for latest ghc.
This is a better approach to making 'stack ghci' and 'cabal repl'
work. Instead of using NoImplicitPrelude, we only use the custom
prelude for older ghc versions. The custom prelude presents a
uniform API that matches the current base version's prelude.
So, when developing (presumably with latest ghc), we don't
use a custom prelude at all and hence have no trouble with ghci.
The custom prelude no longer exports (<>): we now want to
match the base 4.8 prelude behavior.
- The (non-exported) prelude is in prelude/Prelude.hs.
- It exports Monoid and Applicative, like base 4.8 prelude,
but works with older base versions.
- It exports (<>) for mappend.
- It hides 'catch' on older base versions.
This allows us to remove many imports of Data.Monoid
and Control.Applicative, and remove Text.Pandoc.Compat.Monoid.
It should allow us to use -Wall again for ghc 7.10.
This function is equivalent to the more general (<*) which is defined in
Control.Applicative. This change makes pandoc code easier to understand for
those not familar with the codebase.
Previously these were typeclasses of monads. They've been changed
to be typeclasses of states. This ismplifies the instance definitions
and provides more flexibility.
This is an API change! However, it should be backwards compatible
unless you're defining instances of HasReaderOptions, HasHeaderMap,
or HasIdentifierList. The old getOption function should work as
before (albeit with a more general type).
The function askReaderOption has been removed.
extractReaderOptions has been added.
getOption has been given a default definition.
In HasHeaderMap, extractHeaderMap and updateHeaderMap have been added.
Default definitions have been given for getHeaderMap, putHeaderMap,
and modifyHeaderMap.
In HasIdentifierList, extractIdentifierList and updateIdentifierList
have been added. Default definitions have been given for
getIdentifierList, putIdentifierList, and modifyIdentifierList.
The ultimate goal here is to allow different parsers to use their
own, tailored parser states (instead of ParserState) while still
using shared functions.
