There are two states in PandocPure, but it is only easy to deal with
CommonState. In the past, to do state monad operations on
PureState (the state specific to PandocPure) you had to add (lift
. lift) to the monadic operation and then rewrap in the newtype. This
adds four functions ({get,gets,put,modify}PureState) corresponding to
normal state monad operations. This allows the user to modify
PureState in PandocPure without worrying about where it sits in the
monad stack or rewrapping the newtype.
It now lives in IO and gives a proper message + exit
instead of calling 'error'.
We shouldn't be making it easier for people to raise error on
pure code. And this is better for the main application
in IO.
* Removed handleIncludes from LaTeX reader [API change].
* Now the ordinary LaTeX reader handles includes in a way
that is appropriate to the monad it is run in.
* Renaming Text.Pandoc.Class.warn to addWarning avoids conflict
with Text.Pandoc.Shared.warn.
* Removed writeRTFWithEmbeddedImages from Text.Pandoc.Writers.RTF.
This is no longer needed; we automatically handle embedded images
using the PandocM functions. [API change]
* Remove exported module `Text.Pandoc.Readers.TeXMath`
* Add exported module `Text.Pandoc.Writers.Math`
* The function `texMathToInlines` now lives in `Text.Pandoc.Writers.Math`
* Export helper function `convertMath` from `Text.Pandoc.Writers.Math`
* Use these functions in all writers that do math conversion.
This ensures that warnings will always be issued for failed
math conversions.
This is to enable macros in T2T, but can be used for other stuff in the
future, I imagine.
This requires building up the info in our fake file trees. Note the
version in IO is safe.
This will be unified with Text.Pandoc.Error eventually. But I'm building
it out here so as not to interfere with other modules that might be
using the error module currently.
Right now, the io warnings both print to stderr and write to the
state. That can be easily modified.
We also add a getWarnings function which pulls warnings out of the state
for instances of PandocMonad.
