In docx, super- and subscript are attributes of Vertalign. It makes more
sense to follow this, and have different possible values of Vertalign in
runStyle. This is mainly a preparatory step for real style parsing,
since it can distinguish between vertical align being explicitly turned
off and it not being set.
In addition, it makes parsing a bit clearer, and makes sure we don't do
docx-impossible things like being simultaneously super and sub.

The big news here is a rewrite of Docx to use the builder
functions. As opposed to previous attempts, we now see a significant
speedup -- times are cut in half (or more) in a few informal tests.
Reducible has also been rewritten. It can doubtless be simplified and
clarified further. We can consider this, at the moment, a reference for
correct behavior.

Note that "Italic" can be on, and, from the last commit, `<w:i>` can be
present, but be turned off. In that case, the turned-off tag takes
precedence. So, we have to distinguish between something being off and
something not being there. Hence, isItalic, isBold, isStrike, and
isSmallCaps have become Maybes.
|
|
Before we just checked for the existence of a tag. Now, we make sure to
check for its on/off value.

Introduces a new function in Reducibles, concatR. The idea is that if we
have two list of Reducibles (blocks or inlines), we can combine them and
just perform the reduction on the joining parts (the last element of the
first list, the first element of the second list). This is useful in cases
where the two lists are already reduced, and we're only worried about the
joining elements.
This actually improves the efficiency a bit further, because concatR can be
smart about empty lists.

Docx reader: Fix spacing issue.

Previously spaces at the beginning of Emph/Strong/etc were kept
inside. This makes sure they are moved out.

This changes the signature of the exported `readOMML` to `String ->
Either String [Exp]`, so it can now, in theory, be slotted into
TeXMath. It doesn't have any real error reporting yet, but that might
make more sense once I put it in a branch, and understand how it works
in the other readers.
It also now reads strings that parse to either oMath or oMathPara
elements. Note that the distinction is lost in the output. It's up to
the caller to remember the display type.
|
|
This gets rid of commented-out functions, cleans up whitespace errors,
and exports and imports the correct functions.
|
|
We still need to test against prefixes, but this is only going to look
at oMath fragments, so we're not going to be worried about looking up
the real namespace.
|
|
This is the first step in removing the intermediate OMath type, which we
no longer need since we're writing straight to TeXMath Exp.

Previous drawings that were under some other toplevel run (i.e., a
hyperlink) wouldn't be properly handled. This should fix that.
|
|
|
|
Could use some cleanup, but this is the first step for getting
an OMML reader into TeXMath.
|
|
TeXMath does the work now.
|
|
|
|
The new version of TeXMath can translate from its type system into
LaTeX. So instead of writing the LaTeX ourself, we write to the TeXMath
`Exp` type, and let TeXMath do the rest.

The parser had been changing footnotes and endnotes into footnotes. This
isn't a problem, because pandoc collapses them, but the parser should
maintain as much of the docx structure as is collapsed, and let the
toplevel reader worry about how to translate it into Pandoc. (This would
be an issue when, as is planned, the docx parser spins off into its
own module.)
The output is the same, so no test change is required.
|
|
Image data will not be put in a media bag map, which will be output
along with the pandoc output.

mtl switched from ErrorT to ExceptT, but we're not sure which mtl we'll
be dealing with. This should make errors work with both.
The main difference (beside the name of the module and the monad
transformer) is that Except doesn't require an instance of an Error
Typeclass. So we define that for compatability. When we switch to a
later mtl, using Control.Monad.Exception, we can just erase the instance
declaration, and all should work fine.
|
|
This modifies the Docx type in the parser to avoid all the extra files
(Notes, numbering, etc). A reader monad keeps track of these, and applies
them at the end. The reader monad is stacked with ErrorT to enable better
error-handling than the old Maybes. (Note that the better error handling
isn't really there yet, but it is now possible.)
One long-term goal of these changes is to make it easier to write the Docx
type. This should make it easier to develop a standalone docx package in the
future.

This will allow us to deal with unicode characters from word equations. This
part of the process will need to continue to be improved.
|

|
|
This lets us keep more information about the indentation, and act
accordingly in the reader.
|
|
Remove some redundant ways of dealing with Maybe.
|
|
mapMaybe does the filtering for us.
|
|
This is just for the Parse module, reading it into the Docx format. It
still has to be translated into pandoc.
|
|
Insertion and deletion. Dates are just strings for now.
|
|
|
|
This will allow us to get rid of more general functions we no longer need in
the main reader.
|
|
This defines a typeclass `Reducible` which allows us to "reduce" pandoc
Inlines and Blocks, like so
Emph [Strong [Str "foo", Space]] <++> Strong [Emph [Str "bar"]], Str
"baz"] =
[Strong [Emph [Str "foo", Space, Str "bar"], Space, Str "baz"]]
So adjacent formattings and strings are appropriately grouped.
Another set of operators for `(Reducible a) => (Many a)` are also
included.
