This is needed for ghci to work with pandoc, given that we
now use a custom prelude.
Closes #2503.
|
|
- 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.

I've messed up badly with it, so it didn't work properly most of the
time. At the plus side, fallback mechanic is working wonderfully.

This allows inherited styles with numbering (lists). It works like this:
1. check to see if the style has numbering info.
2. if the paragraph has explicit numbering info in the doc that takes
precedence.
3. if not we use the numbering info in the style, if it's there.
4. otherwise normal paragraph.
We no longer assume it's not a numbering element if it doesn't have an
explicit level---we just set that level to 1. (In the style files, the
examples I've seen don't have that explicit level.)

Some older versions of word use vml (vector markup language) and put
their images in a "v:imagedata" tag inside a "w:pict". We read those as
we read the more modern "blip" inside a "w:drawing".
Note that this does not mean the reader knows anything about vml. It
just looks for a `v:imagdata`. It's possible that, with more complicated
uses of images in vml, it won't do the right thing.

Previously, if a URL had an anchor, such as
http://johnmacfarlane.net/pandoc/README.html#synopsis
the reader would incorrectly identify it as an internal link
and return "#synopsis" for the link in output.

This patch builds paragraph styles tree, then checks if paragraph has
style.styleId or style/name.val matching predetermined patterns.
Works with "Heading#" (name.val="heading #") for headings and
"Quote"|"BlockQuote"|"BlockQuotation" (name.val="Quote"|"Block Text")
for block quotes.

Fix path-slashes inside archive for windows
|
|
When users number their headers, Word understands that as a single item
enumerated list. We make the assumption that such a list is, in fact, a header.
|
|
Don't use os-sensitive "combine", since we always want the paths in our
zip-archive to use forward-slashes.
|
|
Two points here: (1) We're going bottom-up, from styles not based on
anything, to avoid circular dependencies or any other sort of
maliciousness/incompetence. And (2) each style points to its
parent. That way, we don't need the whole tree to pass a style over to
Docx.hs
|
|
|
|
This will make it easier to build the style map from the bottom up (to
avoid any infinite references).
|
|
We want to be able to read user-defined styles. Eventually we'll be able
to figure out styles in terms of inheritance as well. The actual
cascading will happen in the docx reader.
|

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.
