This should help with #3979.
In my test, I got a data uri for data-background. But it didn't
actually work in the browser (the background image didn't show).
Not sure whether this is a problem in reveal.js or a problem
in pandoc...
Removed `writerSourceURL` from `WriterOptions` (API change).
Added `stSourceURL` to `CommonState`.
It is set automatically by `setInputFiles`.
Text.Pandoc.Class now exports `setInputFiles`, `setOutputFile`.
The type of `getInputFiles` has changed; it now returns `[FilePath]`
instead of `Maybe [FilePath]`.
Functions in Class that formerly took the source URL as a parameter
now have one fewer parameter (`fetchItem`, `downloadOrRead`,
`setMediaResource`, `fillMediaBag`).
Removed `WriterOptions` parameter from `makeSelfContained` in
`SelfContained`.
We also export the set of known `schemes`.
The new function replaces the function of the same name
from `Network.URI`, as the latter did not check whether a scheme is
well-known. E.g. MediaWiki wikis frequently feature pages with names
like `User:John`. These links were interpreted as URIs, thus turning
internal links into global links. This is prevented by also checking
whether the scheme of a URI is frequently used (i.e. is IANA registered
or an otherwise well-known scheme).
Fixes: #2713
Update set of well-known URIs from IANA list
All official IANA schemes (as of 2017-05-22) are included in the set of
known schemes. The four non-official schemes doi, isbn, javascript, and
pmid are kept.
Closes#3629.
However, there is still room for improvement.
`@import` with following media declaration is not
handled.
Also `@import` with a simple filename (rather than
`url(...)` is not handled.
This can happen e.g. with an @import of a google web font.
(What is imported is some CSS which contains an url reference
to the font itself.)
Also, allow unescaped pipe (|) in URL.
This is intended to help with #3629, but it doesn't seem to
work.
You can leave an external link as it is by adding the attribute
data-external="1" to the element. Pandoc will then not try to
incorporate its content when `--self-contained` is used. This is
similar to a feature already supported by the EPUB writer.
Closes#2656.
Instead, just use script or style tags with the content inside.
The old method with data URIs prevents certain optimizations
outside pandoc.
Exception: data URIs are still used when a script contains
`</script>` or a style contains `</`.
Closes#3423.
Also, in MIME, use application/javascript (not
application/x-javascript).
- 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.
In 1b44acf0c5 we replaced some
hackish CSS parsing with css-text, which I thought was a complete
CSS parser. It turns out that it is very buggy, which results
in lots of things being silently dropped from CSS when
`--self-contained` is used (#2224).
This commit replaces the use of css-text with a small but
more principled css preprocessor, which only removes whitespace
and replaces URLs with base 64 data when possible.
Closes#2224.
* Create a type synonym for MIME type (instead of `String`).
* Add `getMimeTypeDef` function.
* Avoid recreating MIME type `Map`s every time.
* Move “Formula-...” case handling into `getMimeType`.
* mkSelfContained now takes just two arguments, WriterOptions and
the string.
* It no longer looks in data files. This only made sense when we
had copies of slidy and S5 code there.
* Shared.fetchItem' is used instead of the nearly duplicate getItem.
Moved `MediaBag` definition and functions from Shared:
`lookupMedia`, `mediaDirectory`, `insertMedia`, `extractMediaBag`.
Removed `emptyMediaBag`; use `mempty` instead, since `MediaBag`
is a Monoid.
* In Shared, openURL and fetchItem now return an Either, for
better error handling. (API change.)
* Better error message when fetching a URL fails with
`--self-contained`.
* EPUB writer: If resource not found, skip it, as in Docx writer.
* Closes#916.
