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...
Previously `\include` wouldn't work if the included file
contained, e.g., a begin without a matching end.
We've changed the Tok type so that it stores a full SourcePos,
rather than just a line and column. So tokens keeep track
of the file they came from. This allows us to use a simpler
method for includes, which doesn't require parsing the included
document as a whole.
Closes#3971.
Now all the guts of openURL have been put into openURL from
Class. openURL is now sensitive to stRequestHeaders in CommonState
and will add these custom headers when making a request.
It no longer looks at the USER_AGENT environment variable,
since you can now set the `User-Agent` header directly.
* In Options.HTMLMathMethod, the KaTeX contsructor now takes only
one string (for the KaTeX base URL), rather than two [API change].
* The default URL has been updated to the latest version.
* The autoload script is now loaded by default.
The pipe command is wrapped in a lua function, throwing a lua error if
the command returns with an error. A wrapper is needed as Haskell
functions exposed to lua may not throw lua errors due to limitations of
hslua.
The error handling is written such that a table can be returned as an
error object in the future. This is potentially useful when finer
control is required while catching the error in lua code. Current
limitations of hslua require error objects to be strings.
Now 'fetch' simply fetches content and mime type.
A new 'hashname' function is provided to get a filename based
on the sha1 hash of the contents and the mime type.
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`.
This is standard for lua scripts, and I see no reason
to depart from the standard here.
Also, "arg" is now pushed onto the stack before the script
is loaded. Previously it was not, and thus "PandocParameters"
was not available at the top level.
