4aa84f4006 In rendering PandocParsecError, only print input at error location...
if the source name is `source` (i.e., the top level). Otherwise
results will be misleading, since what readM does is to look
up the source position of the error in the *original* input,
which may not match the input used by parseFromString or
in parsing from an included file.

Closes #3865.  Not a great fix, maybe there's something better
that could be done, but this should at least avoid misleading
messages.

c7e3c1ec17 Support for PDF generation via weasyprint and prince (#3909)
* Rename --latex-engine to --pdf-engine
* In `Text.Pandoc.Options.WriterOptions`, rename `writerLaTeXEngine` to `writerPdfEngine` and `writerLaTeXArgs` to `writerPdfArgs`.
 * Add support for `weasyprint` and `prince`, in addition to `wkhtmltopdf`, for PDF generation via HTML (closes #3906).
* `Text.Pandoc.PDF.html2pdf`: use stdin instead of intermediate HTML file

0feb7504b1 Rewrote LaTeX reader with proper tokenization.
This rewrite is primarily motivated by the need to
get macros working properly.  A side benefit is that the
reader is significantly faster (27s -> 19s in one
benchmark, and there is a lot of room for further
optimization).

We now tokenize the input text, then parse the token stream.

Macros modify the token stream, so they should now be effective
in any context, including math. Thus, we no longer need the clunky
macro processing capacities of texmath.

A custom state LaTeXState is used instead of ParserState.
This, plus the tokenization, will require some rewriting
of the exported functions rawLaTeXInline, inlineCommand,
rawLaTeXBlock.

* Added Text.Pandoc.Readers.LaTeX.Types (new exported module).
  Exports Macro, Tok, TokType, Line, Column.  [API change]
* Text.Pandoc.Parsing: adjusted type of `insertIncludedFile`
  so it can be used with token parser.
* Removed old texmath macro stuff from Parsing.
  Use Macro from Text.Pandoc.Readers.LaTeX.Types instead.
* Removed texmath macro material from Markdown reader.
* Changed types for Text.Pandoc.Readers.LaTeX's
  rawLaTeXInline and rawLaTeXBlock.  (Both now return a String,
  and they are polymorphic in state.)
* Added orgMacros field to OrgState.  [API change]
* Removed readerApplyMacros from ReaderOptions.
  Now we just check the `latex_macros` reader extension.
* Allow `\newcommand\foo{blah}` without braces.

379b99f63a Added writerEpubSubdirectory to WriterOptions.
[API change]

The EPUB writer now takes its EPUB subdirectory from this option.

Also added `PandocEpubSubdirectoryError` to `PandocError`.
This is raised if the EPUB subdirectory is not all ASCII
alphanumerics.

See #3720.

cd2551c16c Added PandocResourceNotFound error.
Use this instead of PandocIOError when a resource is not
found in path.

This improves the error message in this case, see #3629.

913db947a9 Text.Pandoc.App: Throw errors rather than exiting.
These are caught (and lead to exit) in pandoc.hs, but
other uses of Text.Pandoc.App may want to recover in another
way.

Added PandocAppError to PandocError (API change).
This is a stopgap:  later we should have a separate constructor
for each type of error.

Also fixed uses of 'exit' in Shared.readDataFile, and
removed 'err' from Shared (API change).

Finally, removed the dependency on extensible-exceptions.

See #3548.

5e1249481b Added Text.Pandoc.Logging (exported module).
This now contains the Verbosity definition previously
in Options, as well as a new LogMessage datatype that
will eventually be used instead of raw strings for
warnings.

This will enable us, among other things, to provide
machine-readable warnings if desired.

See #3392.

d7583f3659 Error: change type of handleError.
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.

be4783109c Fix out of index error in handleError
In the latex parser when includes are processed, the text of the
included file is directly included into the parse stream. This caused
problems when there was an error in the included file (and the included
file was longer than the original file) as the error would be reported
at this position.

The error handling tries to display the line and position where the
error occured. It works by including a copy of the input and finding the
place in the input when given the position of the error. In the
previously described scenario, the input file would be the original
source file but the error position would be the position of the error in
the included file.

The fix is to not try to show the exact line when it would cause an
out-of-bounds error.

c423dbb5a3 Use -XNoImplicitPrelude and 'import Prelude' explicitly.
This is needed for ghci to work with pandoc, given that we
now use a custom prelude.
