API changes: Text.Pandoc.Options:
* Added Verbosity.
* Added writerVerbosity.
* Added readerVerbosity.
* Removed writerVerbose.
* Removed readerTrace.
pandoc CLI: The `--trace` option sets verbosity to DEBUG;
the `--quiet` option sets it to ERROR, and the `--verbose`
option sets it to INFO. The default is WARNING.
Signature of pipeProcess has changed: the return value is
now IO (ExitCode, ByteString) -- with only stdout. Stderr
is just inherited from the parent.
This means that stderr from filters will now be streamed
as the filters are run.
Closes#2729.
Since PandocMonad is an instance of MonadError, this will allow us, in a
future commit, to change all invocations of `error` to `throwError`,
which will be preferable for the pure versions. At the moment, we're
disabling the lua custom writers (this is temporary).
This requires changing the type of the Writer in Text.Pandoc. Right now,
we run `runIOorExplode` in pandoc.hs, to make the conversion easier. We
can switch it to the safer `runIO` in the future.
Note that this required a change to Text.Pandoc.PDF as well. Since
running an external program is necessarily IO, we can be clearer about
using PandocIO.
Instead, emit the alt text, emphasized. This accords with what
the ODT writer currently does.
The user will still get a warning about a nonexistent image,
but will no longer get a LaTeX crash.
Closes#3100.
Variables margin-top, margin-bottom, margin-left, margin-right.
Setting them with css inside @page doesn't seem to work, at least
with the released wkhtmltopdf.
* Bumped version to 1.16.
* Added Attr field to Link and Image.
* Added `common_link_attributes` extension.
* Updated readers for link attributes.
* Updated writers for link attributes.
* Updated tests
* Updated stack.yaml to build against unreleased versions of
pandoc-types and texmath.
* Fixed various compiler warnings.
Closes#261.
TODO:
* Relative (percentage) image widths in docx writer.
* ODT/OpenDocument writer (untested, same issue about percentage widths).
* Update pandoc-citeproc.
Don't use custom prelude for latest ghc.
This is a better approach to making 'stack ghci' and 'cabal repl'
work. Instead of using NoImplicitPrelude, we only use the custom
prelude for older ghc versions. The custom prelude presents a
uniform API that matches the current base version's prelude.
So, when developing (presumably with latest ghc), we don't
use a custom prelude at all and hence have no trouble with ghci.
The custom prelude no longer exports (<>): we now want to
match the base 4.8 prelude behavior.
- 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.
Closes#2067.
EPS can't be supported without shelling out to something like
ImageMagick, but at least we can avoid mysterious error messages.
We now get:
pandoc: Unable to convert `circle.eps' for use with pdflatex.
! Package pdftex.def Error: File `circle-eps-converted-to.pdf' not found.
which seems more straightforward.
Fixes compile error on Windows for 5040f3e
Reverted back to canonical file separators </> in all places except for
arguments to the LaTeX builder and in TEXINPUTS
See #1151.
Note: Temporary directories still fail to be removed in Windows due to
call of ByteString.Lazy.readFile creating process ownership of the
compiled pdf file.
This is needed for texlive.
Note that the / is used only in the body of withTempDir,
so when the directory is deleted, the original separators will
be used.
See #1151.
Previously we used to store the directory of the first input file,
even if it was local, and used this as a base directory for
finding images in ODT, EPUB, Docx, and PDF.
This has been confusing to many users. It seems better to look for
images relative to the current working directory, even if the first
file argument is in another directory.
writerSourceURL is set to 'Just url' when the first command-line
argument is an absolute URL. (So, relative links will be resolved
in relation to the first page.) Otherwise, 'Nothing'.
The ODT, EPUB, Docx, and PDF writers have been modified accordingly.
Note that this change may break some existing workflows. If you
have been assuming that relative links will be interpreted relative
to the directory of the first file argument, you'll need to
make that the current directory before running pandoc.
Closes#942.
* `Text.Pandoc.PDF` exports `makePDF` instead of `tex2pdf`.
(API change.)
* `makePDF` walks the pandoc AST and checks for the existence of
images in the local directory. If they are not found, it attempts
to find them, either in the directory containing the first source
file, or at an absolute URL, or at a URL relative to the base URL
of the first command line argument.
* Closes#917.
