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.
Plain text readers are exposed to lua scripts via the `pandoc.reader`
submodule, which is further subdivided by format. Converting e.g. a
markdown string into a pandoc document is possible from within lua:
doc = pandoc.reader.markdown.read_doc("Hello, World!")
A `read_block` convenience function is provided for all formats,
although it will still parse the whole string but return only the first
block as the result.
Custom reader options are not supported yet, default options are used
for all parsing operations.
I think template haskell is robust enough now across platforms
that this will work.
Motivation: file-embed gives us better dependency tracking: if a data
file changes, ghc/stack/cabal know to recompile the Data module.
This also removes hsb2hs as a build dependency.
The 0.5.0 release of hslua fixes problems with lua C modules on linux.
The signature of the `loadstring` function changed, so a compatibility
wrapper is introduced to allow both 0.4.* and 0.5.* versions to be used.
* New module: Text.Pandoc.Writers.Ms.
* New template: default.ms.
* The writer uses texmath's new eqn writer to convert math
to eqn format, so a ms file produced with this writer
should be processed with `groff -ms -e` if it contains
math.
* Add `--lua-filter` option. This works like `--filter` but takes pathnames of special lua filters and uses the lua interpreter baked into pandoc, so that no external interpreter is needed. Note that lua filters are all applied after regular filters, regardless of their position on the command line.
* Add Text.Pandoc.Lua, exporting `runLuaFilter`. Add `pandoc.lua` to data files.
* Add private module Text.Pandoc.Lua.PandocModule to supply the default lua module.
* Add Tests.Lua to tests.
* Add data/pandoc.lua, the lua module pandoc imports when processing its lua filters.
* Document in MANUAL.txt.
This contains a list of strings that will be recognized by pandoc's
Markdown parser as abbreviations. (A nonbreaking space will
be inserted after the period, preventing a sentence space in
formats like LaTeX.)
Users can override the default by putting a file abbreviations
in their user data directory (`~/.pandoc` on *nix).
Closes#1905.
Removed stateChapters from ParserState.
Now we parse chapters as level 0 headers, and parts as level -1 headers.
After parsing, we check for the lowest header level, and if it's
less than 1 we bump everything up so that 1 is the lowest header level.
So `\part` will always produce a header; no command-line options
are needed.
+ Text.Pandoc.Writers.Shared
+ Text.Pandoc.Parsing
+ Text.Pandoc.Asciify
+ Text.Pandoc.Emoji
+ Text.Pandoc.ImageSize
[API change]
These are often helpful to people writing their own
reader or writer modules. Closes#3260.
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.
The App module provides a function that does a pandoc conversion,
based on option settings. The program (pandoc.hs) now does nothing
more than parse options and pass them to this function, which can
easily be used by other applications (e.g. a GUI wrapper).
The Opt structure has been further simplified.
API changes:
* New exposed module Text.Pandoc.App
* Text.Pandoc.Highlighting has been exposed.
* highlightingStyles has been moved to Text.Pandoc.Highlighting.
Removed writerDocbookVersion in WriterOptions.
Renamed default.docbook template to default.docbook4.
Allow docbook4 as an output format.
But alias docbook = docbook4.
* Text.Pandoc.Writers.HTML: removed writeHtml, writeHtmlString,
added writeHtml4, writeHtml4String, writeHtml5, writeHtml5String.
* Removed writerHtml5 from WriterOptions.
* Renamed default.html template to default.html4.
* "html" now aliases to "html5"; to get the old HTML4 behavior,
you must now specify "-t html4".
The type is implemented in terms of an underlying bitset
which should be more efficient.
API change: from Text.Pandoc.Extensions export Extensions,
emptyExtensions, extensionsFromList, enableExtension, disableExtension,
extensionEnabled.
* Remove exported module `Text.Pandoc.Readers.TeXMath`
* Add exported module `Text.Pandoc.Writers.Math`
* The function `texMathToInlines` now lives in `Text.Pandoc.Writers.Math`
* Export helper function `convertMath` from `Text.Pandoc.Writers.Math`
* Use these functions in all writers that do math conversion.
This ensures that warnings will always be issued for failed
math conversions.
Introduce a new module, Text.Pandoc.Free, with pure versions, based on
the free monad, of numerous IO functions used in writers and
readers. These functions are in a pure
Monad (PandocAction). PandocAction takes as a parameter the type of
IORefs in it. It can be aliased in individual writers and readers to
avoid this parameter.
Note that this means that at the moment a reader can only use one type
of IORef. If possible, it would be nice to remove this limitation.
So far this just reproduces capacity.
Later we'll be able to add features like warning
messages, dynamic loading of xml syntax definitions,
and dynamic loading of themes.
+ Removed Text.Pandoc.Readers.Docx.Fonts
+ Moved its code to texmath; we now use (from texmath 0.9)
Text.TeXMath.Unicode.Fonts
+ Use texmath 0.9 (currently from git).
+ Updated epub tests because texmath now handles more mathml.
We already lower-bound tagsoup at 0.13.7, which means we were always
running the compatibility layer (it was conditional on min value
0.13). Better to just use `lookupEntity` from the library directly, and
convert a string to a char if need be.
