The lua filters and custom lua writer system defined very similar
StackValue instances for strings and tuples. These instance definitions
are extracted to a separate module to enable sharing.
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.
