2021-10-22Lua: marshal Pandoc values as userdataAlbert Krewinkel2-11/+36
2021-10-22Switch to hslua-2.0Albert Krewinkel23-1115/+1013
The new HsLua version takes a somewhat different approach to marshalling and unmarshalling, relying less on typeclasses and more on specialized types. This allows for better performance and improved error messages. Furthermore, new abstractions allow to document the code and exposed functions.
2021-10-12Revert "Depend on pandoc-types 1.23, remove Null constructor on Block."John MacFarlane1-0/+2
This reverts commit fb0d6c7cb63a791fa72becf21ed493282e65ea91.
2021-10-01Depend on pandoc-types 1.23, remove Null constructor on Block.John MacFarlane1-2/+0
2021-08-24Text.Pandoc.Class: add readStdinStrict method to PandocMonad.John MacFarlane1-0/+1
[API change]
2021-08-24Lua subsystem and custom writers: generalize types from PandocIO...John MacFarlane2-6/+4
to any instance of PandocMonad and MonadIO. This involves an API change, since the type of runLua is now (PandocMonad m, MonadIO m) => Lua a -> m (Either PandocError a)
2021-06-10Lua utils: fix handling of table headers in `from_simple_table`Albert Krewinkel1-1/+1
Passing an empty list of header cells now results in an empty table header. Fixes: #7369
2021-05-24MediaBag improvements.John MacFarlane1-3/+3
In the current dev version, we will sometimes add a version of an image with a hashed name, keeping the original version with the original name, which would leave to undesirable duplication. This change separates the media's filename from the media's canonical name (which is the path of the link in the document itself). Filenames are based on SHA1 hashes and assigned automatically. In Text.Pandoc.MediaBag: - Export MediaItem type [API change]. - Change MediaBag type to a map from Text to MediaItem [API change]. - `lookupMedia` now returns a `MediaItem` [API change]. - Change `insertMedia` so it sets the `mediaPath` to a filename based on the SHA1 hash of the contents. This will be used when contents are extracted. In Text.Pandoc.Class.PandocMonad: - Remove `fetchMediaResource` [API change]. Lua MediaBag module has been changed minimally. In the future it would be better, probably, to give Lua access to the full MediaItem type.
2021-04-08Lua filter: respect Inlines/Blocks filter functions in pandoc.walk_*Albert Krewinkel2-3/+10

2021-02-27Lua: use strict evaluation when retrieving AST value from the stackAlbert Krewinkel1-79/+77
Fixes: #6674
2021-02-04Lua filters: use same function names in Haskell and LuaAlbert Krewinkel2-28/+30
2021-02-02Lua: add module "pandoc.path"Albert Krewinkel1-0/+2
The module allows to work with file paths in a convenient and platform-independent manner. Closes: #6001 Closes: #6565
2021-01-26Lua: always load built-in Lua scripts from default data-dirAlbert Krewinkel4-46/+44
The Lua modules `pandoc` and `pandoc.List` are now always loaded from the system's default data directory. Loading from a different directory by overriding the default path, e.g. via `--data-dir`, is no longer supported to avoid unexpected behavior and to address security concerns.
2021-01-08Update copyright notices for 2021 (#7012)Albert Krewinkel24-34/+34
2020-12-16Support Lua marshalling of doctemplates BoolVal.John MacFarlane1-0/+1
This updates T.P.Lua.Marshaling.Context for doctemplates >= 0.9.
2020-11-07Lint code in PRs and when committing to master (#6790)Albert Krewinkel1-1/+1
* Remove unused LANGUAGE pragmata * Apply HLint suggestions * Configure HLint to ignore some warnings * Lint code when committing to master
2020-10-14Fix typos in comments, doc strings, error messages, and testsAlbert Krewinkel1-1/+1
Typos reported by https://fossies.org/linux/test/pandoc-master.tar.gz/codespell.html See: #6738
2020-09-20Lua filters: add SimpleTable for backwards compatibility (#6575)Albert Krewinkel5-7/+106
A new type `SimpleTable` is made available to Lua filters. It is similar to the `Table` type in pandoc versions before 2.10; conversion functions from and to the new Table type are provided. Old filters using tables now require minimal changes and can use, e.g., if PANDOC_VERSION > {2,10,1} then pandoc.Table = pandoc.SimpleTable end and function Table (tbl) tbl = pandoc.utils.to_simple_table(tbl) … return pandoc.utils.from_simple_table(tbl) end to work with the current pandoc version.
2020-09-13Fix hlint suggestions, update hlint.yaml (#6680)Christian Despres2-6/+3
* Fix hlint suggestions, update hlint.yaml Most suggestions were redundant brackets. Some required LambdaCase. The .hlint.yaml file had a small typo, and didn't ignore camelCase suggestions in certain modules.
2020-07-25Lua filters: make attr argument optional in Table constructorAlbert Krewinkel1-1/+1
This changes the Lua API. It is highly unlikely for this change to affect existing filters, since the documentation for the new Table constructor (and type) was incomplete and partly wrong before. The Lua API is now more consistent, as all constructors for elements with attributes now take attributes as the last parameter.
2020-05-12Lua: fix regression in package searcherAlbert Krewinkel1-2/+8
This caused `require 'module'` to fail for third party packages. Fixes: #6361
2020-04-28Support new Underline element in readers and writers (#6277)Vaibhav Sagar1-0/+2
Deprecate `underlineSpan` in Shared in favor of `Text.Pandoc.Builder.underline`.
2020-04-17API change: use new type PandocLua for all pandoc Lua operationsAlbert Krewinkel7-204/+241
The new type `PandocLua` is an instance of the `PandocMonad` typeclass and can thus be used in a way similar to `PandocIO`.
2020-04-17API change: use PandocError for exceptions in Lua subsystemAlbert Krewinkel9-35/+175
The PandocError type is used throughout the Lua subsystem, all Lua functions throw an exception of this type if an error occurs. The `LuaException` type is removed and no longer exported from `Text.Pandoc.Lua`. In its place, a new constructor `PandocLuaError` is added to PandocError.
2020-04-15Lua: support new tablesAlbert Krewinkel1-17/+99
2020-04-15Use the new builders, modify readers to preserve empty headersdespresc1-1/+2
The Builder.simpleTable now only adds a row to the TableHead when the given header row is not null. This uncovered an inconsistency in the readers: some would unconditionally emit a header filled with empty cells, even if the header was not present. Now every reader has the conditional behaviour. Only the XWiki writer depended on the header row being always present; it now pads its head as necessary.
2020-04-15Adapt to the newest Table type, fix some previous adaptation issuesdespresc2-11/+34
- Writers.Native is now adapted to the new Table type. - Inline captions should now be conditionally wrapped in a Plain, not a Para block. - The toLegacyTable function now lives in Writers.Shared.

2020-03-29Clean up some fmaps (#6226)Joseph C. Sible1-1/+1
* Avoid fmapping when we're just binding right after anyway * Clean up unnecessary fmaps in the LaTeX reader
2020-03-22Finer grained imports of Text.Pandoc.Class submodules (#6203)Albert Krewinkel7-9/+14
This should speed-up recompilation after changes in `Text.Pandoc.Class`, as the number of modules affected by a change will be smaller in general. It also offers faster insights into the parts of `T.P.Class` used within a module.
2020-03-15Use implicit Prelude (#6187)Albert Krewinkel19-36/+0
* Use implicit Prelude The previous behavior was introduced as a fix for #4464. It seems that this change alone did not fix the issue, and `stack ghci` and `cabal repl` only work with GHC 8.4.1 or newer, as no custom Prelude is loaded for these versions. Given this, it seems cleaner to revert to the implicit Prelude. * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary. * Always use custom prelude Previously, the custom prelude was used only with older GHC versions, as a workaround for problems with ghci. The ghci problems are resolved by replacing package `base` with `base-noprelude`, allowing for consistent use of the custom prelude across all GHC versions.
2020-03-13Update copyright year (#6186)Albert Krewinkel18-26/+26
* Update copyright year * Copyright: add notes for Lua and Jira modules

2020-02-07Apply linter suggestions. Add fix_spacing to lint target in Makefile.John MacFarlane2-2/+0
2020-02-07Resolve HLint warningsAlbert Krewinkel2-2/+1
All warnings are either fixed or, if more appropriate, HLint is configured to ignore them. HLint suggestions remain. * Ignore "Use camelCase" warnings in Lua and legacy code * Fix or ignore remaining HLint warnings * Remove redundant brackets * Remove redundant `return`s * Remove redundant as-pattern * Fuse mapM_/map * Use `.` to shorten code * Remove redundant `fmap` * Remove unused LANGUAGE pragmas * Hoist `not` in Text.Pandoc.App * Use fewer imports for `Text.DocTemplates` * Remove redundant `do`s * Remove redundant `$`s * Jira reader: remove unnecessary parentheses
2020-01-15Lua filters: allow filtering of element lists (#6040)Albert Krewinkel3-29/+114
Lists of Inline and Block elements can now be filtered via `Inlines` and `Blocks` functions, respectively. This is helpful if a filter conversion depends on the order of elements rather than a single element. For example, the following filter can be used to remove all spaces before a citation: function isSpaceBeforeCite (spc, cite) return spc and spc.t == 'Space' and cite and cite.t == 'Cite' end function Inlines (inlines) for i = #inlines-1,1,-1 do if isSpaceBeforeCite(inlines[i], inlines[i+1]) then inlines:remove(i) end end return inlines end Closes: #6038

2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc8-32/+38
PR #5884. + Use pandoc-types 1.20 and texmath 0.12. + Text is now used instead of String, with a few exceptions. + In the MediaBag module, some of the types using Strings were switched to use FilePath instead (not Text). + In the Parsing module, new parsers `manyChar`, `many1Char`, `manyTillChar`, `many1TillChar`, `many1Till`, `manyUntil`, `mantyUntilChar` have been added: these are like their unsuffixed counterparts but pack some or all of their output. + `glob` in Text.Pandoc.Class still takes String since it seems to be intended as an interface to Glob, which uses strings. It seems to be used only once in the package, in the EPUB writer, so that is not hard to change.
2019-10-29Changes to build with new doctemplates/doclayout.John MacFarlane1-4/+6
The new version of doctemplates adds many features to pandoc's templating system, while remaining backwards-compatible. New features include partials and filters. Using template filters, one can lay out data in enumerated lists and tables. Templates are now layout-sensitive: so, for example, if a text with soft line breaks is interpolated near the end of a line, the text will break and wrap naturally. This makes the templating system much more suitable for programatically generating markdown or other plain-text files from metadata.
2019-10-09Options.WriterOptions: Change type of writerVariables to Context Text.John MacFarlane2-0/+32
This will allow structured values. [API change]
2019-09-29Raise error on unsupported extensions. Closes #4338.John MacFarlane1-10/+15
+ An error is now raised if you try to specify (enable or disable) an extension that does not affect the given format, e.g. `docx+pipe_tables`. + The `--list-extensions[=FORMAT]` option now lists only extensions that affect the given FORMAT. + Text.Pandoc.Error: Add constructors `PandocUnknownReaderError`, `PandocUnknownWriterError`, `PandocUnsupportedExtensionError`. [API change] + Text.Pandoc.Extensions now exports `getAllExtensions`, which returns the extensions that affect a given format (whether enabled by default or not). [API change] + Text.Pandoc.Extensions: change type of `parseFormatSpec` from `Either ParseError (String, Extensions -> Extensions)` to `Either ParseError (String, [Extension], [Extension])` [API change]. + Text.Pandoc.Readers: change type of `getReader` so it returns a value in the PandocMonad instance rather than an Either [API change]. Exceptions for unknown formats and unsupported extensions are now raised by this function and need not be handled by the calling function. + Text.Pandoc.Writers: change type of `getWriter` so it returns a value in the PandocMonad instance rather than an Either [API change]. Exceptions for unknown formats and unsupported extensions are now raised by this function and need not be handled by the calling function.
2019-09-08Replace Element and makeHierarchical with makeSections.John MacFarlane3-40/+5
Text.Pandoc.Shared: + Remove `Element` type [API change] + Remove `makeHierarchicalize` [API change] + Add `makeSections` [API change] + Export `deLink` [API change] Now that we have Divs, we can use them to represent the structure of sections, and we don't need a special Element type. `makeSections` reorganizes a block list, adding Divs with class `section` around sections, and adding numbering if needed. This change also fixes some longstanding issues recognizing section structure when the document contains Divs. Closes #3057, see also #997. All writers have been changed to use `makeSections`. Note that in the process we have reverted the change c1d058aeb1c6a331a2cc22786ffaab17f7118ccd made in response to #5168, which I'm not completely sure was a good idea. Lua modules have also been adjusted accordingly. Existing lua filters that use `hierarchicalize` will need to be rewritten to use `make_sections`.
2019-08-16Lua: improve function documentationsAlbert Krewinkel1-1/+4
2019-08-16Lua: traverse nested blocks and inlines in correct orderAlbert Krewinkel2-11/+24
Traversal methods are updated to use the new Walk module such that sequences with nested Inline (or Block) elements are traversed in the order in which they appear in the linearized document. Fixes: #5667
2019-08-16Lua: add module for AST element sequence traversalAlbert Krewinkel1-0/+112
Lua filters must be able to traverse sequences of AST elements and to replace elements by splicing sequences back in their place. Special `Walkable` instances can be used for this; those are provided in a new module `Text.Pandoc.Lua.Walk`.
2019-07-02Fix redundant constraint warnings. (#5625)Pete Ryland2-2/+2
2019-06-23Update Lua function names in pandoc.systemniszet1-2/+2
Fixed function names of pandoc.system.get_working_directory() and pandoc.system.with_temporary_directory() which are written in the manual of lua filter.
2019-06-12Lua: add a `clone()` method to all AST elements (#5572)Albert Krewinkel2-1/+50
