2020-04-17API change: use new type PandocLua for all pandoc Lua operationsAlbert Krewinkel3-89/+58
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 Krewinkel1-8/+11
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.
2020-03-29Clean 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 Krewinkel3-4/+6
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 Krewinkel5-8/+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 * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary.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 Krewinkel5-5/+5
* Update copyright year * Copyright: add notes for Lua and Jira modules
2020-02-07Resolve HLint warningsAlbert Krewinkel1-1/+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
2020-01-04Add type annotations to assist ghci.John MacFarlane1-3/+4
2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc3-21/+22
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.
2019-09-29Raise 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 MacFarlane2-9/+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: traverse nested blocks and inlines in correct orderAlbert Krewinkel1-2/+3
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
2019-07-02Fix redundant constraint warnings. (#5625)Pete Ryland1-1/+1
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 Krewinkel1-0/+46
Closes: #5568
2019-05-29pandoc.mediabag module: add function `delete`Albert Krewinkel1-1/+7
Function `pandoc.mediabag.delete` allows to remove a single item of the given name from the media bag.
2019-05-29pandoc.mediabag module: add function `empty`Albert Krewinkel1-0/+6
Function `pandoc.mediabag.empty` was added. It allows to clean-out the media bag, removing all entries.
2019-05-29pandoc.mediabag module: add items function iterating over mediabagAlbert Krewinkel1-1/+7
A new function `pandoc.mediabag.items` was added to Lua module pandoc.mediabag. This allows users to lazily iterate over all media bag items, loading items into Lua one-by-one. Example: for filename, mime_type, content in pandoc.mediabag.items() do -- use media bag item. end This is a convenient alternative to using `mediabag.list` in combination with `mediabag.lookup`.
2019-05-29Lua: add Version type to simplify comparisonsAlbert Krewinkel2-0/+30
Version specifiers like `PANDOC_VERSION` and `PANDOC_API_VERSION` are turned into `Version` objects. The objects simplify version-appropriate comparisons while maintaining backward-compatibility. A function `pandoc.types.Version` is added as part of the newly introduced module `pandoc.types`, allowing users to create version objects in scripts.
2019-05-04Lua: add `pandoc.system` module (#5468)Albert Krewinkel1-0/+34
The `system` Lua module provides utility functions to interact with the operating- and file system. E.g. print(pandoc.system.get_current_directory()) or pandoc.system.with_temporary_directory('tikz', function (dir) -- write and compile a TikZ file with pdflatex end)
2019-03-01Remove license boilerplate.John MacFarlane3-51/+0
The haddock module header contains essentially the same information, so the boilerplate is redundant and just one more thing to get out of sync.
2019-02-16T.P.Lua: split StackInstances into smaller Marshaling modulesAlbert Krewinkel3-3/+3
2019-02-16T.P.Lua: get CommonState from Lua globalAlbert Krewinkel1-25/+41
This allows more control over the common state from within Lua scripts.
2019-02-04Add missing copyright notices and remove license boilerplate (#5112)Albert Krewinkel3-6/+6
Quite a few modules were missing copyright notices. This commit adds copyright notices everywhere via haddock module headers. The old license boilerplate comment is redundant with this and has been removed. Update copyright years to 2019. Closes #4592.
2018-11-19Lua filters: test AST object equality via HaskellAlbert Krewinkel1-3/+15
Equality of Lua objects representing pandoc AST elements is tested by unmarshalling the objects and comparing the result in Haskell. A new function `equals` which performs this test has been added to the `pandoc.utils` module. Closes: #5092
2018-11-17Lua Utils module: improve stringifyAlbert Krewinkel1-2/+9
Meta value strings (MetaString) and booleans (MetaBool) are now converted to the literal string and the lowercase boolean name, respectively. Previously, all values of these types were converted to the empty string.
2018-09-24Use hslua v1.0.0Albert Krewinkel3-27/+27
2018-08-12Lua: cleanup Lua utils, remove unused functions.Albert Krewinkel1-4/+5
2018-07-30Lua Utils module: add function blocks_to_inlines (#4799)Albert Krewinkel1-0/+10
Exposes a function converting which flattenes a list of blocks into a list of inlines. An example use case would be the conversion of Note elements into other inlines.
2018-03-18Use NoImplicitPrelude and explicitly import Prelude.John MacFarlane3-0/+6
This seems to be necessary if we are to use our custom Prelude with ghci. Closes #4464.
2018-01-23Lua filters: store constructors in registryAlbert Krewinkel1-1/+1
Lua functions used to construct AST element values are stored in the Lua registry for quicker access. Getting a value from the registry is much faster than getting a global value (partly to idiosyncrasies of hslua); this change results in a considerable performance boost.
2018-01-15Renaming: Json -> JSON in modules and functions.John MacFarlane1-5/+5
2018-01-13Lua modules: add function pandoc.utils.run_json_filterAlbert Krewinkel1-3/+26
Runs a JSON filter on a Pandoc document.
2018-01-05Update copyright notices to include 2018Albert Krewinkel3-6/+6
2018-01-04Use hslua utils where possibleAlbert Krewinkel3-17/+16
Some helper functions and types have been moved to hslua. Change: minor
2018-01-01Lua.Module.Utils: make stringify work on MetaValues.John MacFarlane1-1/+4
I'm sure this was intended in the first place, but currently only Meta is supported.
2017-12-23Lua modules: add function pandoc.utils.hierarchicalizeAlbert Krewinkel1-7/+12
Convert list of Pandoc blocks into (hierarchical) list of Elements.
2017-12-23Lua modules: add function pandoc.utils.normalize_dateAlbert Krewinkel1-2/+10
The function parses a date and converts it (if possible) to "YYYY-MM-DD" format.
2017-12-23Lua modules: add function pandoc.utils.to_roman_numeralAlbert Krewinkel1-1/+9
The function allows conversion of numbers below 4000 into roman numerals.
2017-12-22Lua modules: add stringify function to pandoc.utilsAlbert Krewinkel1-6/+35
The new function `pandoc.utils.stringify` converts any AST element to a string with formatting removed.
2017-12-21Lua modules: added pandoc.utils moduleAlbert Krewinkel2-8/+50
A new module `pandoc.utils` has been created. It holds utility functions like `sha1`, which was moved from the main `pandoc` module.
2017-12-21Lua modules: make a Haskell module for each Lua moduleAlbert Krewinkel2-72/+110
Definitions for the `pandoc.mediabag` modules are moved to a separate Haskell module. Change: minor
2017-12-21Lua modules: move to dedicated submoduleAlbert Krewinkel1-0/+213
The Haskell module defining the Lua `pandoc` module is moved to Text.Pandoc.Lua.Module.Pandoc. Change: minor
