2020-03-15Use implicit Prelude (#6187)Albert Krewinkel8-16/+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 * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary.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.

2020-03-13Lua marshalling: Remove unused language extensionsAlbert Krewinkel4-8/+3
2020-02-07Apply linter suggestions. Add fix_spacing to lint target in Makefile.John MacFarlane2-2/+0
2020-02-07Resolve HLint warningsAlbert Krewinkel1-1/+0
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 Krewinkel1-0/+45
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].despresc2-6/+9
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 MacFarlane1-0/+31
This will allow structured values. [API change]
2019-09-08Replace Element and makeHierarchical with makeSections.John MacFarlane1-31/+0
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`.
2019-06-12Lua: add a `clone()` method to all AST elements (#5572)Albert Krewinkel1-1/+4
Closes: #5568
2019-05-29pandoc.mediabag module: add items function iterating over mediabagAlbert Krewinkel1-0/+75
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 Version type: shorten "version too old" messageAlbert Krewinkel1-1/+1
2019-05-29Lua: add Version type to simplify comparisonsAlbert Krewinkel1-0/+154
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.
