2021-02-18DocBook, JATS, OPML readers: performance optimization.John MacFarlane1-21/+1
With the new XML parser, we can avoid the expensive tree normalization step we used to do. This gives a significant speed boost in docbook and JATS parsing (e.g. 9.7 to 6 ms).
2021-02-16Rename Text.Pandoc.XMLParser -> Text.Pandoc.XML.Light...John MacFarlane1-17/+12
..and add new definitions isomorphic to xml-light's, but with Text instead of String. This allows us to keep most of the code in existing readers that use xml-light, but avoid lots of unnecessary allocation. We also add versions of the functions from xml-light's Text.XML.Light.Output and Text.XML.Light.Proc that operate on our modified XML types, and functions that convert xml-light types to our types (since some of our dependencies, like texmath, use xml-light). Update golden tests for docx and pptx. OOXML test: Use `showContent` instead of `ppContent` in `displayDiff`. Docx: Do a manual traversal to unwrap sdt and smartTag. This is faster, and needed to pass the tests. Benchmarks: A = prior to 8ca191604dcd13af27c11d2da225da646ebce6fc (Feb 8) B = as of 8ca191604dcd13af27c11d2da225da646ebce6fc (Feb 8) C = this commit | Reader | A | B | C | | ------- | ----- | ------ | ----- | | docbook | 18 ms | 12 ms | 10 ms | | opml | 65 ms | 62 ms | 35 ms | | jats | 15 ms | 11 ms | 9 ms | | docx | 72 ms | 69 ms | 44 ms | | odt | 78 ms | 41 ms | 28 ms | | epub | 64 ms | 61 ms | 56 ms | | fb2 | 14 ms | 5 ms | 4 ms |
2021-02-10Add new unexported module T.P.XMLParser.John MacFarlane1-2/+8
This exports functions that uses xml-conduit's parser to produce an xml-light Element or [Content]. This allows existing pandoc code to use a better parser without much modification. The new parser is used in all places where xml-light's parser was previously used. Benchmarks show a significant performance improvement in parsing XML-based formats (especially ODT and FB2). Note that the xml-light types use String, so the conversion from xml-conduit types involves a lot of extra allocation. It would be desirable to avoid that in the future by gradually switching to using xml-conduit directly. This can be done module by module. The new parser also reports errors, which we report when possible. A new constructor PandocXMLError has been added to PandocError in T.P.Error [API change]. Closes #7091, which was the main stimulus. These changes revealed the need for some changes in the tests. The docbook-reader.docbook test lacked definitions for the entities it used; these have been added. And the docx golden tests have been updated, because the new parser does not preserve the order of attributes. Add entity defs to docbook-reader.docbook. Update golden tests for docx.
2021-01-08Update copyright notices for 2021 (#7012)Albert Krewinkel1-1/+1
2020-03-22Finer grained imports of Text.Pandoc.Class submodules (#6203)Albert Krewinkel1-1/+1
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 Krewinkel1-2/+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.

2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-12/+17
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.
2019-03-01Remove license boilerplate.John MacFarlane1-18/+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.
2019-02-04Add missing copyright notices and remove license boilerplate (#5112)Albert Krewinkel1-2/+2
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.
2018-04-25Added licensing headers for DocBook, EPUB, JATS, OPML readers.John MacFarlane1-0/+30
See #4592.
2018-03-29Removed unused extensions (#4506)Anabra1-1/+0
2018-03-18Use NoImplicitPrelude and explicitly import Prelude.John MacFarlane1-0/+2
This seems to be necessary if we are to use our custom Prelude with ghci. Closes #4464.
2017-12-22API change: export blocksToInlines' from Text.Pandoc.Sharedmb211-2/+2
2017-12-17OPML reader: enable raw HTML and other extensions by default for notes.John MacFarlane1-9/+14
This fixes a regression in 2.0. Note that extensions can now be individually disabled, e.g. `-f opml-smart-raw_html`. Closes #4164.
2017-10-29More hlint fixes.John MacFarlane1-1/+1
2017-10-27hlint suggestions.John MacFarlane1-8/+7
2017-10-27Automatic reformating by stylish-haskell.John MacFarlane1-2/+2
2017-06-20Move CR filtering from tabFilter to the readers.John MacFarlane1-1/+3
The readers previously assumed that CRs had been filtered from the input. Now we strip the CRs in the readers themselves, before parsing. (The point of this is just to simplify the parsers.) Shared now exports a new function `crFilter`. [API change] And `tabFilter` no longer filters CRs.
2017-06-17Use Control.Monad.State.Strict throughout.John MacFarlane1-1/+1
This gives 20-30% speedup and reduction of memory usage in most of the writers.
2017-06-10Changed all readers to take Text instead of String.John MacFarlane1-4/+6
Readers: Renamed StringReader -> TextReader. Updated tests. API change.

2016-09-02Remove TagSoup compatJesse Rosenthal1-2/+2
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.
2016-09-02Remove Text.Pandoc.Compat.ExceptJesse Rosenthal1-1/+1
2015-11-09Revert "Use -XNoImplicitPrelude and 'import Prelude' explicitly."John MacFarlane1-1/+0
This reverts commit c423dbb5a34c2d1195020e0f0ca3aae883d0749b.
2015-11-08Use -XNoImplicitPrelude and 'import Prelude' explicitly.John MacFarlane1-0/+1
This is needed for ghci to work with pandoc, given that we now use a custom prelude. Closes #2503.
2015-10-14Use custom Prelude to avoid compiler warnings.John MacFarlane1-2/+0
- The (non-exported) prelude is in prelude/Prelude.hs. - It exports Monoid and Applicative, like base 4.8 prelude, but works with older base versions. - It exports (<>) for mappend. - It hides 'catch' on older base versions. This allows us to remove many imports of Data.Monoid and Control.Applicative, and remove Text.Pandoc.Compat.Monoid. It should allow us to use -Wall again for ghc 7.10.
2015-02-18Change return type of OPML readerMatthew Pickering1-20/+28
2013-08-08Added Text.Pandoc.Compat.TagSoupEntity.John MacFarlane1-1/+1
This allows pandoc to compile with tagsoup 0.13.x. Thanks to Dirk Ullrich for the patch.
2013-03-20OPML reader: Type attributes are not case sensitive.John MacFarlane1-2/+2
So, `type="link"` or `type="LINK"`.
2013-03-19Added Text.Pandoc.Readers.OPML, exporting readOPML.John MacFarlane1-0/+95
The _note attribute is supported. This is unofficial, but used e.g. in OmniOutliner and supported by multimarkdown. We treat the contents as markdown blocks under a section header. Added to documentation and tests.
