2020-11-14Revise deprecation warning for --atx-headers.John MacFarlane1-1/+1
2020-11-14Markdown writer: default to using ATX headings.Aner Lucero1-1/+18
Previously we used Setext (underlined) headings by default. The default is now ATX (`##` style). * Add the `--markdown-headings=atx|setext` option. * Deprecate `--atx-headers`. * Add constructor 'ATXHeadingInLHS` constructor to `LogMessage` [API change]. * Support `markdown-headings` in defaults files. * Document new options in MANUAL. Closes #6662.
2020-10-19More refinements to --version output.John MacFarlane1-3/+4
Add ipynb version. Put user data directory on same line as heading "User data directory" (dropping "default").
2020-10-19Modify --version output.John MacFarlane1-8/+8
Use space more efficiently and report the citeproc version along with skylighting, texmath, and pandoc-types.
2020-10-04Sort languages in `--list-highlight-languages` output (#6718)Albert Krewinkel1-1/+1
Languages appear to be sorted by their long name, which leads to unexpected results: e.g., the long name of *m4* is *GNU m4*, so it is listed between *gnuassembler* and *go*.
2020-09-21Add built-in citation support using new citeproc library.John MacFarlane1-0/+6
This deprecates the use of the external pandoc-citeproc filter; citation processing is now built in to pandoc. * Add dependency on citeproc library. * Add Text.Pandoc.Citeproc module (and some associated unexported modules under Text.Pandoc.Citeproc). Exports `processCitations`. [API change] * Add data files needed for Text.Pandoc.Citeproc: default.csl in the data directory, and a citeproc directory that is just used at compile-time. Note that we've added file-embed as a mandatory rather than a conditional depedency, because of the biblatex localization files. We might eventually want to use readDataFile for this, but it would take some code reorganization. * Text.Pandoc.Loging: Add `CiteprocWarning` to `LogMessage` and use it in `processCitations`. [API change] * Add tests from the pandoc-citeproc package as command tests (including some tests pandoc-citeproc did not pass). * Remove instructions for building pandoc-citeproc from CI and release binary build instructions. We will no longer distribute pandoc-citeproc. * Markdown reader: tweak abbreviation support. Don't insert a nonbreaking space after a potential abbreviation if it comes right before a note or citation. This messes up several things, including citeproc's moving of note citations. * Add `csljson` as and input and output format. This allows pandoc to convert between `csljson` and other bibliography formats, and to generate formatted versions of CSL JSON bibliographies. * Add module Text.Pandoc.Writers.CslJson, exporting `writeCslJson`. [API change] * Add module Text.Pandoc.Readers.CslJson, exporting `readCslJson`. [API change] * Added `bibtex`, `biblatex` as input formats. This allows pandoc to convert between BibLaTeX and BibTeX and other bibliography formats, and to generated formatted versions of BibTeX/BibLaTeX bibliographies. * Add module Text.Pandoc.Readers.BibTeX, exporting `readBibTeX` and `readBibLaTeX`. [API change] * Make "standalone" implicit if output format is a bibliography format. This is needed because pandoc readers for bibliography formats put the bibliographic information in the `references` field of metadata; and unless standalone is specified, metadata gets ignored. (TODO: This needs improvement. We should trigger standalone for the reader when the input format is bibliographic, and for the writer when the output format is markdown.) * Carry over `citationNoteNum` to `citationNoteNumber`. This was just ignored in pandoc-citeproc. * Text.Pandoc.Filter: Add `CiteprocFilter` constructor to Filter. [API change] This runs the processCitations transformation. We need to treat it like a filter so it can be placed in the sequence of filter runs (after some, before others). In FromYAML, this is parsed from `citeproc` or `{type: citeproc}`, so this special filter may be specified either way in a defaults file (or by `citeproc: true`, though this gives no control of positioning relative to other filters). TODO: we need to add something to the manual section on defaults files for this. * Add deprecation warning if `upandoc-citeproc` filter is used. * Add `--citeproc/-C` option to trigger citation processing. This behaves like a filter and will be positioned relative to filters as they appear on the command line. * Rewrote the manual on citatations, adding a dedicated Citations section which also includes some information formerly found in the pandoc-citeproc man page. * Look for CSL styles in the `csl` subdirectory of the pandoc user data directory. This changes the old pandoc-citeproc behavior, which looked in `~/.csl`. Users can simply symlink `~/.csl` to the `csl` subdirectory of their pandoc user data directory if they want the old behavior. * Add support for CSL bibliography entry formatting to LaTeX, HTML, Ms writers. Added CSL-related CSS to styles.html.
2020-09-19Command line options: use normalizePath in more places.John MacFarlane1-14/+25
See #5127. It is now used everywhere a file argument can be used. Closes #5127.
2020-09-13Fix hlint suggestions, update hlint.yaml (#6680)Christian Despres1-4/+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.
2020-08-06Options: Add `/tex-mml-chtml.js` to defaultMathJaxURL.John MacFarlane1-2/+1
Previously we added this in processing command line options, but not in processing defaults files, which was inconsistent. Cloess #6593.
2020-04-17Revert 0e48a02 and dependency on base-noprelude...John MacFarlane1-2/+2
which hasn't been updated for ghc 8.10. See discussion at #6187.
2020-04-13Add an option to disable certificate validation (#6156)Cédric Couralet1-0/+5
This commit adds the option `--no-check-certificate`, which disables certificate checking when resources are fetched by HTTP. Co-authored-by: Cécile Chemin <cecile.chemin@insee.fr> Co-authored-by: Juliette Fourcot <juliette.fourcot@insee.fr>
2020-03-15Use implicit Prelude (#6187)Albert Krewinkel1-4/+2
* 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 Krewinkel1-2/+2
* Update copyright year * Copyright: add notes for Lua and Jira modules
2020-02-08Factor out a findM function (#6125)Joseph C. Sible1-10/+2
This adds a new function to the API: Text.Pandoc.Shared.findM.
2020-02-07Resolve HLint warningsAlbert Krewinkel1-5/+4
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 `$`s * Jira reader: remove unnecessary parentheses
2020-02-07More in-depth refactoring and cleanup (#6123)Joseph C. Sible1-8/+7
* Avoid duplicating the dash case * Pull common functions out of case branches * Make sure list lengths are only calculated once * Use unless * Simplify parseURIReference' and avoid an unnecessary call to length * Use <$> instead of reimplementing it * Use swap instead of reimplementing it * Remove eta-expansion that's been unnecessary since 90f5dd8 * Use tailDef instead of reimplementing it * Use second instead of fmap, per @tarleb
2020-01-31Support 'bibliography' and 'csl' fields in defaults file.John MacFarlane1-23/+1
Move addMeta from T.P.App.CommandLineOptions to T.P.App.Opt. (not an api change because modules not exported)
2020-01-08Change setVariable to use Text instead of String.John MacFarlane1-10/+10
This avoids some unnecessary unpacking. (This is only an internal module so it's not an API change.)
2019-12-26Use HTTPS in copyright message (#6010)Felix Yan1-1/+1
Since the website now redirect to https automatically, it would be nice to just use https in the help text.
2019-12-04Fix regression with behavior of --variable.John MacFarlane1-2/+8
Previously -Vfoo=1 -Vfoo=2 would produce a list value for foo; with 2.8 it produced just '2'. This commit restores the earlier beahvior. Closes #5962.
2019-11-26Add pdf to list of output formats (`--list-output-formats`).John MacFarlane1-1/+2
Closes #5938.
2019-11-17Reverted the behavior change with `--title-prefix`.John MacFarlane1-1/+2
It now implies `--standalone` again, as before.
2019-11-17Ensure that options imply `--standalone` even in defaults file.John MacFarlane1-14/+15
Certain options (`--self-contained`, `--include-in-header`, etc.) imply `--standalone`. We now handle this after option parsing so that it affects options specified in defaults files too. Behavior change: `--title-prefix` no longer implies `--standalone`.
2019-11-14Change optInputFiles to a `Maybe [FilePath]`.John MacFarlane1-1/+5
`Nothing` means: nothing specified. `Just []` means: an empty list specified (e.g. in defaults). Potentially these could lead to different behavior: see #5888.
2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-49/+52
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.
2019-11-07Fix list fields in Opt so they aren't reversed.John MacFarlane1-4/+4
Previously optIncludeInHeader, etc. were in reverse order. This has been changed to promote #5881. Note also that the `sourcefile` variable used to be sometimes a string, sometimes a list (when there was more than one). Now it is always a list.
2019-11-07Change merge behavior for metadata.John MacFarlane1-1/+1
Previously, if a document contained two YAML metadata blocks that set the same field, the conflict would be resolved in favor of the first. Now it is resolved in favor of the second (due to a change in pandoc-types). This makes the behavior more uniform with other things in pandoc (such as reference links and `--metadata-file`).
2019-11-06Add and apply filters in order (not reversed).John MacFarlane1-4/+2
This changes `applyFilters` from Text.Pandoc.Filter so that it does a left fold rather than a right fold, applying the filters in the order listed. [behavior change] The command-line arguments are accumulated in order instead of reverse order. A first step twoards #5881.
2019-11-02Move extension-adding to applyDefaultsJohn MacFarlane1-6/+5
2019-11-01Revert "ALlow multiple comma-separated files for `--defaults`."John MacFarlane1-7/+6
This reverts commit e96f3fd813b3f8b73c3457ff6e9177e2a4a74164.
2019-11-01ALlow multiple comma-separated files for `--defaults`.John MacFarlane1-6/+7
2019-11-01Factor out applyDefaults in T.P.A.CommandLineOptions.John MacFarlane1-20/+24
2019-11-01`--defaults` improvements.John MacFarlane1-1/+1
- ToYAML instance is now for `Opt -> Opt`, rather than `Opt`. - This allows us to handle `--defaults` without clobbering all the options that occur prior to `--defaults` on the command line. (Note, however, that options in `--defaults` can replace these options if the `--defaults` option is used after them, which may be a bit confusing given the name.) - `--defaults` may now be used multiple times on the command line, allowing users to break defaults into different chunks.
2019-10-11Remove redundant import.John MacFarlane1-1/+0
2019-10-10Improve parsing of --defaults.John MacFarlane1-19/+19
- Add FromYAML instances to Opt and to all subsidiary types. - Remove the use of HsYAML-aeson, which doesn't give good position information on errors. - Rename some fields in Opt to better match cli options or reflect what the ycontain [API change]: + optMetadataFile -> optMetadataFiles + optPDFEngineArgs -> optPDFEngineOpts + optWrapText -> optWrap - Add IpynbOutput enumerated type to Text.Pandoc.App.Opts. Use this instead fo a string for optIpynbOutput. - Add FromYAML instance for Filter in Text.Pandoc.Filters. With these changes parsing of defaults files should be complete and should give decent error messages. Now (unlike before) we get an error if an unknown field is used.
2019-10-10Add -d as synonym for --defaults.John MacFarlane1-1/+1
2019-10-10Reorder options in `--help`.John MacFarlane1-58/+58
2019-10-10`--metadata-file`: when multiple files specified, second takes precedence...John MacFarlane1-1/+1
on conflicting fields. This changes earlier behavior (but not in a release), where first took precedence. Note that this may seem inconsistent with the behavior of multiple YAML blocks within a document, where the first takes precedence. Still, it is convenient to be able to override defaults with options later on the command line.
2019-10-10Remove unnecessary import.John MacFarlane1-1/+0
2019-10-09--defaults: add .yaml extension if absent, look in user data dir...John MacFarlane1-13/+30
under "defaults" subdirectory.
2019-10-09T.P.App.Opt: rename optReader, optWriter as optFrom, optTo.John MacFarlane1-2/+2
This will allow to: and from: in defaults.
2019-10-09Make sure that input-files works in --default files.John MacFarlane1-1/+1
2019-10-09Basic changes for MathJax 3.zorkow1-1/+1
2019-10-09Initial implementation of --defaults option.John MacFarlane1-2/+23
Need documentation.
2019-10-09T.P.App.Opt: Changed optMetadata to Meta, to allow structured values.John MacFarlane1-4/+28
[API change] The current behavior of the `--metadata` option stays the same.
2019-10-09Change optVariables from [(String, String)] to Context Text.John MacFarlane1-6/+17
In Text.Pandoc.App.Opt [API change].
2019-10-07Remove derive_json_via_th flag; always use TH.John MacFarlane1-3/+0
This cuts down on code duplication and reduces the chance for errors. See #4083.
2019-10-07Remove redundant import.John MacFarlane1-1/+0
2019-10-06Opt: Change optHighlightStyle to a Maybe String instead of Maybe Style.John MacFarlane1-19/+21
Do the parsing/loading of themes later, after option parsing.
