2020-02-07Resolve HLint warningsAlbert Krewinkel42-177/+156
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 `$`s * Jira reader: remove unnecessary parentheses
2020-02-07More in-depth refactoring and cleanup (#6123)Joseph C. Sible8-44/+40
* Avoid duplicating the dash case * Pull common functions out of case branches * Make sure list lengths are only calculated once * Use unless * Simplify parseURIReference' and avoid an unnecessary call to length * Use <$> 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
2020-02-07Various minor cleanups and refactoring (#6117)Joseph C. Sible15-63/+56
* Use concatMap instead of reimplementing it * Replace an unnecessary multi-way if with a regular if * Use sortOn instead of sortBy and comparing * Use guards instead of lots of indents for if and else * Remove redundant do blocks * Extract common functions from both branches of maybe Whenever both the Nothing and the Just branch of maybe do the same function, do that function on the result of maybe instead. * Use fmap instead of reimplementing it from maybe * Use negative forms instead of negating the positive forms * Use mapMaybe instead of mapping and then using catMaybes * Use zipWith instead of mapping over the result of zip * Use unwords instead of reimplementing it * Use <$ instead of <$> and const * Replace case of Bool with if and else * Use find instead of listToMaybe and filter * Use zipWithM instead of mapM and zip * Inline lambda wrappers into the real functions * We get zipWithM from Text.Pandoc.Writers.Shared * Use maybe instead of fromMaybe and fmap I'm not sure how this one slipped past me. * Increase a bit of indentation
2020-02-06Use traverse instead of reimplementing it (#6124)Joseph C. Sible2-8/+3
2020-02-05Simplify an overcomplicated filtering function (#6115)Joseph C. Sible1-1/+1
There's no need to use `catMaybes`, `uncurry`, `bool`, etc., just to get elements where the second element of a tuple is True.
2020-02-05Fix --number-offset with HTML TOC.John MacFarlane1-10/+19
Eventually it would be worth adding a parameter to makeSections so this could be done at that level; then it would also affect other writers that construct TOC manually.
2020-02-05MediaWiki writer: prevent triple `[[[`.John MacFarlane1-1/+11
This confuses mediawiki's parser. So we insert a `<nowiki/>` no-op between a literal `[` and a link. Closes #6119.
2020-02-05LaTeX reader: skip comments in more places where this is needed.John MacFarlane2-19/+21
Closes #6114.
2020-02-04Remove our bool function (#6116)Joseph C. Sible2-9/+1
Data.Bool already provides a bool function identical to this one.
2020-02-04Add timing info for filters in `--verbose` mode.John MacFarlane2-5/+30
+ Add RunningFilter, FilterCompleted constructors to LogMessage + When verbose mode is specified (verbosity == INFO), print a notice when running a filter and when a filter completes (including timing). Closes #6112.
2020-02-03Allow & in LaTeX citation keys.John MacFarlane1-1/+1
Closes #6110.
2020-02-03Swap suboptimal uses of maybe and fromMaybe (#6111)Joseph C. Sible5-13/+13
Anywhere "maybe" is used with "id" as its second argument, using "fromMaybe" instead will simplify the code. Conversely, anywhere "fromMaybe" is used with the result of "fmap" or "<$>" as its second argument, using "maybe" instead will simplify the code.
2020-02-03Fix duplicate frame classes in LaTeX/Beamer output.John MacFarlane1-2/+2
Close #6107.
2020-02-03Clean up overcomplicated maybe logic (#6105)Joseph C. Sible1-8/+6
We're using maybe in redundant ways. Remove it altogether in one case and simplify it to fromMaybe in another.
2020-02-03Clean up a confusing triple negative (#6102)Joseph C. Sible1-5/+5
There's currently `unless`, `not`, and `notParaOrPlain` in the same expression, which is a rather confusing triple negative. Replace `notParaOrPlain` with `paraOrPlain` and switch to `all` from `any` to clean this up.
2020-02-01Text.Pandoc.Readers.CSV - reuse CSV parser from Text.Pandoc.CSV.John MacFarlane1-65/+5
2020-02-01Fix bug in Text.Pandoc.CSV.John MacFarlane1-4/+4
Previously an extra blank record would sometimes be inserted at the end.
2020-01-31Support 'bibliography' and 'csl' fields in defaults file.John MacFarlane2-24/+42
Move addMeta from T.P.App.CommandLineOptions to T.P.App.Opt. (not an api change because modules not exported)
2020-01-31csv reader: allow empty cells.John MacFarlane1-7/+5
2020-01-31Add Text.Pandoc.Readers.CSV (readCSV).John MacFarlane3-0/+112
This adds csv as an input format. The CSV table is converted into a pandoc simple table. Closes #6100.
2020-01-28Added a try that was needed for the commit fc78be1.John MacFarlane1-1/+1
The intent of that commit was to parse unknown LaTeX enivronments as verbatim if they can't be parsed normally, avoiding crashes on environments that allow unescaped underscores and the like. But the fix didn't completely work: it worked for raw TeX in markdown but not when reading LaTeX. This change fixes that. See #6034. Closes #6093.
2020-01-19Docx writer: fix regression with Compact style on tight lists. (#6073)John MacFarlane1-1/+9
Starting in 2.8, the docx writer no longer distinguishes between tight and loose lists, since the Compact style is omitted. This is a side-effect of the fix to #5670, as explained in the changelog: + Preserve built-in styles in DOCX with custom style (Ben Steinberg, #5670). This change prevents custom styles on divs and spans from overriding styles on certain elements inside them, like headings, blockquotes, and links. On those elements, the "native" style is required for the element to display correctly. This change also allows nesting of custom styles; in order to do so, it removes the default "Compact" style applied to Plain blocks, except when inside a table. This patch fixes the problem by extending the exception currently offered to Plain blocks inside tables to Plain blocks inside list items. Closes #6072.
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
2020-01-12HTML writer: fix duplicate attributes on headings.John MacFarlane1-9/+10
Another regression from 2.7.x. Closes #6062.
2020-01-10LaTeX reader: allow beamer overlays for all commands in all raw tex.John MacFarlane1-10/+10
This affecs parsing of raw tex in LaTeX and in Markdown and other formats. Closes #6043.
2020-01-08Change setVariable to use Text instead of String.John MacFarlane2-21/+20
This avoids some unnecessary unpacking. (This is only an internal module so it's not an API change.)
2020-01-08LaTeX reader: improve parsing of raw environments.John MacFarlane1-1/+1
If parsing fails in a raw environment (e.g. due to special characters like unescaped `_`), try again as a verbatim environment, which is less sensitive to special characters. This allows us to capture special environments that change catcodes as raw tex when `-f latex+raw_tex` is used. Closes #6034.
2020-01-07Jira writer: fix output of table headersAlbert Krewinkel1-4/+4
Headers were missing from tables. Fixes: #6035
2020-01-07Fix regression in handling of columns in beamer slides.John MacFarlane1-5/+6
Columns in title slides were causing problems with slide division. Closes #6033.
2020-01-07Reveal.js writer: restore old behavior for 2D nesting.John MacFarlane1-11/+17
The fix to #6030 actually changed behavior, so that the 2D nesting occurred at slide level N-1 and N, instead of at the top-level section. This commit restores the 2.7.3 behavior. If there are more than 2 levels, the top level is horizontal and the rest are collapsed to vertical. Closes #6032.
2020-01-05Fix regression in beamer slide structure with certain slide levels.John MacFarlane1-8/+17
Closes #6030.
2020-01-05Fix revealjs slide structure regression with certain slide levels.John MacFarlane1-6/+8
Partially addresses #6030.
2020-01-04Added a needed pragma.John MacFarlane1-0/+1
2020-01-04Add type annotations to assist ghci.John MacFarlane4-7/+13
2020-01-04Remove unneeded import.John MacFarlane1-1/+1
2020-01-04HTML writer: Add newlines to make slide show output more readable.John MacFarlane1-6/+8
2020-01-03PDF: fix runTeXProgram so that the input source is always overwritten.John MacFarlane1-22/+23
Previously it wasn't overridden if the file already existed, which led to bad results on subsequent runs when `pdf-engine-opt=-output-directory=` was used to specify an explicit temp dir. Closes #6027.
2020-01-03Org writer: remove extra spaces from table cellsAlbert Krewinkel1-1/+1
Closes: #6024
2020-01-01LaTeX writer: properly handle unnumbered headings level 4+.John MacFarlane1-1/+1
Closes #6018. Previously the `\paragraph` command was used instead of `\paragraph*` for unnumbered level 4 headings.
2019-12-30BCP47: change getLang so it can handle block-level contents.John MacFarlane1-3/+5
Some readers (e.g. RST) will populate the `lang` metadata field with block-level content. `getLang` has been modified to handle this. Previously in these cases the LaTeX writer would not properly set the "main language" of the document. Closes #6008.
2019-12-27Fix parsing bug affected indented code after raw HTML.John MacFarlane1-8/+10
Closes #6009, #5360.
2019-12-27Add a needed try.John MacFarlane1-2/+3
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.
2019-12-22Ensure that later default file values for `variable` replace earlier ones.John MacFarlane1-1/+3
The semigroup instance for doctemplates Context does a left-biased union on the underlying Map. That means that if you union `{a: 1}` and `{a: 2}`, you get `{a: 1}`. This commit causes pandoc to do the operation in the opposite order, so that later default files take precedence in the values they assign to keys. See #5988.
2019-12-21HTML writer: more tweaks to avoid round-trip failures...John MacFarlane1-2/+5
having to do with makeSections.
2019-12-21Fix regression with --number-sections.John MacFarlane1-2/+1
Starting with 2.8, `--number-sections` also had the effect of `--section-divs`, even if `--section-divs` was not specified.
2019-12-20Added glsl mime type for WebGL maps (#6000)Jared Lander1-0/+1
Added glsl mime type for WebGL maps
2019-12-20Jira writer: use jira-wiki-markup rendererAlbert Krewinkel1-266/+222
Pandoc's AST is translated into the Jira AST, which is then rendered by the dedicated Jira printer. The following improvements are included in this change: - non-jira raw blocks are fully discarded instead of showing as blank lines; - table cells can contain multiple blocks; - unnecessary blank lines are removed from the output; - markup chars within words are properly surrounded by braces; - preserving soft linebreaks via `--wrap=preserve` is supported. Note that backslashes are rendered as HTML entities, as there appears no alternative to produce a plain backslash if it is followed by markup. This may cause problems when used with confluence, where rendering seems to fail in this case. Closes: #5926
2019-12-19Org reader: report errors properlyAlbert Krewinkel1-2/+1
Errors during parsing are now returned in full and no longer replaced by a custom message.
2019-12-19Org reader: fix parsing problem for colons in headlineAlbert Krewinkel2-11/+27
Fixed a problem where words surrounded by colons could causing parse failures in some cases when they occurred in headers. Fixes: #5993
