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.
2018-12-31Remove unused HasHeaderMap (#5175)Alexander1-16/+1
It is updated by some readers, but never actually used.
2018-12-17Parsing: use safeRead instead of read.John MacFarlane1-1/+1
2018-11-11Text.Pandoc.Shared: add parameter to uniqueIdent, inlineListToIdentifier.John MacFarlane1-1/+1
The parameter is Extensions. This allows these functions to be sensitive to the settings of `Ext_gfm_auto_identifiers` and `Ext_ascii_identifiers`. This allows us to use `uniqueIdent` in the CommonMark reader, replacing some custom code. It also means that `gfm_auto_identifiers` can now be used in all formats. Semantically, `gfm_auto_identifiers` is now a modifier of `auto_identifiers`; for identifiers to be set, `auto_identifiers` must be turned on, and then the type of identifier produced depends on `gfm_auto_identifiers` and `ascii_identifiers` are set. Closes #5057.

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.

2018-01-14Markdown reader: Improved inlinesInBalancedBrackets.John MacFarlane1-0/+1
The change both improves performance and fixes a regression whereby normal citations inside inline notes were not parsed correctly. Closes jgm/pandoc-citeproc#315.

2017-11-19Allow spaces after `\(` and before `\)` with `tex_math_single_backslash`.John MacFarlane1-2/+2
Previously `\( \frac{1}{a} < \frac{1}{b} \)` was not parsed as math in `markdown` or `html` `+tex_math_single_backslash`.
2017-11-14Text.Pandoc.Parsing.uri: allow `&` and `=` as word characters.John MacFarlane1-1/+1
This fixes a bug where pandoc would stop parsing a URI with an empty attribute: for example, `&a=&b=` wolud stop at `a`. (The uri parser tries to guess which punctuation characters are part of the URI and which might be punctuation after it.) Closes #4068.

+ Added Ext_fenced_divs to Extensions (default for pandoc Markdown). + Document fenced_divs extension in manual. + Implemented fenced code divs in Markdown reader. + Added test. Closes #168.
2017-08-28RST reader: handle blank lines correctly in line blocks (#3881)Alexander1-1/+1
Previously pandoc would sometimes combine two line blocks separated by blanks, and ignore trailing blank lines within the line block. Test is checked to be consisted with http://rst.ninjs.org/
2017-08-19Markdown reader: use CommonMark rules for list item nesting.John MacFarlane1-8/+28
Closes #3511. Previously pandoc used the four-space rule: continuation paragraphs, sublists, and other block level content had to be indented 4 spaces. Now the indentation required is determined by the first line of the list item: to be included in the list item, blocks must be indented to the level of the first non-space content after the list marker. Exception: if are 5 or more spaces after the list marker, then the content is interpreted as an indented code block, and continuation paragraphs must be indented two spaces beyond the end of the list marker. See the CommonMark spec for more details and examples. Documents that adhere to the four-space rule should, in most cases, be parsed the same way by the new rules. Here are some examples of texts that will be parsed differently: - a - b will be parsed as a list item with a sublist; under the four-space rule, it would be a list with two items. - a code Here we have an indented code block under the list item, even though it is only indented six spaces from the margin, because it is four spaces past the point where a continuation paragraph could begin. With the four-space rule, this would be a regular paragraph rather than a code block. - a code Here the code block will start with two spaces, whereas under the four-space rule, it would start with `code`. With the four-space rule, indented code under a list item always must be indented eight spaces from the margin, while the new rules require only that it be indented four spaces from the beginning of the first non-space text after the list marker (here, `a`). This change was motivated by a slew of bug reports from people who expected lists to work differently (#3125, #2367, #2575, #2210, #1990, #1137, #744, #172, #137, #128) and by the growing prevalance of CommonMark (now used by GitHub, for example). Users who want to use the old rules can select the `four_space_rule` extension. * Added `four_space_rule` extension. * Added `Ext_four_space_rule` to `Extensions`. * `Parsing` now exports `gobbleAtMostSpaces`, and the type of `gobbleSpaces` has been changed so that a `ReaderOptions` parameter is not needed.
2017-08-08Parsing: added gobbleSpaces.John MacFarlane1-0/+12
This is a utility function to use in list parsing.

2017-07-07Parsing: added takeP, takeWhileP for efficient parsing of [Char].John MacFarlane1-2/+33
2017-07-07Rewrote LaTeX reader with proper tokenization.John MacFarlane1-45/+22
This rewrite is primarily motivated by the need to get macros working properly. A side benefit is that the reader is significantly faster (27s -> 19s in one benchmark, and there is a lot of room for further optimization). We now tokenize the input text, then parse the token stream. Macros modify the token stream, so they should now be effective in any context, including math. Thus, we no longer need the clunky macro processing capacities of texmath. A custom state LaTeXState is used instead of ParserState. This, plus the tokenization, will require some rewriting of the exported functions rawLaTeXInline, inlineCommand, rawLaTeXBlock. * Added Text.Pandoc.Readers.LaTeX.Types (new exported module). Exports Macro, Tok, TokType, Line, Column. [API change] * Text.Pandoc.Parsing: adjusted type of `insertIncludedFile` so it can be used with token parser. * Removed old texmath macro stuff from Parsing. Use Macro from Text.Pandoc.Readers.LaTeX.Types instead. * Removed texmath macro material from Markdown reader. * Changed types for Text.Pandoc.Readers.LaTeX's rawLaTeXInline and rawLaTeXBlock. (Both now return a String, and they are polymorphic in state.) * Added orgMacros field to OrgState. [API change] * Removed readerApplyMacros from ReaderOptions. Now we just check the `latex_macros` reader extension. * Allow `\newcommand\foo{blah}` without braces. Fixes #1390. Fixes #2118. Fixes #3236. Fixes #3779. Fixes #934. Fixes #982.
2017-06-19Tracing: give less misleading line information with parseWithString.John MacFarlane1-1/+2
Previously positions would be reported past the end of the chunk. We now reset the source position within the chunk and report positions "in chunk."
2017-05-28Parsing: `many1Till`: Check for the end condition before parsingHerwig Stuetz1-2/+3
By not checking for the end condition before the first parse, the parser was applied too often, consuming too much of the input. This fixes the behaviour of `testStringWith (many1Till (oneOf "ab") (string "aa")) "aaa"` which before incorrectly returned `Right "a"`. With this change, it instead correctly fails with `Left (PandocParsecError ...)` because it is not able to parse at least one occurence of `oneOf "ab"` that is not `"aa"`. Note that this only affects `many1Till p end` where `p` matches on a prefix of `end`.
