2021-05-09Change reader types, allowing better tracking of source positions.John MacFarlane1-18/+16
Previously, when multiple file arguments were provided, pandoc simply concatenated them and passed the contents to the readers, which took a Text argument. As a result, the readers had no way of knowing which file was the source of any particular bit of text. This meant that we couldn't report accurate source positions on errors or include accurate source positions as attributes in the AST. More seriously, it meant that we couldn't resolve resource paths relative to the files containing them (see e.g. #5501, #6632, #6384, #3752). Add Text.Pandoc.Sources (exported module), with a `Sources` type and a `ToSources` class. A `Sources` wraps a list of `(SourcePos, Text)` pairs. [API change] A parsec `Stream` instance is provided for `Sources`. The module also exports versions of parsec's `satisfy` and other Char parsers that track source positions accurately from a `Sources` stream (or any instance of the new `UpdateSourcePos` class). Text.Pandoc.Parsing now exports these modified Char parsers instead of the ones parsec provides. Modified parsers to use a `Sources` as stream [API change]. The readers that previously took a `Text` argument have been modified to take any instance of `ToSources`. So, they may still be used with a `Text`, but they can also be used with a `Sources` object. In Text.Pandoc.Error, modified the constructor PandocParsecError to take a `Sources` rather than a `Text` as first argument, so parse error locations can be accurately reported. T.P.Error: showPos, do not print "-" as source name.
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 Krewinkel1-1/+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 * PandocMonad: remove outdated check for base version Only base versions 4.9 and later are supported, the check for `MIN_VERSION_base(4,8,0)` is therefore unnecessary.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.
2020-03-13Update copyright year (#6186)Albert Krewinkel1-1/+1
* Update copyright year * Copyright: add notes for Lua and Jira modules
2020-03-05Fix parsing of `\'` in man/ms readers.John MacFarlane1-1/+1
It was being parsed as a backtick. Closes #6175.
2020-03-05Fix parsing of `\.` in man/ms readers.John MacFarlane1-1/+1
Previously due to a typo it was being parsed as `` ` ``. Closes #6175.
2019-11-12Switch to new pandoc-types and use Text instead of String [API change].despresc1-93/+92
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.

2019-09-04Roff readers: better parsing of groups.John MacFarlane1-9/+5
We now allow groups where the closing `\\}` isn't at the beginning of a line. Closes #5410.
2019-03-01Remove license boilerplate.John MacFarlane1-20/+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.
