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.

In the translation from String to Text, a char-width-sensitive
splitAt' was dropped. This commit reinstates it.
Closes #7214.

Instead of encoding a giant (and incomplete) map, we now
just use unicode-transforms to normalize the text to
a canonical decomposition, and manipulate the result.
The new `toAsciiText` is equivalent to the old
`T.pack . mapMaybe toAsciiChar . T.unpack` but should be faster.

[API change]
These are inefficient association list lookups.
Replace with more efficient functions in the writers that
used them (with 10-25% performance improvements in
haddock, org, rtf, texinfo writers).

T.P.Parsing: revise type of readWithM so that it takes a Text
rather than a polymorphic ToText value.
These typeclasses were there to ease the transition from String
to Text. They are no longer needed, and they may clash with
more useful versions under the same name.
This will require a bump to 2.13.

Rationale: the manual says that the XDG data directory will
be used if it exists, otherwise the legacy data directory.
So we should just determine this and use this directory,
rather than having a search path which could cause some
things to be taken from one data directory and others from
others.

Removed:
- `splitByIndices`
- `splitStringByIndicies`
- `substitute`
- `underlineSpan`
None of these are used elsewhere in the code base.

Cleanup up some functions and added deprecation pragmas
to funtions no longer used in the code base.

* 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.

...is present. Previously the attribute was included but given
an empty value, and this caused the table of contents creation
functions in T.P.Writers.Shared to think these items had numbers,
which meant that they were included in the TOC even if the `unlisted`
class was used.
Closes #6339.
|
|
Deprecate `underlineSpan` in Shared in favor of `Text.Pandoc.Builder.underline`.
|
|
|

Closes #6295.

- Writers.Native is now adapted to the new Table type.
- Inline captions should now be conditionally wrapped in a Plain, not
a Para block.
- The toLegacyTable function now lives in Writers.Shared.

* 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.

All warnings are either fixed or, if more appropriate, HLint is
configured to ignore them. HLint suggestions remain.

* 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 <$ 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

I'm not sure how this one slipped past me.
* Increase a bit of indentation

With positive heading shifts, starting in 2.8 this option caused
metadata titles to be removed and changed to regular headings.
This behavior is incompatible with the old behavior of
`--base-header-level` and breaks old workflows, so with this
commit we are rolling back this change.
Now, there is an asymmetry in positive and negative heading
level shifts:
+ With positive shifts, the metadata title stays the same and
does not get changed to a heading in the body.
+ With negative shifts, a heading can be converted into the
metadata title.
I think this is a desirable combination of features, despite
the asymmetry. One might, e.g., want to have a document
with level-1 section headigs, but render it to HTML with
level-2 headings, retaining the metadata title (which pandoc
will render as a level-1 heading with the default template).
Closes #5957.
Revises #5615.

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.

* Add HTML Reader support for `<dfn>`, parsing this as a Span with class `dfn`.
* Change `htmlSpanLikeElements` implementation to retain classes,
attributes and inline content.

When a div surrounds multiple sections at the same level,
or a section of highre level followed by one of lower level,
then we just leave it as a div and create a new div for the
section.
Closes #5846, closes #5761.

If a list has an empty item, this should not count against
its being a tight list.
Closes #5857.

Parse <mark> elements from HTML as HTML span like elements, with a
single class matching the tag name `mark`. Mark elements are rendered to
HTML using the native <mark> element.
Fixes https://github.com/jgm/pandoc/issues/5797.
|
|
* Text.Pandoc.Shared: export `htmlSpanLikeElements` [API change]
This commit also introduces a mapping of HTML span like elements that
are internally represented as a Span with a single class, but that are
converted back to the original element by the html writer. As of now,
only the kbd element is handled this way. Ideally these elements should
be handled as plain AST values, but since that would be a breaking
change with a large impact, we revert to this stop-gap solution.
Fixes https://github.com/jgm/pandoc/issues/5796.

Note that we also now use emoji names for emojis
when `ascii_identifiers` is enabled.

+ Use makeSection from T.P.Shared. This deals better with
embedded divs. (Closes #5761.)
+ Remove chapter-title class from chapter h1, for now.
(Reverts one change made earlier; we may revisit this
in light of #5749.)
+ Avoid issuing warning multiple times when title not set (see #5760).

Deprecate --base-heading-level.
The new option does everything the old one does, but also
allows negative shifts. It also promotes the document
metadata (if not null) to a level-1 heading with a +1 shift,
and demotes an initial level-1 heading to document metadata
with a -1 shift. This supports converting documents that
use an initial level-1 heading for the document title.
Closes #5615.

Text.Pandoc.Shared:
+ Remove `Element` type [API change]
+ Remove `makeHierarchicalize` [API change]
+ Add `makeSections` [API change]
+ Export `deLink` [API change]
Now that we have Divs, we can use them to represent the structure
of sections, and we don't need a special Element type.
`makeSections` reorganizes a block list, adding Divs with
class `section` around sections, and adding numbering
if needed.
This change also fixes some longstanding issues recognizing
section structure when the document contains Divs.
Closes #3057, see also #997.
All writers have been changed to use `makeSections`.
Note that in the process we have reverted the change
c1d058aeb1c6a331a2cc22786ffaab17f7118ccd
made in response to #5168, which I'm not completely
sure was a good idea.
Lua modules have also been adjusted accordingly.
Existing lua filters that use `hierarchicalize` will
need to be rewritten to use `make_sections`.

even if they're in divs. Improves #3057.
|
|
The structure
```
<h1>one</h1>
<div>
<h1>two</h1>
</div>
```
should create two coordinate sections, not a section with
a subsection. Now it does.
Extends #3057.
|
|
Previously Divs were opaque to hierarchicalize, so headings
inside divs didn't get into the table of contents, for
example (#3057).
Now hierarchicalize treats Divs as sections when appropriate.
For example, these structures both yield a section and a
subsection:
``` html
<div>
<h1>one</h1>
<div>
<h2>two</h2>
</div>
</div>
```
``` html
<div>
<h1>one</h1>
<div>
<h1>two</h1>
</div>
</div>
```
Note that
``` html
<h1>one</h1>
<div>
<h2>two</h2>
</div>
<h1>three</h1>
```
gets parsed as the structure
one
two
three
which may not always be desirable.
Closes #3057.

+ Remove Text.Pandoc.Pretty; use doclayout instead. [API change]
+ Text.Pandoc.Writers.Shared: remove metaToJSON, metaToJSON'
[API change].
+ Text.Pandoc.Writers.Shared: modify `addVariablesToContext`,
`defField`, `setField`, `getField`, `resetField` to work with
Context rather than JSON values. [API change]
+ Text.Pandoc.Writers.Shared: export new function `endsWithPlain` [API
change].
+ Use new templates and doclayout in writers.
+ Use Doc-based templates in all writers.
+ Adjust three tests for minor template rendering differences.
+ Added indentation to body in docbook4, docbook5 templates.
The main impact of this change is better reflowing of content
interpolated into templates. Previously, interpolated variables
were rendered independently and intepolated as strings, which could lead
to overly long lines. Now the templates interpolated as Doc values
which may include breaking spaces, and reflowing occurs
after template interpolation rather than before.

for non-ipynb formats, when the default "best" option is used with
--ipynb-output. The escape sequences cause problems in many formats,
including LaTeX. Closes #5633.

add `onlySimpleTableCells` to `Text.Pandoc.Shared`
[API change]
This fixes an inconsistency in the HTML reader, which did not treat tables with `<p>` inside cells as simple.

In the end we need a 1-1 map of mime types to output blocks.
