* Text.Pandoc.Templates [API change]
+ Add Monad wrappers `WithDefaultPartials` and `WithPartials`.
Wrapping these around an instance of `PandocMonad` gives
us different instances of `TemplateMonad`, with different
search behavior in retrieving partials.
To compile a template and limit partial search to pandoc's
data files, use `runWithDefaultPartials (compileTemplate ...)`.
To compile a template and allow partials to be found locally
(either on the file system or via HTTP, in the event that
the main template has an absolute URL), ue
`runWithPartials (compileTemplate ...)`.
+ Export `getTemplate`, which seeks a template locally,
or via HTTP if the template has an absolute URL, falling
back to the data files if not found.
+ Export `compileDefaultTemplate` -- does `getDefaultTemplate`
and compiles the result, raising an error on failure.
* Text.Pandoc.Class [API change]
+ Remove `TemplateMonad` instances for `PandocIO` and `PandocPure`.
These were too limiting and caused a bug whereby a local
partial could be used even when the default template was requested.
We now rely on instances provided in the Templates module.
Text.Pandoc.App.OutputSettings
+ Simplify template retrieval code.
Added `\setupinterlinespace` to `title`, `subtitle`, `date` and `author` elements.
Otherwise longer titles that run over multiple lines will look squashed as
`\tfd` etc. won't adapt the line spacing to the font size.
Previously hierarchicalize (the ancestor of `makeSections`)
would put header attributes on the containing Div. In 2.8
this behavior changed, which broke some tools depending
on pandoc. Here we roll back this change, so that attributes
again migrate from the header to the containing Div when
`makeSections` is run. Note that attributes are retained
on the header as well (unlike before) -- with the exception
of the `id` attribute, which of course cannot be duplicated.
Note that this is an empty commit. The previous
commit, 8d0033111, was mistakenly recorded as an
amendment to the --toc-depth fix, so the commit message
for that is wrong; this message correctly describes
the change in 8d0033111.
Closes#5965.
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.
