The implicitly defined global filter (i.e. all element filtering
functions defined in the global lua environment) is used if no filter is
returned from a lua script. This allows to just write top-level
functions in order to define a lua filter. E.g
function Emph(elem) return pandoc.Strong(elem.content) end
Attributes was written to behave much like a normal table, in order to
simplify working with it. However, all Attr containing elements were
changed to provide panflute-like accessors to Attr components, rendering
the previous approach unnecessary.
The `F` monads used for delayed evaluation of certain values in the
Markdown and Org readers are based on a shared data type capturing the
common pattern of both `F` types.
Previously the LaTeX writer created invalid LaTeX
when `--listings` was specified and a code span occured
inside emphasis or another construction.
This is because the characters `%{}\` must be escaped
in lstinline when the listinline occurs in another
command, otherwise they must not be escaped.
To deal with this, adoping Michael Kofler's suggestion,
we always wrap lstinline in a dummy command `\passthrough`,
now defined in the default template if `--listings` is
specified. This way we can consistently escape the
special characters.
Closes#1629.
A single `read` function parsing pandoc-supported formats is added to
the module. This is simpler and more convenient than the previous method
of exposing all reader functions individually.
Writer helper functions were defined in the top-level Text.Pandoc
module. These functions are moved to the Writer submodule as to enable
reuse in other submodules.
Reader helper functions were defined in the top-level Text.Pandoc
module. These functions are moved to the Readers submodule as to enable
reuse in other submodules.
Extension parsing and processing functions were defined in the top-level
Text.Pandoc module. These functions are moved to the Extensions
submodule as to enable reuse in other submodules.
Meta elements that are treated as lua tables (i.e. MetaList,
MetaInlines, MetaBlocks, and MetaMap), are no longer wrapped in an
additional table but simply marked via a metatable. This allows
treating those meta values just like normal tables, while still making
empty elements of those values distinguishable.
We now issue `<div class="line-block">` and include a
default definition for `line-block` in the default
templates, instead of hard-coding a `style` on the
div.
Closes#1623.
A figure with two subfigures turns into two pandoc
figures; the subcaptions are used and the main caption
ignored, unless there are no subcaptions.
Closes#3577.
Source block parameter names are no longer prefixed with *rundoc*. This
was intended to simplify working with the rundoc project, a babel
runner. However, the rundoc project is unmaintained, and adding those
markers is not the reader's job anyway.
The original language that is specified for a source element is now
retained as the `data-org-language` attribute and only added if it
differs from the translated language.
The line-numbering switch that can be given to source blocks (`-n` with
an start number as an optional parameter) is parsed and translated to a
class/key-value combination used by highlighting and other readers and
writers.
Previously we always added an empty div before the list
item, but this created problems with spacing in tight
lists. Now we do this:
If the list item contents begin with a Plain block,
we modify the Plain block by adding a Span around
its contents.
Otherwise, we add a Div around the contents of the
list item (instead of adding an empty Div to the
beginning, as before).
Closes#3596.
Element attributes are pushed to the stack via the `Attributes`
function. `Attributes` creates an Attr like triple, but the triple also
allows table-like access to key-value pairs.
Lua string are used to represent nullary data constructors. The previous
table-based representation was based on the JSON serialization, but can
be simplified. This also matches the way those arguments are passed to
custom writers.
The lua filters and custom lua writer system defined very similar
StackValue instances for strings and tuples. These instance definitions
are extracted to a separate module to enable sharing.
