The List module is automatically loaded, but not assigned to a global
variable. It can be included in filters by calling `List = require
'List'`.
Lists of blocks, lists of inlines, and lists of classes are now given
`List` as a metatable, making working with them more convenient. E.g.,
it is now possible to concatenate lists of inlines using Lua's
concatenation operator `..` (requires at least one of the operants to
have `List` as a metatable):
function Emph (emph)
local s = {pandoc.Space(), pandoc.Str 'emphasized'}
return pandoc.Span(emph.content .. s)
end
Closes: #4081
The `text` module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:
text = require 'text'
function Str (s)
s.text = text.upper(s.text)
return s
end
Refactored some code from Text.Pandoc.Lua.PandocModule
into new internal module Text.Pandoc.Lua.Filter.
Add `walk_inline` and `walk_block` in pandoc lua module.
The line identifiers are built using the code block's identifier
as a prefix. If the code block has null identifier, we use
"cb1", "cb2", etc.
Closes#4031.
This prevents the problem with extra space around highlighted
code blocks (closes#3996).
Note that we no longer put an enclosing div around highlighted
code blocks. The pre is the outer element, just as for unhighlighted
blocks.
Previously `\include` wouldn't work if the included file
contained, e.g., a begin without a matching end.
We've changed the Tok type so that it stores a full SourcePos,
rather than just a line and column. So tokens keeep track
of the file they came from. This allows us to use a simpler
method for includes, which doesn't require parsing the included
document as a whole.
Closes#3971.
Now all the guts of openURL have been put into openURL from
Class. openURL is now sensitive to stRequestHeaders in CommonState
and will add these custom headers when making a request.
It no longer looks at the USER_AGENT environment variable,
since you can now set the `User-Agent` header directly.
We now use the default.latex template for both latex and beamer.
It contains conditionals for the beamer-specific things.
`pandoc -D beamer` will return this template.
Stack instances for common data types are now provides by hslua. The
instance for Either was useful only for a very specific case; the
function that was using the `ToLuaStack Either` instance was rewritten
to work without it.
Closes: #3805
