The root problem this commit fixes is the duplication of Extensions
field in HTMLRendererParameters. The duplication crept in there only to
support these two flags, so moving the flags solves the problem. They're
only used in renderer anyway.
Fixes#277.
Some renderers might not care to have an explicit list of footnotes at
the end of the document, instead they're interested in the content of
the footnote at the location of a referer. Make their lives easier by
providing such a link
Clean up footnotes part of an AST: don't force HTML-specific pieces
there, just keep a clean list of footnotes. Since some renderers might
want to process footnotes differently, let them know about footnotes by
having a flag on that list.
Move reference and footnote extraction code from firstPass to a
paragraph block parser. This makes firstPass a little bit slimmer, ergo
closer to elimination.
When parseRefsToAST constructs a list of footnotes, it hardcoded the
item flags to ListTypeOrdered and omitted ListItemBeginningOfList.
However, a quick look around indicates that ListItemBeginningOfList
might have lost its meaning altogether in v2 (it used to control item
spacing in v1, which is now extracted from the AST structure). So add a
TODO to clean that up one day.
Most of its body was redundant, as it was moved to parseRefsToAST. After
removal of that code, only a single line remains, so move it out to the
caller of secondPass.
* Only split when inline callbacks consume some bytes
The former hacks around maybeLineBreak and Smartypants are no longer
needed.
The algorithm has been streamlined: shorter, simpler, faster.
The 'currBlock' field of the parser is gone.
* Remove spurious logs
* Unpublish and rename LinkType constants
The constants are only used in the parsing phase, they are not recorded
in the AST directly, so make them private. Improve their names along the
way. Fix tagLength to return two values instead of taking an output
parameter.
* autoLinkType -> autolinkType
And remove unnecessary comment.
Move these two flags from HTML renderer's flags to extensions. Implement
both since they were not yet implemented in the AST rewrite. Add tests.
Note: the expected test strings differ very slightly from v1. The HTML
produced by v2 has a few extra newlines compared to the old one, but
it's now uniform with other sections of the generated document. If the
newline placement gets cleaned up in the future, this will get fixed
automatically, since the renderer is agnostic about the TOC list.
Separate Smartypants somewhat from the HTML renderer. Move its flags
from HtmlFlags to Extensions (probably should be moved to its own set of
flags, but not now). With that done, do a separate walk of the tree and
either run Smartypants processor if it's enabled, or simply escape text
nodes.
Build a partial tree by adding block nodes. The block nodes will then be
traversed and inline markdown parsed inside each of them. Tests are
broken at this point until the full tree is constructed.
