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.
A default HTML renderer for a single node is now easily accessible.
Makes it easy to fall back to the default behavior when writing custom
HTML renderers.
This commit does some changes to the test suite. The changes are only to
the newlines. Turns out the former implementation of footnotes produced
slightly different spacing when rendering the footnotes list. The new
implementation produces the list that is compatible with the rest of the
package.
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.
This is the new renderer that walks AST and renders everything to a
buffer. Completely covers all the functionality of the previous renderer
and will likely replace it.
Remove the 'out' parameter. Also, instead of returning and passing the
position of TOC, use CopyWrites to capture contents of the header and
pass that captured buffer instead.
Add a structure to collect output in a buffer (replaces what used to be
the 'out' parameter all over the place).
Notable things about this struct are the captureBuff and copyBuff
buffers. They're intended to redirect all the output (captureBuff) or
make a copy of all the output (copyBuff) while they're set to non-nil.
Here's an example of their intended use:
// what used to be a temp buffer as an 'out' parameter
// var cellWork bytes.Buffer
// p.inline(&cellWork, data[cellStart:cellEnd])
// can now be captured like this:
cellWork := p.r.CaptureWrites(func() {
p.inline(data[cellStart:cellEnd])
})
Change the way maybeLineBreak gets called to avoid breaking up stretches
of unprocessed characters that smartypants expects.
This inline processing is getting a bit out of hand, something needs to
be done about it.
Autolink detection used to be triggered by a colon and preceding
protocol name used to be rewound. Now instead of doing that, trigger
autolink processing on [hmfHMF] and see if it looks like a link.
