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.
Instead of swallowing an empty line and then reintroducing it back again
in certain cases, collect the list item body in an unaltered form and
let the recursive parsing call sort things out.
Fixes issue #228.
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.
Replace output truncation with appropriate inline callbacks. lineBreak()
is now only responsible for handling HardLineBreak. BackslashLineBreak
is handled in escape() and trailing whitespace is considered in
maybeLineBreak().
Link parser used to truncate in two cases: when parsing image links and
inline footnotes. In order to avoid this truncation, introduce a
separate callback for each of these cases and avoid writing extra
characters instead of truncating them after the fact.
