The goal of this change is to reduce number of non-standard library
packages (repositories) that blackfriday imports (not counting imports
used only for tests) from 1 to 0, and in turn, reduce the cost of
importing blackfriday into other projects.
Do so by documenting the algorithm of SanitizedAnchorName, and include
a copy of the small function inside blackfriday itself. The same
functionality continues to be available in the original location,
github.com/shurcooL/sanitized_anchor_name.Create. It can be used by
existing users and those that look for a small package, and don't need
all of blackfriday functionality. Existing users of blackfriday can use
the new SanitizedAnchorName function directly and avoid an extra
package import.
This change is a port of PR #352 from v1 into v2.
Updates #348.
Updates #350.
* Add full info string in fenced code blocks
According to common mark, the info string for a fenced code block can be any
non-whitespace string, so adjust the code to read a full string instead of
just the syntax name.
Fixes#410 in v2.
* run go fmt
Move reference and footnote extraction code from firstPass to a
paragraph block parser. This makes firstPass a little bit slimmer, ergo
closer to elimination.
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.
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.
The callbacks used to return bools, but none of the actual
implementations return false, always true. So in order to make further
refactorings simpler, make the interface reflect the inner workings: no
more return values, no more conditionals.
This is a better style for a set, since each value can only be present
or absent.
With bool as value type, each value may be absent, or true or false. It
also uses slightly more memory.
Add a call to fenced code block processor inside the loop that's
responsible for collecting the quoted lines. Grok all the fenced code
block as a part of the quoted text.
Closes#122.
Change approach at fixing #45: don't patch input markdown at preprocess
pass, instead improve special case detection when parsing paragraphs.
Leave the fenced code block detection in the preprocess pass though,
it's been put to another use since then, to suppress tab expansion
inside code blocks.
