Why use `cmark` and not X?
==========================
`hoedown`
---------
`hoedown` (which derives from `sundown`) is slightly faster
than `cmark` in our benchmarks (0.21s vs. 0.29s). But both
are much faster than any other available implementations.
`hoedown` boasts of including "protection against all possible
DOS attacks," but there are some chinks in the armor:
% time python -c 'print(("[" * 50000) + "a" + ("]" * 50000))' | cmark
...
user 0m0.073s
% time python -c 'print(("[" * 50000) + "a" + ("]" * 50000))' | hoedown
...
0m17.84s
`hoedown` has many parsing bugs. Here is a selection (as of
v3.0.3):
% hoedown
- one
- two
1. three
^D
<ul>
<li>one
<ul>
<li>two</li>
<li>three</li>
</ul></li>
</ul>
% hoedown
## hi\###
^D
<h2>hi\</h2>
% hoedown
[ΑΓΩ]: /φου
[αγω]
^D
<p>[αγω]</p>
% hoedown
```
[foo]: /url
```
[foo]
^D
<p>```</p>
<p>```</p>
<p><a href="/url">foo</a></p>
% hoedown
[foo](url "ti\*tle")
^D
<p><a href="url" title="ti\*tle">foo</a></p>
% ./hoedown
- one
- two
- three
- four
^D
<ul>
<li>one
<ul>
<li>two</li>
<li>three</li>
<li>four</li>
</ul></li>
</ul>
`discount`
----------
`cmark` is about six times faster.
`kramdown`
----------
`cmark` is about a hundred times faster.
`kramdown` also gets tied in knots by pathological input like
python -c 'print(("[" * 50000) + "a" + ("]" * 50000))'
