cmark

My personal build of CMark ✏️

Commit: 19a3a5ea4f73e8757b6d208f3be003bc2828e752
Parent: d19558961c1b579ddb2f5c62f1b6a65be3324333
Author: John MacFarlane <jgm@berkeley.edu>
Date: Sun, 28 Dec 2014 17:52:09 -0800

Added end_column to cmark_node struct.

API exports cmark_node_get_column.

XML writer indicates start and end line and column for block-level nodes.
