m.logPrint() is working!

<eq> and <eqq> tags are rendered to MathJax format, being enclosed by \ ( \ ) and \ [ \ ].

docuK-1 scripts started!
If this log is not closed automatically, there must be an error somewhere in your document or scripts.

Table of Contents is filled out.

Auto numberings of sections (div.sec>h2, div.subsec>h3, div.subsubsec>h4), <eqq> tags, and <figure> tags are done.

<cite> and <refer> tags are rendered to show bubble reference.

<codeprint> tags are printed to corresponding <pre> tags, only when the tags exist in the document.


Current styles (dark/bright mode, font-family, font-size, line-height) are shown.
