# A Quick Markdown Syntax Error Detection for Writing MathJax Equations in Octopress Posts (4)

## Background

I’m recently enhancing the $\rm \LaTeX$ code for inline limits. For the reason of doing so, you may refer to the external link of my recent linklog Inline Limit Rendering.

## Problem

In the previous post in this series written over one year ago, I have included a code block which enables deferred MathJax loading. However, I manually added this chuck of code in the HTML file generated by kramdown, which created the problem described in the next subsection A problem with Vim’s folding arised.

## Solution

Firstly, save the code for loading MathJax in the previous post in this series in a separate file ~/script.html. Then use the following commands within Vim in order to avoid leaving the current buffer and to improve efficiency.

9,\$w! ~/temp.mkd
!kramdown ~/temp.mkd > ~/temp.html
!cat ~/{temp,script}.html > ~/test.html


The digit 9 in the first command isn’t exact. Change it to any line number that separates the yaml front matter from the post content.
