# Blogging from the command line

This post is composed in the text editor Vim, using the LATEX format and converted to HTML using HEVEA. The HTML source is posted on this blog using the blogpost command line tool.

Using such a pipeline, there are several ways to produce mathematical equations. Either using images produced by HEVEA, default HEVEA rendering or using the LATEX plugin installed in WordPress. The following compares the result produced by each of these three methods.

### HEVEA translation

i=1n i = n(n+1)/2

### WordPress image

$\sum_{i=1}^n i = \frac{n(n+1)}{2}$
