# Blogging from the command line

This post is composed in the text editor Vim, using the L^{A}T_{E}X format and converted to HTML using H^{E}V^{E}A. 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 H^{E}V^{E}A, default H^{E}V^{E}A rendering or using the L^{A}T_{E}X plugin installed in WordPress. The following compares the result produced by each of these three methods.

### H^{E}V^{E}A image

### H^{E}V^{E}A translation

âˆ‘_{i=1}* ^{n} i* =

*n*(

*n*+1)/2

### WordPress image

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