How to use latex equation environment in Pandoc Markdown?

Question

In Pandoc markdown, I can use \'$$\' to start a display math environment. However, these equations are not numbered in latex so I hope to use the equation environment instead, l

Answer 1

Try the pandoc-eqnos filter. Labels may be attached to equations using attributes:

 $$ y = mx +b $$ {#eq:description}

... and then referenced like this:

@eq:description

For tex/pdf output, LaTeX's native equation environment and \label and \ref macros are used; for all others the numbers are hard-coded.

Instructions are given on the pandoc-eqnos page for how to install and apply the filter.
