ISO-639-2 list of languages and their directions

I collated a list of the languages (ISO-639-2) and the direction they are most commonly written in and provided it as a TXT or CSV file for download here: https://github.com/webmasterar/languagesWithDirections

Examples:

ara,,ar,Arabic,arabe,rtl
chi,zho,zh,Chinese,chinois,ttb
eng,,en,English,anglais,ltr

This is mostly useful with the correctly displaying text on websites using the HTML bdo tag or CSS styles direction and/or writing-mode.
