We’ve built a basic dbt-flavored highlighter for atom!
It highlights jinja within sql, yaml, and markdown files, and it also includes a number of standard and dbt-specific jinja snippets.

UPDATE: It’s now a published Atom package, with even MOAR snippets! You can install it the way you would any other package – just go to Packages > Settings View > Install Packages and search for atom-dbt¹.
Check out the source code here – pull requests welcome!
¹If you had already installed the package by cloning and using apm link, first run apm uninstall atom-dbt from your command line before installing the published package
