Atom package: https://atom.io/packages/language-gnuplot-5
This is a fork of language-gnuplot-atom.
The aim of this package is to provide up-to-date support for GnuPlot Syntax in Atom.
I just merged some old PRs from language-gnuplot-atom. I am looking forward to refine the syntax highlighting. Furter PRs are welcome!
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
