earthly-spacemacs-layer

Syntax highlight for Earthfiles in Spacemacs

How to use

Evaluate the earthly-mode/syntax-highlighter.el file in Emacs (, e b)

Then open an Earthly file and SPC earthly-mode RET.

Plan

Write a syntax highlighter + auto-completion layer for Earthfiles for Spacemacs.

Features (in order of importance)

• Syntax highlighting
• auto-completion (including target names)
• Built in pop-up docs
• Jump to target (bonus points for other files) with SPC j
• call target from within file , e t (, evaluate target)
• maybe color successful targets/cached targets? Seems hard
