Emacs major mode for viewing and editing EOS (tm) configuration

Emacs Mode for EOS Configuration Files

This is an Emacs package to view and edit Arista EOS (tm) configuration files.

EOS-Mode

This provides font-lock highlighting for different keywords, commands, and sections in EOS configuration. It also provides access to configuration sections via Imenu.

The official repository is located at: https://github.com/sfromm/eos-mode.

Installation

You can either clone this repository and add it your load-path or use something like Quelpa or Straight to add to your configuration. The following is one example.

Keying off of a line at the beginning of a file, such as RANCID-CONTENT-TYPE is really helpful to automatically enable the mode.

(use-package eos-mode
  :straight (eos-mode :type git :host github :repo "sfromm/eos-mode")
  :commands (eos-mode)
  :magic ("!RANCID-CONTENT-TYPE: arista" . eos-mode)
  :hook (eos-mode . highlight-indent-guides-mode))

Org-Mode

This can be used with org-mode to perform syntax highlighting.
