Mode for Junos configuration files

This features junos-mode a mode for editing Junos-like files.

There is currently no configuration knob.

Install

With use-package and quelpa:

(use-package junos-mode
  :quelpa (junos-mode :fetcher github
                      :repo "vincentbernat/junos-mode"
                      :files (:defaults "junos.py"))
  :defer t)

With Doom Emacs:

(package! junos-mode :recipe (:host github
                              :repo "vincentbernat/junos-mode"
                              :files (:defaults "junos.py")))

Integration with org-mode and Babel

It also comes with an integration with org-mode and Babel. It uses a small Python helper to efficiently handle several parallel sessions asynchronously. This helper uses Junos PyEZ.

#+BEGIN_SRC junos :host alfred.exoscale.local
system {
    time-zone Europe/Paris;
}
#+END_SRC

#+RESULTS:
#+begin_example
Load replace: ✓
Checks: ✓

You can also execute CLI commands:

#+BEGIN_SRC junos :host alfred.exoscale.local
show version
#+END_SRC

There are some limitations with this integration. Notably, it expects the output of the execution will be in a block, like above. If you force another representation, this won't work as expected.

This is only compatible with with Org 9. It also requires the UUID module.

Note that the helper program is using Junos PyEZ which doesn't check SSH keys.

A host should use one of the following form:

• host.example.com (default user from ~/.ssh/config and authentication with SSH key)
• user@host.example.com (authentication with SSH key)
• user:password@host.example.com (authentication with password)

Demo
