CFEngine layer

• Description
• Install
• Configuration
  • Set file permission on save
  • Indendation
  • cfengine3 SRC blocks in org-mode
• Execution of cfengine3 SRC blocks
• Key bindings

Description

This layer makes working with CFEngine policy easier:

• Syntax highlighting
• On the fly syntax checks (via syntax-checking layer)
• Auto completion (via auto-completion layer)
• Execution of cfengine3 SRC blocks in org-mode (via ob-cfengine3 package)

Install

Add cfengine to the dotspacemacs-configuration-layers in your ~/.spacemacs to use this layer.

Configuration

Set file permission on save

Here is a function to set permissions to 600 on save, this can help avoid errors like:

File ./example.cf (owner 1000) is writable by others (security exception)

  (defun cfengine-permissions-policy-owner-only ()
    "If file starts with a shebang, make `buffer-file-name' executable"
    (save-excursion
      (set-file-modes buffer-file-name #o600)
      (message (concat "Made " buffer-file-name " accessibly only by the owner (600)."))))

  (add-hook 'after-save-hook 'cfengine-permissions-policy-owner-only nil 'make-it-local)

Indendation

If you like attributes to be intended from the promiser set Indentation amount from anchor to 2. For example:

  bundle agent main
  {
    vars:

        "promiser"
          string => "value",
          comment => "Indented 2 spaces from promiser";
  }

cfengine3 SRC blocks in org-mode

Add cfengine to the list of languages loaded by org-babel.

  (defun dotspacemacs/user-config ()

    (with-eval-after-load 'org

      (org-babel-do-load-languages
       'org-babel-load-languages
       '(
         (cfengine . t)))
      )
    )

Alternatively configure org-mode to load support for any languages encountered automatically.

  (defun dotspacemacs/user-config ()

    (with-eval-after-load 'org

      (defadvice org-babel-execute-src-block (around load-language nil activate)
        "Load language if needed"
        (let ((language (org-element-property :language (org-element-at-point))))
          (unless (cdr (assoc (intern language) org-babel-load-languages))
            (add-to-list 'org-babel-load-languages (cons (intern language) t))
            (org-babel-do-load-languages 'org-babel-load-languages org-babel-load-languages))
          ad-do-it))
      )
    )

Enable syntax highlighting and tab stops as if you were editing in the native mode within SRC blocks.

  (defun dotspacemacs/user-config ()

    (with-eval-after-load 'org

      (setq org-src-tab-acts-natively t)
      (setq org-src-fontify-natively t)
      )
    )

Execution of cfengine3 SRC blocks

With the insertion point inside the SRC block press ,, or CTRL-c Ctrl-c

  bundle agent main
  {
    reports:

        "Hello World!";
  }

R: Hello World!

See the ob-cfengine3 README for information on controlling inclusion of the stdlib, definition of classes and controlling the bundlesequence using header args.

To suppress the confirmation when executing a block set (setq org-confirm-babel-evaluate nil) in dotspacemacs/user-config().
