* Description
This layer adds support for editing Ansible configuration files in Spacemacs.

** Features:
- Syntax highlighting for Ansible-flavored YAML and Jinja2 templates.
- Auto-completion via =company-ansible=.
- Integration of =ansible-vault= into emacs for automatic encryption/decryption of files.

* Install
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =ansible= to the existing =dotspacemacs-configuration-layers= list in this
file.

* Configuration
** ansible-vault
*** Password
To use =ansible-vault= you have to provide the path to a file containing the
password to use somewhere in your =dotspacemacs/user-config= function.
For instance:

#+BEGIN_SRC emacs-lisp
  (setq ansible::vault-password-file "path/to/pwd/file")
#+END_SRC

The default value is the ansible-vault default value: =~/.vault_pass.txt=.

For now Ansible does not handle multiple passwords in the vault file
(see [[https://github.com/ansible/ansible/issues/13243]]). To work around this
limitation directory local variables can be used to define a different
password file for a given environment. Example:

#+BEGIN_SRC emacs-lisp
  ;;; Directory Local Variables
  ;;; For more information see (info "(emacs) Directory Variables")

  ((yaml-mode . ((ansible::vault-password-file . "path/to/vault_file"))))
#+END_SRC

*** Automatic encryption and decryption
This layer comes preconfigured with automatic encryption/decryption of
encrypted files using =ansible-vault= so it is possible to edit seamlessly
any encrypted files.

If you want to disable this feature then set the layer variable
=ansible-auto-encrypt-decrypt= to =nil=.

#+BEGIN_SRC emacs-lisp
  (ansible :variables ansible-auto-encrypt-decrypt t)
#+END_SRC
