# tasks file for dotqmail

# To decide wether a dotqmail file is still needed we need to get all files
- name: Fetch all present dotqmail files
  find:
    paths: "{{ansible_env.HOME}}/"
    patterns: "{{dotqmail_prefix}}*"
    hidden: True
  register: present_files

# To decide which file could be deleted we extract first the file name of
# current file with basename(path) and then replace the dotqmail_prefix in it
# with the empty string via replace(dotqmail_prefix,'') to get the dotqmail
# extention
# Then we check up if a member with this extenion is defined in our
# dotqmail_files dict. If not, we can finaly delete the file (current item) via
# item.path
- name: Delete unconfigured (old) files
  file:
    path: "{{item.path}}"
    state: absent
  vars:
    current_ext: "{{item.path|basename|replace(dotqmail_prefix,'')}}"
  with_items: "{{present_files.files}}"
  when: dotqmail_files[current_ext] is not defined

# Going forward to create/update files with config
# Since the root file has no extention we need to treat it separately
# The content lines are configured in list dotqmail_rootfile

# For the other files the we get a key-value pair with the dotqmail extention
# as key and the list of lines as value while looping over dotqmail_files
# (which is a combination of dotqmail_config_files from inventory over
# dotqmail_default_files from role defaults)
