Ansible formatters filter plugins for parted

Adds two filter plugins:

• parted_human_readable
• parted_human_to_bytes

History

These plugins are used to convert partition size in bytes to parted-compatable format.

Parted (as its Ansible module wrapper) supports both Kilobytes (SI prefix) and Kibibytes.
Ansible considers GB a Gibibyte while Parted interprets is as a Gigabyte.
Also Parted is case-sensitive and doesn't support space separator for taken values.

Code is based on official Ansible filters for size convertions.

Installation

Common for custom Ansible filter plugins.

Use

Parted Human Readable

Asserts whether the given string is human readable or not.

For example:

- name: "Parted Human Readable"
  assert:
    that:
      - '"1.00 Bytes" == 1|parted_human_readable'
      - '"1.00 bits" == 1|parted_human_readable(isbits=True)'
      - '"10.00 KB" == 10000|parted_human_readable'
      - '"97.66 MB" == 97660000|parted_human_readable'
      - '"0.10 GB" == 100000000|parted_human_readable(unit="G")'
      - '"0.10 Gb" == 100000000|parted_human_readable(isbits=True, unit="G")'
      - '"10.00 KiB" == 10240|parted_human_readable(iskibi=True)'
      - '"97.66 MiB" == 102400000|parted_human_readable(iskibi=True)'
      - '"0.10 GiB" == 107374182|parted_human_readable(iskibi=True, unit="Gi")'
      - '"0.10 Gib" == 107374182|parted_human_readable(iskibi=True, isbits=True, unit="Gi")'
      - '"0.10GiB" == 107374182|parted_human_readable(iskibi=True, unit="Gi", spaceseparator=False)'

This would result in:

{ "changed": false, "msg": "All assertions passed" }

Parted Human to Bytes

Returns the given string in the Bytes format.

For example:

- name: "Parted Human to Bytes"
  assert:
    that:
      - "{{'0'|parted_human_to_bytes}}        == 0"
      - "{{'0.1'|parted_human_to_bytes}}      == 0"
      - "{{'0.9'|parted_human_to_bytes}}      == 1"
      - "{{'1'|parted_human_to_bytes}}        == 1"
      - "{{'10.00 KB'|parted_human_to_bytes}} == 10000"
      - "{{   '11 MB'|parted_human_to_bytes}} == 11000000"
      - "{{  '1.1 GB'|parted_human_to_bytes}} == 1100000000"
      - "{{'10.00 Kib'|parted_human_to_bytes(iskibi=True, isbits=True)}} == 10240"
      - "{{'10.00 KiB'|parted_human_to_bytes(iskibi=True)}} == 10240"
      - "{{   '11 MiB'|parted_human_to_bytes(iskibi=True)}} == 11534336"
      - "{{  '1.1 GiB'|parted_human_to_bytes(iskibi=True)}} == 1181116006"

This would result in:

{ "changed": false, "msg": "All assertions passed" }
