module: ini_file
short_description: Tweak settings in INI files
extends_documentation_fragment: files
description:
- Manage (add, remove, change) individual settings in an INI-style file without having
to manage the file as a whole with, say, M(ansible.builtin.template) or M(ansible.builtin.assemble).
- Adds missing sections if they don't exist.
- Before Ansible 2.0, comments are discarded when the source file is read, and therefore will not show up in the destination file.
- Since Ansible 2.3, this module adds missing ending newlines to files to keep in line with the POSIX standard, even when
no other modifications need to be applied.
options:
path:
description:
- Path to the INI-style file; this file is created if required.
- Before Ansible 2.3 this option was only usable as I(dest).
type: path
required: true
aliases: [ dest ]
section:
description:
- Section name in INI file. This is added if I(state=present) automatically when
a single value is being set.
- If left empty or set to C(null), the I(option) will be placed before the first I(section).
- Using C(null) is also required if the config format does not support sections.
type: str
required: true
option:
description:
- If set (required for changing a I(value)), this is the name of the option.
- May be omitted if adding/removing a whole I(section).
type: str
value:
description:
- The string value to be associated with an I(option).
- May be omitted when removing an I(option).
- Mutually exclusive with I(values).
- I(value=v) is equivalent to I(values=[v]).
type: str
values:
description:
- The string value to be associated with an I(option).
- May be omitted when removing an I(option).
- Mutually exclusive with I(value).
- I(value=v) is equivalent to I(values=[v]).
type: list
elements: str
version_added: 3.6.0
backup:
description:
- Create a backup file including the timestamp information so you can get
the original file back if you somehow clobbered it incorrectly.
type: bool
default: false
state:
description:
- If set to C(absent) and I(exclusive) set to C(true) all matching I(option) lines are removed.
- If set to C(absent) and I(exclusive) set to C(false) the specified I(option=value) lines are removed,
but the other I(option)s with the same name are not touched.
- If set to C(present) and I(exclusive) set to C(false) the specified I(option=values) lines are added,
but the other I(option)s with the same name are not touched.
- If set to C(present) and I(exclusive) set to C(true) all given I(option=values) lines will be
added and the other I(option)s with the same name are removed.
type: str
choices: [ absent, present ]
default: present
exclusive:
description:
- If set to C(true) (default), all matching I(option) lines are removed when I(state=absent),
or replaced when I(state=present).
- If set to C(false), only the specified I(value(s)) are added when I(state=present),
or removed when I(state=absent), and existing ones are not modified.
type: bool
default: true
version_added: 3.6.0
no_extra_spaces:
description:
- Do not insert spaces before and after '=' symbol.
type: bool
default: false
create:
description:
- If set to C(false), the module will fail if the file does not already exist.
- By default it will create the file if it is missing.
type: bool
default: true
allow_no_value:
description:
- Allow option without value and without '=' symbol.
type: bool
default: false
notes:
- While it is possible to add an I(option) without specifying a I(value), this makes no sense.
- As of Ansible 2.3, the I(dest) option has been changed to I(path) as default, but I(dest) still works as well.
- As of community.general 3.2.0, UTF-8 BOM markers are discarded when reading files.
