leading_separator
boolean
added in 2.11 of ansible.builtin
    Choices:
  • no
  • yes ←
Use in conjunction with keyed_groups.
By default, a keyed group that does not have a prefix or a separator provided will have a name that starts with an underscore.
This is because the default prefix is "" and the default separator is "_".
Set this option to False to omit the leading underscore (or other separator) if no prefix is given.
If the group name is derived from a mapping the separator is still used to concatenate the items.
To not use a separator in the group name at all, set the separator for the keyed group to an empty string instead.
plugin
string / required
    Choices:
  • community.hrobot.robot
Token that ensures this is a source file for the plugin.
strict
boolean
    Choices:
  • no ←

If yes make invalid entries a fatal error, otherwise skip and continue.
Since it is possible to use facts in the expressions they might not always be available and we ignore those errors by default.

  • no ←
  • yes
ini entries:

[inventory_plugins]
