This is a test of various filter plugins found in Ansible (ex: core.py), and
|
|
not so much a test of the core filters in Jinja2.

Dumping the same structure to YAML
|
|
|
|
{{ some_structure | to_nice_yaml }}
|
|
|
|
Dumping the same structure to JSON, but don't pretty print
|
|
|
|
{{ some_structure | to_json(sort_keys=true) }}

Dumping the same structure to YAML, but don't pretty print

From a recorded task, the changed, failed, success, and skipped
|
|
tests are shortcuts to ask if those tasks produced changes, failed,
|
|
succeeded, or skipped (as one might guess).
|
|
|
|
Changed = {{ some_registered_var is changed }}
|
|
Failed = {{ some_registered_var is failed }}
|
|
Success = {{ some_registered_var is successful }}
|
|
Skipped = {{ some_registered_var is skipped }}
|
|
|
|
The mandatory filter fails if a variable is not defined and returns the value.
|
|
To avoid breaking this test, this variable is already defined.
|
|
|
|
a = {{ a | mandatory }}
|
|
|
|
There are various casts available
|
|
|
|
int = {{ a | int }}
|
|
bool = {{ 1 | bool }}
|
|
|
|
String quoting
|
|
|
|
quoted = {{ 'quoted' | quote }}
|
|
|
|
The fileglob module returns the list of things matching a pattern.
|
|
|
|
fileglob = {{ (playbook_dir + '/files/fileglob/*') | fileglob | map('basename') | sort | join(', ') }}
|
|
|
|
There are also various string operations that work on paths. These do not require
|
|
files to exist and are passthrus to the python os.path functions
|
|
|
|
/etc/motd with basename = {{ '/etc/motd' | basename }}
|
|
/etc/motd with dirname = {{ '/etc/motd' | dirname }}
|
|
|
|
path_join_simple = {{ ('/etc', 'subdir', 'test') | path_join }}
|
|
path_join_with_slash = {{ ('/etc', 'subdir', '/test') | path_join }}
|
|
path_join_relative = {{ ('etc', 'subdir', 'test') | path_join }}
|
|
path_join_merged = {{ ('/etc', 'subdir//test') | path_join }}

TODO: realpath follows symlinks. There isn't a test for this just now.

TODO: add tests for set theory operations like union

regex_replace = {{ 'foo' | regex_replace('^foo', 'bar') }}
|
