sekikn opened a new pull request #6400: [AIRFLOW-5731] Make output format from list commands configurable URL: https://github.com/apache/airflow/pull/6400 Make sure you have checked _all_ steps below. ### Jira - [x] My PR addresses the following [Airflow Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR" - https://issues.apache.org/jira/browse/AIRFLOW-5731 - In case you are fixing a typo in the documentation you can prepend your commit with \[AIRFLOW-XXX\], code changes always need a Jira issue. - In case you are proposing a fundamental code change, you need to create an Airflow Improvement Proposal ([AIP](https://cwiki.apache.org/confluence/display/AIRFLOW/Airflow+Improvements+Proposals)). - In case you are adding a dependency, check if the license complies with the [ASF 3rd Party License Policy](https://www.apache.org/legal/resolved.html#category-x). ### Description - [x] Here are some details about my PR, including screenshots of any UI changes: Currently, list commands such as `airflow connections list` and `airflow users list` display prettily formatted tables, but they are not so suitable for parsing and processing. With this PR, users can get easier-to-parse output, as follows: ``` $ airflow connections list --tablefmt=simple 2>/dev/null | head Conn Id Conn Type Host Port Is Encrypted Is Extra Encrypted Extra ------------------------------ --------------------------- ------------------------- ------ -------------- -------------------- ------------------------------ 'airflow_db' 'mysql' 'mysql' None False False None 'local_mysql' 'mysql' 'localhost' None True False None 'presto_default' 'presto' 'localhost' 3400 False False None 'google_cloud_default' 'google_cloud_platform' None None False False None 'hive_cli_default' 'hive_cli' 'localhost' 10000 False True 'gAAAAABdrxCP...jMAQ6LknDM8pc' 'pig_cli_default' 'pig_cli' None None False False None 'hiveserver2_default' 'hiveserver2' 'localhost' 10000 False False None 'metastore_default' 'hive_metastore' 'localhost' 9083 False True 'gAAAAABdrxCP...ABWevIJL-Dto=' $ airflow connections list --tablefmt=tsv 2>/dev/null | head Conn Id Conn Type Host Port Is Encrypted Is Extra Encrypted Extra 'airflow_db' 'mysql' 'mysql' None False False None 'local_mysql' 'mysql' 'localhost' None True False None 'presto_default' 'presto' 'localhost' 3400 False False None 'google_cloud_default' 'google_cloud_platform' None None False False None 'hive_cli_default' 'hive_cli' 'localhost' 10000 False True 'gAAAAABdrxCP...jMAQ6LknDM8pc' 'pig_cli_default' 'pig_cli' None None False False None 'hiveserver2_default' 'hiveserver2' 'localhost' 10000 False False None 'metastore_default' 'hive_metastore' 'localhost' 9083 False True 'gAAAAABdrxCP...ABWevIJL-Dto=' 'mongo_default' 'mongo' 'mongo' 27017 False False None ``` ### Tests - [x] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: test_cli_list_users_with_args test_cli_list_roles_with_args test_cli_list_jobs_with_args (added arguments to the existing test) test_cli_connections_list_with_args test_pool_list test_pool_list_with_args ### Commits - [x] My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)": 1. Subject is separated from body by a blank line 1. Subject is limited to 50 characters (not including Jira issue reference) 1. Subject does not end with a period 1. Subject uses the imperative mood ("add", not "adding") 1. Body wraps at 72 characters 1. Body explains "what" and "why", not "how" ### Documentation - [x] In case of new functionality, my PR adds documentation that describes how to use it. - All the public functions and the classes in the PR contain docstrings that explain what it does - If you implement backwards incompatible changes, please leave a note in the [Updating.md](https://github.com/apache/airflow/blob/master/UPDATING.md) so we can assign it to a appropriate release
