## What is the purpose of the change This PR is a part of FLIP-189 about prompt customization. There are left and right prompt which could be customized in the same way. Left prompt could be customized via `sql-client.display.prompt.pattern` property and right prompt via `sql-client.display.right-prompt.pattern`. There is a number of things which could be done: different datetime patterns (compatible with SimpleDateFormat), colors, styles, showing current database and catalog, showing specified current property's values. Examples: ``` -- change left prompt to "my_prompt>" SET 'sql-client.display.prompt.pattern'='my_prompt>'; -- show current database in prompt like "default_database prompt>" SET 'sql-client.display.prompt.pattern'='\d prompt>'; -- show current catalog in prompt like "default_catalog prompt>" SET 'sql-client.display.prompt.pattern'='\c prompt>'; -- show current timestamp in prompt like "2022-04-21 11:11:39.071 prompt>" SET 'sql-client.display.prompt.pattern'='\D prompt>'; -- show property value like "localhost prompt>" SET 'sql-client.display.prompt.pattern'='\:taskmanager.host\: prompt>'; -- apply style and colors SET 'sql-client.display.prompt.pattern'='\[f-rgb:#aaaaaa,bold\]\:taskmanager.host\: \[f:g,underline\]prompt>'; ``` The same could be applied to right prompts. The whole range is covered in documentation with some examples at [1] Also there are some details at FLIP's page [2] [1] https://github.com/apache/flink/pull/17830/files#diff-c12a360080e42a64d69dd6c65fd8af77c0d6ef337fa7833c3a8b16b1759d1a11R237-R281 [2] https://cwiki.apache.org/confluence/display/FLINK/FLIP-189%3A+SQL+Client+Usability+Improvements#FLIP189:SQLClientUsabilityImprovements-Supportedpromptoptions(bothforleftandrightprompts) ## Brief change log - Enable left and right prompt customization via properties - Enable styles, property values, datetime patterns compatible with SimpleDateFormat ## Verifying this change There is a class with tests `org.apache.flink.table.client.cli.PromptHandlerTest` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
