jthomas opened a new issue #178: Add flag for retrieving action parameter values URL: https://github.com/apache/incubator-openwhisk-cli/issues/178 ## issue As a developer, I often need to check the default parameters on an action. Using the CLI tool, I have to retrieve the entire action definition as the `--summary` flag only lists parameter names not values. This is problematic when using actions with binary packages. For example, using a Node.js action with bundled dependencies means the `exec.code` field in the response to `wsk action get <name>` is multiple MBs of base64-encoded text. Dumping this much JSON to the console is slow and difficult to parse. This is what my screen often looks like... <img width="1440" alt="screen shot 2017-12-19 at 16 00 35" src="https://user-images.githubusercontent.com/2322/34166037-c5618f96-e4d5-11e7-8b01-af4a84bf11b4.png";> This is a jarring and poor developer experience. ## potential solutions? - Add a `-p | --param` flag to `wsk action get` like the `url` flag to retrieve only the params. ``` $ wsk action get name --params ok: got action name { "key": "actions", "value": [ "hello-world" ] } ``` - Extend `--summary` to show parameter values along with names. ``` $ wsk action get params --summary action /[email protected]_dev/params: Returns a result based on parameter hello (parameters: *hello=world) ``` Having the `--summary` flag show values would be simpler but I'm not sure of a sensible way to show all the possible parameter value types in a concise format. **I'll open a PR for the `--params` flag to start with unless people have other suggestions?.**
