Add a command to print portfolio values to stdout for unix style piping

[xomtux]

Background
Currently ticker only provides the data in a graphical user interface. To track portfolios over time or use the collected data in other ways the quotes and summaries should be printed to the stdout in a predefined format like json.

Request
In order to pipe asset and portfolio values into other tools in a CLI context, there should a command to print those values in different formats to the stdout.

Technical Details

• there should be a specific (sub)command to trigger printing to stdout
• flags for this command define which data to export and in what format
• executed with this command, ticker doesn't show the graphical interface, it only prints the collected quotes and summaries

Additional context

An example how this could look like is the "holdings" command in cointop which enables users output only the total value of a portfolio or get the current values in different format like json or csv.

Personally I would still be interested in this feature. But if there is no general interest from other users I can also close the issue and/or create an entry in the Discussion area with an Idea label for future improvement.

Thank you for the suggestion

I can see the value this can bring to folks who need it. I think it would be a good expansion of ticker's functionality but don't believe it to be close enough to the core functionality to personally prioritize building it. A PR adding this would be welcome but I will move this to discussion section for now
