Structured output

[mrdavidlaing]

I'd like to be able to extract the list of calendar events into some form of structured output ( so I can import into a spreadsheet for further processing ).

Currently I generate a list like this:

calendar-assistant show [email protected] "2019-01-01..2019-02-01"
[email protected] (all times in Europe/Dublin)

2019-01-02 - 2019-01-05   | XXX treat cases as severity 1 until 1/5/2019 (self)
2019-01-04  22:00 - 23:00 | XXXX 2.1 to 2.2 (Upgrade) (self)
2019-01-07 - 2019-01-09   | XXX Upgrade 2 to 2.1 (not-busy, self)

I'd like to be able to pass a "format" argument to specify the output format - maybe CSV or JSON - eg:

calendar-assistant show [email protected] "2019-01-01..2019-02-01" --format=csv
[email protected] (all times in Europe/Dublin)

start_date,end_date,title
2019-01-02,2019-01-05,"XXX treat cases as severity 1 until 1/5/2019 (self)"
2019-01-04 T22:00,2019-01-04T23:00,"XXXX 2.1 to 2.2 (Upgrade) (self)"
2019-01-07,2019-01-09,"XXX Upgrade 2 to 2.1 (not-busy, self)"

David and I are going to try to pair on this tomorrow.

Thinking about this using the Mikado Method today:

@mikfreedman would love your thoughts on how to approach the solution? Otherwise will hack at it until I find something I'm happy with.

WIP is at branch 123-csv-output

It looks like you're on the right track. I tried to build the presenter nonsense out so that it was swappable at runtime.

you can see the difference in lib/calendar_assistant/cli/commands.rb

      #162
      def show(datespec = "today")
        calendar_assistant(datespec) do |ca, date, out|
          event_set = ca.find_events date
          out.print_events ca, event_set
        end
      end

vs an explicit presenter for linting.

      #144
      def lint(datespec = "today")
        calendar_assistant(datespec) do |ca, date, out|
          event_set = ca.lint_events date
          out.print_events ca, event_set, presenter_class: CalendarAssistant::CLI::LinterEventSetPresenter
        end
      end

[mikfreedman]

so it should be as simple as fiddling some flags and then writing a new presenter like EventSetPresenter and LinterEventSetPresenter. Let me know if you need more info!

FWIW, I was planning to move all list/show event type commands to the same pattern to reduce the logic in cli/commands.rb and cli/printer.rb but never got there. If you have the energy maybe take a crack?
