Durationformatter: Feature proposal

Durationformatter Feature proposal

Feature proposal

The DtDurationFormatter converts an input duration to an output duration. Both
the input and output units are configurable. Additionally, it has support for
precision/mode concerning how the output is displayed.

Precisionmodes

• DEFAULT || undefined: Default mode
• PRECISE: Precise
• 1 - n: Amount of units to display

Pipesyntax:

{{ <input /> || dtDuration: '<formattingMethod>':'<outputUnit>':'<inputUnit>' }}

The duration formatter pipe will cover the use cases below:

Default mode:

It will only display two units from the biggest unit that has a value.
InputUnit is set to milliseconds by default

• outputUnit not specified ('DEFAULT':undefined:undefined):

  • input (milliseconds): 61 001
  • output: 1 min 1 s 1 ms
  • precisionMode: "DEFAULT" OR undefined

• outputUnit not specified ('DEFAULT':undefined:undefined):

  • input(milliseconds): 3 661 001
  • ouput: 1 h 1 min 1 s
  • precisionMode: "DEFAULT" OR undefined

• outputUnit specified ('DEFAULT' :'s': undefined):

  • input (milliseconds): 1 500
  • output (seconds): 1 s
  • precisionMode: "DEFAULT" OR undefined

• outputUnit specified ('DEFAULT' :'s': undefined):

  • input (milliseconds): 500
  • output (seconds): < 1 s
  • precisionMode: "DEFAULT" OR undefined

• outputUnit specified AND inputUnit specified ('DEFAULT':'s':'h'):

  • input (hour): 3
  • output (seconds): 10800 s
  • precisionMode: "DEFAULT" OR undefined

Precise mode:

• outputUnit not specified:

  • input (milliseconds): 1500
  • output: 1500 ms
  • precisionMode: "PRECISE"

• outputUnit is seconds:

  • input (milliseconds): 1 500
  • output (seconds): 1.5 s
  • precisionMode: "PRECISE"

Custom amount of displayed units

• Precision set to 2:

  • input(milliseconds): 90 061 001
  • output: 1 d 1 h
  • precisionMode: 2

• Precision set to 5:

  • input(milliseconds): 90 061 001
  • output: 1 d 1 h 1 min 1 s 1 ms
  • precisionMode: 5

What should happen if the input is smaller than the output unit?
E.g.:

• Input: 1 (ms)
• outputUnit: seconds
• Output: ?
  I'd suggest displaying '< 1 {Unit}', but this should be at least defined.

And to double-check: What happens if the input is zero?
Will it display '0 {Unit}'?

Will this also work for rate units?
E.g.: CPU time -> 10 s/min

Good point.
IMO it should be compatible with the dtRate formatter.

@dlaubi-dt Good morning, first I want to apologize for the late response. I couldn't come to the office on Friday.
There are two outputs possible by giving the pipe another attribute which sets the formation mode:

DEFAULT || undefined

• Input: 1ms
• outputUnit: seconds
• Output: < 1s

PRECISE

• Output: 0.001s

@jsjsat (&& @dlaubi-dt) Good morning, can you elaborate on the rate s/min? I'm not quite sure what that means tbh ^^
But since Angular supports chaining pipes, I think that with a little string formatting magic, it should work. (Will test this out and keep you up to date if you want)
