PbSyringe

Supports Dependency Injection about Progressbar.

Add this line to your application's Gemfile:

gem 'pb_syringe'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pb_syringe

1. Include PbSyringe::Progressable to your object.

   require "pb_syringe"
   
   class SampleClass
       include PbSyringe::Progressable
   
   end
   

   PbSyringe::Progressable implements progress_start, progress_increment, progress_finish methods that you can call when you want progressbar expression.

2. Implements concrete PbSyringe::ProgressUnit class that behaves Progressbar you want.

   class AwesomeProgressBar < PbSyringe::ProgressUnit
       def start(**options)
           # TODO: init progressbar
           # called when you call progress_start of Progressable object method.
       end
   
       def progress_increment(count)
           # TODO: adjust progressbar's progress
           # called when progress_increment called.
       end
   
       def progress_finish
           # TODO: finish progress bar
           # called when progress_finish called.
       end
   end
   

3. assign ProgressUnit to Progressable Object (Dependency Injection)

   sample = SampleClass.new
   unit = AwesomeProgressBar.new
   
   ### PbSyringe provides `PbSyringe::AnsiProgressbarUnit` using `ANSI::Progressbar`, might be useful for rake task.
   ### And it is a sample implementation of ProgressUnit.
   ### If you want to try, check below.
   ### require "pb_syringe/ansi_progressbar_unit"
   ### unit = PbSyringe::AnsiProgressbarUnit.new
   
   sample.progress_unit = unit
   
   sample.progress_start(label: "test", total: 100)
   
   100.times do |i|
       sample.progress_increment(i + 1)
   end
   
   sample.progress_finish
   
   # block style calls finish after yield block
   sample.progress_start(label: "test", total: 100) do
       100.times do |i|
           sample.progress_increment(i + 1)
       end
   end
