# `ActiveSupport::Duration#human_string`

Convert [ActiveSupport::Duration](https://api.rubyonrails.org/classes/ActiveSupport/Duration.html) objects to human-friendly strings like `'2h 30m 17s'`.

- Like [`distance_of_time_in_words`](https://api.rubyonrails.org/classes/ActionView/Helpers/DateHelper.html) helper but _exact_ rather than approximate.
- Like [`#inspect`](https://github.com/rails/rails/blob/b9ca94caea2ca6a6cc09abaffaad67b447134079/activesupport/lib/active_support/duration.rb#L372) but more concise and configurable.
- Like [`#iso8601`](https://api.rubyonrails.org/classes/ActiveSupport/Duration.html#method-i-iso8601) but more human readable rather than machine readable.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'activesupport-duration-human_string'
```

## Usage

```ruby
    duration = ActiveSupport::Duration.build(65)
    duration.human_str                            # =>  '1m 5s'
    duration.human_str(use_2_digit_numbers: true) # =>  '1m 05s'

    duration = ActiveSupport::Duration.build(3500)
    duration.human_str                 # =>  '58m 20s'
    duration.human_str(delimiter: '')  # =>  '58m20s'
    duration.human_str(separator: ' ') # =>  '58 m 20 s'
    duration.human_str(delimiter: ', ', separator: ' ') # =>  '58 m, 20 s'
```

Also aliased as `human_string`, `to_human_s`.

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
