Add this line to your application's Gemfile:

gem 'sniper_links'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install sniper_links

email = "marlon.rando@gmail.com"
from  = "us@our.domain"

snipe = SniperLinks.new(email) # => SniperLinks
snipe.sniper_link_strategy     # => SniperLinks::Strategies::GMail
snipe.sniper_link(from)        # => URI

puts snipe.sniper_link.to_s
# => https://mail.google.com/mail/u/0/#search/from%3A%28us%40our.domain%29%2Bin%3Aanywhere%2Bnewer_than%3A1h

If you want to use a strategy directly, you can do so like so:

email = "rando.calrissian@foo.com"
from  = "us@our.domain"

snipe = SniperLinks.new(email) # This will raise an error
# Traceback (most recent call last):
# ....
# SniperLinks::Error (Unsupported email domain)

snipe = SniperLinks::Strategies::GMail.new(email) # => SniperLinks::Strategies::GMail
snipe.sniper_link(from)                           # => URI

We support the following email service provider platforms:

• Gmail - *@gmail.com
• Outlook - *@outlook.com
• Yahoo - *@yahoo.* or *@myyahoo.*
• ProtonMail - *@protonmail.com, *@proton.me, *@protonmail.ch, or *@pm.me
• iCloud - *@icloud.com, *@me.com, or *@mac.com
• Hey.com - *@hey.com
• AOL - *@aol.com
• Mail.ru - *@mail.ru

Each email service provider has its own sniper link strategy. The following table shows how much functionality is supported by each provider.

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.

• Add support for more email service providers, like Fastmail, etc.
• Add support for selecting a strategy based on the email address domain's MX records.
