URLShortener leverages tinyurl to shorten provided URLs. They are also cached so future requests will not make a network request.
There are a few main ways to run this application.
1. Double click on the Package.swift file to open up Xcode, running normally will start the interactive mode. To run with different options
Edit the Scheme and set the arguments passed on launch.
2. From terminal in the application directory use: swift run URLShortener to enter interactive mode. For one offs use swift run URLShortener -u http://url.com
3. Install the application in your computers system path.
swift build --configuration release
cp -f .build/release/URLShortener /usr/local/bin/urlshortener
To see the help instructions run the app with the -h flag. (swift run URLShortener -h)
To see a list of the top cached URLs use the -t flag with an optional limit Int value. The default is 3 (swift run URLShortener -t 5)
For a look at code coverage it is best to run the tests in Xcode by opening the Package.swift and enabling Code Coverage under test -> Options. It is also possible to generage JSON or lcov which requires installing additional tools from the terminal.
To run tests from the terminal without code coverage run swift test from the packages directory.
To run inside Xcode just hit Command + U.
There are pretty much complete tests for FileManagerExtensions.swift, TinyURL.swift, URLCache.swift.
With this being the first ever console application I have written in swift I got stuck a bit writing tests for the Console portion of this app.
NOTE: For a production version of a console tool I where I could use third party software I would leverage: https://github.com/apple/swift-argument-parser, which would allow the code to be much more extendable as well as testable.
