Why Dart?

I like Dart because it's a modern programming language. Most people associated it with client-side web programming, but Dart also has a powerful server side VM, which I use for this project.

This is a command line dart app (bin/kata.dart) which calls into a library. The library handles data parsing and queries. It supports one predefined query 'smallest_spread' which can be run against any loosely columned textual data that contains a well-formed header row.

The library can be found here: https://github.com/prujohn/kata04-util

Assumptions

That you have dart installed. www.dartlang.org

Usage

dart kata.dart --help

Running A Query

For the weather.dat file:

dart kata.dart --ignorelast --query=smallest_spread --url=http://codekata.com/data/04/weather.dat --cols=MnT,MxT --disp=Dy --coerce

For the football.dat file:

dart kata.dart --query=smallest_spread --url=http://codekata.com/data/04/football.dat --cols=F,A --disp=Team --coerce

Compliance

Use Gradle wrapper

Dart uses a package/manifest tool called "pub" for this. See pubspec.yaml

Set up a basic project

Done.

Package your project, complete with manifest information

Dart's pub tool handles this. See pubspec.yaml

Have a proper dependency handling to external libraries

Dependencies are listed in pubspec.yaml

Publish Test Report, also, print test execution outcome to command line so it's visible on the Travis CI console log

Done.
