Exercism Command-line Interface

The CLI provides a way to do the problems on exercism.io.

Important: If you're looking for instructions on how to install the CLI. Please read Installing the CLI

This CLI ships as a binary with no additional runtime requirements. This means that if you're doing the Haskell problems on exercism you don't need a working Python or Ruby environment simply to fetch and submit exercises.

Dependencies

Go version 1.6 or higher

Installing Go

Follow the directions on http://golang.org/doc/install

Development

fork this repo
go get github.com/exercism/cli/exercism
cd $GOPATH/src/github.com/exercism/cli
git remote set-url origin https://github.com/<your-github-username>/cli
go get -t ./...
Make the change.
Submit a pull request.

Please provide tests for the changes where possible.

To run the tests locally, use go test ./...

At the moment the CLI commands are not tested, so if you're adding a new command don't worry too hard about tests.

Testing against exercism.io

If you want to test a change by using your own fork to try exercism commands, such as exercism fetch or exercism submit, against the exercism.io site, it is advisable that you set up and run a local development environment, and configure the CLI to submit to your local machine, which would let you easily delete and recreate submissions, without fear of breaking the exercism.io site.

Building

To build the binary for your platform run

go install github.com/exercism/cli/exercism

go build -o out/exercism exercism/main.go

The resulting binary can be found in out/exercism (Linux, Mac OS X) or out/exercism.exe (Windows).

In order to cross-compile for all platforms, run bin/build-all. The binaries will be built into the release directory.
