Binaries

Go Ethereum comes with several binaries found in cmd:

mist Official Ethereum Browser
ethereum Ethereum CLI
ethtest test tool which runs with the tests suit: ethtest "cat myfile.json".
evm is a generic Ethereum Virtual Machine: evm -code 60ff60ff -gas 10000 -price 0 -dump. See -h for a detailed description.

Contribution

If you'd like to contribute to Ethereum please fork, fix, commit and send a pull request. Commits who do not comply with the coding standards are ignored (use gofmt!). If you send pull requests make absolute sure that you commit on the develop branch and that you do not merge to master. Commits that are directly based on master are simply ignored.

To make life easier try git flow it sets this all up and streamlines your work flow.

Coding standards

Sources should be formatted according to the Go Formatting Style.

Unless structs fields are supposed to be directly accesible, provide Getters and hide the fields through Go's exporting facility.

When you comment put meaningfull comments. Describe in detail what you want to achieve.

wrong

// Check if the value at x is greater than y
if x > y {
    // It's greater!
}

Everyone reading the source probably know what you wanted to achieve with above code. Those are not meaningful comments.

While the project isn't 100% tested I want you to write tests non the less. I haven't got time to evaluate everyone's code in detail so I expect you to write tests for me so I don't have to test your code manually. (If you want to contribute by just writing tests that's fine too!)
