Contribution

If you would like to contribute to Ethereum Go, please fork, fix, commit and send a pull request to the main repository. Commits which do not comply with the coding standards explained below will be ignored. If you send a pull request, make sure that you commit to the develop branch and that you do not merge to master. Commits that are directly based off of the master branch instead of the develop branch will be ignored.

To make this process simpler try following the git flow branching model, as it sets this process up and streamlines work flow.

Coding standards

Code should be formatted according to the Go Formatting Style.

Unless struct fields are supposed to be directly accessible, provide getters and hide the fields through Go's exporting facility.

Make comments in your code meaningful and only use them when necessary. Describe in detail what your code is trying to achieve. For example, this would be redundant and unnecessary commenting:

wrong

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

Everyone reading the source code should know what this code snippet was meant to achieve, and so those are not meaningful comments.

While this project is constantly tested and run, code tests should be written regardless. There is not time to evaluate every person's code specifically, so it is expected of you to write tests for the code so that it does not have to be tested manually. In fact, contributing by simply writing tests is perfectly fine!
