Build
=====
Mist (GUI):
`go get github.com/ethereum/go-ethereum/cmd/mist`
Ethereum (CLI):
`go get github.com/ethereum/go-ethereum/cmd/ethereum`
As of POC-8, go-ethereum uses [Godep](https://github.com/tools/godep) to manage dependencies. Assuming you have [your environment all set up](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go)), switch to the go-ethereum repository root folder, and build/install the executable you need:
Mist (GUI):
```
godep go build -v ./cmd/mist
```
Ethereum (CLI):
```
godep go build -v ./cmd/ethereum
```
Instead of `build`, you can use `install` which will also install the resulting binary.
For prerequisites and detailed build instructions please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
If you intend to develop on go-ethereum, check the [Developers' Guide](https://github.com/ethereum/go-ethereum/wiki/Developers'-Guide)
Automated (dev) builds
======================
* [[Docker](https://registry.hub.docker.com/u/ethereum/client-go/)]
* [[OS X](http://build.ethdev.com/builds/OSX%20Go%20develop%20branch/Mist-OSX-latest.dmg)]
* [Windows] Coming soon™
* [Linux] Coming soon™
Executables
===========
Go Ethereum comes with several wrappers/executables found in
[the `cmd` directory](https://github.com/ethereum/go-ethereum/tree/develop/cmd):
* `mist` Official Ethereum Browser (ethereum GUI client)
* `ethereum` Ethereum CLI (ethereum command line interface client)
* `bootnode` runs a bootstrap node for the Discovery Protocol
* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suite:
`cat file | ethtest`.
* `evm` is a generic Ethereum Virtual Machine: `evm -code 60ff60ff -gas
10000 -price 0 -dump`. See `-h` for a detailed description.
* `disasm` disassembles EVM code: `echo "6001" | disasm`
* `rlpdump` converts a rlp stream to `interface{}`.
Command line options
============================
Both `mist` and `ethereum` can be configured via command line options, environment variables and config files.
To get the options available:
```
ethereum -help
```
For further details on options, see the [wiki](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)
Contribution
============
If you'd like to contribute to go-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.
For dependency management, we use [godep](https://github.com/tools/godep). After installing with `go get github.com/tools/godep`, run `godep restore` to ensure that changes to other repositories do not break the build. To update a dependency version (for example, to include a new upstream fix), run `go get -u <foo/bar>` then `godep update <foo/...>`. To track a new dependency, add it to the project as normal than run `godep save ./...`. Changes to the [Godeps folder](https://github.com/ethereum/go-ethereum/tree/develop/Godeps): should be manually verified then commited.
To make life easier try [git flow](http://nvie.com/posts/a-successful-git-branching-model/) it sets this all up and streamlines your work flow.
See [Developers' Guide](https://github.com/ethereum/go-ethereum/wiki/Developers'-Guide)
Coding standards
================
Sources should be formatted according to the [Go Formatting
Style](http://golang.org/doc/effective_go.html#formatting).
Unless structs fields are supposed to be directly accesible, provide
Getters and hide the fields through Go's exporting facility.
When you comment put meaningful comments. Describe in detail what you
want to achieve.
*wrong*
```go
// 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!)
