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))

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` Ethereum CLI
|

* `ethtest` test tool which runs with the [tests](https://github.com/ethereum/testes) suit:
|
||||
* `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.
|
||||
* `rlpdump` converts a rlp stream to `interface{}`.
|
||||
* `peerserver` simple P2P (noi-ethereum) peer server.
|
||||
* `disasm` disassembles EVM code: `echo "6001" | disasm`

General command line options

Command line options
|
||||
============================
|
||||
|
||||
Both `mist` and `ethereum` can be configured via command line options, environment variables and config files.
|
||||
|
||||
To get the options available:
|
||||
|
||||
```
|
||||
== Shared between ethereum and Mist ==
|
||||
|
||||
= Settings
|
||||
-id Set the custom identifier of the client (shows up on other clients)
|
||||
-port Port on which the server will accept incomming connections
|
||||
-upnp Enable UPnP
|
||||
-maxpeer Desired amount of peers
|
||||
-rpc Start JSON RPC
|
||||
-dir Data directory used to store configs and databases
|
||||
|
||||
= Utility
|
||||
-h This
|
||||
-import Import a private key
|
||||
-genaddr Generates a new address and private key (destructive action)
|
||||
-dump Dump a specific state of a block to stdout given the -number or -hash
|
||||
-difftool Supress all output and prints VM output to stdout
|
||||
-diff vm=only vm output, all=all output including state storage
|
||||
|
||||
Ethereum only
|
||||
ethereum [options] [filename]
|
||||
-js Start the JavaScript REPL
|
||||
filename Load the given file and interpret as JavaScript
|
||||
-m Start mining blocks
|
||||
|
||||
== Mist only ==
|
||||
|
||||
-asset_path absolute path to GUI assets directory
|
||||
ethereum -help
|
||||
```
|
||||

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 should be manually verified then commited.

To make life easier try [git flow](http://nvie.com/posts/a-successful-git-branching-model/) it sets

|
||||
|
||||
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!)
|
||||
