# NEO-GO client
|
|
|
|
The Neo-Go client is used to run node, create/compile/deploy/invoke/debug smart contracts, run vm and operate with the wallet.
|
|
|
|
## Running node
|
|
|
|
To start Neo Go node locally it's required to run
|
|
[neo-privatenet](https://hub.docker.com/r/cityofzion/neo-privatenet/) Docker image on your machine.
|
|
|
|
To run node you can use
|
|
```
|
|
make run
|
|
```
|
|
|
|
or run the binary directly:
|
|
|
|
```
|
|
./bin/neo-go node
|
|
```
|
|
|
|
By default the node will run on the `private network`, to change this use additional network flag:
|
|
|
|
```
|
|
./bin/neo-go node --mainnet
|
|
```
|
|
|
|
#### Available network flags
|
|
- `--mainnet, -m`
|
|
- `--privnet, -p`
|
|
- `--testnet, -t`
|
|
|
|
#### Configuration path
|
|
|
|
If you want to use some specific configuration path you have to use `--config-path` flag
|
|
|
|
`./bin/neo-go node --config-path /user/yourConfigPath`
|
|
|
|
## Configuration
|
|
|
|
All config files are located in `./config` and they are differentiated according to the network type:
|
|
- `protocol.mainnet.yml` belongs to `--mainnet` network mode
|
|
- `protocol.privnet.yml` belongs to `--privnet` network mode and used be default
|
|
- `protocol.testnet.yml` belongs to `--testnet` network mode
|
|
- `protocol.unit_testnet.yml` used by unit tests
|
|
|
|
Those files are automatically loaded, corresponding the provided `netmode` flag.
|
|
Example of such configuration:
|
|
```yaml

|
|
#### Node debug mode
|
|
|
|
There is a debug mode available by additional flag: `--debug, -d`
|
|
|
|
## Smart contract create/compile/deploy/invoke/debug
|
|
|
|
### Create
|
|
|
|
In order to create new smart contract:
|
|
`./bin/neo-go contract init -n TestContract`
|
|
|
|
where
|
|
`init` used to initialize new contract and `--name, -n` - to specify contract name.
|
|
|
|
It will run wizard with a few questions:
|
|
```
|
|
Author: TestAuthor
|
|
Email: test@gmail.com
|
|
Version: 1
|
|
Project name: Test
|
|
Description: desc
|
|
Successfully initialized smart contract [TestContract]
|
|
```
|
|
|
|
After that you will have a package with `TestContract` name and it will include
|
|
- `main.go` smart contract file
|
|
- `neo-go.yml` project section containing information about the contact
|
|
|
|
In case you don't want to provide details use `--skip-details, -skip`.
|
|
|
|
### Compile
|
|
|
|
```
|
|
./bin/neo-go contract compile -i mycontract.go
|
|
```
|
|
|
|
By default the output filename will be the name of your `.go` file with the `.nef` extension, the file will be located
|
|
in the same directory where you called the command from. If you want another location for your compiled contract:
|
|
|
|
```
|
|
./bin/neo-go contract compile -i mycontract.go --out /Users/foo/bar/contract.nef
|
|
```
|
|
|
|
### Deploy
|
|
//Not implemented yet
|
|
|
|
### Invoke
|
|
//Implemented in test mode. It means that it won't affect the blockchain
|
|
|
|
```
|
|
./bin/neo-go contract testinvoke -i mycontract.nef
|
|
```
|
|
|
|
### Debug
|
|
You can dump the opcodes generated by the compiler with the following command:
|
|
|
|
```
|
|
./bin/neo-go contract inspect -i mycontract.go
|
|
```
|
|
|
|
This will result in something like this:
|
|
|
|
```
|
|
INDEX OPCODE DESC
|
|
0 0x54 PUSH4
|
|
1 0xc5 NEWARRAY

|
|

|

|
|
```
|
|
|
|
In depth documentation about the **neo-go** compiler and smart contract examples can be found inside
|
|
the [compiler package](pkg/compiler).
|
|
|
|
## VM run
|
|
To run VM use
|
|
|
|
```
|
|
./bin/neo-go vm
|
|
```
|
|
|
|
For the detailed help use `help` in VM console.
|
|
There is a small subset of commands:
|
|
|
|
- `loadgo` -- loads smart contract `NEO-GO-VM > loadgo TestContract/main.go`
|
|
- `ops` -- show the opcodes of currently loaded contract
|
|
- `run` -- executes currently loaded contract
|
|
|
|
## Wallet operations
|
|
|
|
- `./bin/neo-go wallet init -w newWallet` to create new wallet in the path `newWallet`
|
|
- `./bin/neo-go wallet dump -w newWallet` to open created wallet in the path `newWallet`
|
|
- `./bin/neo-go wallet init -w newWallet -a` to create new account
|
