## Writing smart contracts in Go
|
||||
Golang's development is been moved to a separate repository which you can find here [neo-storm](https://github.com/CityOfZion/neo-storm)
|
||||
In depth documentation about the **neo-go** compiler and smart contract examples can be found inside the [compiler package](https://github.com/CityOfZion/neo-go/tree/master/pkg/vm/compiler).
|
||||
|
||||
### Compile a smart contract
|
||||
|
||||
```
|
||||
./bin/neo-go contract compile -i mycontract.go
|
||||
```
|
||||
|
||||
By default the filename will be the name of your `.go` file with the `.avm` 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.avm
|
||||
```
|
||||
|
||||
### Debugging your smart contract
|
||||
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:
|
||||
|
||||
```
|
||||
