|
|
## Dev Environment Setup
|
|
|
|
```bash
|
|
export GOPATH=$HOME/<path_of_your_choice>
|
|
|
|
mkdir -p $HOME/<path_of_your_choice>/src/github.com/harmony-one
|
|
|
|
cd $HOME/<path_of_your_choice>/src/github.com/harmony-one
|
|
|
|
git clone git@github.com:harmony-one/harmony.git
|
|
|
|
cd harmony
|
|
|
|
go get ./...
|
|
|
|
git submodule update --init --recursive
|
|
|
|
```
|
|
|
|
## Build
|
|
|
|
Harmony server / main node:
|
|
```
|
|
go build -o bin/harmony cmd/harmony.go
|
|
```
|
|
|
|
Beacon node:
|
|
```
|
|
go build -o bin/beacon cmd/beaconchain/main.go
|
|
```
|
|
|
|
Wallet:
|
|
```
|
|
go build -o bin/wallet cmd/client/wallet/main.go
|
|
```
|
|
|
|
Tx Generator:
|
|
```
|
|
go build -o bin/txgen cmd/client/txgen/main.go
|
|
```
|
|
|
|
You can also run the script `./scripts/go_executable_build.sh` to build all the executables.
|
|
|
|
Some of our scripts require bash 4.x support, please [install bash 4.x](http://tldrdevnotes.com/bash-upgrade-3-4-macos) on MacOS X.
|
|
|
|
## Usage
|
|
You may build the src/harmony.go locally and run local test.
|
|
|
|
### Running local test
|
|
The deploy.sh script creates a local environment of Harmony blockchain devnet based on the configuration file.
|
|
The configuration file configures number of nodes and their IP/Port.
|
|
The script starts one local beacon chain node, the blockchain nodes, and run a transactional generator program which generates and sends simulated transactions to the local blockchain.
|
|
|
|
```bash
|
|
./test/deploy.sh ./test/configs/local_config1.txt
|
|
```
|
|
|
|
## Testing
|
|
|
|
Make sure you use the following command and make sure everything passed before submitting your code.
|
|
|
|
```bash
|
|
./test/test_before_submit.sh
|
|
```
