Ruby SDK for CKB
The ckb-sdk-ruby is still under development and NOT production ready. You should get familiar with CKB transaction structure and RPC before using it.
## WARNING
Module Indexer has been removed from [ckb_v0.40.0](https://github.com/nervosnetwork/ckb/releases/tag/v0.40.0): Please use [ckb-indexer](https://github.com/nervosnetwork/ckb-indexer) as an alternate solution.
The following RPCs hash been removed from [ckb_v0.40.0](https://github.com/nervosnetwork/ckb/releases/tag/v0.40.0):
* `get_live_cells_by_lock_hash`
* `get_transactions_by_lock_hash`
* `index_lock_hash`
* `deindex_lock_hash`
* `get_lock_hash_index_states`
* `get_capacity_by_lock_hash`
Since [ckb_v0.36.0](https://github.com/nervosnetwork/ckb/releases/tag/v0.36.0) SDK use [ckb-indexer](https://github.com/nervosnetwork/ckb-indexer) to collect cells, please see [Usage](#usage) for examples.
## Prerequisites
Require Ruby 2.4 and above.
### Ubuntu
```bash
sudo apt install libsodium-dev
```
This SDK depends on the [rbsecp256k1](https://github.com/etscrivner/rbsecp256k1) gem. You need to install libsecp256k1. Follow [this](https://github.com/etscrivner/rbsecp256k1#requirements) to do so.
### macOS
```bash
brew tap nervosnetwork/tap
brew install libsodium libsecp256k1
```
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'ckb-sdk-ruby', github: 'nervosnetwork/ckb-sdk-ruby', require: 'ckb'
```
And then execute:
$ bundle install
If you just want to use it in a console:
```
git clone https://github.com/nervosnetwork/ckb-sdk-ruby.git
cd ckb-sdk-ruby
bundle install
bundle exec bin/console
```
## Usage
RPC interface returns parsed `JSON` object
```ruby
rpc = CKB::RPC.new
# using RPC `get_tip_header`, it will return a Hash
rpc.get_tip_header
```
API interface returns `Types` instead of `Hash`
```ruby
api = CKB::API.new
# it will return a CKB::Types::BlockHeader
api.get_tip_header
```
Send capacity
```ruby
# create api first
api = CKB::API.new
# create ckb-indexer api
indexer_api = CKB::Indexer::API.new
# create two wallet object
bob = CKB::Wallet.from_hex(api, "0xe79f3207ea4980b7fed79956d5934249ceac4751a4fae01a0f7c4a96884bc4e3", indexer_api: indexer_api)
alice = CKB::Wallet.from_hex(api, "0x76e853efa8245389e33f6fe49dcbd359eb56be2f6c3594e12521d2a806d32156", indexer_api: indexer_api)
# bob send 1000 bytes to alice
tx_hash = bob.send_capacity(alice.address, 1000 * 10**8, fee: 1000)
# loop up the transaction by tx_hash
api.get_transaction(tx_hash)
```
Provide wallet with a public key
```ruby
api = CKB::API.new
indexer_api = CKB::Indexer::API.new
bob = CKB::Wallet.new(api, "0x024a501efd328e062c8675f2365970728c859c592beeefd6be8ead3d901330bc01", indexer_api: indexer_api)
alice = CKB::Wallet.new(api, "0x0257623ec521657a27204c5590384cd59d9267c06d75ab308070be692251b67c57", indexer_api: indexer_api)
bob_key = "0xe79f3207ea4980b7fed79956d5934249ceac4751a4fae01a0f7c4a96884bc4e3"
tx_hash = bob.send_capacity(alice.address, 1000 * 10**8, key: bob_key)
```
## Run Tests
```bash
BOB_PRIVATE_KEY="0xe79f3207ea4980b7fed79956d5934249ceac4751a4fae01a0f7c4a96884bc4e3" rake spec
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`.
