iavlplus

This is a Swift iAVL+ Tree protocols and reference implementations to build Tendermint consensus based blockchain applications.

iAVL+ trees are the core structure to provide state to a CosmosSwift blockchain app.

This is work in progress.

We are using the Go Tendermint codebase as a starting point, and implementing the Swift code in a Swifty way.

Swift version: 5.2.x

Installation

Requires Swift 5.2.x, on MacOS or a variant of Linux with the Swift 5.2.x toolchain installed.

git clone https://github.com/CosmosSwift/swift-iavlplus.git
cd swift-iavlplus
swift build

In your Package.swift file, add the repository as a dependency as such:

import PackageDescription

let package = Package(
    name: "MyiAVLPlusApp",
    products: [
        .executable(name: "MyiAVLPlusApp", targets: ["MyiAVLPlusApp"]),
    ],
    dependencies: [
        .package(url: "https://github.com/cosmosswift/swift-iavlplus.git", from: "0.1.0"),
    ],
    targets: [
        .target(name: "MyiAVLPlusApp", dependencies: ["iAVLPlus"]),
    ]
)

Getting Started

0. import IAVLPlus

1. Compile and run

Development

Development Setup:

• $ brew install swiftformat swiftlint pre-commit
• $ pre-commit install

Pre-Commit

• Pre-commit sets up some hooks that are run before ever commit (nomen est omen)
• To run it manually it can be used as pre-commit run [somefile] or pre-commit run --all-files
• To overrule pre-commit simply add -n to your commit command e.g. git commit -m "Fancy commit message" -n

Code, Test, Build, Release:

We make use of GitHub Actions to automate the big junks.

• Coding should preferable happen in feature branches, point to master
• On feature branches a basic CI pipeline runs to ensure the basics are ok before merging
