Swift CodeArtSyntax Package

Welcome to CodeArtSyntax - lightweight and flexible Swift syntax highlighter. It can be used to generate Swift code for your project (in the future it will support multiple programming languages), to turn a string of Swift code into a fully syntax highlighted image, or to build custom developer tools.

Usage

CodeArtSyntax can be used either as a library in your own Swift Package Manager-powered tool or script

📦 As a package

To include CodeArtSyntax in your own script or Swift package, add it as a dependency and use the CodeArtSyntaxView class combined with your output format of choice to highlight a string of code:

import UIKit

protocol SyntaxBase {
    var syntaxTheme: SyntaxTheme { get set }
    var syntax: Syntax { get }
    func format(text: String, fontSize: CGFloat) -> NSMutableAttributedString
}

// Supported Public Syntaxes Enum
public enum Syntax {
    case SWIFT
}

// Highlight Types
enum HighlightType {
    case number
    case comment
    case keyword
    case string
    case punctuation
    case klass // or struct
    case constant
}

class HighlightSpan {
    private static func textStyle(syntaxTheme: SyntaxTheme, type: HighlightType) -> TextStyle {
        switch type {
        case .number:
            return syntaxTheme.numberStyle
        case .comment:
            return syntaxTheme.commentStyle
        case .keyword:
            return syntaxTheme.keywordStyle
        case .string:
            return syntaxTheme.stringStyle
        case .punctuation:
            return syntaxTheme.punctuationStyle
        case .klass:
            return syntaxTheme.classStyle
        case .constant:
            return syntaxTheme.constantStyle
        }
    }
    
     static func getSyntax(syntax: Syntax, theme: SyntaxTheme) -> SyntaxBase {
        switch syntax {
        case .SWIFT:
            return SwiftSyntaxHighlighter(syntaxTheme: theme)
        }
    }
}

CodeArtSyntax ships with one built-in output format - NSAttributedString

Installation

CodeArtSyntax is distributed as a Swift package, making it easy to install for use in scripts, developer tools, server-side applications

CodeArtSyntax required minimum IOS 16 version which can be compatible for the project going on

Before you begin, make sure that you have a Swift 5.2-compatible toolchain installed (for example Xcode 11.5 or later if you’re on a Mac).

📦 As a package

To install CodeArtSyntax for use in a Swift Package Manager-powered tool or server-side application, add CodeArtSyntax as a dependency to your Package.swift file. For more information, please see the Swift Package Manager documentation.

.package(url: "https://github.com/iamnijat/CodeArtSyntax", from: "0.1.0")

📦 As a configuration

To configure CodeArtSyntax in your project you can easily copy-paste this code block to your workspace:

 CodeArtSyntaxView(code: code, syntax: .SWIFT, withLinesCount: true, syntaxTheme: SyntaxTheme.vsCodeDark(), fontSize: 13)

Contributions and support

CodeArtSyntax is developed completely in the open, and your contributions are more than welcome. It’s still a very new project, so I’m sure there are bugs to be found and improvements to be made - and hopefully we can work on those together as a community.

This project does not come with GitHub Issues-based support, and users are instead encouraged to become active participants in its continued development — by fixing any bugs that they encounter, or by improving the documentation wherever it’s found to be lacking.

Hope you enjoy using CodeArtSyntax!

I had a lot of fun building CodeArtSyntax, and I’m looking forward to continue working on it in the open together with you! I hope you’ll like it and that you’ll find it useful. Let me know what you think on Twitter 😊
