SourceKitten

An adorable little framework and command line tool for interacting with SourceKit.

SourceKitten links and communicates with sourcekitd.framework to parse the Swift AST, extract comment docs for Swift or Objective-C projects, get syntax data for a Swift file and lots more!

SwiftPM

Installation

Building SourceKitten requires Xcode 11 or later or a Swift 5.1 toolchain or later with the Swift Package Manager.

SourceKitten typically supports previous versions of SourceKit.

Homebrew

Run brew install sourcekitten.

Swift Package Manager

Run swift build in the root directory of this project.

Xcode (via Make)

Run make install in the root directory of this project.

Package

Download and open SourceKitten.pkg from the releases tab.

Command Line Usage

Once SourceKitten is installed, you may use it from the command line.

$ sourcekitten help

How is SourceKit resolved?

SourceKitten searches for SourceKit in the following order:

  • $XCODE_DEFAULT_TOOLCHAIN_OVERRIDE
  • $TOOLCHAIN_DIR
  • xcrun -find swift
  • /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain
  • /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain
  • ~/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain
  • ~/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain

On Linux, SourceKit is expected to be located in /usr/lib/libsourcekitdInProc.so or specified by the LINUX_SOURCEKIT_LIB_PATH environment variable.

Complete

Running sourcekitten complete --file file.swift --offset 123 or sourcekitten complete --text "0." --offset 2 will print out code completion options for the offset in the file/text provided:

[{
  "descriptionKey" : "advancedBy(n: Distance)",
  "associatedUSRs" : "s:FSi10advancedByFSiFSiSi s:FPSs21RandomAccessIndexType10advancedByuRq_S__Fq_Fqq_Ss16ForwardIndexType8Distanceq_ s:FPSs16ForwardIndexType10advancedByuRq_S__Fq_Fqq_S_8Distanceq_ s:FPSs10Strideable10advancedByuRq_S__Fq_Fqq_S_6Strideq_ s:FPSs11_Strideable10advancedByuRq_S__Fq_Fqq_S_6Strideq_",
  "kind" : "source.lang.swift.decl.function.method.instance",
  "sourcetext" : "advancedBy(<#T##n: Distance##Distance#>)",
  "context" : "source.codecompletion.context.thisclass",
  "typeName" : "Int",
  "moduleName" : "Swift",
  "name" : "advancedBy(n: Distance)"
},
{
  "descriptionKey" : "advancedBy(n: Self.Distance, limit: Self)",
  "associatedUSRs" : "s:FeRq_Ss21RandomAccessIndexType_SsS_10advancedByuRq_S__Fq_FTqq_Ss16ForwardIndexType8Distance5limitq__q_",
  "kind" : "source.lang.swift.decl.function.method.instance",
  "sourcetext" : "advancedBy(<#T##n: Self.Distance##Self.Distance#>, limit: <#T##Self#>)",
  "context" : "source.codecompletion.context.superclass",
  "typeName" : "Self",
  "moduleName" : "Swift",
  "name" : "advancedBy(n: Self.Distance, limit: Self)"
},
...
]

To use the iOS SDK, pass -sdk and -target arguments preceded by --:

sourcekitten complete --text "import UIKit ; UIColor." --offset 22 -- -target arm64-apple-ios9.0 -sdk /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk

Doc

Running sourcekitten doc will pass all arguments after what is parsed to xcodebuild (or directly to the compiler, SourceKit/clang, in the --single-file mode).

Example usage

  1. sourcekitten doc -- -workspace SourceKitten.xcworkspace -scheme SourceKittenFramework
  2. sourcekitten doc --single-file file.swift -- -j4 file.swift
  3. sourcekitten doc --module-name Alamofire -- -project Alamofire.xcodeproj
  4. sourcekitten doc -- -workspace Haneke.xcworkspace -scheme Haneke
  5. sourcekitten doc --objc Realm/Realm.h -- -x objective-c -isysroot $(xcrun --show-sdk-path) -I $(pwd)

Structure

Running sourcekitten structure --file file.swift or sourcekitten structure --text "struct A { func b() {} }" will return a JSON array of structure information:

{
  "key.substructure" : [
    {
      "key.kind" : "source.lang.swift.decl.struct",
      "key.offset" : 0,
      "key.nameoffset" : 7,
      "key.namelength" : 1,
      "key.bodyoffset" : 10,
      "key.bodylength" : 13,
      "key.length" : 24,
      "key.substructure" : [
        {
          "key.kind" : "source.lang.swift.decl.function.method.instance",
          "key.offset" : 11,
          "key.nameoffset" : 16,
          "key.namelength" : 3,
          "key.bodyoffset" : 21,
          "key.bodylength" : 0,
          "key.length" : 11,
          "key.substructure" : [

          ],
          "key.name" : "b()"
        }
      ],
      "key.name" : "A"
    }
  ],
  "key.offset" : 0,
  "key.diagnostic_stage" : "source.diagnostic.stage.swift.parse",
  "key.length" : 24
}

Syntax

Running sourcekitten syntax --file file.swift or sourcekitten syntax --text "import Foundation // Hello World" will return a JSON array of syntax highlighting information:

[
  {
    "offset" : 0,
    "length" : 6,
    "type" : "source.lang.swift.syntaxtype.keyword"
  },
  {
    "offset" : 7,
    "length" : 10,
    "type" : "source.lang.swift.syntaxtype.identifier"
  },
  {
    "offset" : 18,
    "length" : 14,
    "type" : "source.lang.swift.syntaxtype.comment"
  }
]

Request

Running sourcekitten request --yaml [FILE|TEXT] will execute a sourcekit request with the given yaml. For example:

key.request: source.request.cursorinfo
key.sourcefile: "/tmp/foo.swift"
key.offset: 8
key.compilerargs:
  - "/tmp/foo.swift"

SourceKittenFramework

Most of the functionality of the sourcekitten command line tool is actually encapsulated in a framework named SourceKittenFramework.

If you’re interested in using SourceKitten as part of another tool, or perhaps extending its functionality, take a look at the SourceKittenFramework source code to see if the API fits your needs.

Note: SourceKitten is written entirely in Swift, and the SourceKittenFramework API is not designed to interface with Objective-C.

Release Notes

0.31.0: Time Feline Of The Year
22 weeks ago
Breaking
  • SourceKitten now requires Swift 5.2 or higher to build.
    JP Simard

  • SourceKittenFramework can no longer be integrated as a Carthage depdendency.
    JP Simard

  • SourceKitten.xcworkspace and sourcekitten.xcproject have been completely removed. You can still use Xcode to develop SourceKitten by opening it as a Swift Package by typing xed . or xed Package.swift from your shell.
    JP Simard

  • The command line syntax has slightly changed due to migrating from the Commandant command line parsing library to swift-argument-parser. For the most part the breaking changes are all to make the syntax more unix compliant and intuitive to use. For example, commands such as sourcekitten --help or sourcekitten -h now work as expected. The help output from various commands has greatly improved as well. A few notable breaking changes:

    • doc --spm-module was removed (use --spm --module-name instead)
    • sourcekitten module_info is now sourcekitten module-info
      JP Simard
Enhancements
  • None.
