Testing SourceKit

July 2017

Some spells for testing SourceKit.

sourcekitd-test

Setup:

alias st=/Users/johnf/project/swift-source/build/jfdev/swift-macosx-x86_64/bin/sourcekitd-test

Simple tests against files, no imports:

st -req=structure ${PWD}/test.swift -- ${PWD}/test.swift`

Add Foundation etc:

st -req=structure -using-swift-args ${PWD}/test.swift -- \
        ${PWD}/test.swift \
        -sdk `xcrun --sdk macosx --show-sdk-path`

CursorInfo:

st -req=cursor -offset=XXX -print-response-as-json \
        ${PWD}/test.swift -- ${PWD}/test.swift

Setup:

alias si=/Users/johnf/project/swift-source/build/jfdev/swift-macosx-x86_64/bin/swift-ide-test

Structure query:

si -structure -source-filename test.swift

To get some idea of what Xcode is doing and how happy it feels, after switching to custom toolchain:
