Swift REPL Madness
(Thanks to @Pitometsu I was able to update this for Swift 4)
In order to use a Swift package in the REPL you need to add a dynamic library product to
Package.swift So, for example, if you have a package named
Sample, you need to add the following to the package manifest:
products: [ . . . .library( name: "Sample", type: .dynamic, targets: ["Sample"]), . . . ],
Now build as usual:
Then to be able to use it from the REPL:
swift -I .build/debug -L .build/debug -lSample
At this point, the REPL will start up and from its prompt, you can
import the package and use it's public declarations:
Welcome to Apple Swift version 4.0.2 (swiftlang-900.0.69.1.... 1> import Sample 2> // do something with the Sample package...
See it in action
The code in this repo includes a sample package named
swiftreplmadness which defines one public data type,
simplestruct. You can use the included
Makefile to build the package and start up the REPL. Simply change to the project's root directory and type
