When trying to compile, I get a String error

[felix91gr]

I'm on Linux, under Swift 4.1

This is what I ran:

felix@felix-X550LD ~/D/P/A/beak> swift build
Compile Swift Module 'BeakCore' (15 sources)
/home/felix/Documents/Programming/AwesomeSystemSwift/beak/Sources/BeakCore/SourceKit.swift:86:54: error: value of type 'String' has no member 'substringWithByteRange'
        let substring = range(for: source).flatMap { contents.substringWithByteRange(start: Int($0.offset), length: Int($0.length)) }
                                                     ^~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~
error: terminated(1): /home/felix/Documents/Programming/Binaries/swift/swift-4.1-snapshot/usr/bin/swift-build-tool -f /home/felix/Documents/Programming/AwesomeSystemSwift/beak/.build/debug.yaml main output:
    

This line's the one causing the error. Maybe the library hasn't been updated to Swift 4.1?

Anyway. Thanks for your help, and I hope you have a good day :)

Hi @felix91gr
Did it work before in Swift 4.0 on Linux?
It works on Swift 4.1 on macOS. Beak hasn't actually been tested on Linux, but it's something that can be looked at

Beak hasn't actually been tested on Linux, but it's something that can be looked at

Ohh! You can try to do it in a sandbox with Docker. Benedikt Terhechte did that for SourceKittenDaemon so that Mac users can run the tests locally for Linux as well. The setup is super easy :)

Did it work before in Swift 4.0 on Linux?

Haven't tried. I'm gonna see if I still have the 4.0 toolchain somewhere. If not, I'll download another one and test it. Maybe the 4.0 -> 4.1 transition broke it somehow.

[felix91gr]

Yup, it doesn't work under 4.0 either. I'm gonna investigate further.

Thanks @felix91gr

[felix91gr]

Hmm. Is substringWithByteRange a property provided by Foundation? Since Foundation is incomplete on Linux, maybe therein lies the problem 🤔

[felix91gr]

It's provided by SourceKittenFramework! Jesus, I never would've guessed. Of course I'd have a hard time looking it up in Apple's documentation 😆

Now then... why does the compiler fail to see it in Linux? 🤔 this is gonna need some digging around.

Any updates on this @felix91gr?

[felix91gr]

No! I'm sorry, I've been away at other projects and studying. I will put it on my to-do list to debug this someday :) (maybe in July, when I have winter holidays)

In the meantime, you can try to run the tests in Linux with a more polished docker utility: this one which is new and really nice.

Again, sorry for disappearing. I must've closed the tab I had Beak on, and then it slipped through my fingers 😅

[yonaskolb]

All good! Got swift-docker up and running now, it's great!

Fixed here #33
