Re: [swift-users] Using Swift for interpreted shell scripts?

[Dominik Hauser via swift-users]

I write my scripts in a Playground to get autocompletion and instant feedback. 
Kind of works but sometimes I wish Playgrounds would start faster with running. 
And sometimes they stop working and I have to restart Xcode.

Probably not. You can just call `swift` and it will shim through to the same 
thing as `xcrun swift`.

IIRC, 10.9 didn't have the `swift` shim, but every OS X release since then has.

Thank you, that looks very promising.

I didn’t realize the list was set to “reply off list” so a message I thought I 
posted didn’t go through. Rather than repost it…

Interesting. I was just messing around with

#!/usr/bin/swift

And making some (albeit slow) progress.

Is there a reason to use xcrun instead of calling swift directly?

[swift-users] Using Swift for interpreted shell scripts?

[@lbutlr via swift-users]

Are there any resources on using swift for shell scripting?

I’m interested in trying my hand at Swift by converting existing bash scripts 
into swift since bash is mostly what I am writing currently, so I figure this 
will at least get me started with syntax and such.

I've given up on it. I find it far easier to just write a command-line app with 
Xcode's source support -- E

Re: [swift-users] Using Swift for interpreted shell scripts?

[Jens Alfke via swift-users]

Swift doesn’t seem like a good fit for the kinds of tasks people write 
shell-scripts for. It’s a system/app programming language, like C/C++. 
Scripting languages have extremely dynamic typing, super-high-level APIs, and 
no separate compile/link stage.

There’s no reason you couldn’t convert some shellscripts as an exercise to 
learn Swift, but I don’t think you’ll find many resources out there.
