SwiftShell

A Swift module for shell scripting.

Installation

In the Terminal, go to where you want to download SwiftShell.
Run

git clone https://github.com/kareman/SwiftShell.git 
cd SwiftShell

Copy/link Div/swiftshell to your bin folder or anywhere in your PATH.
To install the framework, either:
- run xcodebuild install from the project's root folder. This will install the SwiftShell framework in ~/Library/Frameworks.
- or run xcodebuild and copy the resulting framework from the build folder to your library folder of choice. If that is not "~/Library/Frameworks", "/Library/Frameworks" or a folder mentioned in the $DYLD_FRAMEWORK_PATH environment variable then you need to add your folder to $DYLD_FRAMEWORK_PATH.

Examples

Print standard input with line numbers

#!/usr/bin/env swiftshell

import SwiftShell

var i = 1
for line in standardinput.lines() {
	print("line \(i++): ")
	println(line)
}

Launch with e.g. ls | print_linenumbers.swift

List all executables in PATH

#!/usr/bin/env swiftshell

import SwiftShell

let directories = environment["PATH"]!.split(":")

for directory in directories {
	run("find \"\(directory)\" -type f -perm +ugo+x -print") |> standardoutput
}

Pipe several commands together

#!/usr/bin/env swiftshell

import SwiftShell

run("echo this is streamed") |> run("wc -w") |> standardoutput
