This project is pretty much abandoned. It's too much work to keep up with the changing LLVM APIs
Tranquil is a programming language built on top of LLVM & the Objective-C Runtime.
It aims to provide a more expressive & easy to use way to write Mac and iOS Apps.
Its features include:
- Compatibility with C/ObjC headers, meaning that there is no need to create special bindings for C APIs.
- Automatic memory management.
- Line by line debugging. (Using LLDB or GDB) — still under development, but breaking on, and stepping over source lines is supported
- Dynamic Typing.
- Language level concurrency support.
- String interpolation.
- Multiple assignment.
- Message cascading.
- Unlimited number range.
- Unicode through&through (変数=123 works fine)
- Good performance, even at this extremely early stage.
- And more..
However, Tranquil is still extremely experimental and you shouldn't use it for anything other than exploration and learning.
The simplest way of getting started is to use the binary installer. Everything will be placed into /usr/local/tranquil (Requires Xcode 5.1 to be installed)
If you wish to contribute, you can use the install script instead which checks out the latest source and sets up the development environment.
> curl -fsSkL https://raw.github.com/fjolnir/Tranquil/master/Tools/install.sh | /bin/zsh
> /usr/local/tranquil/bin/tqrepl
Note: OS X ≥ 10.7 or iOS ≥ 5 is required to run compiled tranquil programs. 10.9 is required to compile.
To learn more about Tranquil you should read the specification and check out the tests.
You can also talk to me directly by visiting #tranquil on irc.freenode.net.
And here're a couple of examples:
mandelbrot = { x, y, bailout=16, maxIter=1000 |
cr, ci = y-0.5, x
zi, zr = 0
maxIter times: {
temp = zr*zi
zr2, zi2 = zr^2, zi^2
zr = zr2 - zi2 + cr
zi = 2*temp + ci
^^no if zi2 + zr2 > bailout
}
^yes
}
(-1 to: 1 withStep: 1/40) each: { y |
(-1 to: 1 withStep: 1/40) each: { x |
(mandelbrot(x, y) ? #● ! #◦) printWithoutNl
}
#"" print
}
alternatives = ["Objective-C", "Ruby", "Nu", "Perl", "Python"]
alternatives each: `alternative | "Tranquil is nicer than «alternative»" print`
"Or so I hope at least." print
sum = (0 to: 1000000) reduce: `obj, accum=0 | obj+accum`
a = async foo()
b = bar()
whenFinished {
"a is «a» and b is: «b»" print
}
var = Character new setName: "Deckard"; setOccupation: "Blade Runner"; self
a, b = b, a \ Swap b&a
a = {
b = {
^^123
}
b()
^321
}
a() print \ This prints '123'
fib = `n | n > 1 ? fib(n-1) + fib(n-2) ! n`
fib(10) print
Make a database query (Using DatabaseKit)
import "DatabaseKit"
db = DB withURL: "sqlite://data/database.sqlite"
query = db[#aTable] select: #field; where: { #anotherField => aValue }
val = query[#field]
\ We can write that more concisely as:
val = table[{ #anotherField => aValue }][#field]
Create a Web Server (Using HTTPKit)
import "HTTPKit"
HTTP new handleGet: "/"
with: `connection| "Hello World!"`;
listenOnPort: 8080
onError: `"Unable to start server" print`
"Foobar starts with foo." print if /foo[a-z]+/i matches: "Foobar"
import "GLUT" \ This simply reads in your GLUT.h header. No bindings are required.
