Typescript with LLVM backend.
First of all, you need install LLVM, See https://llvm.org/docs/GettingStarted.html. But if you are using Ubuntu or other distributions, using the built-in package management tool is a more convenient option like:
$ apt install -y llvm
Then install minits:
$ git clone https://github.com/cryptape/minits
$ npm install
$ npm run build
Filename: main.ts
function main(): number {
console.log("Hello World!");
return 0;
}Save the file and open your terminal:
$ node build/main/index.js build main.ts -o main.ll
$ clang main.ll -o main
$ ./main
minits is a completely static language, similar to clang or rust, function main() is the entry point to every executable minits program. It receives(optional) 2 parameters argc: number and argv: string[], and returns the exit code. So you can also write it as function main(argc: number, argv: string[]): number.
We suggest you read the source code under ./examples. Let's hava a look at ./examples/brainfuck.ts. Brainfuck is an esoteric programming language created in 1993 by Urban Müller, and is notable for its extreme minimalism. We wrote a brainfuck interpreter by minits. Compile this interpreter by
$ node build/main/index.js build examples/brainfuck.ts -o brainfuck.ll
$ clang brainfuck.ll -o brainfuck
And then execute a piece of code that generates Sierpinski Triangle:
$ ./brainfuck ">++++[<++++++++>-]>++++++++[>++++<-]>>++>>>+>>>+<<<<<<<<<<[-[->+<]>[-<+>>>.<<]>>>[[->++++++++[>++++<-]>.<<[->+<]+>[->++++++++++<<+>]>.[-]>]]+<<<[-[->+<]+>[-<+>>>-[->+<]++>[-<->]<<<]<<<<]++++++++++.+++.[-]<]+++++"
Most ts syntax is available at now, but there is still a lot of work to be done.
We plan to implement the following syntax:
- Primitive Types
- number(support signed 64):
0x10,12 - boolean:
true,false - string:
"Hello" - void
- null
-
* undefined - enum:
enum { a = 1, b, c }
- number(support signed 64):
- Object
- Array
- Tuple
- Assignment:
let a: number = 1;,let a: number[] = [1, 2, 3] - Parentheses
- Function Expressions
- Arrow Functions
- * Class Expressions
- Function Calls
-
++/-- -
+/-/~ -
! - *
typeof - +: number + number, string + string, eg.
-
*,/,%,–,<<,>>,>>>,&,^, and|operators -
<,>,<=,>=,==,!=,===, and!==operators - *

&&and|| - The Conditional Operator:
