tscc

Typescript to C compiler

Support

The compiler currently supports:

• Function definitions
• Data types (string, number, null, void, undefined)
• Arrays (sort of)
• Function calls
• If
• Else
• While loops
• Static string concatenation ("hello " + "world")
• Automatically detect requirements and inject #include tags
• == - comparison
• != - comparison
• < - comparison
• > - comparison
• Null values
• Undefined values
• Classes with methods
• Classes with member variables
• console.log

Installation & Usage

To install tscc, first simply compile it:

    make

Then you can move it to /usr/local/bin:

    sudo mv ./tscc.out /usr/local/bin/tscc

Now you can use it like this:

    tscc <filename>.ts

Known issues

For loops

For loops does not work:

    for (let entry of someArray) {
        console.log(entry); // 1, "string", false
    }

Comments

Comments does not work:

    // this is a comment

    /* this is also a comment */

Floating point numbers

Floating point numbers are malformed when compiled, the following code:

    let age:number = 33.5;

Becomes this when compiled (int):

    int age = 33.5f;

Interfaces

Interfaces are currently not supported

    interface LabeledValue {
        label: string;
        value: number;
    }

Exports & Imports

Exports and imports are currently not supported:

    export * from "./ZipCodeValidator";  // exports class 'ZipCodeValidator

    ...

    import { ZipCodeValidator } from "./ZipCodeValidator";

Too many semi colons

The output basically looks like this right now:

    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
    ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Solutions

If you find any solution for any of these issues, feel free to create a pull-request... Also if you find any other issues, please report them.

Notes

Machine code

The compiler does not turn the typescript input to machine code, you should use a C compiler to do that. I would suggest using gcc.
