paskal's Introduction

Paskal

Compiler for pascal like language. Also checkout paskal-client where you can run paskal from your browser.

Building

The project requires Go LLVM bindings. Please see https://github.com/llvm/llvm-project/tree/master/llvm/bindings/go for their installation. After the bindings are installed and built, simple go build should compile the project.

Usage and Hello world

program main

begin
  printf("Hello, world!")
end

Program above can be compiled with paskal hello.pas hello.o. Clang can be then used to link the program to make an executable e.g. clang hello.o -o hello.

Currently supported features

Datatypes

  • Real
  • Integer
  • Boolean
  • Character
  • Static arrays

Example programs

program main

begin
  random := 42
end

begin
  if random() is 42 then begin
    // ...
  end else begin
    // ...
  end
end
program main
var arr : array[2] of real
realPointer : ^real

begin
  arr[0] := 1.0
  realPointer := @arr[1]
  ^realPointer := 5.0
  printf("Array %f %f", arr[0], arr[1])
