Objeck is an object-oriented computer language with functional features. The language has ties with Java, Scheme and UML. In this language all data types, except for higher-order functions, are treated as objects.

Objeck is a general-purpose programming language with an emphasis placed on simplicity. The programming environment consists of a compiler, virtual machine and command line debugger.

class Hello {
  function : Main(args : String[]) ~ Nil {
    "Hello World"  PrintLine();
    "Καλημέρα κόσμε"  PrintLine();
    "こんにちは 世界"  PrintLine();

Building on Linux and macOS:

  • Install required libraries: sudo apt-get install build-essential git libssl-dev unixodbc-dev libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev libsdl2-mixer-dev
  • cd to objeck-lang/core/release and run ./ with the parameter 32, 64 or osx representing the bit version of Linux
  • Build output with binaries and documentation will be located in objeck-lang/core/release/deploy
  • Reference objeck-lang/core/release/deploy/readme.html to set paths and find examples

Building on Windows:

  • With Visual Studio 2019 or later open objeck-lang/care/release/objeck.sln
  • Ensure build completes successfully
  • To build everything, cd to objeck-lang/care/release and run deploy_amd64.cmd deploy
  • Build output with binaries and documentation will be located in objeck-lang/core/release/deploy64
  • Reference objeck-lang/core/release/deploy64/readme.html to set paths and find examples
