Installation

BEFORE YOU START CODING: ezr² is still in pre-release status. That means ezr² might get backwards-incompatible updates every now and then.

Now, to install ezr² on your PC, follow these steps:

Windows (32 and 64 bit)

  1. Download the latest release of ezr² (ezrSquared.Installer.Windows.32-bit.exe for 32-bit systems or ezrSquared.Installer.Windows.64-bit.exe for 64-bit systems) from GitHub.
  2. Run the installer and go through the installation.
  3. Verify that ezr² is installed by running ezrSquared in a terminal - the ezr² biShell (built-in shell) should open (press Ctrl+C to exit).
  4. Start coding!

Linux (64 bit)

  1. Download the latest release of ezr² (ezrSquared.Linux.tar.xz) from GitHub.
  2. Extract the tar.xz file to a folder of your choice.
  3. Add the folder to your PATH environment variable.
  4. Verify that ezr² is installed by running ezrSquared in a terminal - the ezr² biShell (built-in shell) should open (press Ctrl+C to exit).
  5. Start coding!

Android

Check out ezr² Portable Interpreter on Google Play, an interpreter made with the help of ezr² Net4.8 in Unity!

Other

For other OSes you can clone the repository, and compile your own build. If you’re a contributor, feel free to add the build to the latest release.

If you are interested in how ezr² was embedded to the portable interpreter, check out the C# in ezr² page.

Usage

An ezr² script has the extension .ezr2. To run an ezr² script, use the ezrSquared command followed by the path to the script file:

> ezrSquared hello.ezr2
Use the "ezrSquared" command without any arguments to start the biShell:

> ezrSquared
You can type any valid ezr² expression in the shell and see its result.

Documentation

The official documentation for ezr² is available in the Introduction and Documentation page, but is still work in progress. Meanwhile, check out some example programs in GitHub.

The offline version of the ezrSquared website was made possible with Jekyll Offline. The documentation is packaged with the Windows installer. For other OSes, download and extract ezrSquared.Offline.Documentation.zip, which is available for download with each release on GitHub.
