Turing is a free and cross-platform app whose main goal is to assist the learning of algorithms and programming languages by providing easy-to-use development tools to all.

It provides a lighter alternative to the well-known Algobox, which is the currently de-facto widely used solution.

Note: Turing was originally meant to be a school project for the CS class. Don't expect enterprise-grade code here. We do our best to keep the whole codebase clean, but some parts are still undocumented and not covered by unit tests.

Quid, quis, quomodo?

Turing is written in Python 3.6 and uses the PyQt5 framework for its GUI. It provides two work modes:

  • Algorithm mode
    • Uses a "natural" pseudocode language similar to the one used in Algobox and school books.
    • Assisted development
  • Program mode
    • Uses Python, for the more experienced

In both modes, the code can be debugged and executed step-by-step to facilitate the problem-solving side of development.

Using Turing

Turing is cross-platform, but has only been tested on Windows and Linux-based operating systems. macOS should be supported, but no guarantee is made of that.

Using the package (recommended for Linux)

A package is available for Ubuntu and Debian. You can install it like this:

sudo apt-get install turing

If it does not work, use the pre-compiled binaries available below.

Using pre-compiled binaries (recommended)

Click on the Releases tab at the top of the page and download the release corresponding to your OS.

  • windows32: Windows 32 bits (7 or later)
    • tested on 10 x64
  • nix64: Linux 64 bits (Ubuntu 14.04 / Debian 8 or later)
    • tested on 18.04
  • osx: macOS 64 bits (10.13 High Sierra or later)
    • tested on 10.13

Using the source code (advanced users)

Python 3.6 required!

You need to have python3 point to Python 3.6 in your shell! Either use an alias in your .bashrc or a distribution that comes with Python 3.6.

It uses the following libraries:

  • PyQt 5 - UI framework
  • pyQode - PyQt code editor with syntax highlighting
  • Pygments - Syntax highlighter for printing code files
  • pep8 - Code quality checker

First, install everything using pip:

pip install --ignore-installed -r requirements.txt

Note: if you have Python 2.x installed on your computer (which is the case on 99% of Linux distributions), the old pip may be present in PATH and interfere with the above command line. If that happens, try using pip3 instead of pip. Of course, it must be the pip paired with the installed Python3 (so you may need to use pip3.6 instead).

Next, open the src/ folder and use run.bat or source depending on your operating system.

Building Turing (using pyInstaller)

You need:

  • Python 3.6 (python3.6)
  • Python 3.6 dev package (python3.6-dev)
  • Qt5 lrelease (qt5-dev-tools)
