Quanty is a text based program. In order to run it you need to make a text file that contains the commands you want to execute, then you run the program with as an input the name of the text file. Running such a program goes via the “terminal”. You can find the terminal in your launchpad under the subfolder other. Once you've opened the terminal a new empty window appears in which you can type. Welcome to the world of linux and text based interfacing as it was standard in the 1980's. From here you can control your computer with text commands. A few useful commands are:

  • ls - list the files in the folder you are in at the moment
  • cd - changes you to a new folder
  • pwd - shows you the folder you are in
  • open -t filename - opens the file with the name filename in a text editor

In order to find a full tutorial on linux you can google “linux bash shell commands”. This will give you more sites and information than you want to know.

We now need to place the program Quanty into a folder where you can run it easily from within the terminal. To do so we will create the folder “bin” in your home directory and add the bin to your path such that wherever you are your computer can always find Quanty. The first thing to do is to change to directory to your home (cd ~ [enter]). Next you create the folder bin in your home (mkdir bin [enter]). The last thing you do in the terminal is to add the program Quanty to your path (echo -e '\nexport PATH=“~/bin:\$PATH”\n' » .bashrc [enter]). You can test if the file .bashrc is correct by typing (open -t .bashrc [enter]). An other option to see your search path is to type (echo $PATH [enter]).

The last thing to do is to copy the program into your bin. For this you can use finder. From the terminal you can type (open bin -a Finder) and then drag and drop the program you downloaded into the folder bin.

You now can run the program from the terminal by typing (Quanty [enter]).

Run Quanty from the terminal

In order to run Quanty from the terminal you type Quanty followed by an enter. If you do so the program will place a small amount of text on your screen and then complain that it has nothing to do. If you want a real calculation you have to give Quanty a set of instructions as input. These are saved in text files and given as second argument in the terminal. For example you can type in the terminal:

echo 'print(“Hello World”)' > MyFirstQuantyProgram.Quanty

and then:

Quanty MyFirstQuantyProgram.Quanty

In order to do more elaborated calculations modify the input file. (open -t MyFirstQuantyProgram.Quanty [enter])
