WRITE A SIMPLE TERMINAL APP MAC CODE

There is nothing like watching people use your programs to make you code more defensively. If you see people using your applications at an early stage, you will write better code.

Terminal apps do have users, even if that is just you, and maybe your friends or family.

You will learn about user interaction issues.

Terminal applications let you focus on getting the logic right, rather than building a graphical interface. That has gotten pretty simple these days, but it is still more complicated than what you will do when writing terminal applications. When you want some information in a graphical program, you have to build text boxes and buttons for submitting information. To get input in a terminal, you issue the command input('Please tell me some information: ').

When you write more complex graphical applications, there are layers of abstraction between you and the user.

Terminal apps let you play with complex code, without layers of abstraction between you and the user.

When you write an application, you are creating an environment in which people work and play. Applications, by their nature, solve interesting problems.They can be much more fun and satisfying to write than simpler programs.Even so, there are a number of reasons to consider writing a few terminal apps of your own. Unless you see people working in technical fields on a regular basis, it's quite possible you have not seen many people using terminal applications.

Let's figure out how to write some of our own. There are quite a few other terminal apps. It is much less intuitive than nano at first, but once you learn how to use it you can edit files extremely quickly. If you have typed anything, you will be given the option to save your file. If you are editing files on a remote server, you need a terminal-based editor.This is a text editor that runs in the terminal.Open a terminal and enter nano test_file.txt.You can press 'q' to quit this application.You will see a bunch of processes that are running on your system, sorted by which ones are using the most resources.They are applications that run in the terminal, and you can write your own apps in Python. Many of these are not written in Python, but that doesn't matter. If you are on a linux system, you can run some terminal apps right now. In terminal applications, this often means something like entering 'q' or 'quit'. By learning a few more techniques such as clearing the terminal screen and 'pickling' data, you can create full-fledged standalone applications that run in the terminal.Ī terminal app starts just like any other program, but it finishes when the user selects an action that causes the program to quit. By now, you have seen that most of the output from your programs is printed to the terminal. A terminal application is simply an application that runs inside the terminal.
