Text-Based Browser in Python

About

Sometimes you need to read online documentation or find something on the Internet from the command line or terminal. So, let's use Python to create a text-based browser! Of course, making a real, full-blown browser is a very difficult task. In this project, you'll create a very simple browser that will ignore JavaScript and CSS, won't have cookies, and will only process a limited set of tags. Still, it will be useful and, most importantly, fun to program!

Learning outcomes

I learnt how HTTP works and how to handle its protocols using Python. I also learnt all about Python input/output, as well as parsing HTML, got to know BeatifulSoup and Colormap libraries.

Functions

• The program accepts commands and URLs of websites
• The program downloads page from given URL in CLI
• The program then parses the html page, extracts all the text and prints it to CLI
• The program prints links in blue and regular text in white
• The program has a simlple history and can print already visited pages using short name

CLI arguments

The programm accepts 1 CLI argument - name of the folder to use for saved pages, if no name is passed, the programm will create default tmp folder in the root directory and delete it on exit command

Example: python browser.py name_of_directory will create directory with name "name_of_directory" python browser.py will create default directory with name "tmp"

Menu commands

 - url of the page you would like to visit
 - "back" to print previously visited page
 - "exit" to exit the program

Example of running programm
