Project Description

Hackertype lets you pretend you are the elite hacker you always you knew you were in your heart of hearts, right from the CLI.

CLI Tools


python -m team13hackertype hackertype <language:[python|java]>

Run the classic hackertype app from the old internet days. Press keys to generate programming snippets from the given language and press esc to finish. Currently supported languages are python and java.


python -m team13hackertype penetrate <language> <text:optional>

Simulate a penetration hack. The program will display your text in a scary looking font before launching into hackertype of your given language. The supported language and usage is the same as hackertype. When done, the program will tell you that you are logging out.


python -m team13hackertype -h

Happy hacking!

Usage in a Python project

While hackertype is meant to be, for the most part, a fun, whimsical command line app, there are a few functionalities that may be imported into your project.


looping_string(string: str, chunk_size: int) -> Iterator[str]

Creates an iterator that loops over a string forever. Each iteration returns the next chunk of the string of length ‘chunk_size’.

  • Parameters
    • string: str
      • The string that is being looped.
    • chunk_size: int
      • The size of the substring that is returned.
  • Returns
    • Iterator[str]
      • An iterator of substrings of string where each substring has size chunk_size. This iterator has no stop.


get_code_snippet(language: str) -> str

Given a coding language, returns a large code snippet written in that language as a string. Currently, supported values for lanuage are ‘python’ and ‘java’. The code snippet for Python was borrowed from TensorFlow and the snippet for Java was borrowed from Spring.

  • Parameters
    • language: ‘python’ | ‘java’
      • The language of the code snippet.
  • Returns
    • str
      • The code snippet written in the language programming language.
  • Raises
    • NotImplementedError
      • Raised if we do not have a snippet for the language provided. Right now, we support python and java.
    • IOError
      • Raised if there was another IO problem with opening the file.
    • Exception
      • Raised for any other miscellaneous exceptions occuring when opening the file.


hackertype(language: str, speed: int = 20) -> None

Starts listening for keyboard presses. On key press, prints out speed amount of characters from a code snippet written in the language coding language, until the Esc key is pressed. Note that this function is not asynchronous. This means that after running, it will wait for the Esc key before continuing program execution.

  • Parameters
    • language: ‘python’ | ‘java’
      • The coding language of the hacker snippet to be printed.Supported values include ‘python’ and ‘java’.
    • speed: int, optional, default: 20
      • The number of characters to print out on a single key press.
  • Returns
    • None
  • Raises
    • Same as hackertype.get_code_snippet.


penetrate(language: str, text: str = “DARKWEB”, loading_bar_speed: float = 1.0, emphasis_style: str = “bold red”, notification_style: str = “bold green”) -> None

Simulates a penetration hacking attempt in the standard output. Logs out text in ASCII text before launching into hackertype. Upon escaping, displays a logging out message. Note that this function utilizes hackertype.hackertype and is also not asynchronous.

  • Parameters
    • language: str
      • The coding language of the hacker type to be printed.Supported values include ‘python’ and ‘java’. See hackertype.hackertype.
    • text: str, optional, default: “DARKWEB”
      • The text shown in the banner. Length of string must be less than 8.
    • loading_bar_speed: float, optional
      • The speed of loading bar progress.
    • emphasis_style: str, optional, default: “bold red”
      • The style for Console print of emphasized text. For options, see Rich docs.
    • notification_style: str, optional, default: “bold green”
      • The style for Console print of emphasized text, used in show_header. For options, see Rich docs.
  • Returns
    • None
  • Raises
    • NotImplementedError
      • Raised if we do not have a snippet for the language provided. Right now, we support python and java. See hackertype.hackertype.
    • ValueError
      • Raised if the given style is not provided.
    • Exception
      • Unexpected exception that may arise from IO or console issues.
