purdy 0.2.0

Terminal based code snippet display tool

During talks or screencasts I don’t want to be typing code, it is too error prone and too likely to mess up my speaking flow. “purdy” takes snippets of code and displays them to a terminal using Pygments colourization. It listens for input and shows a line as if it is being typed each time you press enter.

Example Usage:

$ purdy code-snippet.py

Running the above command will clear the console and start typing the code snippet. Output is paused when it sees a REPL prompt (“>>> “). Pressing any key (except “q”) will continue the typing. Lines starting with a prompt mimic typing, lines not on a prompt are output immediately.

Once the code has been displayed, further key presses are ignored. At any time you can press “q” to quit.

Command Line Options

-c, --continuous

Instead of waiting for key presses, display the whole file

-x16

purdy defaults to using 256 colour mode in the terminal. This flag forces it to use 16 colour mode

-l, --lexer

Default lexer is Python Console lexer (‘con’), using this parameter you can also change it to a Python 3 code lexer (‘py3’)

-d, --delay DELAY

change the amount of delay between “typed” letters. Defaults to 130ms. Value given in milliseconds. Mutually exclusive with the “–wpm” option

-w, --wpm WPM

specify the typing speed in Words Per Minute. Mutually exclusive with the “–delay” option

--variance VARIANCE

to make the typing look more real a random value of plus or minus “VARIANCE” is added to the typing delay. Default value for this is 30ms. Value given in milliseconds.

--version

Display pgraom version and exit

--help

Display help information

Installation

$ pip install purdy

Coding With Purdy

The “purdy” script is fairly simple. You can also create programs using the purdy library. Your programs can have much more complicated interactions, including having split screens, highlighting lines and more.

Supports

purdy has been tested with Python 3.7
