tdraw

Inspired by Explaining Code using ASCII Art.
Supports box / line drawing, text input and eraser.
wfn's fork from aca/tdraw

Install

go get -u github.com/aca/tdraw

or download from https://github.com/aca/tdraw/releases

Usage

1. Pipe output to file, easy way:

tdraw > draw.txt

2. Explicitly ask it to save to file (overwrites existing one), optionally with parameter resolved:

Usage of ./tdraw:
  -filename string
    	output filename (optional params for it: datetime) (default "drawing_{{.datetime}}.txt")
  -output-to-file
    	on exit, save output to text file (disabled by default)

Filename is optional and it's convenient to leave it out:

% ./tdraw -output-to-file
  [program runs, user presses ctrl+c at some point]
Output file: drawing_2025-03-23_130808.txt

This was added for more flexibility in the feature, e.g. would be nice to

• read in txt file
• keep track of shapes as entities
• save entity list (separate file optionally), re-arrange shapes to fit new shapes
  • overall would be great to have small subset of draw.io functionality but with dynamic context-aware shape management
