About:
Sequin is a command-line utility that decodes ANSI escape sequences into human-readable descriptions. It helps developers understand complex terminal control codes, such as color and cursor movements, by providing clear textual explanations. This tool simplifies debugging and learning for anyone working with terminal output and TTY sequences.

Key Features:

Decodes standard ANSI escape sequences
Provides human-readable output
Simple command-line interface
Useful for debugging terminal output

Use Cases:

Debugging scripts that output colored text
Learning how ANSI escape codes function
Analyzing raw terminal logs

Alternatives:

tput – tput is used to query terminal capabilities, while sequin specifically decodes raw sequence strings.
cat -v – cat -v displays non-printing characters, but sequin interprets them into plain English.
