Termi-link

github.com/king8fisher/termi-link

Published to

npmjs.com/package/termi-link

This library provides clickable terminal links for terminals that support them. It is designed to seamlessly replace popular terminal-link.

Reason

https://github.com/sindresorhus/terminal-link/issues/18 - terminal-link unfortunately adds a %E2%80%8B (Zero Width Space (ZWSP) character in Unicode, code point U+200B) to the start and end of the link in unsupported terminals, which makes links lead to 404 at least on Windows.

Precise Colors

github.com/king8fisher/precise-colors

Published to

npmjs.com/package/precise-colors

This library converts colors between various models without performing any rounding.

The idea is that if a non-trivial conversion is needed, you would perform a sequence of conversions and apply rounding only at the very end, minimizing mathematical errors along the way.
