Utilities

link(text, url, options?)

Build a clickable terminal hyperlink using the OSC-8 escape sequence. Renders as a real clickable link in modern terminals (iTerm2, Windows Terminal, GNOME Terminal, Kitty, Wezterm, VSCode’s integrated terminal). Falls back to text (url) everywhere else.

import { link, colors } from "@mongez/copper";

console.log(`See ${link("the docs", "https://github.com/hassanzohdy/copper")}`);
console.log(`Report bugs at ${colors.cyan(link("issues", "https://github.com/hassanzohdy/copper/issues"))}`);

Option	Default	Behavior
fallback	"text-and-url"	Print text (url) when ANSI is unsupported
fallback: "text-only"	—	Print only text when unsupported

stripAnsi(input)

Remove every ANSI escape sequence — colors, modifiers, cursor moves, and OSC-8 hyperlinks.

import { stripAnsi, colors, link } from "@mongez/copper";

stripAnsi(colors.red.bold("error"));                         // "error"
stripAnsi(link("docs", "https://example.com"));              // "docs"
stripAnsi("plain");                                          // "plain"
stripAnsi(42);                                               // "42"

Use this when:

• Asserting on the visible output of a colored function in tests.
• Measuring the visible width of a string for layout (lengths of raw strings include the invisible ANSI bytes).
• Writing colored content to a file that should not carry ANSI.

symbols

Glyph set with automatic ASCII fallbacks on classic Windows cmd.exe. Detection: if process.platform === "win32" AND none of WT_SESSION / TERM_PROGRAM / TERM=xterm-256color is set, use the ASCII set.

Key	Fancy	ASCII fallback
tick	✔	√
cross	✖	×
info	ℹ	i
warning	⚠	‼
arrow	→	->
pointer	❯	>
ellipsis	…	...
bullet	•	*
line	─	-
spinner	["⠋", "⠙", "⠹", "⠸", "⠼", "⠴", "⠦", "⠧", "⠇", "⠏"]	`[”-”, ”\”, "

import { symbols, colors } from "@mongez/copper";

console.log(`${colors.green.bold(symbols.tick)} Saved`);
console.log(`${colors.red.bold(symbols.cross)} Failed`);
console.log(`${colors.gray(symbols.pointer)} Press any key`);

isColorSupported and detectColorSupport()

import { isColorSupported, detectColorSupport } from "@mongez/copper";

if (isColorSupported) {
  // safe to emit ANSI
}

// Re-evaluate at runtime (after env mutation, e.g. inside a CLI flag parser):
const enabled = detectColorSupport();

isColorSupported is the cached result of detectColorSupport() at module-load time. The detection rules are documented in the overview skill.
