# Terminal Capability Detector Detect terminal capabilities for adaptive CLI output. ## Capabilities - Detect color support levels - Check TTY status - Get terminal dimensions - Detect Unicode support - Check for CI environment - Configure adaptive output ## Generated Patterns ```typescript import process from 'process'; import tty from 'tty'; export interface TerminalCapabilities { isTTY: boolean; colorLevel: 0 | 1 | 2 | 3; supportsUnicode: boolean; columns: number; rows: number; isCI: boolean; } export function detectCapabilities(): TerminalCapabilities { const isTTY = tty.isatty(1); const isCI = Boolean(process.env.CI || process.env.CONTINUOUS_INTEGRATION); let colorLevel: 0 | 1 | 2 | 3 = 0; if (isTTY && !process.env.NO_COLOR) { if (process.env.COLORTERM === 'truecolor') colorLevel = 3; else if (process.env.TERM?.includes('256color')) colorLevel = 2; else if (process.env.TERM && process.env.TERM !== 'dumb') colorLevel = 1; } const supportsUnicode = process.platform !== 'win32' || process.env.WT_SESSION || process.env.TERM_PROGRAM === 'vscode'; return { isTTY, colorLevel, supportsUnicode, columns: process.stdout.columns || 80, rows: process.stdout.rows || 24, isCI, }; } ``` ## Target Processes - cross-platform-cli-compatibility - cli-output-formatting - progress-status-indicators
