uv-console

crates/uv-console/ is uv's terminal interaction layer — color management, progress bars, prompts, and detection of "is this a TTY?".

Purpose

uv's CLI output adapts to its environment: full colors and progress bars in an interactive terminal, plain text under CI=true, and JSON for --output-format json. Centralizing the detection and rendering avoids subtle inconsistencies across commands.

Key abstractions

• Terminal::detect() — distinguishes TTY / pipe / dumb-terminal.
• Colored output helpers built on anstream.
• Progress reporters (delegated to indicatif).
• Prompt helpers for uv auth login and similar interactive flows.

• uv-logging for tracing integration.
