Why RazTint?

[!NOTE] RazTint believes terminal styling should be zero-friction: no dependencies, no configuration files, no guessing the user's environment. It figures out the rest so you can focus on your CLI logic.

• Zero dependencies — Python ≥ 3.10 standard library only
• Smart icons — Nerd Font → Unicode → ASCII fallback, with environment-aware detection
• Cross-platform behavior — Linux, macOS, and Windows, including CI
• Minimal setup — import and use; detection is cached and fast

---

Features

• 🎨 Full ANSI 16-color foreground and background support
• 🌈 Extended colors: 24-bit True Color (rgb, hex_color) and 256-color (color256)
• ✨ Text styles: bold, dim, italic, underline, strikethrough
• 🔍 Status icons with three-tier fallback and environment-aware detection
• 🖌️ paint() — one call for color, background, styles, and icons
• 🎯 Intents — semantic presets (success, danger, warning, …)
• 🔒 Redaction — mask secrets in logs before printing
• 💡 Fully type-hinted public API (py.typed, IDE autocompletion)
• ⚙️ Configurable via environment variables (NO_COLOR, RAZTINT_FORCE_COLOR, …)

---

Requirements

• Python 3.10 or newer

---

Installation

pip install raztint

From source:

git clone https://github.com/razbuild/raztint.git
cd raztint
uv sync

---

Quick Start

from raztint import ok, paint

print(f"{ok()} File saved.")
print(paint("Connection failed.", color="red", icon="err"))

# Semantic intents
print(paint("Deployment complete.", intent="success"))

# Mask secrets before logging
print(paint("password=1234", intent="debug", redact=True))  # password=****

Standalone redaction without formatting:

from raztint import redact

print(redact("password=supersecret api_key=ghp_abc123"))
# password=**** api_key=****

See Getting Started for more examples. Icon output depends on the detected mode: Nerd Font, standard Unicode, or ASCII.

Extended Colors

RazTint supports 24-bit True Color and 256-color mode via raw ANSI escape sequences — no extra dependencies.

from raztint import rgb, hex_color, color256
from raztint import bg_rgb, bg_hex_color, bg_color256

# True Color foreground
print(rgb("This is orange text", 255, 100, 50))
print(hex_color("Same orange via hex", "#FF6432"))

# True Color background
print(bg_rgb("Orange background", 255, 100, 50))
print(bg_hex_color("Same via hex", "#FF6432"))

# 256-color
print(color256("Orange via 256 palette", 208))
print(bg_color256("Background 256", 208))

# Compose freely with existing helpers
from raztint import bold
print(bold(rgb("Bold True Color text", 0, 200, 0)))
print(rgb(bg_color256("White on orange bg", 208), 255, 255, 255))

[!NOTE] Terminal support: True Color requires a terminal that supports TERM=xterm-256color or similar. NO_COLOR and RAZTINT_FORCE_COLOR are respected.

---

Known Limitations

• Python 3.10+ — older versions are not supported.
• Font detection relies on OS tools — fc-list (Linux), system_profiler (macOS), PowerShell (Windows). Set RAZTINT_SKIP_SYSTEM_FONT_SCAN=1 in sandboxed environments.
• Strict NO_COLOR compliance — when NO_COLOR is set, all colour output is suppressed regardless of other settings.
