AdvancedPrinter

Small terminal printing helpers for Python: colours, styles, inline text, readable status messages, and Unicode-aware frames. Built on Python's standard streams and one runtime dependency, wcwidth.

Requires Python 3.10+. Upgrading from 1.x? Read the migration guide.

Install

python -m pip install --upgrade AdvancedPrinter
python -m advancedprinter

Print with colours and styles

from advancedprinter import print

print("Repository updated", color="green", style="bold")
print("Downloaded", 3, "packages", sep=" | ")
print("Custom colour", color="#ff8800", background="black")
print("Combined styles", style="bold italic underline")

The original short arguments and class imports still work:

from advancedprinter import AdvancedPrinter as ap

ap.print("Green text", c="green")
ap.print("Bold italic text", s="b-it")
ap.print("White on blue", c="white", b="blue")
ap.help()

print() supports the standard sep, end, file, and flush parameters. Colours may be palette names, #RRGGBB, RGB tuples, or xterm indexes from 0 to 255. Unknown names and conflicting aliases raise descriptive exceptions.

Terminal output and log files

from advancedprinter import Printer

console = Printer(color_mode="auto")
console.success("Repository updated")
console.warning("Using cached release information")
console.info("Downloaded", 3, "packages")
console.error("Download failed")  # stderr by default

with open("sync.log", "w", encoding="utf-8") as log:
    console.print("This file gets plain text", color="green", file=log)

The default auto policy inspects the actual destination stream. Redirected output, pipes, and TERM=dumb get plain text. Non-empty NO_COLOR disables colours in automatic mode while retaining attributes such as bold.

• color_mode="always" explicitly enables styling, even in files or with NO_COLOR.
• color_mode="never" removes all ANSI escape sequences, including inline ones.
• color_system="auto" detects standard, 256-colour, or truecolour support from TERM and COLORTERM. Set the depth explicitly when detection is insufficient.

Printers have independent configuration. No global setup or monkey-patching is required. file=None resolves the current sys.stdout at the time of each call.

Inline formatting and pure rendering

from advancedprinter import format_text, line, print

name = line("Kaloian", color="blue", style="bold")
print(f"Hello, {name}!")

# Outer formatting resumes after the inner span ends.
print("Before " + line("inside", color="blue") + " after", color="red")

plain = format_text("No escape codes", color="green", color_mode="never")

line() is an alias of format_text(). These pure functions return strings and default to ANSI output, independent of the environment. They do not inspect stdout; the printing operation applies the destination's policy. Use color_mode="never" when you need a plain string directly. The pure functions require explicit policies; auto is only available on output operations.

Frames

from advancedprinter import Printer, format_frame

console = Printer()
console.frame(
    "Downloaded 3 packages\n中文 and emoji 👋 are measured in terminal cells",
    title="Repository sync",
    border="rounded",
    border_color="cyan",
    max_width=48,
    padding=1,
)

text = format_frame("Ready", border="double", color_mode="never")
console.print(text)

Borders: basic, basic2, single, double, and rounded. Frames support colours, titles, horizontal padding, alignment, wrapping, and ascii=True. width and max_width include borders and padding. Indentation, trailing spaces, and blank lines are preserved; use dedent=True to remove common indentation. A character or title that cannot fit raises ValueError rather than breaking the frame. frame() prints; format_frame() returns a string.

Input, themes, and logging

from advancedprinter import MessageStyle, Printer

console = Printer(
    theme={
        "success": MessageStyle(color="cyan", style="bold", prefix="DONE"),
    }
)
console.success("All tasks complete")
answer = console.input("  Continue? ", color="yellow")

Input prompts are preserved exactly. input() without a prompt is supported; EOF and keyboard interrupts behave normally.

import logging
import sys
from advancedprinter import ColorFormatter

handler = logging.StreamHandler(sys.stderr)
handler.setFormatter(
    ColorFormatter(
        "%(levelname)s: %(message)s",
        stream=handler.stream,
    )
)
logger = logging.getLogger("sync")
logger.addHandler(handler)
logger.setLevel(logging.INFO)
logger.info("Repository updated")

Use an ordinary logging.Formatter for file handlers. Pass the console handler's actual stream to ColorFormatter; log records are not modified.

Documentation and development

• API reference and full palette
• Migration from 1.x
• Release and PyPI setup
• Changelog
• Contributing

CI tests Python 3.10–3.14 on Linux, Windows, and macOS, checks formatting and static types, and validates the built wheel and source distribution. Publishing a GitHub Release runs the same checks, verifies the tag matches the package version, and uploads the validated distributions through PyPI Trusted Publishing. The one-time publisher setup is described in the release guide.

Terminal rendering still depends on fonts and terminal support. Italic and strike-through are not available everywhere; emoji widths can vary between terminals. Windows automatic mode uses VT support where available and falls back to plain output otherwise. Border characters fall back to ASCII when the stream encoding requires it; non-encodable user content still raises the normal error.
