Crate zcolorizer 

zcolorizer

A real-time log colorizer — a Rust port of ccze and the pygments regex→token idea — with fully customizable rules and swappable themes.

The pipeline is three decoupled pieces:

1. rules — regexes that tag spans of a line with a semantic token (date, error, host, …). Named capture groups make one regex paint several fields. Rules live in the config, so users own them entirely.
2. theme — a named map from token → color::Style. The active theme decides what each token looks like; swapping it recolors everything (the “pick the theme from zgui” flow). The flagship is theme::cyberpunk.
3. engine::Colorizer — runs the compiled rules over each line and paints the claimed spans with the theme.

config::Config ties them together from a TOML file.

Quick start

use zcolorizer::Colorizer;
let cz = Colorizer::from_config(&zcolorizer::config::Config::default(), None).unwrap();
let painted = cz.colorize_line("Jun 27 14:03:11 host sshd[1234]: ERROR bad login");
assert!(painted.contains("\x1b["));

Modules

color

Color and text-style model plus ANSI SGR rendering.

config

Configuration: the on-disk TOML that makes rules and themes fully customizable.

engine

The colorization engine: turn a plain line into an ANSI-colored line by running the compiled rules and painting the spans they claim with the active theme’s styles.

error

Crate error type.

modules

Format-specific colorizers — the port of ccze’s plugins (mod_*.c).

modules_modern

Modern log-format modules — the formats you actually tail today that ccze (2003) never covered: systemd/journald, sshd/auth, kernel, nginx, JSON & logfmt, Postgres/MySQL/Redis/Mongo, Docker/Kubernetes, app frameworks, and common network services. Each was researched against real on-disk lines.

rules

Rules: regex patterns that tag spans of a line with a semantic token.

theme

Themes: a named mapping from semantic token → Style.
