Crate farben_core 

Core library for the farben terminal styling crate.

Provides the full pipeline for parsing farben markup strings into ANSI escape sequences: tokenization (lexer), ANSI encoding (ansi), rendering (parser), named style registration (registry), and error types (errors).

Typical usage flows through the lexer::tokenize and parser::render functions, with optional style definitions via the registry module and its macros.

Modules

ansi

ANSI SGR escape sequence encoding for farben styles.

debug

Inverse rendering: turn parsed tokens back into farben markup syntax.

degrader

Color degradation for terminals that lack truecolor support.

env

Runtime detection of whether ANSI color output should be enabled.

errors

Error types for farben markup tokenization and registry operations.

lexer

Tokenizer for farben markup strings.

parser

Token stream renderer.

registry

Global named style registry.

strip

Utilities for stripping ANSI escape sequences from strings.

Functions

active_stack

Returns a clone of the current persisted stack. Used by the parser at the start of render to resume from prior state.

clear_active_stack

Clears the persisted stack. Called by the upper layer after a non-bleed print (which appends \x1b[0m, so the terminal is back to a clean slate).

set_active_stack

Replaces the persisted stack. Used by the parser at the end of render to save its working state.
