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).

v0.7.0 adds two supporting modules:

• [env]: runtime detection of whether ANSI output should be enabled. env::color_enabled respects NO_COLOR and FORCE_COLOR, falling back to TTY detection (isatty(1) on Unix, GetConsoleMode on Windows).
• strip: exposes strip::strip_ansi, which removes CSI escape sequences from a string. Useful for measuring display width, plain-text logging, or piping output to tools that do not interpret ANSI codes.

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