Colored Macro

Colored macro is a Rust crate for creating colored and formatted strings using ANSI codes in a readable way. It uses XML-like syntax:

<red>red text</red> <bold>bold text</bold> <green>{fmt_expr}</green>

The Problem

With current crates, messages quickly become hard to quickly understand at a glance. This is best explained with an example:

rust println!("[{}] ({}): {}", level.green(), timestamp.blue(), message.bold());

You can see that even with a simple message, the format string becomes hard to quickly understand, compared to the equivalent using this crate:

rust println!("{}", colored!("[<green>{level}</green>] (<blue>{timestamp}</blue>): <bold>{message}</bold>"));

Documentation

The following styles are available:

• Any CSS named color, as long as their alpha is 1.
• Any RGB color in the regular CSS format, as long as its alpha is 1 (e.g. rgb(10, 12, 200), #0012G4).
• reset (resets current styles)
• bold
• dim
• italic
• underline
• blink
• reverse
• hidden
• strikethrough

Styles can be nested:

rust colored_macro::colored!("<red>all red <yellow>yellow <blue>now to blue</blue> back to yellow</yellow> back to red</red>")
