ANSI Terminal
ANSI Terminal
This program depicts the use of ansi_term
crate and how it is used for controlling colours and formatting, such as blue bold text or yellow underlined text, on ANSI terminals.
There are two main data structures in ansi_term
: ANSIString
and Style
. A Style
holds stylistic information: colours, whether the text should be bold, or blinking, or whatever. There are also Colour variants that represent simple foreground colour styles. An ANSIString
is a string paired with a Style
.
Note: British English uses Colour instead of Color, don’t get confused
Printing colored text to the Terminal
use ansi_term::Colour; fn main() { println!("This is {} in color, {} in color and {} in color", Colour::Red.paint("red"), Colour::Blue.paint("blue"), Colour::Green.paint("green")); }
Bold text in Terminal
For anything more complex than plain foreground colour changes, the code
needs to construct Style
struct. Style::new()
creates the struct,
and properties chained.
use ansi_term::Style; fn main() { println!("{} and this is not", Style::new().bold().paint("This is Bold")); }
Bold and colored text in terminal
Colour
implements many similar functions as Style
and can chain methods.
use ansi_term::Colour; use ansi_term::Style; fn main(){ println!("{}, {} and {}", Colour::Yellow.paint("This is colored"), Style::new().bold().paint("this is bold"), Colour::Yellow.bold().paint("this is bold and colored")); }
