Termal

crates.io donwloads

Rust library for terminal features with ansi escape codes.

Currently the library contains the ansii codes, and a special macro. Works for text styles, colors and moving the cursor.

Example

With macro

use termal::*;

// you can use a special macro to inline the color codes, this will write
// italic text with yellow foreground and reset at the end.
printcln!("{'yellow italic}hello{'reset}");

// the macro also supports standard formatting
printcln!("{'yellow italic}{}{'reset}", "hello");

// you can also use short versions of the codes
printcln!("{'y i}{}{'_}", "hello");

// you can also use true colors with their hex codes
printcln!("{'#dd0 i}{}{'_}", "hello");

Without macro

// Move cursor to position column 5 on line 7 and write 'hello' in italic
// yellow

use termal::codes::*;

println!("{}{YELLOW_FG}{ITALIC}hello{RESET}", move_to!(5, 7));

The macros such as move_to! can accept either literals or dynamic values. Its main feature is that if you supply literals, it expands to a string literal with the ansi code. If you however supply dynamic values it expands to a format! macro:

use termal::codes::*;

let a = move_to!(5, 7);
// expands to:
let a = "\x1b[5;7H";

let b = move_to!(2 + 3, 7);
// expands to:
let b = format!("\x1b[{};{}H", 2 + 3, 7);

If you know the values for the arguments you can also use the *c macros:

use termal::formatc;

// the spaces, or the lack of them is important
let a = formatc!("{'move_to5,7}");

Gradients

Youn can create gradients with the function termal::gradient:

use termal::*;

// This will create foreground gradient from the rgb color `(250, 50, 170)`
// to the rgb color `(180, 50, 240)`
printcln!("{}{'_}", gradient("BonnyAD9", (250, 50, 170), (180, 50, 240)));
