Supported Characters

The | character will be replaced with a line break

Options

-h, --help

Type: <command>
Default value: none

This shows a list of all available options.

$ cfonts --help

-V, --version

Type: <command>
Default value: none

This shows the installed version.

$ cfonts --version

text

Type: <string>
Default value: ""

This is the "text input" to be converted into a nice font.
The | character will be replaced with a line break.

$ cfonts "Hello world"

-f, --font

Type: <string>
Default value: "block"

This is the font face you want to use. So far this plugin ships with with following font faces:

$ cfonts "text" --font "chrome"

• block [colors: 2] (default)
• slick [colors: 2]
• tiny [colors: 1]
• grid [colors: 2]
• pallet [colors: 2]
• shade [colors: 2]
• chrome [colors: 3]
• simple [colors: 1]
• simpleBlock [colors: 1]
• 3d [colors: 2]
• simple3d [colors: 1]
• huge [colors: 2]
• console [colors: 1]

-a, --align

Type: <string>
Default value: "left"

You can align your text in the terminal with this option. Use the keywords below:

• left (default)
• center
• right
• top (Will be ignored if used with the spaceless option)
• bottom (Will be ignored if used with the spaceless option)

$ cfonts "text" --align "center"

-c, --colors

Type: <string list>
Default value: ['system']

With this setting you can set the colors for your font. Use the below color strings or a hex color.
Provide colors in a comma-separated string, eg: red,blue. (no spaces)
If you use a hex color make sure you include the # prefix. (In most terminals wrap the hex in quotes)
The system color falls back to the system color of your terminal.

💡 There are environment variables that can affect the display of colors in your terminal.

• system (default)
• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white
• gray
• redBright
• greenBright
• yellowBright
• blueBright
• magentaBright
• cyanBright
• whiteBright
• #ff8800 (any valid hex color)
• #f80 (short form is supported as well)

$ cfonts "text" --colors white,"#f80"

-g, --gradient

Type: <string list>
Default value: false

With this setting you can set a gradient over your output.
This setting supersedes the color open.
The gradient requires two colors, a start color and an end color from left to right.
(If you want to set your own colors for the gradient, use the transition option.)
cfonts will then generate a gradient through as many colors as it can find to make the output most impressive.
Provide two colors in a comma-separated string, eg: red,blue. (no spaces)
If you use a hex color make sure you include the # prefix. (In the terminal wrap the hex in quotes)

• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white
• gray
• grey
• #ff8800 (any valid hex color)
• #f80 (short form is supported as well)

$ cfonts "text" --gradient red,"#f80"

-i, --independent-gradient

Type: <boolean>
Default value: false

Set this option to re-calculate the gradient colors for each new line.
Only works in combination with the gradient option.

$ cfonts "text|next line" --gradient red,"#f80" --independent-gradient

-t, --transition-gradient

Type: <boolean>
Default value: false

Set this option to generate your own gradients. Each color set in the gradient option will then be transitioned to directly. This option allows you to specify more than just two colors for your gradient.
Only works in combination with the gradient option.

$ cfonts "text" --gradient red,"#f80",green,blue --transition-gradient

-b, --background

Type: <string>
Default value: "transparent"

With this setting you can set the background colors for the output. Use the below color strings. Provide the background color from the below supported list, eg: 'white'

• transparent (default)
• black
• red
• green
• yellow
• blue
• magenta
• cyan
• white
• blackBright
• redBright
• greenBright
• yellowBright
• blueBright
• magentaBright
• cyanBright
• whiteBright
• #ff8800 (any valid hex color)
• #f80 (short form is supported as well)

$ cfonts "text" --background "Green"

-l, --letter-spacing

Type: <integer>
Default value: 1

Set this option to widen the space between characters.

$ cfonts "text" --letter-spacing 2

-z, --line-height

Type: <integer>
Default value: 1

Set this option to widen the space between lines.

$ cfonts "text" --line-height 2

-s, --spaceless

Type: <boolean>
Default value: false

Set this option to false if you don't want the plugin to insert two empty lines on top and on the bottom of the output.

$ cfonts "text" --spaceless

-m, --max-length

Type: <integer>
Default value: 0

This option sets the maximum characters that will be printed on one line.
cfonts detects the size of your terminal but you can opt out and determine your own max width.
0 means no max width and the text will break at the edge of the terminal window.

$ cfonts "text" --max-length 15

-r, --raw-mode

Type: <boolean>
Default value: false

Set this option to make sure cfonts used CRLF (\r\n) over the default LF (\n) line breaks.
This could be useful for terminal raw modes or on older windows machines.

use crossterm::terminal;
use std::io::Write;
use cfonts;

fn main() -> std::io::Result<()> {
	terminal::enable_raw_mode()?;

	cfonts::say(cfonts::Options {
		text: String::from("Hello|world"),
		raw_mode: true,
		..cfonts::Options::default()
	});

	std::io::stdout().flush()?;
	terminal::disable_raw_mode()?;
	Ok(())
}

-e, --env

Type: <string>
Default value: cli

This option lets you use cfonts to generate HTML instead of ANSI code.
Note that max-length will be set to very large.

$ cfonts "text" --env browser

Consistency

cfonts detects what colors are supported on your platform. It sets a level of support automatically. In cfonts you can override this by passing in the FORCE_COLOR environment variable.

FORCE_COLOR=3 cfonts "hello world" -c "#0088ff"

You can also use the NO_COLOR environment variable to set no color output for environments like CI.

NO_COLOR="" cfonts "hello world" -c "#0088ff"

💡 FORCE_COLOR overrides NO_COLOR if both are set.
