Usage

Acquerello allows to add coloring to terminal in a really easy way.

Colorize templates

To colorize a template using template syntax, simply use the colorize function.

import { colorize } from 'acquerello' 
 
console.log(colorize('{{red}}This is in red, {{green underline}}this in green underlined{{-}}, this in red again.'))

The template recognizes styles between double curly braces and the token {{-}} as universal closing tag (which also restores the previous style).

Acquerello supports all colors codes recognized by ansi-style (and therefore by chalk).

The closing tag at the end of the string can be omitted, since acquerello will append the global reset style (\x1b[0m) if any style was set.

If you want to discard the styles to be restored, use the {{reset}} token.

Setting custom styles

If you want to define custom styles, use the addCustomStyle function.

import { colorize, addCustomStyle } from 'acquerello' 
 
addCustomStyle('important') 
console.log(colorize('{{important}}This is in red, underlined.{{-}}'))

256 and 16 millions colors support

acquerello supports 256 ANSI codes and 16m RGB colors. Just give it a try:

import { colorize } from 'acquerello' 
 
console.log(colorize('{{ansi:100}}color me{{-}}')) 
console.log(colorize('{{bgANSI:3,4,5}}color me{{-}}')) 
 
console.log(colorize('{{rgb:255,0,0}}color me{{-}}')) 
console.log(colorize('{{bgRGB:0,255,0}}color me{{-}}')) 
 
console.log(colorize('{{hex:#FF0000}}color me{{-}}')) 
console.log(colorize('{{bgHEX:00FF00}}color me{{-}}'))

ANSI, RGB, and HEX can be used in style definitions and templates as well.

Colorize strings

To colorize strings, simply use the applyStyle, passing a list of styles you want to apply.

import { applyStyle } from 'acquerello' 
 
const inRed = applyStyle('Colorized', 'red') 
const inRedWithBlueBackground = applyStyle('Colorized', 'red bgBlue')
