const cholk = Cholk()
cholk.red.bold.underline('Hello ', 'World').gap.blue.underline('Hello ', 'Cholk')
console.log(...cholk)

cholk.red('Hello ').reset('Cholk')
console.log(...cholk)

cholk.values()

const cholk = Cholk()
cholk.red('Hello ')('Cholk')
console.log(cholk.values()) // return [template, ...params]
console.log(...cholk) // consume the values
console.log(cholk.values()) // empty values -> []

Static method

Cholk.styles()

const styles = Cholk.styles()
console.log(styles)

Cholk.extend(config)

config: {
   colors: {
     [CholkColorName]: CholkCssValue  // accept css color value
   },
   styles: {
     [CholkStyleName]: CholkCssValue // css rules
   },
   baseStyle: CholkColorName | CholkStyleName | CholkCssValue | [CholkColorName | CholkStyleName | CholkCssValue, ...]
   preset: {
     [CholkFuncName]: {
       css: CholkColorName | CholkStyleName | CholkCssValue | [CholkColorName | CholkStyleName | CholkCssValue, ...],
       log: CholkLogValue | [CholkLogValue, ...] | (...args) => CholkLogValue
     }
   },
}

Example:

Cholk.extend({
  colors: {
    lightDark: 'rgb(96, 96, 96)',
    lightGreen: 'rgb(71, 193, 25)',
  },
  styles: {
    pad: 'padding: 3px 8px;',
    tag: 'color: rgb(255, 244, 208);',
    radiusLeft: 'border-top-left-radius: 3px;border-bottom-left-radius: 3px;',
    radiusRight: 'border-top-right-radius: 3px;border-bottom-right-radius: 3px;',
  },
  baseStyle: 'pad',
  preset: {
    tag: {
      css: ['tag', 'bgLightDark'],
      log: (...args) => {
        return ['Cholk', ...args]
      },
    },
    tagSuccess: {
      css: ['tag', 'bgLightGreen'],
      log: (...args) => {
        return args
      },
    },
    tagError: {
      css: ['tag', 'bgRed'],
      log: (...args) => {
        return ['Error', ...args]
      },
    },
  },
})
const values = cholk.tag(' v1.0.0').tagSuccess('100% ').tagError().values()
console.log(values)
console.log(...cholk)
console.log(...cholk.radiusLeft.tag(' v1.0.0').radiusRight.tagSuccess('100%%').tagError()) // use `%%` to escape `%`
console.log(...cholk.tagSuccess('100%'))
console.log(...cholk.tagError().reset.gap('something wrong'))

Hints

Be careful of %

console.log('%s%s', 'String Specifier is `%s`, ', 'it formats the value as a string')
// expects: "String Specifier is `%s`, it formats the value as a string"
// actually: "String Specifier is `it formats the value as a string`, %s"

Exactly:

// use `%%` to escape `%` in strings
console.log('%s%s', 'String Specifier is `%%s`, ', 'it formats the value as a string')
// => String Specifier is `%s`, it formats the value as a string

nil vs reset

With baseStyle

import Cholk from 'web-cholk'

Cholk.extend({
  baseStyle: 'padding: 4px 8px; border: 1px solid #888;',
})

const cholk = Cholk()

const cholkValues = cholk.red('Red')('Normal').values()
console.log(cholkValues)
console.log(...cholk)

// nil() => just append a empty style `;`, use as a style separator
const cholkNilValues = cholk.red('Red').nil('Nil').values()
console.log(cholkNilValues)
console.log(...cholk)

// reset() => replace styles with empty style `;`, use to clear baseStyle
const cholkResetValues = cholk.red('Red').reset('Reset').values()
console.log(cholkResetValues)
console.log(...cholk)

without baseStyle

import Cholk from 'web-cholk'

Cholk.extend({
  baseStyle: '',
})

const cholk = Cholk()

const cholkValues = cholk.red('Red')('Normal').values()
console.log(cholkValues)
console.log(...cholk)

// nil() => just append a empty style `;`, use as a style separator
const cholkNilValues = cholk.red('Red').nil('Nil').values()
console.log(cholkNilValues)
console.log(...cholk)

// reset() => replace styles with empty style `;`, use to clear baseStyle
const cholkResetValues = cholk.red('Red').gap.reset('Reset').values()
console.log(cholkResetValues)
console.log(...cholk)
