Default `" [:bar] :current/:total :percent :elapseds :etas'"`. - `total` - total number of ticks to complete. Default `100`. - `current`- number of completed ticks. Default `0`. - `width` - display width, percentage or less than `1` is relative the terminal's width. Default `60`. - `fixedWidth` - do not adjust the bar based on the terminal size - `filled`- completion character. Default `"▇"`. - `blank` - blank character. Default `"-"`. - `clean` - clear the progress bar on completion. Default `false`. - `callback` - optional function to call when the progress bar completes. ### Properties - `schema` - `total` - `current` - `completed` ### Methods - `setSchema(schema, refresh/tokens)` - Update the schema of the progress bar. If `refresh` or `tokens` is truely the progress bar will be refreshed. - `tick(delta, tokens)` - Update ticks of the progress bar by `delta`, then render the progress bar with optional `tokens`. - `update(ratio, tokens)` - Update the progress bar to `ratio` by percentage, then render the progress bar with optional `tokens`. - `clear()` - Clean the progress bar in the terminal. ## Schema The schema defines appearance the progress bar. Few inner tokens and many formatting methods can be used to customer you progress bar. ### Tokens These are tokens you can use in the format of your progress bar. - `:filled` Completed part of the progress bar. - `:blank` Blank part of the progress bar. - `:bar` Whole progress bar, equal to `:completed:blank`. - `:current` Current tick number. - `:total` Total ticks. - `:percent` Completion percentage. - `:elapsed` Time elapsed in seconds. - `:eta` Estimated completion time in seconds. ### Custom Tokens You can define custom tokens by adding a `{name: value}` object parameter to your method (`tick()`, `update()`, etc.) calls. ```javascript const bar = new ProgressBar({ schema: ':current: :token1 :token2', total : 3, }); bar.tick({ 'token1': "Hello", 'token2': "World!" }) bar.tick(2, { 'token1': "Goodbye", 'token2': "World!" }) ``` The above example would result in the output below. ``` 1: Hello World! 3: Goodbye World! ``` ### Colors Color names can be use in schema: ``` :bar.red :percent.green ``` Then the progress bar will be red, and the percentage will be green. All available color names: - red - cyan - blue - grey - white - black - green - yellow - magenta - brightRed - brightBlue - brightCyan - brightWhite - brightBlack - brightGreen - brightYellow - brightMagenta And with the `bg` prefix, such as `bgRed`, the color will be applied to the background. ``` :bar.red.bgBlue ``` The above progress bar has blue background and red foreground. ### Gradient ``` :bar.gradient(red,blue) ``` The arguments can be color names or hex color: - red - cyan - blue - grey - white - black - green - yellow - magenta - \#xxxxxx ### Font style Same as color names, font style can also be assigned by name: - bold - italic - inverse - underline ``` :bar.red :percent.green.bold ``` The percentage is green and bold. ## Contributing Please let us know how can we help.
