Gauge honors backpressure and will pause - most writing if it is indicated. -* **options** – *(optional)* An option object. - -Constructs a new gauge. Gauges are drawn on a single line, and are not drawn -if **stream** isn't a tty and a tty isn't explicitly provided. - -If **stream** is a terminal or if you pass in **tty** to **options** then we -will detect terminal resizes and redraw to fit. We do this by watching for -`resize` events on the tty. (To work around a bug in versions of Node prior -to 2.5.0, we watch for them on stdout if the tty is stderr.) Resizes to -larger window sizes will be clean, but shrinking the window will always -result in some cruft. - -**IMPORTANT:** If you previously were passing in a non-tty stream but you still -want output (for example, a stream wrapped by the `ansi` module) then you -need to pass in the **tty** option below, as `gauge` needs access to -the underlying tty in order to do things like terminal resizes and terminal -width detection. - -The **options** object can have the following properties, all of which are -optional: - -* **updateInterval**: How often gauge updates should be drawn, in milliseconds. -* **fixedFramerate**: Defaults to false on node 0.8, true on everything - else. When this is true a timer is created to trigger once every - `updateInterval` ms, when false, updates are printed as soon as they come - in but updates more often than `updateInterval` are ignored. The reason - 0.8 doesn't have this set to true is that it can't `unref` its timer and - so it would stop your program from exiting– if you want to use this - feature with 0.8 just make sure you call `gauge.disable()` before you - expect your program to exit. -* **themes**: A themeset to use when selecting the theme to use. Defaults - to `gauge/themes`, see the [themes] documentation for details. -* **theme**: Select a theme for use, it can be a: - * Theme object, in which case the **themes** is not used. - * The name of a theme, which will be looked up in the current *themes* - object. - * A configuration object with any of `hasUnicode`, `hasColor` or - `platform` keys, which if will be used to override our guesses when making - a default theme selection. - - If no theme is selected then a default is picked using a combination of our - best guesses at your OS, color support and unicode support. -* **template**: Describes what you want your gauge to look like. The - default is what npm uses. Detailed [documentation] is later in this - document. -* **hideCursor**: Defaults to true. If true, then the cursor will be hidden - while the gauge is displayed. -* **tty**: The tty that you're ultimately writing to. Defaults to the same - as **stream**. This is used for detecting the width of the terminal and - resizes. The width used is `tty.columns - 1`. If no tty is available then - a width of `79` is assumed. -* **enabled**: Defaults to true if `tty` is a TTY, false otherwise. If true - the gauge starts enabled. If disabled then all update commands are - ignored and no gauge will be printed until you call `.enable()`. -* **Plumbing**: The class to use to actually generate the gauge for - printing. This defaults to `require('gauge/plumbing')` and ordinarily you - shouldn't need to override this. -* **cleanupOnExit**: Defaults to true. Ordinarily we register an exit - handler to make sure your cursor is turned back on and the progress bar - erased when your process exits, even if you Ctrl-C out or otherwise exit - unexpectedly. You can disable this and it won't register the exit handler. - -[has-unicode]: https://www.npmjs.com/package/has-unicode -[themes]: #themes -[documentation]: #templates - -#### `gauge.show(section | status, [completed])` - -The first argument is either the section, the name of the current thing -contributing to progress, or an object with keys like **section**, -**subsection** & **completed** (or any others you have types for in a custom -template). If you don't want to update or set any of these you can pass -`null` and it will be ignored. - -The second argument is the percent completed as a value between 0 and 1. -Without it, completion is just not updated. You'll also note that completion -can be passed in as part of a status object as the first argument. If both -it and the completed argument are passed in, the completed argument wins. - -#### `gauge.hide([cb])` - -Removes the gauge from the terminal. Optionally, callback `cb` after IO has -had an opportunity to happen (currently this just means after `setImmediate` -has called back.) - -It turns out this is important when you're pausing the progress bar on one -filehandle and printing to another– otherwise (with a big enough print) node -can end up printing the "end progress bar" bits to the progress bar filehandle -while other stuff is printing to another filehandle. These getting interleaved -can cause corruption in some terminals. - -#### `gauge.pulse([subsection])` - -* **subsection** – *(optional)* The specific thing that triggered this pulse - -Spins the spinner in the gauge to show output. If **subsection** is -included then it will be combined with the last name passed to `gauge.show`. - -#### `gauge.disable()` - -Hides the gauge and ignores further calls to `show` or `pulse`. - -#### `gauge.enable()` - -Shows the gauge and resumes updating when `show` or `pulse` is called. - -#### `gauge.isEnabled()` - -Returns true if the gauge is enabled. - -#### `gauge.setThemeset(themes)` - -Change the themeset to select a theme from. The same as the `themes` option -used in the constructor. The theme will be reselected from this themeset. - -#### `gauge.setTheme(theme)` - -Change the active theme, will be displayed with the next show or pulse. This can be: - -* Theme object, in which case the **themes** is not used. -* The name of a theme, which will be looked up in the current *themes* - object. -* A configuration object with any of `hasUnicode`, `hasColor` or - `platform` keys, which if will be used to override our guesses when making - a default theme selection. - -If no theme is selected then a default is picked using a combination of our -best guesses at your OS, color support and unicode support. - -#### `gauge.setTemplate(template)` - -Change the active template, will be displayed with the next show or pulse - -### Tracking Completion - -If you have more than one thing going on that you want to track completion -of, you may find the related [are-we-there-yet] helpful. It's `change` -event can be wired up to the `show` method to get a more traditional -progress bar interface. - -[are-we-there-yet]: https://www.npmjs.com/package/are-we-there-yet - -### THEMES - -``` -var themes = require('gauge/themes') - -// fetch the default color unicode theme for this platform -var ourTheme = themes({hasUnicode: true, hasColor: true}) - -// fetch the default non-color unicode theme for osx -var ourTheme = themes({hasUnicode: true, hasColor: false, platform: 'darwin'}) - -// create a new theme based on the color ascii theme for this platform -// that brackets the progress bar with arrows -var ourTheme = themes.newTheme(themes({hasUnicode: false, hasColor: true}), { - preProgressbar: '→', - postProgressbar: '←' -}) -``` - -The object returned by `gauge/themes` is an instance of the `ThemeSet` class. - -``` -var ThemeSet = require('gauge/theme-set') -var themes = new ThemeSet() -// or -var themes = require('gauge/themes') -var mythemes = themes.newThemeSet() // creates a new themeset based on the default themes -``` - -#### themes(opts) -#### themes.getDefault(opts) - -Theme objects are a function that fetches the default theme based on -platform, unicode and color support. - -Options is an object with the following properties: - -* **hasUnicode** - If true, fetch a unicode theme, if no unicode theme is - available then a non-unicode theme will be used. -* **hasColor** - If true, fetch a color theme, if no color theme is - available a non-color theme will be used. -* **platform** (optional) - Defaults to `process.platform`. If no - platform match is available then `fallback` is used instead. - -If no compatible theme can be found then an error will be thrown with a -`code` of `EMISSINGTHEME`. - -#### themes.addTheme(themeName, themeObj) -#### themes.addTheme(themeName, [parentTheme], newTheme) - -Adds a named theme to the themeset. You can pass in either a theme object, -as returned by `themes.newTheme` or the arguments you'd pass to -`themes.newTheme`. - -#### themes.getThemeNames() - -Return a list of all of the names of the themes in this themeset.

If your theme is platform - specific, specify that here with the platform from `process.platform`, eg, - `win32`, `darwin`, etc. -* **hasUnicode** - Defaults to `false`. If your theme uses unicode you - should set this to true. -* **hasColor** - Defaults to `false`. If your theme uses color you should - set this to true. - -`themeName` is the name of the theme (as given to `addTheme`) to use for -this set of `opts`. - -#### themes.newTheme([parentTheme,] newTheme) - -Create a new theme object based on `parentTheme`. If no `parentTheme` is -provided then a minimal parentTheme that defines functions for rendering the -activity indicator (spinner) and progress bar will be defined. (This -fallback parent is defined in `gauge/base-theme`.) - -newTheme should be a bare object– we'll start by discussing the properties -defined by the default themes: - -* **preProgressbar** - displayed prior to the progress bar, if the progress - bar is displayed. -* **postProgressbar** - displayed after the progress bar, if the progress bar - is displayed. -* **progressBarTheme** - The subtheme passed through to the progress bar - renderer, it's an object with `complete` and `remaining` properties - that are the strings you want repeated for those sections of the progress - bar. -* **activityIndicatorTheme** - The theme for the activity indicator (spinner), - this can either be a string, in which each character is a different step, or - an array of strings. -* **preSubsection** - Displayed as a separator between the `section` and - `subsection` when the latter is printed. - -More generally, themes can have any value that would be a valid value when rendering -templates. The properties in the theme are used when their name matches a type in -the template. Their values can be: - -* **strings & numbers** - They'll be included as is -* **function (values, theme, width)** - Should return what you want in your output. - *values* is an object with values provided via `gauge.show`, - *theme* is the theme specific to this item (see below) or this theme object, - and *width* is the number of characters wide your result should be. - -There are a couple of special prefixes: - -* **pre** - Is shown prior to the property, if its displayed. -* **post** - Is shown after the property, if its displayed. - -And one special suffix: - -* **Theme** - Its value is passed to a function-type item as the theme. - -#### themes.addToAllThemes(theme) - -This *mixes-in* `theme` into all themes currently defined. It also adds it -to the default parent theme for this themeset, so future themes added to -this themeset will get the values from `theme` by default. - -#### themes.newThemeSet() - -Copy the current themeset into a new one. This allows you to easily inherit -one themeset from another. - -### TEMPLATES - -A template is an array of objects and strings that, after being evaluated, -will be turned into the gauge line. The default template is: - -```javascript -[ - {type: 'progressbar', length: 20}, - {type: 'activityIndicator', kerning: 1, length: 1}, - {type: 'section', kerning: 1, default: ''}, - {type: 'subsection', kerning: 1, default: ''} -] -``` - -The various template elements can either be **plain strings**, in which case they will -be be included verbatum in the output, or objects with the following properties: - -* *type* can be any of the following plus any keys you pass into `gauge.show` plus - any keys you have on a custom theme. - * `section` – What big thing you're working on now. - * `subsection` – What component of that thing is currently working. - * `activityIndicator` – Shows a spinner using the `activityIndicatorTheme` - from your active theme. - * `progressbar` – A progress bar representing your current `completed` - using the `progressbarTheme` from your active theme. -* *kerning* – Number of spaces that must be between this item and other - items, if this item is displayed at all. -* *maxLength* – The maximum length for this element. If its value is longer it - will be truncated. -* *minLength* – The minimum length for this element. If its value is shorter it - will be padded according to the *align* value. -* *align* – (Default: left) Possible values "left", "right" and "center". Works - as you'd expect from word processors. -* *length* – Provides a single value for both *minLength* and *maxLength*. If both - *length* and *minLength or *maxLength* are specified then the latter take precedence. -* *value* – A literal value to use for this template item. -* *default* – A default value to use for this template item if a value - wasn't otherwise passed in. - -### PLUMBING - -This is the super simple, assume nothing, do no magic internals used by gauge to -implement its ordinary interface. - -``` -var Plumbing = require('gauge/plumbing') -var gauge = new Plumbing(theme, template, width) -``` - -* **theme**: The theme to use. -* **template**: The template to use. -* **width**: How wide your gauge should be - -#### `gauge.setTheme(theme)` - -Change the active theme. - -#### `gauge.setTemplate(template)` - -Change the active template. - -#### `gauge.setWidth(width)` - -Change the width to render at. - -#### `gauge.hide()` - -Return the string necessary to hide the progress bar - -#### `gauge.hideCursor()` - -Return a string to hide the cursor. - -#### `gauge.showCursor()` - -Return a string to show the cursor. - -#### `gauge.show(status)` - -Using `status` for values, render the provided template with the theme and return -a string that is suitable for printing to update the gauge. |
