class

Printer

Printer: render any value to text.

class MMO.core.Printer

Espace de noms: MMO.core

Use Shared instance: Printer try every renderer corresponding to the given format (opts.format), or the given types (opts.type)

render something: MMO.core.Printer.Shared().render(value); add a new renderer: MMO.core.Printer.Shared().setRenderer('datetime', (value, opts) => ...);

MMO.core.Printer.Shared().render(false, {format: status, type: [null]}) This will cause the printer to try the following renderder: 'status', 'null', 'boolean' (from typeof value). If any renderer exists and returns a string or an Element, the printer will stop trying other renderer.

constructor()

Shared(id)

staticPrinter.js:27

Get a shared printer, creating it (with the default renderers) on first use.

static Shared(id = '*')

id = '*'	`string`	keep several independent printers side by side
retourne	MMO.core.Printer

EntityNames(entries)

staticPrinter.js:44

The name each entity of a list is shown by: its title, unless another entity of the same list has that title too (two establishments named « SIEGE - Courbevoie »): each of those also shows its label, what tells it apart, less the - parts its end shares with the title -- « SIEGE - Courbevoie (TRANSLOGIX Transport) » for the label « TRANSLOGIX Transport - Courbevoie » (my.oviepro #209). A label that tells nothing more adds nothing.

static EntityNames(entries)

entries	`Array`	a list's entries: those that are not an MMO.elements.Entity are ignored
retourne	`Map`	MMO.elements.Entity => the name to show

setRenderer(format, fn, opts)

Printer.js:71

setRenderer(format, fn, opts = [])

format	`string`	a format name, a json type, or a `typeof` result
fn	`Function`	function(value, opts): string\|Element\|Array\|null\|false return null or false to decline the value and let the next renderer try
opts = []	`Object`	options merged into every call's `opts`

getRenderer(format)

Printer.js:79

getRenderer(format)

format	`string`
retourne	`?Function`	null when nothing is registered

callRenderer(type, value, opts)

Printer.js:90

Run one renderer, without the format/type resolution MMO.core.Printer#render does.

callRenderer(type, value, opts)

type	`string`	the renderer's name
value	`*`
opts	`Object`
retourne	`string` \| `Element` \| `Array` \| `false`	false when the renderer is missing or declined

getOptions(format)

Printer.js:104

getOptions(format)

format	`string`
retourne	`?Object`	null when nothing is registered under that name

setOptions(format, opts)

Printer.js:114

Replace a registered renderer's options.

setOptions(format, opts)

format	`string`
opts	`Object`
lève	`MMO.Error`	when nothing is registered under that name

render(value, opts)

Printer.js:126

Render a value, trying the renderers in order until one accepts it: opts.format, then each of opts.type, then typeof value.

render(value, opts = [])

value	`*`
opts = []	`Object`	`format`, `type`, `html` and whatever the renderer reads
retourne	`string` \| `Element` \| `Array`	the value stringified when no renderer matched

setDefaultRenderers()

Printer.js:162

renderHeader(headerProperties, key) { if (headerProperties.contentRoot instanceof MMO.core.Map) { headerProperties = headerProperties.contentRoot.toObject(); } const currentHeader = headerProperties[key]; if (!currentHeader.headerFormat) { return currentHeader.title; } return this.callRenderer(currentHeader.headerFormat, currentHeader); }
