var createPanel = require('settings-panel')

var panel = createPanel([
  {type: 'range', label: 'my range', min: 0, max: 100, value: 20},
  {type: 'range', label: 'log range', min: 0.1, max: 100, value: 20, scale: 'log'},
  {type: 'text', label: 'my text', value: 'my cool setting', help: 'why this is cool'},
  {type: 'checkbox', label: 'my checkbox', value: true},
  {type: 'color', label: 'my color', format: 'rgb', value: 'rgb(10,200,0)', change: value => console.log(value)},
  {type: 'button', label: 'gimme an alert', change: () => alert('hello!')},
  {type: 'select', label: 'select one', options: ['option 1', 'option 2'], value: 'option 1'}
],
  {
    title: 'Settings',
    style: 'position: absolute; right: 0; z-index: 1'
  }
);

API

const Panel = require('settings-panel')

**`let panel = new Panel(fields, options?)`**

The first argument is a list of fields or object with id/field pairs. Each field may have following properties:

• type one of range • interval • checkbox • color • select • switch • raw • textarea • text or any <input> type. If undefined, type will be detected from the value.
• id used as key to identify the field. If undefined, the label will be used instead.
• label label for the input. If label is false, it will be hidden.
• value current value of the field.
• default explicitly defines default value, if differs from the initial value.
• orientation defines position of a label relative to the input, one of top, left, right, bottom. Redefines options.orientation.
• style appends additinal style to the field, can be a css object or css string.
• hidden defines whether field should be visually hidden, but present as a value.
• disabled just disables the input, making it inactive.
• input callback, invoked if value changed.
• init invoked once component is set up.
• change invoked each time the field value changed, whether through input or API.
• before and after define an html to display before or after the element, can be a string, an element or a function returning one of the two. That may come handy in displaying help, info or validation messages, separators, additional buttons, range limits etc - anything related to the element.
• title will display text in tooltip.

For example,

{type: 'checkbox', label: 'My Checkbox', value: true, input: value => {}}

Some types have additional properties:

• range can specify a min, max, and step (or integer steps). Scale can be either 'linear' (default) or 'log'. If a log scale, the sign of min, max, and value must be the same and only steps is permitted (since the step size is not constant on a log scale). It also takes precision optional parameter for the displayed value.
• interval obeys the same semantics as range inputs, except the input and ouput is a two-element array corresponding to the low/high bounds, e.g. value: [1, 7.5].
• color can specify a format as either rgb • hex • array
• select, switch and checkbox can specify options, either as an Array (in which case the value is the same as the option text) or as an object containing key/value pairs (in which case the key/value pair maps to value value/label pairs).
• text and textarea can specify placeholder.
• raw can define content method, returning HTML string, element or documentFragment.

container: document.body,

**`panel.on(event, callback)`**

Attach callback to change, input or init event.

The callback will recieve name, data and state arguments:

panel.on('change', (name, value, state) => {
  // name === 'my checkbox'
  // value === false
  // state === {'my checkbox': false, 'my range': 75, ...}
});

**`panel.get(name?)`**

Get the value of a field defined by name. Or get full list of values, if name is undefined.

**`panel.set(name, value|options)`**

Update specific field, with value or field options. You can also pass an object or array to update multiple fields:

panel.set({ 'my range': { min: -100, value: 200}, 'my color': '#fff' });

**`panel.update(options?)`**

Rerender panel with new options. Options may include values for the theme, like palette, fontSize, fontFamily, labelWidth, padding etc, see specific theme file for possible options.
