# electron-editor-context-menu

In Electron, right-clicking in text editors does… nothing.

This module enables the menu you'd expect, with optional
[spell-checker integration][spell-checker integration].

## Installation

```js
npm install electron-editor-context-menu
```
or
```js
npm install electron-editor-context-menu --save
```

## Usage

```js
// In the renderer process:
var remote = require('electron').remote;
// `remote.require` since `Menu` is a main-process module.
var buildEditorContextMenu = remote.require('electron-editor-context-menu');

window.addEventListener('contextmenu', function(e) {
  // Only show the context menu in text editors.
  if (!e.target.closest('textarea, input, [contenteditable="true"]')) return;

var menu = buildEditorContextMenu();

// The 'contextmenu' event is emitted after 'selectionchange' has fired but possibly before the
  // visible selection has changed. Try to wait to show the menu until after that, otherwise the
  // visible selection will update after the menu dismisses and look weird.
  setTimeout(function() {
    menu.popup(remote.getCurrentWindow());
  }, 30);
});
```

### Spell-checker integration

Show spelling suggestions by passing a _selection_ object when building the menu:

```js
var selection = {
  isMisspelled: true,
  spellingSuggestions: [
    'men',
    'mean',
    'menu'
  ]
};

var menu = buildEditorContextMenu(selection);
```

Get these suggestions when your [spell-check provider][setSpellCheckProvider] runs
&mdash;Electron will poll it immediately before the `'contextmenu'` event fires.

For a complete example using `electron-spell-check-provider`, see
[here][spell-checker integration example].

### Customizing the menu

You can add or remove items to the menu, or replace it entirely, by providing
`mainTemplate` and/or `suggestionsTemplate` parameters when building the menu:

```js
var menu = buildEditorContextMenu(selection, mainTemplate, suggestionsTemplate);
```

The `mainTemplate` parameter customizes the always-present menu items; the
`suggestionsTemplate` parameter customizes the spelling suggestion items.
Pass an array of items to replace the default items entirely; pass a function
to add/remove/edit the default items. The function will be passed the default
array of items as a parameter and should return an array of items.
