Append template option to templates plugin

[Matti Järvinen]

Proposal for templates plugin expansion for adding an option to append selected template into editor data.

Sometimes and especially with responsive web design it would be very helpful if templates plugin would have an option to append selected template into editor HTML instead of just replacing whole content with a template or inserting template into cursor position.

Quick prototype solution below.

templates/dialogs/templates.js

function insertTemplate( html ) {
	var dialog = CKEDITOR.dialog.getCurrent(),
		replaceType = dialog.getValueOf( 'selectTpl', 'chkInsertOpt' );

	switch(replaceType)
	{
		case 'append':
			
			editor.fire( 'saveSnapshot' );
			// Everything should happen after the document is loaded (#4073).
			
			var currentHTML = editor.getData( );
			
			editor.setData( currentHTML + html, function() {
				dialog.hide();

				// Place the cursor at the first editable place.
				var range = editor.createRange();
				range.moveToElementEditStart( editor.editable() );
				range.select();
				setTimeout( function() {
					editor.fire( 'saveSnapshot' );
				}, 0 );

			} );
			
			break;
		case 'replace':
			
			editor.fire( 'saveSnapshot' );
			// Everything should happen after the document is loaded (#4073).
			editor.setData( html, function() {
				dialog.hide();

				// Place the cursor at the first editable place.
				var range = editor.createRange();
				range.moveToElementEditStart( editor.editable() );
				range.select();
				setTimeout( function() {
					editor.fire( 'saveSnapshot' );
				}, 0 );

			} );
			
			break;
			
		case 'in-place':
		default:
			
			editor.insertHtml( html );
			dialog.hide();
			
			break;
	}
}

templates/dialogs/templates.js dialog definition.

{
	id: 'chkInsertOpt',
	type: 'select',
	label: lang.insertOption,
	style: 'width:100%',
	'default': config.templates_replaceContent,
	items: [
	[ 'append' ],
	[ 'in-place' ],
	[ 'replace' ]
	]
}

@matti extending existing plugin to append data at the end (or start - this can be also added) of document sounds interesting.

To get your proposed fix/feature tested and applied (if it is correct) please fork CKEditor 4 code from ​https://github.com/ckeditor/ckeditor-dev, prepare your fix and make a "pull request" (here is the example list of pull requests ​https://github.com/ckeditor/ckeditor-dev/pulls?direction=desc&page=1&sort=created&state=open). In comment please specify link to bug for which this fix was prepared. This is much faster way to get proposed fix/feature implemented/rejected (if they are invalid). At least in V4.
