// The spans will have null for their from/to properties when the
// marker continues beyond the start/end of the line. Markers have
// links back to the lines they currently touch.

/**
* Tag-closer extension for CodeMirror.
*
* This extension adds an "autoCloseTags" option that can be set to
* either true to get the default behavior, or an object to further
* configure its behavior.
*
* These are supported options:
*
* `whenClosing` (default true)
* Whether to autoclose when the '/' of a closing tag is typed.
* `whenOpening` (default true)
* Whether to autoclose the tag when the final '>' of an opening
* tag is typed.
* `dontCloseTags` (default is empty tags for HTML, none for XML)
* An array of tag names that should not be autoclosed.
* `indentTags` (default is block tags for HTML, none for XML)
* An array of tag names that should, when opened, cause a
* blank line to be added inside the tag, and the blank line and
* closing line to be indented.
* `emptyTags` (default is none)
* An array of XML tag names that should be autoclosed with '/>'.
*
* See demos/closetag.html for a usage example.

// apply to the matches. This will be prefixed by "cm-" to create an
// actual CSS class name. If wordsOnly is enabled, the matches will be
// highlighted only if the selected text is a word. showToken, when enabled,
// will cause the current token to be highlighted when nothing is selected.
// delay is used to specify how much time to wait, in milliseconds, before
// highlighting the matches. If annotateScrollbar is enabled, the occurences
// will be highlighted on the scrollbar via the matchesonscrollbar addon.
