// CodeMirror, copyright (c) by Marijn Haverbeke and others // Distributed under an MIT license: https://codemirror.net/5/LICENSE // Highlighting text that matches the selection // // Defines an option highlightSelectionMatches, which, when enabled, // will style strings that match the selection throughout the // document. // // The option can be set to true to simply enable it, or to a // {minChars, style, wordsOnly, showToken, delay} object to explicitly // configure it. minChars is the minimum amount of characters that should be // selected for the behavior to occur, and style is the token style to // 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 occurrences // will be highlighted on the scrollbar via the matchesonscrollbar addon.
