codemirror-composition-mod v5.0.0

CodeMirror Composition Mod for 5.x

When you use IMEs to composite non-latin charaters like Chinese or Japanese, you'll notice that you cannot see the composition text decorated well (usually underlined). You cannot see your cursor moving during compositing either, because the cursor of CodeMirror is a <div> rather than a real cursor.

This add-on tries to enhance the composition experience of CodeMirror for IME users with the Composition Event APIs.

Usage

npm install codemirror-composition-mod --save-dev

link lib/codemirror-composition-mod.css

<link rel="stylesheet" type="text/css" href="lib/codemirror-composition-mod.css" />

require('codemirror-composition-mod')(CodeMirror)
CodeMirror.fromTextArea(el, {
  enableCompositionMod: true
});

Modification to CodeMirror instance

This mod adds 5 additional properties to the CodeMirror instance:

cm.display.inCompositionMode //(Boolean)
cm.display.compositionHead //(Pos)
cm.display.textMarkerInComposition //(TextMarker)
