34 <p>CodeMirror is a code-editor component that can be embedded in Web pages. The core library provides <em>only</em> the editor component, no accompanying buttons, auto-completion, or other IDE functionality. It does provide a rich API on top of which such functionality can be straightforwardly implemented. See the <a href="#addons">add-ons</a> included in the distribution, and the <a href="https://github.com/jagthedrummer/codemirror-ui">CodeMirror UI</a> project, for reusable implementations of extra features.</p> | |
35 | |
36 <p>CodeMirror works with language-specific modes. Modes are JavaScript programs that help color (and optionally indent) text written in a given language. The distribution comes with a number of modes (see the <a href="../mode/"><code>mode/</code></a> directory), and it isn't hard to <a href="#modeapi">write new ones</a> for other languages.</p> | |

40 <p>This page uses a hack on top of the <code>"renderLine"</code> | |
41 event to make wrapped text line up with the base indentation of | |
42 the line.</p> | |
43 | |
44 <script> | |
45 var editor = CodeMirror.fromTextArea(document.getElementById("code"), { | |
46 lineNumbers: true, | |
47 lineWrapping: true, | |
48 mode: "text/html" | |
49 }); | |
50 var charWidth = editor.defaultCharWidth(), basePadding = 4; | |
51 editor.on("renderLine", function(cm, line, elt) { | |
52 var off = CodeMirror.countColumn(line.text, null, cm.getOption("tabSize")) * charWidth; | |
53 elt.style.textIndent = "-" + off + "px"; | |
54 elt.style.paddingLeft = (basePadding + off) + "px"; | |
55 }); | |
56 editor.refresh(); | |
