Can Ace Editor support multiple code editors in one page?

Question

I'm looking to implement a web app that features "coding-competition"-styled interface with 2 different code editors in a single screen. One will be read only and the other will be active and would allow the user to edit.

I'm currently using Ace Editor and i find it awesome and simple to use.

However, here's my question. I seem to be getting an error upon trying to implement 2 different editors in a single page.

Uncaught RangeError: Maximum call stack size exceeded

Is the variable "editor" in the js script a restricted word or it doesn't matter what variable name is used?

Here's my code in my JS file:

var editorFirst = ace.edit("editorFirst");
var editorSecond= ace.edit("editorSecond");
setupEditor();

function setupEditor() {
    editorFirst.setTheme("ace/theme/eclipse");
    editorFirst.getSession().setMode("ace/mode/javascript");
    editorFirst.setShowPrintMargin(false);
    editorFirst.setHighlightActiveLine(true);
    editorFirst.resize();
    editorFirst.setBehavioursEnabled(true);
    editorFirst.getSession().setUseWrapMode(true);
    document.getElementById('editorFirst').style.fontSize = '14px';

    editorSecond.setTheme("ace/theme/eclipse");
    editorSecond.getSession().setMode("ace/mode/javascript");
    editorSecond.setShowPrintMargin(false);
    editorSecond.setHighlightActiveLine(true);
    editorSecond.resize();
    editorSecond.setBehavioursEnabled(true);
    editorReducer.getSession().setUseWrapMode(true);
    document.getElementById('editorSecond').style.fontSize = '14px';
}

Here's my code for the html file:

<script src="../assets/js/main.js"></script>
<script src="../assets/js/src/ace.js" type="text/javascript" charset="utf-8"></script>
<div id="editorFirst"></div>
<div id="editorSecond"></div>

Thanks in advance for the replies!

Answer 1

Ace can support any number of editors. The problem is recent regression which breaks resize for editors with height=0 see this demo

Answer 2

What I did was instead of using the id editor I set it as a class so code Then I just iterated every editor.

var editor;
$('.editor').each(function( index ) {
  editor = ace.edit(this);
  editor.getSession().setMode('ace/mode/csharp');
});

Answer 3

Yes it can support. Look at my example http://jsfiddle.net/igos/qLAvN/

$(function() {
    var editor1 = ace.edit("editor1");
    editor1.getSession().setMode("ace/mode/java");

    var editor2 = ace.edit("editor2");
    var editor3 = ace.edit("editor3");
    $( "#accordion" ).accordion({
        fillSpace: true,
        change: function() {
            $(editor1).resize(); 
            $(editor2).resize(); 
            $(editor3).resize(); 
        }
        });
});

This method can make ulimited ace editor:

<pre class='editor' data-name='editor_1' id='editor_1'></pre>
<input  name='editor_1' type='hidden' value='' />

<pre class='editor' data-name='editor_2' id='editor_2'></pre>
<input  name='editor_2' type='hidden' value='' />

<pre class='editor' data-name='editor_3' id='editor_3'></pre>
<input  name='editor_3' type='hidden' value='' />


<script type="text/javascript">

$(document).ready(function(){

ace.require("ace/ext/language_tools");
var editor;
var ednum = 0;
ace_config = {
    maxLines: Infinity,
    enableBasicAutocompletion: true,
    enableSnippets: true,
    enableLiveAutocompletion: false
};

$('.editor').each(function( index ) {
    ednum++;
    _name = "editor_"+ednum;
    code = "var name = $(this).data('name');"
    +_name+" = ace.edit(this);"
    +_name+".setTheme('ace/theme/chrome');"
    +_name+".getSession().setMode('ace/mode/less');"
    +_name+".setOptions(ace_config);"
    +"var code_"+ednum+" = $('textarea[name='+name+']');"
    +_name+".getSession().setValue($('input[name='+name+']').val());"
    +_name+".getSession().on('change', function(){"
    +"$('input[name='+name+']').val("+_name+".getSession().getValue());"
    +"});";
    eval(code);

});

</script>
