javascript code editor [closed]

Question

I need to write a browser-based simple code editor that would highlight errors such as unclosed parentheses, code completion etc.

my question is - which tools would you recommend using to implement this? pure js? gwt?

thanks!

Answer 1

http://codemirror.net/ - Are you are looking for something like this? The editor embedded in the book Eloquent JavaScript was excellent. (CodeMirror is created by Marijn Haverbeke, the author of Eloquent JavaScript)

Answer 2

You should check out Cloud9 IDE ( http://c9.io/ ) which uses Ace. You can also embed Ace in your site ( http://ace.ajax.org/ )

Ace (from Ajax.org Cloud9 Editor) is a standalone code editor written in JavaScript. The goal is to create a web-based code editor that matches and extends the features, usability, and performance of existing native editors such as TextMate, Vim, or Eclipse. It can be easily embedded in any web page and JavaScript application. Ace is developed as the primary editor for Cloud9 IDE and as the successor of the Mozilla Skywriter project.

Features

• Syntax highlighting.
• Auto indentation and outdent.

• Fully customizable key bindings including VI and Emacs modes.
• Themes (TextMate themes can be imported).
• Search and replace with regular expressions.
• Highlight matching parentheses.
• Toggle between soft tabs and real tabs.
