阅读更多关于 Autocompletion in ACE editor

I've found simmilar question: Ace Editor autocomplete and multiple languages But the responses were that autocompletion is not supported by ACE, and according to Google group for Ace Editor "It is on my wishlish for Ace and we definitively need it for Cloud9". This post is one year old and as you can see, the cloud9 supports autocompletion now: https://c9.io/site/features/ So is autocompletion available in Ace Editor by default? I cannot find any information about it. Autocomplete is now an official part of the API. Enabling it takes 3 lines of code: ace.require("ace/ext/language_tools"); var

Automatically adjust height to contents in Ace Cloud 9 editor

阅读更多关于 Automatically adjust height to contents in Ace Cloud 9 editor

I'm trying to add the Ace editor to a page, but I don't know how to get the height to be set automatically based on the length of its contents. Ideally it would work so when the content changes the height is recalculated, but I would be happy with the height just being set on page load. For a JavaScript novice can someone help me figure out how I work out the length of the code, how many lines it spans, what the new height is and how I update the DOM to reflect this? I found this suggestion in a Google group, but I don't really understand what it's doing and how I get it to adjust the height.

As far as I understood the idea of Ace, you shouldn't make a textarea an Ace editor itself. You should create an additional div and update textarea

问题 I've found the beautify extension in Ace editor but I don't see any examples of how to use it. Here's what I have so far: var beautiful = ace.require("ace/ext/beautify"); beautiful.beautify(); but I get the error: Result of expression 'e' [undefined] is not an object. 回答1: It looks like this works: var beautify = ace.require("ace/ext/beautify"); // get reference to extension var editor = ace.edit("editor"); // get reference to editor beautify.beautify(editor.session); It requires that you

问题 Totally new to ace editor dev, to dynamically add additional rules to a mode file for syntax highlighting I'm doing an ajax call that sets a global variable that is available inside the mode file to process.
