There are tons of sublime plugins available. Even though I was working with just a simple textarea at this point, this was already a bit of a headache. Because of this, writing such applications, when it is even possible, is painful process.

However, when applications go sufficiently beyond the things that browsers were designed for, the available APIs do not give enough control, are nonstandard and buggy, and are often poorly designed.

Features of the code editor

The code will be represented by some kind of DOM tree. For more information about hotkeys, see Default keyboard shortcuts. Just like VS Code, it is also extensible through plugins and supports many IDE-like features which can increase your speed and efficiency when writing code.

In the end I came to the conclusion that I only needed two operations: Continuation passing style was a good way to model this process in an iterator, which has to be processed one step at a time.

Basically, the good folks at Microsoft designed a really bad interface for putting editable documents in pages, and the other browsers, not wanting to be left behind, more or less copied that. This is horribly clunky though, especially considering the fact that modern JavaScripters often put all the code in a file in a single big object or function to prevent namespace pollution.

This meant automatic indentation and, if possible at all, syntax highlighting. Text editor plays the primary role in any developer workspace. Regarding custom shaders, AFAIK the support was dropped in Chrome due to many issues with performances and hit test of altered elements.

I don't consider myself a JavaScript rookie anymore, but it was embarrasingly enough only this week that I realized that my habit of typing for name in object Maybe something like Silverlight or whatever other new browser plugin gizmos people are pushing these days will become the way to solve things like this in the future.

I wanted to 'enhance' a textarea to the point where writing code in it is pleasant. Since the text inside a textarea can only be manipulated as one single big string, I had to spread it out over multiple nodes. The first lines of scanNode extend the continuation with the task of scanning the next node, if there is a next node.

The plan was not ridiculously ambitious. Finding the top-level node around or before the cursor, to mark it dirty or to insert indentation whitespace at the start of that line. This text appears when the user types help. Libraries like Dojo and a similar monster I once wrote myself even make complex, composite widgets workable.

Vim is extremely popular among developers and other computer enthusiasts who seek an entirely customizable text editor.
