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.
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.
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 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.
By default, Solution Explorer shows your code organized by files. Then when you press the preview button to see what the blog post looks like, no styling has been applied to the codeblock text because prism.
They are not displayed by default. View White Space Displays spaces as raised dots, and tabs as arrows.
For more information, see Find and replace text. At the end of the function, the current variable set is 'popped' off and the previous one is restored. When the function that copy produces is called with a token stream as argument, it updates the local variables in the parser closure, and returns the corresponding iterator object.
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.
Syntax highlighting for multiple programming and scripting languages is one of the most useful tools in any text editor, and autocomplete is a welcome addition as well. I am building a text editor using an iframe as the editor. I'm working on a menu item that when clicked, allows the user to write a block of code that is then styled using the Prism syntax highlighter, and added inside the iframe with the rest of the text content.
