You gave-me a good idea. I´ll check how much chars the textfield can do the parse
without loose performance, so that will be limit of my script.

That means that on every stroke the player has to reparse the entire htmlText, recreate all the style runs, and redo all the line wrapping based on new measurement. No matter how fast the Player got, that design wouldn't scale to arbitrarily large documents.

Yes, i´m trying to do a code editor. Since it´s just for learn purpose, 3000 chars is ok,
but would be nice support normal file size.

I didn´t try replace/setTextFormat. What I do is every stroke, parse the text property and
generate an html wich I set to htmlText.

I don´t know how to do a highligher that can work with fragments of text, what would be much faster.
My highlighter is a mix of tokenizer and regular _expression_. I´m doing a benchmark class to
analyze where are the bottle necks on my algorithm.

Can you shed more light on what you are trying to do?  Is it something like a code editor where as you type it colors certain text in certain ways?

 

Have you tried using replaceSelectedText()/replaceText() instead?  Have you tried using setTextFormat()?

I really set text property each textChange event. I couldn´t think a better solution.

I would revisit your highlighting algorithm.  If you set the .text property too often it will definitely slow things down.

One limitation of Flash player is speed. I´m doing a sintaxe highlighter but
with a text bigger than 3000 chars, the input became slow in my machine that is
an Athlon 64 3GHz with 1GB ram!!!

I don't think I said it would but, just that there are things that the flash player can do that can work around current barriers.

Peace, Mike

Yes, but I don't know if this will ever be out in the public. However, we know it is possible to make a very advanced text editor, rivalling desktop editors. Flash is ready, but it is just a hell of a lot of work.

 Thanks Claus :), yes Stefan we are talking about something REAL. All I am saying is be an engineer - inventor, don't limit yourself to what you think you can do, try to do what you can't do.

Peace, Mike

It's not online yet afaik. But just in case you don't believe that it
