Aw: Re: Multiple colors in vte

["Gilzad Hamuni" <gilli4 gmx net>]

Hi Stephen and Marcus,

thanks for your answers.

My client application receives some control bytes from the server in a way that the attribute is specified at 
first and the the actual text comes right after that. Specifically it's the Wang/FICE protocol.
02 03 02 04 0E "foo" 02 03 02 05 0e " bar"
..would write a red "foo" and a cyan "bar" on the screen. So the escape sequences are standardized in their 
very own way I guess. To change the color of "bar" it would simply be overwritten with a new color code. 
Basic things like moving the cursor (01, 08, 09, 0a, 0c) or ringing the bell (07) work like in normal ascii 
standards.

I'm processing each byte in a state machine anyway, so setting the attributes one-by-one might not be the 
problem if doing so doesn't lead to lower performance or excessive memory usage. I'd be glad to know an 
example on how to achieve this.

Thanks once again.
