[Texmacs-dev] Document tree manipulation

[sgulati]

Hi everybody

I was thinking of making a texmacs plug-in and for that I would like  
to start off by making a scheme file with provision for changing the  
text colors according to a given parameter. I have made a parser and  
suppose I would like the text to appear green if a string was parsed  
correctly depending on my parser's output and red otherise. I could  
parse the string when the mouse pointer has been taken off the string.  
The colors should be changed by manipulating the document tree and I  
would like to know the files where I would find the appropriate  
functions for doing the same. Any further advice is welcome as well.  
Please help!

regards,
