Here's a screen shot :)

Hi, 

Can anyone help me to fix this thing,
I like the screenshot above and try to tackle out,
the way Geany highlighting the current line (the line with cursor) like that.
Because my current line is much annoying, it highlight the background color 
to white and when I type in, the letters are white either. So I couldn't see 
what I
am typing in.

Please help!!!

Thanks

This setting lives in your filetypes.common file - this is shipped as part of 
the geany-dark-
scheme, where the setting can be found on line 24.

Mine - which looks approximately like the one in the screenshot above, is set 
like this:

current_line=0x0;0x2F2F2F;true;false

You can find your filetypes.common file wherever you installed the theme - see 
http://code.google.com/p/geany-dark-scheme/wiki/InstallGuide

But can I override the "current_line" attribute of filetypes.common just for 
some languages? The highlighted line it's nice on dark backgrounds, but on 
other languages not supported by geany-dark it's horrible.

I've been trying this with no success.

That just means other languages are not configured. You could add config files 
for those as well. It's not hard to do.

Thanks for the information. I also had this problem. Though, of course 
highlighting came up regarding syntax. Though, I was searching for highlighting 
that did not regard the syntax for the language. Though, I googled for geany in 
document highlighting or geany in program highlighting in order to fix the 
appearance of the white on white highlighting while typing an HTML document 
using the Vibrant Dark or Tango Dark syntax highlighting theme.
