Hello everyone.
i am using Slack 10.0. The xterm under KDE works fine,and have syntax hightlighting feature.
But the xterm under GNOME didn't have syntax hightlighting.(so pity!)
And i prefer GNOME than KDE.

I'd like to know how to let xterm under GNOME have syntax highlighting.

Thank you!

Are you sure there is no syntax highlighting?

I think it is just the colour of syntax highlight is same as background, therefore you can't see it.

You can meddle with xterm properties.

Open a terminal, and man xterm for the options

This is what I use in fluxbox,
-ls login new pty
-bg background colour
-bd bold colour
-fg foreground colour
-cr the blinking thing
-hc highlight colour
-ms mouse curser colour
-sl scroll line (200 lines to remember)
-pc can't remember.

you can also edit ~/.Xdefaults to set that stuff, so you don't have to type it in every time you start an xterm. here's mine, and you can google around for more examples:
