Hi all,

I use SciTE for Ruby scripting. I wonder if it is possible to  
dynamically interact with my script via command prompt from within  
SciTE. For example I want to get user input and then print it to the  
command prompt window.

//script  
input=STDIN.gets  
puts input

It works if I execute the script from a prompt window but doesn’t work  
via SciTE. I wonder what is the Ruby way to interact with the user from  
the command prompt window.

Thanks,

Li

It does work for me.

I did use the output-pane for entering the data.
