In my rails controller, I am doing the following : @output = `g++ j.cpp -o "prog" && ./prog`
This gives the output in the @output variable which i can display in my view. But the above works only if the j.cpp is correct and doesn't expect any user input. How can I use the stdin/stderr and stdout streams here so that : If the user has to give input, I open a dialog box on the view with a textfield where he/she can enter the input, and the program continues to execute. If there are any errors in the file, then I should be able to get the errors and display them to the user. I tried doing this : @output = `g++ j.cpp -o "prog" && ./prog| tee prog` This allows me to enter the user input at the server command prompt (the server log...i don't know what do we call it), but I want it to be entered in a textfield in the view.
