Clozure Common Lisp中的运行程序不显示GUI窗口

Question

I am using ccl under win7 OS, I call run-program function in ccl console like this:

(ccl:run-program "notepad.exe" () :wait t)

After that, I can find the "notepad" process in the process list from "task manager", and ccl blocks to wait for "notepad" process to exit. But the GUI window of notepad do not show. It seems that the notepad is just running under background.

I am not sure whether I miss any parameter to "run-program", does anyone meet the same problem?
Any solution for this?

Answer 1

这对我在Windows 7上起作用，以使记事本窗口可见

(ccl:run-program "cmd.exe" '("/c" "notepad.exe") :wait nil)

Answer 2

I have the same problem under Windows Vista. My temporary workaround is to start a batch file, which contains the program to be started.

Eg C:/tmp/notepad-starter.bat contains:

notepad.exe %1

..which allows me to type

(ccl:run-program "C:/tmp/notepad-starter.bat" '("C:/tmp/notepad.pl") )

...which works fine and starts the notepad.exe process including the GUI. You even could dynamically create the batch file from out of Lisp first before starting it.

Answer 3

I found an even easyer way: create a batch file called eg. generic-batch-starter.bat which contains just %1 %2 %3 %4

You then can call executables as part of the parameter list:

(ccl:run-program "C:/tmp/generic-batch-starter.bat" '("notepad.exe" "textfile.txt"))
