About

trivial-debug-console is a tiny little library to make writing GUI applications in Common Lisp easier on Windows. The free lisp implementations like SBCL and CLISP produce "text-mode" executable images on windows, which means they pop up a console window when run. You could create a launcher to hide the window, but then you couldn't do any debugging in the image.

trivial-debug-console lets you wrap a function such that the console window will be un-hidden whenever the debugger is entered, and re-hidden after the condition has been handled. You get the console window for just as long as you need it, then it gets out of your way.

Usage

There are two ways to use trivial-debug-console:
  1. (debuggify func &rest args) will apply func to args with the debug wrapper.
  2. (with-debug-console &body body) will wrap body in a lambda and pass it to debuggify, to make wrapping a series of actions easier.

Notes

  • This only works on windows (I'm still thinking about how to make it work on X-windows systems).
  • trivial-debug-console goes to lengths to not disrupt normal error-handling mechanisms. *DEBUGGER-HOOK* and the regular error-handling mechanisms should all work normally.
