[Openmcl-devel] Create a CCL image that can quickly load Cocoa using a command-line workflow

Thanks for the hint to launch the executable within the built App.

This approach is almost working.

Here's what I would like to be able to do:
./[path-to-executable] -l tests.lisp -e '(quit)'

And have :cocoa already loaded in the image associated with that executable.

Here is what I have:
Clozure\ CL64.app/Contents/MacOS/dx86cl64 -e '(gui::start-cocoa-ide)' -l
test.lisp -e '(quit)'

This works except that I do not get any feedback (i.e., the program
freezes) if I cause lisp to throw an exception. Interesting thing is, if I
just build a default :cocoa app (with require :cocoa-application), I still
do not get any feedback if I cause lisp to throw an exception when typing
in the GUI REPL. The whole program freezes when I do this. Is this
issue reproducible on a machine other than mine? If I can fix this, then I
have a working solution.

Here is how I got there:
Comment out all but the first argument in the save-application call in the
build-ide function:

$ git df cocoa-ide/start.lisp
diff --git a/cocoa-ide/start.lisp b/cocoa-ide/start.lisp
index 478d8d4..2e59715 100644
--- a/cocoa-ide/start.lisp
+++ b/cocoa-ide/start.lisp
@@ -147,9 +147,10 @@
     (ccl:copy-file (ccl::kernel-path) kernel-file :if-exists :supersede
                    :preserve-attributes t)
     (save-application image-file
-                     :application-class 'cocoa-ide
-                     #+windows-target #+windows-target
-                     :application-type :gui)))
+                     ;:application-class 'cocoa-ide
+                     ;#+windows-target #+windows-target
+                     ;:application-type :gui
+                      )))

This change ensures that the CCL Gui App Window doesn't automatically
launch when running the executable. This is necessary because I would like
to pass arguments (the -l in particular) when launching the executable. If
the arguments to save-application are uncommented, I am not able to pass
any arguments when launching the executable, which means that I cannot pass
the important -l argument that loads the test file.

This change also decouples the terminal from the CCL GUI App listener (like
it is with Slime), so that compiler warnings stdout, etc. go to the
Terminal, and not the GUI App. This is important when running the tests,
because I want all of that trace to persist after the CCL image closes. If
it is placed on the GUI App's listener window, it disappears after running
through the tests. If it's placed on the Terminal, I can redirect it to a
file easily, or simply just scroll through the output after the tests run.

I'll be interested to see if anyone can reproduce the last issue I found.
Simple test procedure:
[1] Launch CCL
[2] (require :cocoa-application)
[3] double click the new app
[4] type (lslslslslsls) in the listener
[5] does it hang?
