Quit command

[Toby Gifford]

Does extempore have a command that will cause it to quit? Other than deliberately seg-faulting.

You're probably after:

(quit 0)

But this is still pretty brute force. There's no elegant quit.

How does the aot build system manage it? What I'm trying to do is call extempore like a command line function and parse it's output in a perl script. I'm doing this already with "extempore --print-devices", but want to do something similar with "extempore --eval \"(sys:load \"libs/external/portmidi.xtm\") (pm_print_devices)\"

or equivalent with --run option. Is there a recommended way to control what extempore outputs? I guess I can redirect STDOUT from within an extempore script, though that's probably not portable

You're obviously going to have some trouble with this as we use stdout as the Extempore log :(

But that aside you just want this right?

<start file blah.xtm>

(println "Toby's output goes here!")

(quit 0)

<close file blah.xtm>

$ ./extempore --run blah.xtm

OR alternatively

$ ./extempore --eval "(begin (println \""Toby output\"") (quit 0))"

where the \""quoting\"" will depend on the platform and the shell (this example from windows powershell)

would you not be better off writing to a file and then parsing the file with perl?

[Andrew Sorensen]

another alternative might be to use system, popen etc..
