spawn a python executable and suspend until complete

Anonymous — Tue, 09 Jul 2019 13:54:23 GMT

Hi.

I would like to be able to spawn a python script from lisp and suspend lisp until the python script completes.

A good candidate seemed to be acet-sys-spawn,

but the following attempts did nothing and returned an exit code of -1.

(acet-sys-spawn 1 "c:\\tom\\tmp\\tmp5\\primitivelinesAndIndices.py")

(acet-sys-spawn 1 "C:\\Python27\\python.exe c:\\tom\\tmp\\tmp5\\primitivelinesAndIndices.py")

The invocation (acet-sys-spawn 1 "C:\\Program Files\\windows nt\\accessories\\wordpad.exe")

did start wordpad, waited until it was closed, then returned an error code of 0 as expected.

Also,

(command "shell" "C:\\Python27\\ArcGIS10.5\\python.exe c:\\tom\\tmp\\tmp5\\primitivelinesAndIndices.py")

will run the python script, but execution doesn't suspend, so lisp would have to poll for a state change somehow before retrieving the python scripts output, and that is a lot clunkier than what I want.

Any ideas or suggestions?

@Anonymous ,

Have you tried..?

(acet-sys-spawn 1 "C:\\Python27\\python.exe" "c:\\tom\\tmp\\tmp5\\primitivelinesAndIndices.py")

notice my 2 parentheses, this ensures that the .exe is the command and the .py is the argument.

Best,

Thanks!

That for suggesting setting both the executable and its file argument in their own sets of quotation marks. works exactly as I hoped.

That does function, but, while the console suspends, autocad keeps running. I will certainly keep this in mind when that behavior is wanted, which is equally likely. Thanks!
