python - IPython scripting - Exit script with status code -

i trying use ipython script git pre-commit hooks since has nice syntax run shell commands , converting stdout result list of strings (which makes easy processing).

i need return status code != 0 ipython script git pre-commit hook abort commit.

consider example script

#! /bin/ipython import sys sys.exit(1) 

running shell

$ ipython test.ipy 

but checking status code $ echo $? returns 0

is there way make ipython return non-zero status code?

open ipython , try running code interactively.

in [1]: import sys in [2]: sys.exit(1)  exception has occurred, use %tb see full traceback.  systemexit: 1  exit: use 'exit', 'quit', or ctrl-d. 

so, ipython catching systemexit exception. suggest using different interpreter particular job, nice ipython is. alternatively can use:

import os os._exit(1) 

however, skips sorts of important cleanup code (e.g. finally blocks) , bad idea.

edit:

this seems work. after writing can hear alarm bells in distance , there red flags waving. not sure that's about. anyway, create new script /usr/bin/ipysh with:

#!/usr/bin/python  import sys ipython.core import interactiveshell shell = interactiveshell.interactiveshell() shell.safe_execfile(sys.argv[1], {}, raise_exceptions=true,                     exit_ignore=false) 

make executable, set hook's hashbang #!/usr/bin/ipysh.
