Subject: Capturing the results of shell execution
Date: Tue, 17 Jan 2017 15:05:29 +0000 [thread overview]
Message-ID: <87vatdu3pi.fsf@linaro.org> (raw)
I'm using org-babel snippets to automate some of my workflow. However
I'm not interested in dumping all of the compile output, I'd rather get
a simple value at the end to see if all was OK:
#+name: build-test
#+begin_src sh :results value
set -e
./configure --cross-prefix=aarch64-linux-gnu- --arch=arm64
make clean
make -j9
#+end_src
However there isn't a way to tell the difference between a failing
sequence and a passing one apart from *Org-Babel Error Output* being
popped up. It seems org-babel-eval just slurps up the return code and
blindly returns (buffer-string) regardless of the desires of the
:results keyword.
Is this an intentional limitation of babels sh evaluation?
Redirecting all the compile output in the snippet seems a little clumsy
a solution:
#+name: build-test
#+begin_src sh :results output
set -e
./configure --cross-prefix=aarch64-linux-gnu- --arch=arm64
make clean > /dev/null
make -j9 > /dev/null
echo "Build complete: `date`"
#+end_src
Ideally I'd like #+RESULTS to have a nice 0/1 which can be used to gate
other parts of the process.
Am I missing something?
