#We need to check that all samples have been compiled without error.
#For find program, the -exec argument is a filter predicate just like -name. It only affects whether the file is "found", not the find's exit code.
#One way to solve this problem is to check whether we have any python pipelines that cannot compile. Here the exit code is the number of such files:
#RUN  bash -e -c 'exit $(find . -maxdepth 2 -name "*.py" ! -exec dsl-compile --py {} --output {}.tar.gz \; -print | wc -l)'
#I think it's better to just use a shell loop though.
#RUN  for pipeline in $(find . -maxdepth 2 -name '*.py' -type f); do dsl-compile --py "$pipeline" --output "$pipeline.tar.gz"; done
#The "for" loop breaks on all whitespace, so we either need to override IFS or use the "read" command instead.
