This compiles simple common workflow language workflows to a shell script.

Example:

$ cwl2script test/revsort.cwl test/revsort-job.json
#!/bin/sh

# Workflow generated from file:///home/peter/work/cwl2script/test/revsort.cwl using cwl2script
set -x

# Run step file:///home/peter/work/cwl2script/test/revsort.cwl#rev
# depends on step file:///home/peter/work/cwl2script/test/revsort.cwl
mkdir -p /tmp/tmpwDQXXq  # output directory
mkdir -p /tmp/tmpWwRuUa  # temporary directory
rev /home/peter/work/cwl2script/test/whale.txt > /tmp/tmpwDQXXq/output.txt
rm -r /tmp/tmpWwRuUa     # clean up temporary directory

# Run step file:///home/peter/work/cwl2script/test/revsort.cwl#sorted
# depends on step file:///home/peter/work/cwl2script/test/revsort.cwl#rev
# depends on step file:///home/peter/work/cwl2script/test/revsort.cwl
mkdir -p /tmp/tmp2i5tmU  # output directory
mkdir -p /tmp/tmpEGP9Nz  # temporary directory
sort --reverse /tmp/tmpwDQXXq/output.txt > /tmp/tmp2i5tmU/output.txt
rm -r /tmp/tmpEGP9Nz     # clean up temporary directory

# Move output files to the current directory
mv /tmp/tmp2i5tmU/output.txt .

# Clean up staging output directories
rm -r /tmp/tmpwDQXXq /tmp/tmp2i5tmU

# Generate final output object
echo '{
    "output": {
        "path": "output.txt",
        "class": "File"
    }
}'
