hellpipe

wip: generate python scripts from (s)hell pipelines

Intended to be used with a shell plugin to make those oneliners that get out of hand more manageable.

Example

curl "https://httpbin.org/get?test=123" | jq ".headers|keys[]" -r | xargs -L 1 echo

import requests
import subprocess
import sys
import shlex

# generated with hellpipe

def main():

    params = {"test": ["123"]}
    res = requests.get("https://httpbin.org/get", params=params).text

    proc = subprocess.Popen(
        ["jq", ".headers|keys[]", "-r"],
        stdin=subprocess.PIPE,
        stdout=subprocess.PIPE,
        stderr=sys.stderr,
    )
    (stdout, _) = proc.communicate(res.encode("utf-8"))
    out_jq = stdout.decode("utf-8")

    for i in shlex.split(out_jq, posix=True):
        print(i)  # TODO


if __name__ == "__main__":
    main()
