⛏️sproc: subprocesseses for subhumanses ⛏

Run a command in a subprocess and yield lines of text from stdout and stderr independently.

Useful for handling long-running proceesses that write to both stdout and stderr.

Simple Example

import sproc

CMD = 'my-unix-command "My Cool File.txt" No-file.txt'

for ok, line in sproc.Sub(CMD) as sp:
    if ok:
         print(' ', line)
    else:
         print('!', line)

if sp.returncode:
    print('Error code', sp.returncode)

# Return two lists of text lines and a returncode
out_lines, err_lines, returncode = sproc.run(CMD)

# Call callback functions with lines of text read from stdout and stderr
returncode = sproc.call(CMD, save_results, print_errors)

# Log stdout and stderr, with prefixes
returncode = sproc.log(CMD)
