usage: pyallel [-h] [-t] [-n] [-V] [--colour {yes,no,auto}] [commands ...]

Run and handle the output of multiple executables in pyallel (as in parallel)

positional arguments:
  commands              list of quoted commands to run in parallel e.g "mypy ." "black ."

                        each command is executed inside a shell, so shell syntax is supported as
                        if you were running the command directly in a shell, some examples are below

                             "MYPY_FORCE_COLOR=1 mypy ."          <- provide environment variables
                             "mypy | tee -a mypy.log"             <- use pipes to redirect output
                             "cat > test.log < other.log"         <- use input and output redirection
                             "mypy .; pytest ."                   <- run commands one at a time in sequence
                             "echo \$SHELL" or "\$(echo mypy .)"  <- expand variables and commands to evaluate (must be escaped)
                             "pytest . && mypy . || echo failed!" <- use AND (&&) and OR (||) to run commands conditionally

                        commands can be grouped using the group separator symbol (:::)

                             "echo boil kettle" "sleep 1" ::: "echo make coffee"

                        the above will print "boil kettle" and sleep for 1 second first before printing "make coffee"

                        command groups are ran in the sequence you provide them, and if a command group fails
                        (if a command fails inside the command group) the rest of the command groups in the sequence are not run

options:
  -h, --help            show this help message and exit
  -t, --no-timer        don't time how long each command is taking
  -n, --non-interactive
                        run in non-interactive mode
  -V, --version         print version and exit
  --colour {yes,no,auto}
                        colour terminal output, defaults to "auto"
