Pyallel

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

https://github.com/Danthewaann/pyallel/assets/22531177/8685eb92-aac5-440a-9170-30fd1460c53f

Requires Python >=3.8

Tested on Linux and MacOS only

Quick start

pyallel can be installed using pip:

pip install pyallel

You can also build an executable with the following (executables will be written to ./dist):

Build for generic linux

docker build -t pyallel . && docker run --rm --volume "$(pwd):/src" pyallel

Build for alpine linux

docker build -t pyallel-alpine -f Dockerfile.alpine . && docker run --rm --volume "$(pwd):/src" pyallel-alpine

Build locally

python -m venv .venv && source .venv/bin/activate && pip install . -r requirements_build.txt && ./build.sh

Once installed, you can run pyallel to see usage information, like so:

usage: pyallel [-h] [-t] [-n] [-V] [-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 e.g "mypy ." "black ."

                        can provide environment variables to each command like so:

                             "MYPY_FORCE_COLOR=1 mypy ."

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, --verbose         run in verbose mode
  -v, --version         print version and exit
  --colour {yes,no,auto}
                        colour terminal output, defaults to "auto"

Currently you can provide a variable number of commands to run to pyallel, like so:

[!IMPORTANT] If you need to provide arguments to a command, you must surround the command and it's arguments in quotes!

pyallel "MYPY_FORCE_COLOR=1 mypy ." \
        "black --check --diff ." \
        "pytest ."

TODOs

• Add custom parsing of command output to support filtering for errors (like vim's errorformat)
• Allow list of files to be provided to supply as input arguments to each command
• Allow input to be piped into pyallel via stdin to supply as standard input to each command
