plz-cmd 1.0.5

command line app for running configurable shell commands

plz-cmd

A shell command to execute standard/repeatable commands in a git repo

Installation

Install plz at the system level so that it only has to be installed once.

pip install plz-cmd

# sudo may be required on your machine
sudo pip install plz-cmd

It can also be installed inside a virtualenv. However, this means you'll have to install plz-cmd for each each virtualenv in use.

virtualenv venv
. venv/bin/activate

pip install plz-cmd

Example

plz looks for a plz.yaml file either in the current directory or in the root of the git repo you're currently in. This file can (and should) be checked into version control.

For a plz.yaml file located in the git root directory, commands run will be executed relative to that directory, not the current directory.

Suppose we have the following plz.yaml file:

commands:
  run:
    cmd: ./manage.py runserver
  test:
    cmd:
    - ./manage.py test
    - yarn test
  setup:
    cmd:
    - poetry install
    - poetry run ./manage.py migrate
    - yarn install
  ls:
    cmd: ls

The following commands would be available:

plz run
plz test
plz setup

Getting help

List all the available commands with:

plz
# or
plz help

Print the yaml schema for any defined command with plz help <command>:

> plz help test
[INFO] Using config: plz.yaml

test:
  cmd:
  - poetry run python -m pytest

Environment variables

Environment variables can be set for an individual command or globally for all commands.

# env variable for an individual command
commands:
  run:
    cmd: ./manage.py runserver
  test:
    cmd: ./manage.py test
    env:
      DJANGO_SETTINGS_MODULE: myapp.settings.test

global_env:
  ACCESS_TOKEN: 12345
commands:
  run:
    cmd: ./manage.py runserver

Globbing

plz supports asterisk expansion. For example, the cmd ls *.py will work as expected.

Runtime arguments

plz supports passing custom arguments when running the plz command. For example:

# bind to port 8001 instead of the default 8000
plz run 127.0.0.1:8001

Any passed arguments will be tested to see if they are file paths relative to the current directory when running the command. Using this repo as an example:

bash$ ls .*.yaml
plz.yaml               .pre-commit-config.yaml

bash$ cd plz

bash$ plz ls ../.*.yaml
