In a nutshell

pype-cli is a CLI-configurable command-line tool to orchestrate sets of other command-line tools. It simplifies the creation, orchestration and access of Python scripts that you require for your development work, process automation, etc.

Installation

The core package can be installed using python3 -m pip install pype-cli or pip3 install pype-cli. Refer to the usage section on configuration options.

Usage

pype-cli builds upon plugins and pypes. A pype is a single Python script whereas a plugin is basically a Python module that extens pype-cli with a collection of pypes.

pype-cli ships with one built-in plugin called pype.config that is used to configure pype-cli. All of the required information will be stored to a local JSON-configuration file that defaults to ~/.pype-config.json. To configure a custom configuration file use the environment variable PYPE_CONFIGURATION_FILE, e.g. in your ~/.bashrc file set export PYPE_CONFIGURATION_FILE=/path/to/myconfig.json.

Basic operations

  • List all available pypes: pype -l
  • Open pype-cli's configuration file: pype -o
  • Refer to pype ... -h for further information on the command-line

Install pype autocompletion and aliases

pype-cli's main benefit is that is is extendable with custom plugins and that it will allow you to immediatelly browse and use newly created and existing plugins/pypes by using the <TAB> key and by configuring short aliases. To enable the functionality it is required to install a source-script to your shell's rc-file that will be executed everytime you open a shell.

  • Run pype pype.config install-shell -t ~/.bashrc for bash shells
  • Run pype pype.config install-shell -t ~/.zshrc for zsh shells

Un-/register plugins

  • Register an existing plugin: pype pype.config plugin-register -n myplugin -p ~/pype_plugins (myplugin is a Python module with at least an __init__.py file and ~/pype_plugins a folder where the plugin is stored)
  • On-the-fly create and register a new plugin: pype pype.config plugin-register -c -n myplugin -p ~/pype_plugins
  • Unregister (but not delete) a plugin: pype pype.config plugin-unregister -n myplugin

Create, open and delete pypes

To create a new pype you need to decide to which plugin you want to add the pype, e.g., myplugin.

  • Create a new pype from a template: pype myplugin -c mypype
  • Create a new pype from a template with less boilerplate: pype myplugin --minimal -c mypype or pype myplugin -mc mypype
  • Create a new pype from minimal template and open immediately: pype myplugin --minimal --edit -c mypype or pype myplugin -mec mypype
  • Open a pype in your default editor: pype myplugin -o mypype
  • Delete a pype: pype myplugin -d mypype

Un-/register aliases

If you have selected a pype from a plugin you can set aliases for it. Afterwards you need to start a new shell session or source your rc-file to activate the aliases. New aliases are stored in the configuration file.

  • Register an alias: pype -r mm myplugin mypypealias mm="pype myplugin mypype"
  • Register an alias with options: pype -r mm myplugin mypype -o opt1 -valias mm="pype myplugin mypype -o opt1 -v"
  • Unregister an alias: pype -u mm

Shared code for plugins

If your plugin contains shared code over all pypes you can simply put it into a subpackage of your plugin or into a file prefixed with __, e.g., __commons__.py. pype-cli will only scan / consider top-level Python scripts without underscores as pypes.

Development

  • Run ./make shell to open a pipenv shell with the required shell configuration
  • Run pype to operate locale development version (it will react to code changes)
