PWBM Local Development Tools

Requirements

Tool implemented for Python version 3.8

Installation instruction:

Virtual environment manager

pipenv documentation:

• pipenv

First the manager itself should be installed:

python3.8 -m pip install pipenv

Creating virtual environment

In terms of pipenv, virtual environment is just a folder. That means, that all you have to do is to create a folder and run following command:

pipenv install --python 3.8

A virtual environment will for Python version 3.8 will be created.

Virtual environment usage

There are two ways to work with virtual environment:

1. It can be activated by following command:

pipenv shell

After activating the environment command may be run as pwbm <command>

2. Running command without activating environment:

pipenv run pwmb-sp <command>

Note: Both this option assume that current folder is the folder with virtual environment

Install Python package:

After creating virtual environment, execute following command:

pipenv install --python 3.8 pwbm-sp-dev

This will install the latest package version

Verify installation

pipenv run pwbm-sp

If everything was installed correctly, help message will be printed

Installing legacy versions

Toolset supports installation of legacy versions.

Installation of particular version:

pipenv install --python 3.8 pwbm-sp-dev==0.0.0

Where 0.0.0 is replaced with package version

NOTE: It's NOT possible to have multiple version of the package within same virtual environment. If you want to use multiple versions - install them in separate environments.

Features

This command will run file from specified location. If custom scraper needs parameters, they can be provided in a following way:

pwbm-sp run /path/to/input/file.py -p param1=value1 param2=value2

Omitting --output parameter will result printing pipeline configuration into console.

If custom scraper needs parameters, they can be provided in a following way:

pwbm-sp wrap --input /path/to/input/file.py -p param1=value1 param2=value2
