MaRChE

MAssive Repository CHanges for Everyone

Installation

From source

Use virtualenv to separate MaRChE environment from system one.

$ git clone git@github.com:openforceit/marche.git
$ cd marche
$ virtualenv -p python3 venv
$ source venv/bin/activate
(venv)$ python3 -m pip install -r requirements.txt

From pypi

$ pip3 install marche

Usage

Get scripts list

$ cd YOUR_ADDONS_PATH
$ marche available-scripts

A list of scripts (folders in scripts path) will be showed.

Every folder is callable as a script.

(venv)$ python3 marche.py script
    -t TOKEN
    [--bar/--no-bar]
    [--collect-pr/--no-collect-pr]
    SCRIPT_NAME
    [--] [<script_options>]

SCRIPT_NAME is the script name that user can get from available-scripts

--bar/--no-bar Show or hide progress bar. Default value show the bar.

--collect-pr/--no-collect-pr Show or hide all the Pull Requests created by MaRChE. Default value show the collected pr.

script_options is a list of POSIX-style, whitespace-separated arguments that are passed to the script. These arguments may or may not be required depending on the script itself. Check the script documentation for more details.
