Enjoy your time using OMEGAlpes !

Installation as a developer and local branch creation

  1. Create a new folder in the suitable path, name it as you wish for example : OMEGAlpes

  2. Clone the OMEGAlpes library repository

    Command lover:

        git clone

    Pycharm lover:

    Open Pycharm
    On the Pycharm window, click on "Check out from version control" then choose "Git".
    A "clone repository" window open.
    Copy the following link into the URL corresponding area:

    Copy the path of the new folder created just before.
    Test if the connection to the git works and if it works click on "Clone".
    Once OMEGAlpes is cloned, you must be able to see the full OMEGAlpes library on Pycharm or on another development environment.

    If the connection does not work and if you are working with local protected network, please try again with the wifi.

  3. First, choose or change your project interpreter

    Pycharm lover:

    Click on the yellow warning link or go to "File", "settings...", "Project Interpreter"

    You can:

    • either select the "Python 3.6" project interpreter but you may change the version of some library that you could use for another application
    • either create a virtual environment in order to avoid this problem (recommended).
      Click on the star wheel near the project interpreter box. Click on "add...".
      Select "New environment" if it not selected.
      The location is pre-filled, if not fill it with the path of the folder as folder_path/venv
      Select "Python 3.6" as your base interpreter
      Then click on "Ok"

  4. You can install the library on developing mode using the following command in command prompt once your are located it on the former folder. If you are calling OMEGAlpes library in another project, the following command enables you to refer to the OMEGAlpes library you are developing

     python develop
  5. If it is not already done, install the library requirements.

    Command lover:

         pip install <library_name>

    If required, the command to upgrade the library is :

         pip install --upgrade <library_name>

    Pycharm lover:

    You should still have a yellow warning.
    You can:

    • install automatically the libraries clicking on the yellow bar
    • install automatically the library using pip with Pycharm on "File", "settings...", "Project Interpreter", "+", and choosing the required library as indicated in the Library Installation Requirements part
  6. Finally, you can create your own local development branch.

    Command lover:

     git branch <branch_name>

    Pycharm lover:

    By default you are on a local branch named master.
    Click on "Git: master" located on the bottom write of Pycharm
    Select "+ New Branch"
    Name the branch as you convenience for instance "dev_your_name"

  7. Do not forget to "rebase" regularly to update your version of the library.

    Command lover:

     git rebase origin

    Pycharm lover:

    To do so, click on "VCS", "Git", "Fetch" Then, click on your branch name on the bottom write of the Pycharm window select "Origin/master" and click on "Rebase current onto selected"

  8. For contribution, have a look to Once your code is ready for contribution, do a last rebase (see 7.) and then, request for a merge with the master branch in OMEGAlpes gitlab

If you want to have access to other examples and study cases, please have a look to the user's installation.

Enjoy your time developing OMEGAlpes!
