======= Material that will be used / shown in the workshop =======


In [[https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop|our workshop's gitlab repository]] we have placed some projects:
  - a plugin called ''wetdry'': it will be used as a showcase in the hands-on. It's a functional plugin straight away. It has a ''docs/'' folder with jupyternotebook files where each part of the plugin is commented almost line-by-line. It will be run by the users. The repository is [[https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop/wetdry|this one]].
  - a plugin called ''wetdry_debug'': a modified version of the previous one. Is incomplete, it has some bugs. It will be used to explore it by the users, test it and run it. The repository [[https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop/wetdry_debug|is this one]].
  - a plugin called ''wetdry_plus'': a more complex version of the ''wetdry'' plugin with added capabilities, like input from databrowser and incall to other freva plugins. It will not be shown. The repository is [[https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop/wetdry_plus|this one]].

In order to follow the hands-on you will need to download them and place them somewhere where the //evaluation system// (i.e. XCES) will be able to //see// them.


To look and execute the code we can do it [[login_shell|via the shell terminal]] or via [[connec2jupyterhub|DKRZ's jupyterhub]].

====== Steps for downloading the plugins ======

First thing we will go to (e.g.) our /home directory and create a folder that will contain these projects:
<code bash>
$ cd ~
$ mkdir plugin-workshop
$ cd plugin-workshop/
</code>

Now, we will download the repositories. To download a git repository there 3 ways:
  - download it. You can download it in different formats (zip, tar, etc.) but it will be downloaded to your local folder (your pc's folder) and then you will need to move it to your DKRZ's ''/home'' directory anyway.
  - clone it via **https**. Advantage: straightforward. Disadvantage: need to type ''<username>'' and ''<password>'' everytime.
  - clone it via **ssh**. Advantage: **no** need to type ''<username>'' and ''<password>'' everytime. Disadvantage: you previously need an ssh key for that. This will be shown in the workshop.

Currently, we will use the most straightforward way, i.e., via **https**, for that we only need to copy the address (e.g. [[https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop/wetdry.git|wetdry]]) and (in your newly created folder) follow the instructions entering your username and password:

<code bash>
$ pwd
/path/to/your/plugin/folder/
$ git clone https://gitlab.dkrz.de/freva/plugins4freva/plugin_workshop/wetdry.git
Cloning into 'wetdry'...

Username for 'https://gitlab.dkrz.de': <username>

Password for 'https://<username>@gitlab.dkrz.de':

</code>

Now we can go to our plugin and look its contents:

<code bash>
$ cd wetdry
$ tree
.
|-- README.md
|-- software
|   |-- getsoftware4wetdry
|   `-- getsoftware4wetdry-TEMPLATE
|-- src
|   |-- wetdry_plotter.py
|   |-- wetdry_script.sh
|   `-- wetdry_wrapper.py
`-- test
    `-- test.sh

3 directories, 7 files
</code>

\\ \\ 
**For the workshop we will need to do this 2 times, for ''wetdry'' and ''wetdry_debug''** so we finally have something like:

<code bash>
$ cd /path/to/your/plugin/folder/
$ ls
wetdry/ wetdry_debug/
</code>

\\ \\ 
We left the ''wetdry_plus'' so the users can navigate and compare it with ''wetdry''. We also encourage you to explore it and run it.
