Showcase

Code that helps organize the labs' projects and present them nicely

Purpose

The showcase is the first box of C4DT's Factory. Its purpose is to help labs at the IC faculty to present their most interesting projects to potential industrial customers.

Structure

The information regarding the IC labs and their projects is organized in YAML files as follows:

data
├── labs.yaml
├── LAB1
│   └── projects.yaml
├── LAB2
│   └── projects.yaml
├── ...
...

• labs.yaml contains the information on all the labs, each one indexed by an ID.
• Each projects.yaml, located in a subdirectory named after a lab ID, contains the information on that lab's projects.

The information is presented to the user via a small bottle application.

Yaml structure

A summary of the different entries found in the yaml structure. All text to be changed is written in (brackets).

Run the application locally

Ensure you have the required tools to create Python virtual environments. You can either install the dependencies in a virtual environment, or use devbox.

Install dependencies in a virtual environment

You might need to install a specific package depending on your distribution, e.g. on Debian python3-venv:

$ sudo apt install python3-venv

Use devbox

Install devbox from https://www.jetpack.io/devbox, then run:

devbox shell --pure

Create the virtual environment

Simply run make:

$ make

This will create a Python virtual environment, activate it, install the dependencies and run the showcase application.

The application listens by default on port 8080 in the path showcase; point your browser to http://localhost:8080/showcase.

Run the tests

$ make test

Run the application on a server

Assuming $APP_PATH is the directory containing the application, the following must be setup on the server (see also the mod_wsgi docs:

Clone the repository:

$ cd $APP_PATH && git clone [email protected]:c4dt/showcase.git

Create the Python virtual environment and install the dependencies:

$ cd showcase
$ make env

Configure an Apache virtual host for the app, containing in particular:

	WSGIDaemonProcess showcase user=showcase group=showcase processes=1 threads=5 python-home=$APP_PATH/showcase/venv
	WSGIScriptAlias / $APP_PATH/showcase/app.wsgi

	<Directory $APP_PATH/showcase>
		WSGIProcessGroup showcase
		WSGIApplicationGroup %{GLOBAL}
		Require all granted
	</Directory>

Restart Apache:

$ sudo /etc/init.d/apache2 restart

Tools

Linkchecker

When checking the links, you can use LinkChecker to scan all links from the showcase. The configuration file ./linkcheckerrc helps to clean up the result page of a linkchecker run. You can get the links to the project of a lab with the data.py file:

make env
. ./venv/bin/activate
./data.py

This will print out a list of all available labs. Launch the showcase:

make showcase &

Now you can launch linkchecker on all pages from a given lab:

For a list of available labs:

./check_lab_links.sh

Checking a given lab:

./check_lab_links.sh LAB_NAME

This will also check the links of the external websites.
