BRIDGES(Python): Getting Started(Setup)

• If you do not have Eclipse installed, download it from the Pycharm site and install it on your computer.

• If you do not have Pip, install it from here

• Download the Bridges zip file from here
• In your terminal navigate to the Bridges directory (where you saved it).
• Run the command python setup.py install

• Visit the Bridges main page and create yourself an account by clicking the login button on the top navigation bar. Please ensure that your user id is devoid of spaces, as it will be used as part of the web link for your projects. After creating your account, click on your profile name in the upper right corner to view your profile. Once in your profile, you will see your API Key; you will need this API key in part 2 of the tutorial(as well as in every BRIDGES program you write). NOTE: Make sure to remember your password. There is no password recovery option, and you can only have one account per email address.

Step 3: Creating Project Click Create New project
Step 3b: Creating Project Name your project HelloWorld create a new enviornment using virtualenv
Step 3c: Creating Project. Choose a location for the virtual environment Choose the base interpreter for project - Python 3.* *Note, your location and base interpreter path will be different* Uncheck Inherit global variables and Check Make available for all projects. *Note, If you installed Bridges through the Zip file, Check Inherit global variables. Click create at the bottom right corner.
Step 4a: Installing Bridges (Skip to step 4c if using Zip file) Go to Project Settings -> Project Interpreter -> +/install
Step 4b: Installing Bridges Type in at the top Bridges Select Bridges on the left side Click Install Package
Step 4c: Verification To verify that you have successfully installed Bridges, look under the External Libraries section of your project and expand the python interpreter. If you have a Project in PyCharm named 'HelloWorld', and the expanded python interpreter/site-packages has the Bridges folder, you have completed the setup and are ready to build the Hello World class!

BRIDGES:Getting Started(Your First Bridges Program)

Step 1a: Create a new File Create a new class within your project File-->New-->Python File
Step 1b: Create a new File Name the file HelloWorld
Step 2: Now build the Bridges Program to illustrate a singly linked list First import the relevant Bridges classes	from bridges.bridges import * from bridges.sl_element import *
Create the bridges object with your API Key and User ID.	bridges = Bridges(0, "YOUR_USER_ID", "YOUR_API_KEY")
Create two singly-linked elements. Singly-linked elements can be linked together to create a linked-list structure.	sle0 = SLelement("Hello", "") sle1 = SLelement("World", "")
Link the elements	sle0.set_next(sle1)
Set visual attributes of the elements	sle0.get_visualizer().set_color("black") sle0.get_visualizer().set_opacity(0.5) sle1.get_visualizer().set_color("green")
Pass the handle of your data structure (reference to the first element) of your data structure	bridges.set_data_structure(sle0)
Visualize the data structure	bridges.visualize()
To summarize, your HelloWorld.py should look like this:	from bridges.bridges import * from bridges.sl_element import * class HelloWorld:          #create the Bridges object          bridges = Bridges(0, "YOUR_USER_ID", "YOUR_API_KEY")          #create two singly-linked elements          sle0 = SLelement("Hello", "")          sle1 = SLelement("World", "")          # create a singly-linked list          # by adding sle1 as sle0's next element          sle0.set_next(sle1)          #edit some visual properties of the two elements          sle0.get_visualizer().set_color("black")          sle0.get_visualizer().set_opacity(0.5)          sle1.get_visualizer().set_color("green")         #pass the first element of the list         bridges.set_data_structure(sle0)          # visualize the list          bridges.visualize()
Step 3: Running your Bridges program Once your code is in, run your project Run-->Run Run --> HelloWorld
Step 4: Visualize your data structure If your code compiles correctly, the Eclipse console will give you a link to the Bridges website. to view the visualization. Copy/paste this link into your favorite browser to view a visualization of the data structure you just created.
