iLambda is designed to aid teachers in setting up projects on iSENSE (www.isenseproject.org)--a system for collecting, visualizing, and sharing data.

##Concepts Demonstrated

• We modeled our database after a database in one of our homework assignments. We used set! and append to modify it.
• When parsing data stored in the database, we used filter and recursive processes to traverse through lists.
• We created an abstraction barrier between our database code and code to actually render the web pages. We created procedures to fetch data from our database.

##External Technology and Libraries

• We used calls in iSENSE's API to verify login credentials in iLambda.
• We also used iSENSE's racket-api to create projects.
• We also used Racket's built-in libraries: Web server and Net to create the webpage, submit through forms, and make get/post requests to the APIs.

####Kaitlyn's favorite line of code This is my favorite line because string interpolation in Scheme is very messy, and I am so proud I was able to figure out how to actually do this. This line makes a GET request to the iSENSE API by passing a URL with credentials that we obtain from the form.

(define url (format "http://isenseproject.org/api/v1/users/myInfo?email=~s&password=~s" (string->symbol (login-email cred)) (string->symbol (login-password cred))))

####Ravy's favorite line of code This code is for our Media Object Page. It created a browse button on the webpage that allows the user to upload a file from their computer.

(input ([type "file"][class "filestyle"] [name "file"]))

#How to Download and Run Simply download this repo as a ZIP or clone it. You must change a path in main.rkt to get the style to work on your computer. The path you must change is at the very bottom of the file and looks like (build-path "/Users/kaitlyncarcia/Repos/iLambda/") "htdocs")). The latest release as of 5/1 is 4.0.
