GMU CS Course-Semester Scraper

Purpose

The intended purpose of this tool is to find out in which semesters were specific CS classes offered.

You can use this to get an idea of when courses will be offered, to help you plan your schedule.

This program outputs in JSON format.

Requirements

  1. Java 11
  2. Apache Maven
  3. An internet connection

Compiling

Run mvn clean package from the project's root directory.

The output JAR file is ./target/CS-Archive-Catalog.jar from the project's root directory.

Execution

  1. Compile the project (see above).

  2. Run the created jar file (see above for path) using java -jar. Provide one argument which determines the key type of the output json: semester or course.

    • If you provide semester, then courses will be grouped by the semesters it was offered.
    • If you provide course, then the semesters will be grouped by the course number.

You can save the output of this program by using redirection in your shell.
