Introduction

USF-Python is a Python library that provides access to the USF format for efficiency and universality.

Features

• Lightweight & Compact: Optimized for efficient storage and fast parsing.
• Supports Course Schedules: Store course names, instructors, locations, time slots, and week rules.
• Flexible Week Rules: Supports "all", "even", and "odd" week patterns.
• Simple API: Easy to read, write, and manipulate USF files.
• Cross-Platform: Works on all platforms supporting Python.

Installation

You can simply install the package with pip

pip install usf

or install it locally

python setup.py install

Usage

import usf

# Reading a USF file
data = usf.read("schedule.usf")
if usf.is_valid(data):
    print("Valid USF file")
    subjects = usf.get_subjects(data)
    print(subjects)
else:
    print("Invalid USF file")

# Creating a USF file
# Initialize the USF Generator (version 1 by default)
usf_generator = usf.USFGenerator()

# Add subjects
usf_generator.add_subject("Mathematics", simplified_name="Math", teacher="Dr. Smith", room="Room 101")
usf_generator.add_subject("Physics", simplified_name="Phys", teacher="Prof. Johnson", room="Room 203")

# Add class periods
usf_generator.add_period("08:00:00", "09:30:00")
usf_generator.add_period("10:00:00", "11:30:00")

# Add schedule entries
usf_generator.add_schedule(day=1, week_type="all", subject="Mathematics", period_index=1)  # Monday
usf_generator.add_schedule(day=2, week_type="odd", subject="Physics", period_index=2)  # Tuesday (Odd Week)

# Generate the USF data and save it to a file
usf_generator.save_to_file("schedule.usf")

# Adding a Course to an Existing USF File
data = usf.read("schedule.usf")
usf.add_subject(data, {
    "name": "Physics",
    "teacher": "Prof. Johnson",
    "location": "Room 203",
    "time": [3, 4],
    "week": "odd"
})
usf.save(data, "updated_schedule.usf")

# Generating a USF File from Scratch
schedule = usf.create()
usf.add_subject(schedule, {
    "name": "Computer Science",
    "teacher": "Ms. Lee",
    "location": "Lab 2",
    "time": [5, 6],
    "week": "even"
})
usf.save(schedule, "new_schedule.usf")

USF Format Specification

USF data is structured as a compact array:

• name: Course name (string)
• teacher: Instructor name (string)
• location: Classroom or venue (string)
• time: List of tuples representing periods, e.g., [(1, 2)] means periods 1 and 2
• week: "all", "even", or "odd"

Example JSON representation:

{
  "version": 1,
  "subjects": {
    "Mathematics": {
      "simplified_name": "Math",
      "teacher": "Dr. Smith",
      "room": "Room 101"
    },
    "Physics": {
      "simplified_name": "Phys",
      "teacher": "Prof. Johnson",
      "room": "Room 203"
    }
  },
  "periods": [
    ["08:00:00", "09:30:00"],
    ["10:00:00", "11:30:00"]
  ],
  "timetable": [
    [1, "all", "Mathematics", 1],
    [2, "odd", "Physics", 2]
  ]
}
