Checks if all input fields in the '#principia-table' are empty.

Exports the filtered data from the table to a JSON file.

Exports the filtered data from the table to a CSV file.

Represents a Graph containing nodes and their relationships.

const chapters = getChapterNumbers()
console.log(chapters) // [1, 2, 3, ...]

// Assuming the instance has a nodes property populated as:
// {
//     node1: { properties: { chapter: '1', number: '1.0' } },
//     node2: { properties: { chapter: '1', number: '1.1' } },
//     ... other nodes
// }
getChapterNodes(1);
// Output: Array of nodes for chapter 1, with placeholders for missing primary decimalPart values.

// Given nodes with properties {chapter: '1', number: '1.x'} etc.
plot(1, 0, 0);
// Output: Array of plotted nodes for chapter 1 and the maximum x-coordinate value.

Retrieves the length of the decimal part of a given number represented as a string.

This function splits the number by the decimal point and returns the length of the decimal part if it exists. If the number does not have a decimal part, it returns 0.

// Example with a decimal part
const length = getDecimalLength('123.456')
console.log(length) // Outputs: 3

// Example without a decimal part
const length = getDecimalLength('123')
console.log(length) // Outputs: 0

Retrieves the decimal part of a given number represented as a string.

This function splits the number by the decimal point and returns the decimal part if it exists. If the number does not have a decimal part, it returns null.

// Example with a decimal part
const decimal = getDecimalPart('123.456')
console.log(decimal) // Outputs: '456'

// Example without a decimal part
const decimal = getDecimalPart('123')
console.log(decimal) // Outputs: null

Downloads the provided chapter data as a JSON file.

• Error: Throws an error if the browser does not support Blob or URL.createObjectURL.

Converts a given number to its Roman numeral representation.

Roman numerals are created by combining symbols and adding values. This function handles numbers up to 3999 (inclusive). For numbers outside this range, an 'Appendix' string is returned. The Roman numeral system uses seven symbols: I, V, X, L, C, D, and M.

Retrieves the value of a specified query parameter from the URL.

This function parses the current page's URL and extracts the value of the given query parameter. If the parameter is not found, it returns null.

// Assuming the URL is: http://example.com/?foo=bar
const value = getQueryParam('foo')
console.log(value) // Outputs: 'bar'

// Assuming the URL is: http://example.com/?foo=bar
const value = getQueryParam('baz')
console.log(value) // Outputs: null

Finds the labels for a given chapter number from the provided data and labels.

This function attempts to locate the correct labels for a chapter by its number. If the chapter number ends with '.0', it increments the suffix until it finds a match or exceeds a limit. Once found, it retrieves the corresponding labels from the provided labels object.

const chapterNumber = '1.0'
const data = {
  volume1: [{ properties: { number: '1.1', volume: 1, part: 1, section: 1, chapter: 1 } }]
}
const labels = {
  default: {
    "Volume I": {
      "Part I": {
        title: "Part 1 Title",
        sections: {
          1: {
            title: "Section 1 Title",
            chapters: {
              1: { title: "Chapter 1 Title" }
            }
          }
        }
      }
    }
  }
}
const result = findLabel(chapterNumber, data, labels)
console.log(result) // Outputs: { "part-label": "Part 1 Title", "sect-label": "Section 1 Title", "chap-label": "Chapter 1 Title" }
