  • Parameters:

    • text: The text in which potential HTTP status codes are to be identified.

  • Description: This method employs a regular expression to identify sequences that match the structure of HTTP status codes. It captures three consecutive digits representing HTTP status codes.

  • Usage:

    String text = 'The HTTP status codes returned were 200, 404, and 500.';
List<String> extractedCodes = theClass.httpStatusCodes(text);

  • Example:

    String text = 'The HTTP status codes returned were 200, 404, and 500.';
List<String> extractedCodes = theClass.httpStatusCodes(text);
// Result: ['200', '404', '500']

  • Return Value:

    • A list containing potential HTTP status codes extracted from the input text.

  • Note:

    • The regular expression pattern used captures sequences comprising three consecutive digits representing HTTP status codes.

  • Considerations:

    • Validate the accuracy of the regular expression pattern based on the specific structure or format of HTTP status codes in the context.

coordinates

The coordinates method, part of the class or utility, is intended to extract potential geographical coordinates from the provided text.

  • Method Signature:

    static List<String> coordinates(String text)

  • Parameters:

    • text: The text in which potential coordinates are to be identified.

  • Description: This method utilizes a regular expression to identify sequences resembling geographical coordinates. It captures numeric values potentially representing latitude and longitude coordinates with various formats.

  • Usage:

    String text = 'The coordinates found were 40.7128° N, 74.0060° W and -33.8688° S, 151.2093° E.';
List<String> extractedCoords = theClass.coordinates(text);

  • Example:

    String text = 'The coordinates found were 40.7128° N, 74.0060° W and -33.8688° S, 151.2093° E.';
List<String> extractedCoords = theClass.coordinates(text);
// Result: ['40.7128° N', '74.0060° W', '-33.8688° S', '151.2093° E']

  • Return Value:

    • A list containing potential geographical coordinates extracted from the input text.

  • Note:

    • The regular expression pattern used captures sequences resembling latitude and longitude coordinates in various formats.

  • Considerations:

    • Ensure the regular expression accurately captures geographical coordinates based on the requirements and variations in their formats.

extractProgrammingKeywords

The extractProgrammingKeywords method, part of the class or utility, is designed to extract programming keywords from the provided text based on a specified programming language.

  • Method Signature:

    static List<String> extractProgrammingKeywords(String text, String language)

  • Parameters:

    • text: The text in which programming keywords are to be identified.
    • language: A string specifying the programming language ('Dart' or other) for keyword extraction.

  • Description: This method utilizes a regular expression to identify sequences that match the provided programming language's keywords. It captures words representing programming language keywords in a case-insensitive manner.

  • Usage:

    String text = 'The code snippet contains keywords like abstract, dynamic, and if.';
List<String> extractedKeywords = theClass.extractProgrammingKeywords(text, 'Dart');

  • Example:

    String text = 'The code snippet contains keywords like abstract, dynamic, and if.';
List<String> extractedKeywords = theClass.extractProgrammingKeywords(text, 'Dart');
// Result: ['abstract', 'dynamic', 'if']

  • Return Value:

    • A list containing identified programming keywords extracted from the input text based on the specified programming language.

  • Note:

    • The method distinguishes between programming languages via the language parameter and extracts corresponding keywords using a pre-defined list of keywords for each language.
    • The regular expression pattern used captures words representing programming language keywords in a case-insensitive manner.

  • Considerations:

    • Ensure proper specification of the programming language ('Dart' or other) to extract the relevant keywords.
    • Modify the keywordList variable to include the complete list of keywords specific to each supported programming language.
