Quick-start

Use the structures

Structs in Chrononuensis are lightweight data structures designed to hold parsed data. They are optimized for performance and memory efficiency. They are immutable where possible, ensuring data integrity.

Manually create a struct by passing values

You can create a struct directly by passing its required values to the constructor.

Chrononuensis follows a consistent parameter ordering for struct constructors and parsers. This order follows a decreasing specificity pattern, similar to how DateTime works in .NET. i.e. for the YearMonth struct, Year comes before Month, following a logical decreasing order.

// Create a Year-Month period for July 2025
var yearMonth = new YearMonth(2025, 7);

Parsing from a string

Instead of manually creating a struct, you can parse a formatted string to obtain a struct.

If you have a formatted string “2025-08” and want to convert it into a YearMonth struct, use the Parse method:

// Parse a period Year-Month for August 2025
var other = YearMonth.Parse("2025-08", "yyyy-MM");

In this example,

• 2025-08 is the input string.
• yyyy-MM is the format that defines how the input should be interpreted.

The parser extracts year and month from the string and returns a YearMonth struct.

Use the parsers

Parsers in Chrononuensis are flexible tools that extract structured information from input strings. Their role is not to instantiate predefined structs or classes, but rather to return extracted components (as integers) so that you can use them to create your own structures.

Instead of returning a predefined struct, a parser simply extracts and returns individual components. For example, given an input string like "2025-08":

var parser = new YearMonthParser();
(int year, int month) = parser.Parse("2025-08", "yyyy-MM");
