mini-file-format

Minimalized ini format with concrete format rules. Meant to be easily read and easily parsed. Ends with .mini i.e. config.mini.

Sections and Keys

• Sections are denoted by square brackets ([Section]).
• Subsections are nested within sections using dot notation ([Section.Subsection]).
• All (sub-) sections must be explicitly defined before used elsewhere.
• All (sub-) sections may only be defined once.
• (Sub-) sections can be empty.
• Keys within (sub-) sections use key = value syntax.
• Key and (sub-) section names may only contain a-z, A-Z, 0-9, and _.
• Empty keys (i.e., keys without values) are not allowed.
• Spaces outside of strings are ignored.
• Empty lines may be ignored
• Comments are denoted by # and may only appear on separate lines.

Supported Data Types

The format supports the following data types:

Integer

• Defined as a sequence of digits (0-9).
• Example: value = 5

String

• Strings are enclosed in double quotes ("").
• Strings support escape sequences using backslashes (\).
• Supported escape sequences:
  • \" for a double quote (")
  • \n for a newline
  • \t for a tab
  • \\ for a backslash
• Strings can be empty.
• Example: string = "My string
• Example: string = "Line 1\nLine 2"
• Example: string = "Tab\tSeparated"
• Example: string = "My \"escaped\" String"
• Example: emptyString = ""

Array

• Arrays are enclosed in square brackets ([]) and contain comma-separated values.
• Arrays may only contain one datatype.
• Arrays may be of any positive dimension.
• Arrays can be empty
• Example: array = [5, 6, 10]
• Example: array2d = [[5, 8], [9, 7], [23, 47]]
• Example: emptyArray = []

Boolean

• Boolean values are represented as either true or false.
• Example: myBool = false

Floating-Point Numbers

• Floating-point numbers use . for decimal notation or e for scientific notation.
• Floats always end with f.
• Floats may also be whole numbers without a decimal point.
• Example: anotherValue = 1.065f
• Example: thisToo = 1e18f
• Example: scientificFloat = 1.534e3f
• Example: wholeFloat = 1f

Hexadecimal Numbers

• Hexadecimal numbers are prefixed with 0x.
• Example: hexValue = 0xFA8

Binary Numbers

• Binary numbers are prefixed with 0b.
• Example: binValue = 0b0010010

Underscore in Numbers

• Numbers can contain underscores (_) for readability.
• Example: anotherDec = 1_000_375
