# 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.
|
|
- Values may never reach over multiple lines.
|
|
- 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 are ignored as long as they don't split up names or values.
|
|
- Spaces are not allowed during (sub-) section declaration.
|
|
- Empty lines are ignored.
|
|
- Comments are denoted by `#` and may only appear on separate lines.
|
|
- Cases are sensitive (for both names and values), except where otherwise noted.
|
|
- The underlying size of any type is application specific.
|
|
- The parsing behavior of an illformed file is undefined.
|
|
|
|
## Supported Data Types
|
|
|
|
The format supports the following data types:
|
|
|
|
### Integer
|
|
- Defined as a sequence of digits (`0-9`).
|
|
- May be suffixed with `x` to be interpreted as hexadecimal (`0-9`, `a-f`, `A-F`).
|
|
- May be suffixed with `b` to be interpreted as binary (`0-1`).
|
|
- May contain underscores (`_`) for better readability.
|
|
- Example: `value = 5`
|
|
- Example: `hexValue = FA8x`
|
|
- Example: `binValue = 0010010b`
|
|
- Example: `anotherDec = 1_000_375`
|
|
|
|
### 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 may be empty.
|
|
- Example: `string = "My string"`
|
|
- Example: `string = "Line 1\nLine 2"`
|
|
- Example: `string = "Tab\tSeparated"`
|
|
- Example: `string = "My \"escaped\" String"`
|
|
- Example: `string = "My string with a \\ <- backslash"`
|
|
- Example: `emptyString = ""`
|
|
|
|
### Array
|
|
- Arrays are enclosed in square brackets (`[]`) and contain comma-separated values. A space may follow after a comma.
|
|
- Arrays may only contain one datatype at a time.
|
|
- Arrays may be of any positive dimension.
|
|
- Arrays may be of any positive length.
|
|
- Arrays may be empty.
|
|
- Example: `array = [5, 6, 10]`
|
|
- Example: `array2d = [[5, 8], [9, 7], [23, 47]]`
|
|
- Example: `array2d = [[9], [50, 3], [54, 12, 46, 37]]`
|
|
- 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`/`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`
|
|
- Example: `wholeFloat = 5.f`
|
|
|
|
## Example Structure
|
|
```text
|
|
[MySection]
|
|
myInteger = 5
|
|
myString = "My String"
|
|
myArray = [5, 6, 10]
|
|
myBool = false
|
|
|
|
# A comment
|
|
[MySection.MySubsection]
|
|
myFloat = 1.065f
|
|
myFloat2 = 1e18f
|
|
hexValue = FA8x
|
|
|
|
[MySection.MySubsection.AnotherSubsection]
|
|
binValue = 0010010b
|
|
|
|
# Another comment
|
|
anotherDec = 1_000_375
|
|
```
|
|
|
|
## What not to do
|
|
```text
|
|
[My-Section] | Invalid character in section name.
|
|
myFloat = 1.5 | Does not end with f.
|
|
myBool = True | Should not be capitalized.
|
|
myArray = [5, "Hi"] | Arrays can only contain one datatype at a time.
|
|
myArray2 = [[5, 6], 1] | Technically same as above, dimensions must match across all arrays.
|
|
myString = 'Hello' | Strings may only be encapsulated by ".
|
|
my-value = 5 | Invalid character in key.
|
|
|
|
[MyOtherSection.Subsection] | "MyOtherSection" has not been defined before.
|
|
myValue = 16 # a comment | Inline comments are not allowed.
|
|
|
|
[MyOtherSection]
|
|
myArray = [ | Values may not span over multiple lines.
|
|
[5, 7],
|
|
[9. 2]
|
|
]
|
|
```
