KYAML Syntax Guide
KYAML uses JSON-compatible flow-style syntax while preserving YAML's comment functionality. This guide covers KYAML syntax rules and best practices in detail.
Basic Syntax
Objects (Maps)
Use curly braces `{}` to represent objects, with key-value pairs separated by commas
{
"key1": "value1",
"key2": "value2",
"nested": {
"subkey": "subvalue",
},
}Arrays (Sequences)
Use square brackets `[]` to represent arrays, with elements separated by commas
{
"fruits": ["apple", "banana", "orange",],
"numbers": [1, 2, 3,],
"mixed": [
"string",
42,
{"nested": "object"},
["nested", "array"],
],
}Data Types
Strings
All string values must use double quotes
{
"simple": "hello world",
"with_spaces": "hello world",
"with_quotes": "He said \"Hello\"",
"multiline": "Line 1\nLine 2\nLine 3",
"empty": "",
}Numbers
Numeric types don't need quotes, write directly
{
"integer": 42,
"float": 3.14,
"negative": -10,
"exponential": 1.23e4,
"zero": 0,
}Booleans
Boolean values use `true` and `false`
{
"is_enabled": true,
"is_debug": false,
"feature_flag": true,
}
