Features

Configuration String Parser

Parse configuration strings into nested dictionaries with automatic type conversion.

from kiarina.utils.common import parse_config_string

# Basic usage
config = parse_config_string("cache.enabled:true,db.port:5432")
# Result: {"cache": {"enabled": True}, "db": {"port": 5432}}

# Flag support (no value)
config = parse_config_string("debug,verbose,cache.enabled:true")
# Result: {"debug": None, "verbose": None, "cache": {"enabled": True}}

# Array indices support
config = parse_config_string("items.0:first,items.1:second")
# Result: {"items": ["first", "second"]}

# Custom separators
config = parse_config_string(
    "key1=val1;key2.sub=42", 
    separator=";", 
    key_value_separator="="
)
# Result: {"key1": "val1", "key2": {"sub": 42}}

Type Conversion

Values are automatically converted to appropriate types:

• "true", "True" → bool(True)
• "false", "False" → bool(False)
• Numeric strings ("1", "0", "-5", "3.14") → int or float
• Other strings → str

Nested Keys

Use dot notation for nested structures:

config = parse_config_string("database.host:localhost,database.port:5432")
# Result: {"database": {"host": "localhost", "port": 5432}}

Array Indices

Use numeric keys for array structures:

config = parse_config_string("users.0.name:Alice,users.0.age:30,users.1.name:Bob")
# Result: {"users": [{"name": "Alice", "age": 30}, {"name": "Bob"}]}

API Reference

parse_config_string(config_str, *, separator=",", key_value_separator=":", nested_separator=".")

Parse configuration string into nested dictionary.

Parameters:

• config_str (str): Configuration string to parse
• separator (str, optional): Item separator. Default: ","
• key_value_separator (str, optional): Key-value separator. Default: ":"
• nested_separator (str, optional): Nested key separator. Default: "."

Returns:

• dict[str, Any]: Parsed configuration dictionary

Examples:

# Basic usage
parse_config_string("key1:value1,key2:value2")
# {"key1": "value1", "key2": "value2"}

# Nested keys
parse_config_string("cache.enabled:true,db.port:5432")
# {"cache": {"enabled": True}, "db": {"port": 5432}}

# Flags (no value)
parse_config_string("debug,verbose")
# {"debug": None, "verbose": None}

# Custom separators
parse_config_string("a=1;b=2", separator=";", key_value_separator="=")
# {"a": 1, "b": 2}
