Functions ¶
func ParseTag ¶
func ParseTag(input string, opts ...ParseOption) map[string]string
ParseTag parses a tag string into a map of key-value pairs with configurable separators. By default, it parses comma-separated key=value pairs (e.g., "contains,column=name,operator=eq"). Use ParseOption functions to customize the separator behavior.
Types ¶
type BareValueMode ¶
type BareValueMode int
BareValueMode defines how to treat values without a separator.
const ( // BareAsValue treats bare values as values under DefaultKey (default behavior). // Example: "required,optional" → {"__default": "required"} (optional is ignored with warning). BareAsValue BareValueMode = iota // BareAsKey treats bare values as keys with empty values. // Example: "required,optional" → {"required": "", "optional": ""}. BareAsKey )
type ParseOption ¶
type ParseOption func(*parseConfig)
ParseOption configures the tag parser behavior.
func WithBareValueMode ¶
func WithBareValueMode(mode BareValueMode) ParseOption
WithBareValueMode sets how to treat values without a separator.
BareAsValue (default): Treats bare values as values under DefaultKey. Only the first bare value is kept, subsequent ones are ignored with a warning. Example: ParseTag("required,optional") → {"__default": "required"} (optional ignored)
BareAsKey: Treats bare values as keys with empty values. Multiple bare values are allowed. Example: ParseTag("required,optional", WithBareValueMode(BareAsKey)) → {"required": "", "optional": ""}.
func WithPairDelimiter ¶
func WithPairDelimiter(delimiter rune) ParseOption
WithPairDelimiter uses a single rune to separate pairs.
func WithPairDelimiterFunc ¶
func WithPairDelimiterFunc(fn func(rune) bool) ParseOption
WithPairDelimiterFunc allows custom separator logic for complex cases.
func WithSpacePairDelimiter ¶
func WithSpacePairDelimiter() ParseOption
WithSpacePairDelimiter is a convenient shorthand for space-separated formats commonly used in query strings and CLI arguments.
func WithValueDelimiter ¶
func WithValueDelimiter(delimiter rune) ParseOption
WithValueDelimiter changes the key-value separator (default is '=').
