func Parse ¶

func Parse(s, key string) (string, bool, error)

Parse extracts the value for key from a clib tag string. Returns the unquoted value and true if found, or "" and false otherwise. Bare keys (no '=') return "" and true.

Format: comma-separated entries, values optionally single-quoted:

"negatable,group='Filters',placeholder='repo'"

func Split ¶

func Split(s string) ([]string, error)

Split splits a clib tag on commas, respecting single-quoted values.

func SplitCSV ¶

func SplitCSV(s string) []string

SplitCSV splits s on commas, trims whitespace from each element, and returns the resulting slice. Returns nil for empty input.

Empty fields are preserved deliberately. An empty entry can be a valid enum member - e.g. a `enum:",json,wide" default:""` flag whose empty value is the default - and, crucially, keeping empties keeps Enum index-aligned with the separately-split EnumHighlight/EnumTerse slices. Empties are hidden from help output later by dropEmptyEnum in help/render.go, which drops the paired highlight in lockstep.
