Constants

const (
	// ExpansionMax is the default cap on the number of expansion results.
	// TypeScript brace-expansion: EXPANSION_MAX = 100_000
	// Also Options DefaultBraceExpandMax.
	ExpansionMax = 100_000

	// ExpansionMaxLength caps total characters held across all results in
	// the accumulator (CVE-2026-14257 mitigation).
	// TypeScript: EXPANSION_MAX_LENGTH = 4_000_000
	ExpansionMaxLength = 4_000_000
)

Expansion limits matching brace-expansion@5 (used by minimatch).

Functions

func Expand

func Expand(pattern string, max, maxLength int) []string

Expand runs brace-expansion expand(str, {max, maxLength}). Does not validate pattern length or honor nobrace (caller handles that).

func HasSimpleGroup

func HasSimpleGroup(pattern string) bool

HasSimpleGroup is the ReDoS-safe `{…}` pre-check used by minimatch.braceExpand.
