Regex Examples (regexamples)
- Generate: Generates n random strings that match the given regular expression pattern.
- NewGenerator: Compiles a regex pattern into a reusable Generator, avoiding repeated parsing overhead when generating multiple batches.
- Generator.Generate: Generates n matching strings from a pre-compiled Generator.
- Generator.SetSeed: Sets a deterministic seed on the Generator so that subsequent calls produce the same sequence of strings.

Types ¶
type Generator ¶
type Generator struct {
// contains filtered or unexported fields
}
Generator holds a compiled pattern and a random source, and can produce multiple matching strings efficiently.
A Generator is not safe for concurrent use. If you need to generate strings from multiple goroutines, create a separate Generator per goroutine or protect access with a sync.Mutex.
func NewGenerator ¶
NewGenerator compiles pattern and returns a Generator ready to produce matching strings. Returns an error if the pattern is invalid.
