Parse regular expressions to structs.

Supported conversions

Matches can be parsed into the following field types:

• string
• []byte
• [N]byte
• int/uint/intN/uintN/uintptr
• floatN
• complexN
• bool
• any type that implements encoding.TextUnmarshaler (e.g. time.Time or net.IP).

Example

type Foo struct {
    Bar string
    Baz float64
}

parse, _ := Compile[Foo](`(?<Bar>[a-z]+) (?<Baz>[0-9.]+)`)

foo, _ := parse(`yadda 3.14`)

fmt.Printf("%s/%.3f", foo.Bar, foo.Baz) // Output: yadda/3.140

Overview

Example

parse := Compile[struct {
	RawMatch
	Position
	Foo int
	Bar time.Time
}](`(?P<Foo>[0-9]+)/(?P<Bar>[^\s]+)`)

foo, err := parse("---> 42/2022-02-22T09:00:00Z <---")
if err != nil {
	fmt.Println(err)
	return
}

fmt.Println(foo.Foo)
fmt.Println(foo.Bar)
fmt.Println(foo)
fmt.Println(foo.Position)

Output:

42
2022-02-22 09:00:00 +0000 UTC
42/2022-02-22T09:00:00Z
