This is simple Go parser that uses mapping from Go types to PEG language definitions.
Simple example:
type Hello struct {
Hello string `regexp:"[hH]ello"`
_ string `literal:","`
Name string `regexp:"[a-zA-Z]+"`
}
...
var hello Hello
new_location, err := parse.Parse(&hello, []byte("Hello, user"), nil)Documentation is here: https://godoc.org/github.com/rymis/parse And user-friendly examples and book are placed here.
