Go library for generate serial numbers according to rules.
This library is useful for generating serial numbers in human-readable format and for generating dummy data (e.g., email addresses, names of people, etc.).
go get -u github.com/kenkyu392/go-sn

// Create a generator with arbitrary rules.

// You can create your own rules.

// Use rules for numbering and padding.
// You can also do customized numbering.
// -> (&rule.Counter{Start: 2, Size: 2, Padding: 4}).NumberingWithPadding(),
rule.NumberingWithPadding(4),
)
// You can change the delimiter.
g.Delimiter = "_"

}To generate a dummy email address, you may use the following:
g := sn.NewGenerator(
rule.Mixin(
rule.RandomAlphabet(4),
rule.String("."),
rule.RandomAlphabetAndNumeric(6),
),
rule.RandomList(
[]string{
"example.com",
"example.net",
"example.org",
},
),
)
g.Delimiter = "@"
for i := 0; i < 5; i++ {
fmt.Println(g.String())
}
