README

spvalidator

spvalidator is a small validation library for Go with direct function-call validators.

package main

import "github.com/yorukot/spvalidator"

func main() {
	if err := spvalidator.Email("user@example.com"); err != nil {
		panic(err)
	}
}

Validators return nil on success and *spvalidator.ValidationError on failure.

if err := spvalidator.Required(""); spvalidator.IsValidationError(err) {
	// handle validation error
}

String values can also use a fluent validation chain.

value, err := spvalidator.String("  123e4567-e89b-12d3-a456-426614174000  ").
	TrimSpace().
	Required().
	Max(36).
	UUID().
	Value()

Non-string values can use Any.

err := spvalidator.Any(21).
	Required().
	Gte(18).
	Lte(120).
	Err()

Field validators use exported struct field paths.

type Signup struct {
	Password string
	Confirm  string
}

_ = spvalidator.EqField(Signup{"secret", "secret"}, "Password", "Confirm")

The package is independently implemented and aims for practical validation coverage for the supported tags. Very broad standards such as postcode formats, BCP 47, HTML detection, cron syntax, and RFC-perfect URL/domain parsing use documented practical checks rather than exhaustive standard conformance.
