Errors Package Equivalents

Replace errors package functions for error handling with multilingual support:

Go Standard	fmt Equivalent
errors.New()	Err(message)
fmt.Errorf()	Errf(format, args...)

Error Creation

// Multiple error messages and types
err := Err("invalid format", "expected number", 404)
// out: "invalid format expected number 404"

// Formatted errors (like fmt.Errorf)
err := Errf("invalid value: %s at position %d", "abc", 5)
// out: "invalid value: abc at position 5"

Multilingual Error Messages

For multilingual error messages using dictionary terms that can be translated into multiple languages, see the Translation Guide.

// Using dictionary terms for translatable errors
// Note: requires import _ "github.com/tinywasm/fmt/dictionary"
err := Err("format", "invalid")
// → "format invalid" (in English) or translated based on global language setting

// Force specific language
err := Err(ES, "format", "invalid")
// → "formato inválido"
