Documentation

Overview

Package i18n helps with internationalization of registered messages.

Example

package main

import (
	"fmt"

	"github.com/aureliar8/ttn-fork/pkg/i18n"
)

func main() {
	i18n.Define("welcome_message", "Welcome, {name}!")

	fmt.Println(i18n.Format("welcome_message", "en", map[string]interface{}{"name": "Alice"}))

}

Output:

Welcome, Alice!

Variables

var Global = make(MessageDescriptorMap)

Global registry.

Functions

func Format

func Format(id, language string, data map[string]interface{}) (msg string)

Format a message from the global registry in the given language.

Types

type MessageDescriptor

type MessageDescriptor struct {
	Translations map[string]string `json:"translations,omitempty"`

	Description struct {
		Package string `json:"package,omitempty"`
		File    string `json:"file,omitempty"`
	} `json:"description,omitempty"`
	// contains filtered or unexported fields
}

MessageDescriptor describes a translatable message.

func Define

func Define(id, message string) *MessageDescriptor

Define a message in the global registry.

func Get

func Get(id string) *MessageDescriptor

Get returns the MessageDescriptor of a specific message from the global registry.

func (*MessageDescriptor) Format

func (m *MessageDescriptor) Format(language string, data map[string]interface{}) (msg string)

Format a message descriptor in the given language.

func (*MessageDescriptor) Load

func (m *MessageDescriptor) Load() error

Load the messages

func (*MessageDescriptor) SetSource

func (m *MessageDescriptor) SetSource(skip uint)

SetSource sets the source package and file name of the message descriptor. The argument skip is the number of stack frames to ascend, with 0 identifying the caller of SetSource.

func (*MessageDescriptor) String

func (m *MessageDescriptor) String() string

func (*MessageDescriptor) Touched

func (m *MessageDescriptor) Touched() bool

Touched returns whether the descriptor was touched (i.e. it is still used).

func (*MessageDescriptor) Updated

func (m *MessageDescriptor) Updated() bool

Updated returns whether the descriptor was updated.

type MessageDescriptorMap

type MessageDescriptorMap map[string]*MessageDescriptor

MessageDescriptorMap is a map of message descriptors.

func ReadFile

func ReadFile(filename string) (MessageDescriptorMap, error)

ReadFile reads the descriptors from a file.

func (MessageDescriptorMap) Cleanup

func (m MessageDescriptorMap) Cleanup() (deleted []string)

Cleanup removes unused message descriptors.

func (MessageDescriptorMap) Define

func (m MessageDescriptorMap) Define(id, message string) *MessageDescriptor

Define a message.

func (MessageDescriptorMap) Get

func (m MessageDescriptorMap) Get(id string) *MessageDescriptor

Get returns the MessageDescriptor of a specific message.

func (MessageDescriptorMap) MarshalJSON

func (m MessageDescriptorMap) MarshalJSON() ([]byte, error)

MarshalJSON marshals the descriptors to JSON.

func (MessageDescriptorMap) Merge

func (m MessageDescriptorMap) Merge(other MessageDescriptorMap)

Merge messages from the given descriptor map into the current registry.

func (MessageDescriptorMap) Updated

func (m MessageDescriptorMap) Updated() (updated []string)

Updated returns updated message descriptors.

func (MessageDescriptorMap) WriteFile

func (m MessageDescriptorMap) WriteFile(filename string) error

WriteFile writes the descriptors to a file.
