App Localizator

A powerful tool that provides the ability to translate text on the fly, which can be useful when developing RestAPI with multilingualism

Instalation

dotnet add package OftobTech.AppLocalizator

or via Nuget tools in Visual Studio

Basic usage

Create Lang folder in root of published project

Inside this folder you can create translation files, for example

en.txt
jp.txt
ar.txt

Then you cant use this tools in code

using OftobTech.AppLocalizator;

OftobTech.AppLocalizator.Reader.UpdateLangs();

var message = T.Compile("[Text to transalete]");
Console.WriteLine( message );

Language file format

[sentence for translate] : [translated sentence]
[sentence for translate] : [translated sentence]
[sentence for translate] : [translated sentence]
....

Each translated sentence must end with a transition to a new line, the text separator for the translation and the translated text is a colon

Configuretion

The library also supports minimal configuration, which allows you to configure the default language and the location of the folder with translation files relative to the project.

If the config file has not been created, the default one is taken:

# The default language will be used if it 
# was not passed an additional parameter when using the library
DefaultLang: en

# The address of the language files can be either relative or absolute
LangsFilesPath: Langs

You can manually create the file data using the following path config/lang.conf

Or call the following construction:

using OftobTech.AppLocalizator;

OftobTech.AppLocalizator.Config.PublishConfig();

Which will automatically create the default config

Changing the language during execution

To change the language during the execution of the program, you need to call the setLang(string lang) method

using OftobTech.AppLocalizator;

T.setLang(item.DeviceLanguage);

It can also be called every time before translation, (it is worth considering that the last exposed language is remembered)

using OftobTech.AppLocalizator;

T.setLang(item.DeviceLanguage).Compile("[Text to transalete]");

Line translations with parameters

To translate strings with parameters in the translation file, you need to embed parameters into the translation string, this is done by wrapping some parameter identifier in curly brackets Example:

Hello : Hello {parametr_1}  {parametr_2}

To translate such a string into the Compile method, the for Replace attribute passes an object with the Dictionary<string, string> type, where the key is the parameter identifier (without curly brackets) and the value needs to be replaced with

Example

using OftobTech.AppLocalizator;

var params = new Dictionary<string, string>(){
    {"parametr_1", "beautiful"},
    {"parametr_2", "world!"},
}

T.setLang(item.DeviceLanguage).Compile("Hello", params);

Strict mode

The library supports 2 translation modes normal mode and timing, in normal mode, if no suitable strings were found in the translation files, the string that was passed is returned, in strict mode, if the translation string is not found, NULL will be returned

Example

using OftobTech.AppLocalizator;

T.Compile("[Text to transalete]", true);
/// OR
T.Compile("[Text to transalete]", params ,true);

Updating language files

There are cases when there is a need to add or update language files, but you cannot restart the application, then the UpdateLangs() method can come to your aid, which allows you to update translations in the application's memory on the fly

using OftobTech.AppLocalizator;

OftobTech.AppLocalizator.Reader.UpdateLangs();
