Generate locales from JSON files

Easily create strong properties and methods from JSON localized translations, with optional arguments.

How to use:

Install latest package EntityLocalizer https://www.nuget.org/packages/EntityLocalizer/

Add this to .csproj.

<Project> <Target Name="CodeGen" BeforeTargets="BeforeBuild;BeforeRebuild"> <EslGeneratorTask InputPath="./StaticResources/Locales" OutputPath="./GeneratedResources/Locales/" OutputNamespace="Entity" /> </Target> </Project>

• InputPath is the directory from where to load the locales,
• OutputPath is the directory where the output C# resource file will be generated.
• OutputNamespace is the namespace for the generated C# file.

Once you have setup your project, you can add locales by creating *.loc.json files, the file names must end in .loc.json. Format below:

{ "HelloWorld": { "EN": "Hello generated world!", "FR": "Bonjour monde!" }, "Login": { "EN": "Log in", "FR": "Connexion", "?": "Default case override" } }

Then you just run a build on consumer project, you can now access your locales/translations via C# using the following:

var locales = new EntityLocales() { InstanceLanguage = "EN" }; Console.WriteLine(locales.HelloWorld); // outputs "Hello generated world!"

If you want to generate translations that accept parameters, you can do the following in the JSON file:

{ "LocaleWithArgument": { "args": [ "string:name", "number:amount", "string:currency" ], "EN": "Welcome {0}, your bill is of {1} {2}", "FR": "Bienvenue {0}, votre facture est de {1} {2}" } }

Only the 2 following types are supported: string and number. Supply a mandatory method argument name like so: [type]:[argName]

You can then access the locales and supply arguments like so:

var translated = locales.LocaleWithArgument("Jacob", 129.99m, "$"); // outputs "Welcome Jacob, your bill is of 129.99 $"

Use in JS/TS

type Locale = 'EN' | 'FR' type I18nSource = Record<string, Record<Locale, string>> const i18nSource = { HomeWelcome: { EN: 'Welcome to App', FR: 'Bienvenue', }, Foo: { EN: 'Foo EN', FR: 'Foo FR', }, } satisfies I18nSource let currentLocale: Locale = 'EN' const translation = {} as Record<keyof typeof i18nSource, string> for (const key in i18nSource) { Object.defineProperty(translation, key, { get: () => i18nSource[key as never][currentLocale], }) } console.log(translation.HomeWelcome) console.log(translation.Foo) currentLocale = 'FR' console.log(translation.HomeWelcome) console.log(translation.Foo)
