# KI18n Crate for Rust
[![Crates.io](https://img.shields.io/crates/v/ki18n)](https://crates.io/crates/ki18n)
[![Documentation](https://docs.rs/ki18n/badge.svg)](https://docs.rs/ki18n/)

## Introduction
KI18n is a cross-platform internationalization framework used by KDE applications. This crate
is meant to allow using KI18n with Rust and [qmetaobject-rs](https://github.com/woboq/qmetaobject-rs) crate.

## Motivation
I love KDE. I have been using it as my primary DE for quite a while. I also like Rust Programming Language.
Currently, it is nearly impossible to use any KDE frameworks from Rust without some C++ FFI. While FFI is
never easy, complexity with C++ is exponentially more than plain C due to the Object-Oriented nature of C++,
which is entirely different from Rust's somewhat functional design.

If possible, I would like the Tier-1 KDE Frameworks to be usable from pragmatic Rust in a somewhat natural
fashion. I am currently interested in KDE frameworks that are usable with QML.

## Requirements
This crate requires KF5I18n to be installed or at least present in the system.
### Ubuntu
```shell
sudo apt install libkf5i18n-dev
```

### Arch Linux
```shell
sudo pacman -S ki18n
```

## Custom Location for KF5I18n
The crate searches from KF5I18n using either the environment variables (`KF_VERSION`,
`KF_INCLUDE_PATH` and `KF_LIBRARY_PATH`) if they are set or uses `kf5-config` to find the paths.

## Features
- `qmetaobject` : Enables some methods that require qmetaobject. Most people will need this.

## Example
```no-run
use cstr::cstr;
use qmetaobject::prelude::*;
use ki18n::klocalizedcontext::KLocalizedContext;

fn main() {
  let mut engine = QmlEngine::new();
  KLocalizedContext::init_from_engine(&engine);
  engine.load_data(r#"
    import QtQuick 2.6
    import QtQuick.Controls 2.0 as Controls
    import QtQuick.Layouts 1.2
    import org.kde.kirigami 2.13 as Kirigami

    // Base element, provides basic features needed for all kirigami applications
    Kirigami.ApplicationWindow {
        // ID provides unique identifier to reference this element
        id: root

        // Window title
        // i18nc is useful for adding context for translators, also lets strings be changed for different languages
        title: i18nc("@title:window", "Hello World")

        // Initial page to be loaded on app load
        pageStack.initialPage: Kirigami.Page {

            Controls.Label {
                // Center label horizontally and vertically within parent element
                anchors.centerIn: parent
                text: i18n("Hello World!")
            }
        }
    }
  "#.into());
  engine.exec();
}
```rust
