# KI18n Crate for Rust
|
|
[](https://crates.io/crates/ki18n)
|
|
[](https://docs.rs/ki18n/)
|
|
|
|
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 (KF5_I18n_INCLUDE_PATH and KF5_I18n_LIBRARY_PATH) if they are set or just
|
|
searches at /usr/include /usr/library
|
|
|
|
|
|
# Example
|
|
```rust
|
|
use cstr::cstr;
|
|
use qmetaobject::prelude::*;
|
|
use ki18n::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();
|
|
}
|
|
```
