Japanese Learn

A Japanese language learning flashcard application built with Rust and Slint.

Overview

• Rust core logic for flashcard management and study mode
• Slint UI for cross-platform desktop and WebAssembly support
• Local JSON/Markdown persistence planned for flashcard data

Prerequisites

• Rust 1.96.0 or later — Install from https://www.rust-lang.org/tools/install
• Slint — Integrated as a Cargo dependency; automatically downloaded during build
• Python 3 — Required for the web version; install and add python3 to your PATH
• wasm-opt — Install with cargo install wasm-opt before using the web build

For detailed setup and troubleshooting, see the official Slint Rust documentation.

Getting Started

1. Install Rust using the official installer from https://www.rust-lang.org/tools/install
2. Clone this repository
3. Run cargo build to build the Window desktop application
4. Run cargo run to launch the Window desktop application

Running

Desktop

• cargo run --bin japanese_learn

This builds and runs the native desktop application using Cargo.

Web

Before running the web version, install the web prerequisites:

• cargo install wasm-opt
• Install Python 3 and ensure python3 is on your PATH

Then run:

• wasm-pack build --release --target web
• python3 -m http.server

This performs wasm-pack build, starts a local web server on port 8000, and you can open your browser at http://localhost:8000/.

Note: the Slint website suggestion to install only wasm-pack is not enough for this project; cargo install wasm-opt is required for the web build.

Project Structure

• Cargo.toml — Rust package manifest
• src/main.rs — application entry point
• ui/main_window.slint — Slint UI definition
