How to install vlang/sdl on Windows?

Run the provided `windows_install_dependencies.vsh` script in the cloned repository to download SDL2 libraries, then copy the DLLs to your application directory, as detailed in the Windows section of the README.

vlang/sdl vs other V game libraries?

vlang/sdl is focused on low-level SDL bindings with full API coverage, ideal for direct SDL access in V, while other libraries like V's built-in graphics might offer higher-level abstractions but less control.

Why does vlang/sdl crash with memory access errors?

This often occurs when using V's garbage collector with SDL; avoid the `-d sdl_use_gc` flag and manually manage memory with SDL functions like `sdl.free` to prevent crashes, as noted in the README.

Can I use SDL3 with vlang/sdl?

Yes, dedicated branches for SDL3 are available in the repository; check the README for SDL3 instructions and use the appropriate branch, though it may require extra steps like the `sdl2-compat` layer.

How to handle input events in vlang/sdl?

Use SDL's event system via bindings like `sdl.PollEvent` to process keyboard, mouse, and gamepad inputs in V, similar to C SDL workflows, with examples provided in the tVintris demo.

What are the system dependencies for vlang/sdl on Linux?

Install SDL2 development libraries specific to your distro, e.g., `libsdl2-ttf-dev` on Ubuntu or `SDL2-devel` on Fedora, as listed in the Dependencies section, before using the module.

What is sdl?

sdl is a V programming language module that provides official bindings to the SDL2 and SDL3 libraries. It enables V developers to create multimedia applications, games, and interactive software by exposing SDL's functionality for window management, graphics rendering, input handling, and audio playback. The module supports multiple SDL versions and platforms while aiming for full API coverage.

Target Audience

V programmers who need to build cross-platform multimedia applications, games, or interactive tools requiring graphics, audio, and input handling. It's particularly useful for developers familiar with SDL who want to use it within the V ecosystem.

Value Proposition

It offers official, well-maintained bindings with extensive SDL API coverage, support for both SDL2 and SDL3, and cross-platform compatibility. Unlike generic bindings, it's tailored for V's syntax and memory model, with version-matched branches and clear installation guidance.

Overview

Official SDL2 & SDL3 bindings for V

Use Cases

Best For

Creating 2D games in V with graphics and audio
Building cross-platform multimedia applications in V
Handling input from keyboards, mice, and gamepads in V programs
Developing graphical demos or tools with window management in V
Porting existing SDL-based projects to the V language
Learning game development in V with a proven multimedia library

Not Ideal For

Projects needing automatic dependency management without manual version matching
Teams relying on garbage collection for memory safety without manual intervention
Developers targeting non-desktop platforms like mobile or embedded systems
Scenarios requiring seamless integration with SDL1.x or minimal setup overhead

Pros & Cons

Pros

Complete SDL API Coverage

Strives for 100% support of both SDL2 and SDL3 APIs, ensuring V developers can leverage all multimedia features without gaps, as stated in the README.

Cross-Platform Reliability

Works on Linux, macOS, and Windows with detailed installation guides for each OS, making it practical for desktop-focused applications.

Version-Matched Branches

Provides git branches aligned with specific SDL2 releases (from 2.0.8 upward), allowing precise compatibility and easier maintenance, as highlighted in the project navigation.

Flexible Memory Management

Offers both manual memory management using SDL functions and optional garbage collection (with caveats), catering to different performance and simplicity needs.

Cons

Installation Complexity

Requires manual cloning of specific git branches, running setup scripts, and system-level SDL2 library installation, which is more involved than integrated package managers.

Garbage Collector Instability

Using V's default GC with SDL objects can cause runtime crashes, forcing developers to manage memory manually or use compile-time flags, as admitted in the README notes.

Limited Platform Support

Only supports Linux, macOS, and Windows, excluding other platforms where SDL is used, such as mobile or embedded systems, limiting its cross-platform appeal.
