Odin Language Examples

To test the server, run the client package in a separate terminal window. Once the client is running, you can type messages into the terminal to send them to the server.

To terminate the client session, type an empty line and press Enter (\r\n or \n).

odin run client

To run this example, ensure you have the following installed:

• Odin Compiler: The latest stable version.
• Terminal: A command prompt or terminal emulator to execute the commands.

To run an example from this repository, clone the repository and navigate into the specific example's directory. Most examples can be executed using the odin run . command. Note that some examples may contain a local README file with specific instructions or additional requirements.

# Navigate to an example directory
cd path/to/example

# Run the example
odin run .

The Raylib examples in this repository mirror the structure of the official Raylib examples. To ensure correct resource loading and execution, you must follow two requirements:

1. Run from the example's directory: You must cd into the specific subdirectory containing the example before running the command.
2. Use the -file flag: You must pass the -file flag to the odin run command.

Example for running shaders/shaders_mesh_instancing.odin:

cd shaders
odin run shaders_mesh_instancing.odin -file

To compile and execute the Vulkan triangle example, use the odin run command from within the example directory.

odin run .

To execute the basic Odin features demonstrated in this example, navigate to the absolute_beginners directory in your terminal and use the odin run command. Note that the output is designed to be read alongside the source code in 1_main.odin to understand the fundamental programming concepts being demonstrated.

odin run .

The example uses pre-compiled SPIR-V shaders (vert.spv and frag.spv). If you modify the source shader files (shader.vert or shader.frag), you must recompile them using glslc (part of the Vulkan SDK) before running the Odin code.

glslc shader.vert -o vert.spv
glslc shader.frag -o frag.spv

Because the example involves a website calling Odin procedures via WASM, you must serve the web directory using a local web server.

1. Navigate to the web directory:

cd web

2. Start a web server using one of the following methods:

Using Python:

python -m http.server

Using Node.js (npx):

npx http-server -p 8000 .

3. Open your browser and visit http://localhost:8000 (or the port specified by your server).

To build an Odin program targeting js_wasm32, use the provided build scripts. These scripts compile the WASM module and automatically copy the required odin.js file from the core Odin library into your project directory.

• Windows: Run build.bat
• macOS / Linux: Run build.sh

./build.sh

If your project uses SDL2 libraries installed via Homebrew, you must provide the linker with the path to the Homebrew library directory using the -extra-linker-flags flag during the build process.

odin build . -extra-linker-flags:"-L/opt/homebrew/lib"

Windows manifests (metadata for UAC, DPI awareness, or visual styles) can be embedded into an executable using a .rc (resource script) file. To embed a manifest as a regular resource, use the RT_MANIFEST type (numeric value 24) and assign the main application manifest the resource ID 1.

# Compile the project including the resource script
odin build . -resource:resource.rc

To start the UDP Echo Server, navigate to the example directory and use the Odin compiler to run the server package. The server will listen for incoming UDP packets and echo the received data back to the client.

Requirements:

• Odin Compiler (latest stable version)
• A terminal or command prompt

odin run server
