Colfer is a powerful binary serialization format designed for speed and size, inspired by Protocol Buffers. It allows for efficient marshalling and unmarshalling of data structures, making it ideal for applications requiring fast data handling. This guide will walk you through the process of using Colfer, including installation, usage, and troubleshooting.

Getting Started with Colfer

To effectively use Colfer, you’ll first need to get the compiler up and running. You can either download a prebuilt compiler or build it from source. Here’s how:

• Download a Prebuilt Compiler: Head over to the release page and download the prebuilt binary that fits your operating system.
• Build from Source: If you prefer building from source, run the following command:

go get -u github.com/pascaldekloe/colfer/cmd/colf

• Homebrew Installation (For macOS Users): Open your terminal and run the command:

brew install colfer

Compiling Schema with Colfer

Once you have Colfer installed, you can start compiling your schema files. Here are some common commands:

colf -b src -s 2048 -l 96 C io.colf

The command above compiles the schema defined in the io.colf file into C code while applying specified limits.

colf -p com.example.model -x com.example.io.IOBean Java io.colf

This command compiles the schema into Java code, specifying a package prefix and superclass.

Understanding the Code with an Analogy

Think of using Colfer much like preparing ingredients for a dish in a kitchen. When you create a schema file (.colf), you are essentially writing a recipe for what your data should look like. The colf command acts as your head chef, taking these recipes (schema) and gathering the necessary ingredients (data types) to create the final dish (compiled code). Whether you’re whipping up a C, Go, Java, or JavaScript dish, Colfer ensures that everything is prepared quickly, efficiently, and with minimal fuss.

Colfer Features at a Glance

• Simple and straightforward usage
• No dependencies other than the core library
• Faster and smaller than many competitors
• Robust against malicious input
• Supports a maximum of 127 fields per data structure
• Framed and suitable for concatenation/streaming

Troubleshooting Common Issues

While using Colfer, you might encounter some issues. Here are some troubleshooting tips:

• No output generated: Ensure you have the correct file paths and that your schema files are properly formatted.
• Compilation errors: Check if you are using unsupported features in your schema, such as enumerations, which are not supported by Colfer.
• Memory issues: Adjust the limits for serial byte sizes and list elements using the -s and -l options.
