CLI11 provides all the features you expect in a powerful command line parser, with a beautiful, minimal syntax and no dependencies beyond C++11. itk-wasm enhances CLI11 with a itk::wasm::Pipeline wrapper to support efficient execution in multiple Wasm contexts, scientific data structures, and lovely colorized help output 🥰.
WebAssembly's origins date back to Alon Zakai's incredible effort to build C++ to JavaScript. In 2015, we demonstrated the power of this technology to make scientific computational sustainable and accessible. Try it -- reproducibility is still possible all these years later, with no installation (or maintenance!) required.
Since that time, Emscripten's capabilities have advanced and been standardized with WebAssembly (Wasm) in the Web Platform. Moreover, Wasm's scope has expanded dramatically with the advent of the WebAssembly System Interface, WASI, and The Component Model.
In this post, adapted from itk-wasm's documentation, we provide a C++ Wasm processing pipeline tutorial that demonstrates how we can write elegant processing pipelines in C++ via itk-wasm's CLI11 command line parser, which provides a rich feature set with a simple and intuitive interface. At the end of this tutorial, you will have built and executed C++ code to Wasm for standalone execution on the command line and in the browser.
The itkImage.h header is ITK's standard n-dimensional image data structure.
