Compiling Rust to Wasm manually with the LLVM wasm-backend (without Emscripten)

EDIT November 2017: recently the target wasm32-unknown-unknown was added to rustc which uses the LLVM WASM backend and works without Emscripten. This is now the recommended way of generating WASM code from Rust (as it is much easier). Thus, this gist document is pretty much useless now. A great resource on getting started with WASM and Rust is hellorust.com: Setup and Minimal Example.

I cannot believe how Lieferando still has no filter for this. So here is my hacky "filter". It sets the background color of non veggie meals to red (or unsets it if it's already red). I just test for a list of German words. You probably want to adjust that.

Be aware, this is a shitty filter. Probably has lots of false positives and false negatives.

The best way to apply this is to create a new bookmark in your browser and copy the code into the target/URL field. This makes it a bookmarklet.

	* --- Template Meta Program to solve the Partial Knapsack Problem ---
	*
	* This little piece of code solves the partial knapsack problem at compile
	* time. This is not useful in any way. I just wanted to discover the
	* possibilities of template meta programming.
	* Note that this code is absolutly awful. First of all: It's a "pure" template
	* meta program, which is ugly on it's own. Furthermore my code is ugly in
	* particular. The motivation to clean up super-ugly code to get a little bit
	* less ugly code is... not that high.
