In the last years I've been asked multiple times about the comparison between raylib and SDL libraries. Unfortunately, my experience with SDL was quite limited so I couldn't provide a good comparison. In the last two years I've learned about SDL and used it to teach at University so I feel that now I can provide a good comparison between both.
Hope it helps future users to better understand this two libraries internals and functionality.
To install fish shell on windows the options are:
Since git bash is based on MSYS2 it seems a good fit to install fish. The problem is that git bash is a lightweight version of MSYS2 which does not include pacman as a package management, used to install fish.
This OS thread has great suggestions on how to solve this problem including using the full MSYS2. But the best solution for me was this answer by Michael Chen which installs pacman on git bash.

Now that Pebble servers are gone, some old components in the SDK need to be patched or replaced so they can fetch what they need from Rebble.
This script downloads and installes everything needed to build projects and also run the emulator.
Was tested on Ubuntu 18.04.2 on WSL.
When compiling client files to webassembly, usually you'll end up with both .js and .wasm files.
By default, most webservers don't know about the wasm MIME type.
You'll likely see the following error:
wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'.
Here is how to add the wasm MIME type (on linux systems, apache + nginx):
Open /etc/mime.types You'll see two columns, media type on the left, file type on the right Add the line application/wasm wasm
