Using smithy4s-curl to call smithy4s-defined services from Scala Native using libcurl

https://github.com/neandertech/smithy4s-curl

This scala-cli script has two entrypoints, so you can produce two binaries from it - one using curl, and one using http4s Ember.

Because native dependencies are required for both entrypoints, I prefer to build them using my sn-vcpkg CLI:

To produce a binary using curl:

$ sn-vcpkg scala-cli curl --rename curl=libcurl -- package . -f -o ./native-curl -M helloCurl

Render a yak shaving page to keep track of your side projects

This small script exists only to render a HTML page for the various yaks you are working on.

scala-cli run yak-render.scala -- sample-projects.yml > index.html
