Languages changes: the only new language feature is that you can now have antiquotations in paths, e.g. ./${foo} instead of ./. + foo.

2.4 release notes

This should go in basics/strings or the appropriate topic.

I am adapting the expressions in this list:
https://github.com/adambard/learnxinyminutes-docs/blob/74ccc905616e648b443f68fe1e96c5a64449290c/nix.html.markdown

how to contribute a snippet

1. extract the expressions from a section into a file named by that category
   • create the directory if it does not exist
2. open a PR with that example

my opinionated tips

• Try to keep the expressions as "simple as possible but no simpler".
• Avoid comments. These examples are so brief that we want to encourage focus on the syntax not an interpretation of the syntax.

Given this is a community project that wants invovlement, I need to spend some time writing a minimally viable contributing guide.

• what are the project goals?
• what do ideal contributions look like?
• who reviews the contributions?
• What is the technical design of this repository and how does it affect my contribution?
  • I want to add nixpkgs-fmt --check to all nix files. That may result in things like nix-community/nixpkgs-fmt#266
