# Explanations:
|
|
# cabal2nix, distribution-nixpkgs, jailbreak-cabal, language-nix: These are our packages and we know what we are doing.
|
|
# lsp, lsp-types, lsp-test, hie-bios: These are tightly coupled to hls which is not in stackage. They have no rdeps in stackage.
|
|
# ShellCheck: latest version of command-line dev tool.
|
|
# Agda: The Agda community is fast-moving; we strive to always include the newest versions of Agda and the Agda packages in nixpkgs.
