+# Zellij plugins
+
+Zellij offers a Webassembly / WASI plugin system, allowing plugin developers to
+develop plugins in many different languages. Currently, nixpkgs focuses only on
+Rust plugins (the majority of them).
+
+Most of the plugins were generated using `nix-init` on [awesome-zellij].
+Excluded plugins from that list (should be packaged later anyway):
+
+- [bar-theme-config](https://github.com/allisonhere/zellij-bar-theme-config): not a plugin, but a separate application
+- [fzf-zellij](https://github.com/k-kuroguro/fzf-zellij): [closed source](https://github.com/k-kuroguro/fzf-zellij/issues/1)
+- [gitpod-zellij](https://github.com/ona-samples/gitpod.zellij): not a plugin, but a separate application?
+- [opencode-zellij-namer](https://github.com/24601/opencode-zellij-namer): written in TypeScript, not Rust
+- [theme-configurator](https://rosmur.github.io/zellij-theme-configurator/): not a plugin, but a separate application
+- [yazelix](https://github.com/luccahuguet/yazelix): written in Nushell
+- [zeco](https://github.com/julianbuettner/zeco): not a plugin, but a separate application?
+- [zellij-load](https://github.com/Christian-Prather/zellij-load): has daemon, so that needs to be packaged too
+- [zellij-vscode-toolkit](https://github.com/atoolz/zellij-vscode-toolkit): not a plugin, but a VSCode plugin
+- [zellix](https://github.com/EmeraldPandaTurtle/zellix): written in Nushell
+- [zj-quit](https://github.com/cristiand391/zj-quit): archived
+- [zj-status-bar](https://github.com/cristiand391/zj-status-bar): archived
+- [zrw](https://github.com/ivoronin/zrw): written in Go

+
+## Specifying runtime dependencies
+
+Runtime dependencies are packages, that will be used by the plugin inside
+a Zellij session. Those are specified in `passthru.runtimeDeps` attribute from
+`pkgsBuildBuild` attrset.
+
+Since we compile all plugins on WASI, everything that the plugin gets as
+derivation arguments are also get compiled for WASI. However, `coreutils` is
+not available on WASI and so is the vast majority of packages. This is why
+runtime dependencies need to be specified from `pkgsBuildBuild` attrs set
+(which points to the user's system).
+
+```nix
+# assume we build the plugin on a x86_64-linux machine
+{
+  lib,
+  fetchFromGitHub,
+  rustPlatform,
+
+  # these will be compiled for WASI, not x86_64-linux!
+  just,
+  bacon,
+  # but pkgsBuildBuild points to x86_64-linux
+  pkgsBuildBuild,
+}:
+rustPlatform.buildRustPackage (finalAttrs: {
+  pname = "jbz";
+  version = "0.39.0";
+
+  src = fetchFromGitHub {
+    owner = "nim65s";
+    repo = "jbz";
+    tag = "v${finalAttrs.version}";
+    hash = "sha256-3n3Bv3YDb1+MYJTTAmMkIgGY7kX9IVUoDNV4c/n0Ydo=";
+  };
+
+  cargoHash = "sha256-U+P2LlhmXwaZy2a2eigrg545HTuV1T01jZfUOEUQ5+w=";
+
+  # this is the only way how to specify dependencies
+  passthru.runtimeDeps = with pkgsBuildBuild; [
+    bacon
+    just
+  ];
+
+  meta = {
+    description = "Display your Just commands wrapped in Bacon";
+    homepage = "https://github.com/nim65s/jbz";
+    changelog = "https://github.com/nim65s/jbz/releases/tag/${finalAttrs.src.tag}";
+    license = lib.licenses.mit;
+    maintainers = with lib.maintainers; [ PerchunPak ];
+  };
+})
+```
+
+If you are wondering why `pkgsBuildBuild` is named like that, refer to
+[the docs on cross-compilation](https://nixos.org/manual/nixpkgs/unstable/#possible-dependency-types).
