The development shell inherited build dependencies but Cargo-built tray
binaries lack the installed package's wrapper. AppIndicator was present in
the store yet its dlopen lookup failed because the runtime library path was
missing. The same problem affected dynamically loaded graphics libraries.
Expose the package's existing trayRuntimeLibs through passthru and reuse that
list in mkShell packages and its LD_LIBRARY_PATH hook. Include the existing
NixOS OpenGL driver path and preserve any caller-supplied library paths.
The development shell and installed tray now share one dependency list.
Document direct execution of Cargo-built tray binaries inside nix develop.
No agent, protocol, package version or system configuration changes.
Validation on Linux:
- Reproduced the missing AppIndicator dlopen failure before the change.
- Loaded libayatana-appindicator3.so.1, libxkbcommon-x11.so.0, libEGL.so.1,
libGL.so.1 and libwayland-client.so.0 inside the updated shell.
- Verified AppIndicator still loads with an inherited LD_LIBRARY_PATH and
that the existing value is preserved. The first probe used an older host
Python with an incompatible glibc; probes using Python from the pinned
nixpkgs input passed.
- Evaluated the x86_64-linux CLI package and shared runtime dependency list,
and the aarch64-linux development shell; no aarch64 execution claimed.
- nixfmt --check flake.nix nix/package.nix
- cargo fmt --all -- --check
- cargo clippy --locked --workspace --all-targets -- -D warnings
- cargo test --locked --workspace --all-targets: 566 passed, 3 ignored
Cargo checks ran through nix develop, with TSUNAGI_CONTROL_SOCKET unset for
Clippy and tests. Existing agent and tray processes were not restarted.
The README is now a landing page: the idea (a mesh VPN with no server, joined
with a network name and a secret), install and platform tables, exit nodes,
and a short build section. Implementation detail stays in docs/.
The flake builds tsng and the tray from source and ships a NixOS module
(services.tsunagi). Dist install notes now show the real `join -n -s` syntax,
and two links that pointed into the old README are redirected.
