Calix

On Arch Linux, installing software means moving from one tool to another: pacman for the official repositories, a helper for the AUR, flatpak for sandboxed packages, and "whatever is lying around" for AppImages. Each has its own output, its own idea of what is installed, and its own path to administrator rights.

Calix brings all of that into a single native application: no embedded web page, no hidden browser. The interface is written in Rust with GPUI — the same foundation as gnosix — and package management in Zig.

This is the most interesting point for anyone funding or evaluating the project. A package manager needs administrator rights: it changes the system. The question is not "are those rights needed?" but "how much code receives them?".

In Calix, the interface, the inventory service and the notification bridge run without privilege. Elevation goes through a single narrow, explicit path, via polkit. The project explicitly forbids sudo, su and doas — including in its installation documentation.

The common thread of these four repositories is topology: making explicit where each thing is, and what that position allows. Calix offers a very concrete version of it.

A package installed from the official repositories and the same name coming from the AUR are not the same object. One is signed by the distribution, the other by a community maintainer. Mixing them in an unlabelled list would be a mistake, not a simplification. So Calix keeps the label, and even versions the document format: a consumer that does not know the version refuses to read it.

The chart comes from a screenshot of Calix on the author's workstation: 1,803 packages, almost all from the official repositories. This is what an ordinary Arch Linux system looks like, seen all at once.

Before v0.3.0, with the log open, the package list shrank to 6.5 pixels high while its own caption kept 260. v0.3.0 wrote down who is entitled to space — and measured it: 170.5 pixels in the same band.

The same release replaced a minimum window size nobody had justified (1024 × 680) with a computed one: a row's five fixed columns, the glyph, room for the name of 90% of a real machine's packages and the folded navigation bar add up to 716 pixels, rounded to 720. The case that failed at 560 pixels is kept in the tests. Measured on the author's machine on October 29, the minimum window is 720 × 520; the release note announces 480 high.

The latest, v0.3.1, is "the release that runs on the machine": the interface moves to the current generation of its graphics library — twenty-four compile errors brought down to zero, and no layout measurement moved. Where the documents and the code disagreed, the documents were corrected.

The most telling work item concerns privilege: a dedicated root helper and finer polkit actions, so the interface asks for exactly the operation it needs — and nothing more.

The repository ranks five work items by value, with no dates:
