      Create a feature that allows us to easily locally maintain AUR PKGBUILDs on our own within Shelly. All it needs to do is something similar to paru -G or yay -G by downloading the PKGBUILD from AUR, then (when requested) pinging the software's own repository from the source inside…

    3. [Feature Request] Sanitize progress outputClosed

      When installing/removing/updating packages, the output in the progress modal has many debug lines and separate lines for progress percentage points. All this makes for a wall of text difficult to navigate and peruse in a meaningful way. A pacman-like CLI behaviour where…

    7. Option to edit PKGBUILD before buildingOpen

      I would like the option to be prompted for whether I want to edit the PKGBUILD. VCS PKGBUILDs on the AUR are often outdated in small ways that prevents a build from succeeding. An option to edit the PKGBUILD before building is thus very convenient.

    Shelly on CachyOS: questions

    Is Shelly in the official CachyOS repo?

    Yes. The shelly package is in the cachyos repo, version 3.1.10-1, built 2026-10-30. Install it with sudo pacman -S shelly.

    Do I need an AUR helper for Shelly?

    No. It comes from the cachyos repo, so plain pacman installs and updates it, and sudo pacman -Syu keeps it current.

    What is the Shelly command?

    The package installs shelly, shelly-flatpak-integrate, shelly-key, shelly-notifications and shelly-ui.
