Arch Linux — AUR (yay)

The AUR backend in src/managers/yay.rs wraps an AUR helper (default: yay) using the same interface as the Pacman backend. The AUR helper is configurable — see Configuration.

AUR Helper Configuration

The helper name is read from Config::aur_helper (default: "yay"). Any helper that accepts yay-compatible CLI flags should work:

# ~/.config/trx/config.toml
aur_helper = "paru"

Search

search_aur calls <helper> -Ss <query> and parses the alternating-line output via parse_alternating_lines. Packages receive the provider string "aur".

Package Details

aur_details runs <helper> -Si <pkg> and parses the colon-separated output into a HashMap. The Maintainer, URL, Votes, and Popularity fields typically appear in AUR results.

Install

aur_install runs <helper> -S <packages> via execute_external_command, handing control of the terminal to the helper's interactive output (which typically presents a PKGBUILD review step).

Provider Routing

When the user selects packages for install, ArchManager::install inspects each package name:

#![allow(unused)]
fn main() {
for name in pkgs {
    if name.starts_with("aur/") {
        yay::aur_install(terminal, &[name])?;
    } else {
        pacman::pacman_install(terminal, &[name])?;
    }
}
}

Packages prefixed with aur/ go to the AUR helper; all others go to pacman.
