librarianroller
by ticsea
librarianroller is a client-side utility for Minecraft that repeatedly breaks and re-places a lectern so a nearby librarian villager refreshes its enchanted book trades.
What it does
The mod automates the lectern step of librarian trade farming. It breaks and re-places the lectern, which makes the villager restock its offers, and it can work with one, four or six villagers at a time. Targets are set by enchantment and level, so the loop stops only when a wanted book appears. A durability guard stops the axe used for the job before its durability drops below a chosen threshold, which prevents the tool from breaking.
Because the mod is client-side only, the server and other players do not need it, and it changes no server data. Its parameters can be adjusted in a configuration file. Installation requires Cloth Config API, and Mod Menu is optional for opening the settings. Files are published for Fabric, Forge and NeoForge, for 1.20.1, 1.21.1, 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2, and the code is released under the GNU General Public License v3.0 or later, so it is open source.
Key features
Automated lectern loop
Breaks and re-places the lectern on a timed cycle, refreshing the villager's trades without manual clicks.
Enchantment filtering
Desired enchantments and their levels are listed, so the loop is aimed at specific books rather than any trade.
Multi-villager support
Runs with one, four or six librarian villagers at the same time, so several trade pools are refreshed together.
Durability protection
Halts the axe once its durability falls below a set threshold, so the tool is not destroyed mid-farm.
Adjustable configuration
Timing, target enchantments and the durability threshold are changed in a config file.
