BackportedCompletions
by lidanthedev
BackportedCompletions brings a suggestion box to Minecraft 1.8.9, so chat commands and player names can be completed as the player types.
What it does
Players typing a command or a chat message see a list of matching completions for commands and player names, and can pick one with the arrow keys, the Tab key or a mouse click. Matching can be set to case-sensitive or case-insensitive, and to match the start of a word only. The behavior is adjustable in the mod's options, which lets each player choose how strict the matching should be.
Requests for suggestions are debounced, so the client does not send a new request on every keystroke, which keeps the number of server requests lower. The mod changes nothing on the server side, and it is intended for players who want the newer chat feel on an older version. Installation requires a Forge build for 1.8.9, and the mod works with Smooth Integration.
The only published file targets Forge for 1.8.9, so the mod cannot be used on other loaders or game versions. Since the environment is client-side only, servers do not need it and players can join a server that does not run it. The code is released under the MIT License and is open source, with the source and issue tracker available publicly.

Configurable matching
Case sensitivity and start-only matching can be set so that the list fits how the player types.

How it compares
Among the alternatives, ChatClickClose is the one with the same 1.8.9 target: it is client-side only, released under the MIT License and open source, and it also covers Fabric, Forge and NeoForge across 1.8.9 – 1.21.8. NBT Autocomplete is a client-side only, open source mod under the GNU Lesser General Public License v3.0 only, for Fabric, Forge and NeoForge across 1.16.5 – 26.3, so it does not target 1.8.9. KeyPreset is client-side only and open source under the MIT License, built for 1.20.1 – 1.21.1 on Fabric, Forge and NeoForge.
