LAAT is a CLI tool for generating Arma 3 Aux mods from simpler TOML configuration files.
The LAAT Devlopment team is not resposible for any mods or content uploaded to the Steam Workshop using LAAT. It is a tool hoping to ease the Arma 3 mod development process, not make it easier to steal other people's copyrighted works.
I ran an Arma 3 unit for close to 6 months. At our peak we had around 50 members, each of whom would, over time, get their own custom armor added to our mod. Initially it was easy to handle the demand, make a texture, convert from png > paa, and write the nessecary configuration. However, after reaching a critical mass, the requests became too much for one developer to handle. That unit ultimately failed due to this issue.
LAAT aims to fix that, by automating as much of the Arma 3 Aux Mod development process as possible, all while-adhering to insdustry-standard software engineering practices in the process.
With LAAT you can use CI/CD to automate releases and updates to your mod, you have deterministic builds, and most importantly, you have much less code to mantain.
git clone https://github.com/ajmwagar/laat
cd laat
cargo install --path .Create a new LAAT project with laat init
laat init -p myproject -a Avery Wagar
Build your Arma 3 Mod with laat build
Pack your Arma 3 Mod into PBOs with laat pack
Create a keypair with laat keygen <name>
Sign your PBOs with laat pack --sign or laat sign
Release to the Steam workshop with laat release -u <steam user> -p <steam pass> -g <steam guard code>
Since LAAT, by-default, doesn't require any extra tooling, you can run it in GitHub actions and automatically build and release your mod to the Steam Workshop.

An example file looks like this:
prefix = "17th"
name = "17th Infantry Division"
author = "Pvt. Wagar"
# Enable the following plugins
plugins = [
"music",
"addons",
"kits"
]
[pack] # PBO packing settings
excludes = ["*.png"]
include_folders = []
header_extensions = []
[release]
workshop_id = 0000000 # Steam Workshop Item ID
[kits]
file = "./kits.toml"A LAAT Project might look like the following:
.

The development workflow with LAAT adds a new step.
We call it the "build" step, which comes before PBO packing.
Think of the "build" step as another developer who is working on the project with you. It will generate code and addons and add them to the build folder.
The workflow for people who are building normal addons doesn't change, However, we have removed the P:/ drive.
The steps in the pipeline are as follows:
build: LAAT generates your addonspack: LAAT usesarmake2to pack your addons into PBOs.sign: LAAT signs your PBOs using your.biprivatekeyfile.release: LAAT usedsteamcmdto upload your mod to the Steam Workshop.
Plugins are what take your assets and configuration file, and turn them into valid Arma 3 Mod Addons (i.e. the things you build into PBOs)
Currently there are only a few plugins, but many more are planned. If you'd like to see a plugin or certain Arma 3 process automated, please open an issue.
The addons plugin is the most trivial. It takes all of the existing Arma 3 Addons in your addons folder and copies them into the build folder.
This enables you to use LAAT as much or as little as you'd like, by mantaining support for the existing Arma 3 Mod format and tooling.
The missions plugin aims to fix the pain-points associated with mantaining server mission files, and any compositions that are needed across all files.4
You can customize the global offset using composition_offset or specify a per-map offset for your composition.
To get started, add the following to your LAAT.toml
[missions]
addon_name = "Missions"
composition = "./assets/compositions/Skybase"
# X, Y, Z
composition_offset = [0, 0, 0]
ignore_center = true
respawn_delay = 2 # 2 seconds
mission_name = "LAATMission"
maps = [
"Altis",
"Stratis",
"Tanoa",
["Malden", [200, 500, 200]]
]and make sure you add the missions plugin to your plugins section:
# Enable the following plugins
plugins = [
# ...
"missions" # ADD THIS ONE!
]Now, assuming your Skybase composition floats above the air a bit, and has proper respawn points, and playable soldiers, you'll be greeted with functional mission files for each of the listed maps.
The music plugin generates a Music addon from your assets/music folder. It will generate the proper CfgMusic and CfgMusicClass entries to expose the songs of your choosing in the Zeus Play Music action.
The music plugin searches your assets/music folder for any .ogg files or subfolders. It will create a CfgMusicClass for each of the subfolders, and a CfgMusic entry for each of the .ogg files.
For example a LAAT project with the following format:
assets/music
├── 80s
│ ├── Danger_Zone.ogg
│ ├── Dont_You_Want_Me.ogg
│ ├── Enjoy_The_Silence.ogg
│ ├── Mad_World.ogg
│ ├── Psycho_Killer.ogg
│ ├── Sunglasses_At_Night.ogg
│ ├── Take_On_Me.ogg
│ ├── Tom_Sawyer.ogg
└──└── True_Survivor.ogg
Would generate the following addon:
Music
├── config.cpp
└── data
└── Music
├── Danger_Zone.ogg
├── Dont_You_Want_Me.ogg
├── Enjoy_The_Silence.ogg
├── Mad_World.ogg
