Download StrongDMM

StrongDMM is an alternative yet robust map editor for BYOND.

It was built with the idea to create a more flexible, fast and extensible tool, than BYOND built-in map editor. The editor has same features DM has, but provides much more and improves general map editing experience.

The editor provides a bunch of new features:

• TGM support with built-in map merger (no need to use external scripts and pre-commit hooks);
• Almost instant environment open;
• Custom layers filter;
• Built-in screenshot tool;
• Smooth zoom-in/zoom-out;
• Robust "Search";
• Improved shortcuts;
• Robust variables editor and variables preview;
• Optional variables sanitizing;
• Open with CLI.

...and a lot more...

StrongDMM is a single executable, which doesn't require any installation. You can download it by any of the provided link and start it right away.

Download Links:

• Windows
• Linux
• macOS

Release page contains all distributed files. It also has sha256 hashes info for every executable for validation purposes.

StrongDMM do support CLI to quickly open maps. Provide .dme or .dmm files as program arguments:

strongdmm.exe path/to/environment.dme ./map1.dmm ../path/map2.dmm

strongdmm.exe ./map1.dmm ../path/map2.dmm

When providing .dmm files without .dme, a proper environment file will be found automatically.

StrongDMM developed without any monetization in mind. The main motivation is an enthusiasm to do a cool stuff.
Your support can show your gratefulness and will motivate the project further development.

Also, if you want something specific to be implemented in the editor, it's possible to focus on your needs.

Q. My antivirus software detects something suspicious in the editor binaries. Is it ok?
A. Yes. It's a false positive reaction to the way how Golang (development language) creates binaries. Read more: https://go.dev/doc/faq#virus

Q. How do I verify my executables?
A. With sha256 hashes available on the release page.

Q. But how can I trust executables on the release page?
A. Executables are built with the CI pipeline. You can verify the process by yourself or build executables manually from the source code.

Q. How to uninstall the editor?
A. StrongDMM doesn't have any installation. Thus, no specific "uninstall" required as well. Delete the executable and, if you want to remove editor data, its directory on OS.

Q. Where do I find editor data?
A. For Windows: C:\Users\USER\AppData\Roaming\StrongDMM, for Linux/macOS: ~/.strongdmm.

Q. How to move the map?
A. Use zoom-in/zoom-out. Drag the pan with the middle mouse button. Or by holding a space key. Alternatively you can use arrow keys.

Q. How to zoom?
A. Scroll your mouse or use /- keys on the keyboard.

Q. How to change a save format?
A. In the menu bar: File->Preferences... and change to the format you need.

Q. The editor crushed. Where I can find logs?
A. Menu button: Help->Open Logs Folder.

There are two steps to build the application:

1. Build sdmmparser library;
2. Build the editor.

sdmmparser is a rust library based on SpacemanDMM parser. It is compiled to a staticlib. You can find it by path: src/third_party/sdmmparser/src.

• Go: version 1.19 or higher
• Rust: version 1.56.0 or higher
• (Optional) Task: to run build scripts

Ensure your Rust configured to use stable-x86_64-pc-windows-gnu toolchain. That requirement is based on the thing, that Go can't use MSVC to do builds. Thus, it won't link with libraries built using anything but GNU.

The easiest way to get GNU compiler is to install MinGW. This could be done with many ways: chocolatey package, msys2 etc.

You would probably need to add dependencies to build GUI apps: sudo apt install xorg-dev libgtk-3-dev.

Task is a cross-platform alternative for Make. Its scripts are described in the Taskfile.yml.

With installed Task you can basically do:

• task build: to build sdmmparser the editor (result will be in the dst dir)
• task run: to run the editor (will do a compilation under the hood)

1. The important part is to build sdmmparser library.
   Go to the src/third_party/sdmmparser/src directory and run the command: cargo build --release.
   If you don't modify sdmmparser you can do that step only once.
2. In the src dir you can do:
   • go build .: to build the editor (executable will be in the src dir with the name sdmm.exe/sdmm)
   • go run .: to run the editor

StrongDMM uses SpacemanDMM parser made by SpaceManiac.
The application icon is designed by Clément "Topy".
