Mindcode & Schemacode

Welcome to Mindcode, a high-level language for Mindustry. Mindustry is a game in the tower-defense genre. Mindustry added Logic in late 2020. Logic is a programming language, closer to assembly than a high-level language. Mindcode aims to make Mindustry programming easier for everyone.

Mindcode focuses of the following priorities:

Keeping terminology and naming convention close to Mindustry Logic.
Providing language constructs that are not prohibitively expensive given the astonishingly slow speeds and limited instruction space of Mindustry processors.
Employing various optimizations to produce efficient code.

[!NOTE] Please have a look at a poll about introducing compulsory semicolons to the Mindcode syntax here.

Schemacode is a specialized definition language designed for creating a complete Mindustry schematic as a text file. Schematics builder can be used to turn these definition files directly into Mindustry schematics, either as a binary .msch file, or as a text. Processors can be included in these schematics, complete with the code (specified in Mindcode or Mindustry Logic language) and linked blocks.

Latest development

Some of the latest enhancements to Mindcode are:

Loop Hoisting, a new optimization designed to pull invariant code out of loops to avoid repeated execution where possible.
All instructions added in Mindustry 7 build 146 are now supported.

A changelog is now maintained for releases.

Using Mindcode

Mindcode is available at http://mindcode.herokuapp.com/. Write some Mindcode in the Mindcode Source Code text area, then press the Compile button. The Mindustry Logic text area will contain the Logic version of your Mindcode. Copy the compiled version. Back in Mindustry, edit your processor, then use the Edit button in the Logic UI. Select Import from Clipboard. Mindustry is now ready to execute your code.

It is also possible to build Mindcode locally (see the Development section), and use the command line tool to compile your files, even copying the compiled code into the clipboard automatically if desired.

Mindcode Syntax

Please read the syntax document for a complete description of Mindcode syntax. The samples in the src/main/resources/samples directory are compiled on every test run and are thus always up-to-date with the most-recent version of Mindcode. If you programmed in any high-level language, you should feel right at home.

VS Code syntax highlighting

@schittli kindly contributed a VS Code syntax highlighter.

Download the extension from the Visual Studio marketplace. I'm not sure how well the extension supports latest additions to Mindcode.

IntelliJ IDEA syntax highlighting

IntelliJ IDEA (even the Community edition) can be easily configured for basic Mindcode syntax highlighting.

Go to File / Settings, or press Ctrl-Alt-S
Navigate to Editor / File types

Mindustry Logic References

If you don't know much about Mindustry Logic, you can read more information about them here:

There also exists a VSCode syntax highlighter for Mindustry Logic.

Development

There are two options for getting Mindcode up and running on your own machine. Using Docker, or running it natively:

With Docker & Docker Compose

docker-compose up --build

It can take a few minutes to download and compile all the required parts the first time you run this, but subsequent runs will be a lot faster.

The Mindcode UI will now be running on localhost, port 8080. Visit http://localhost:8080/ to interact with it.

Native installation

Install Java 17+, Maven 3.6, and PostgreSQL
Create a database in PostgreSQL named mindcode_development

Note: Docker configuration has been updated to allow running Mindcode in Docker alongside a local PostgreSQL installation.

Windows

Set environment variables with the PostgreSQL connection parameters. You can set them by running the following commands in the console:

SET SPRING_DATASOURCE_URL=jdbc:postgresql://localhost/mindcode_development
SET SPRING_DATASOURCE_USERNAME=postgres_username
SET SPRING_DATASOURCE_PASSWORD=postgres_password

You also need to set a JAVA_HOME variable pointing to the directory containing your Java 17 installation, for example (the exact path depends on the distribution and version of Java you've installed):

SET JAVA_HOME=C:\Program Files\Eclipse Adoptium\jdk-17.0.6.10-hotspot

(You can also set all these variables permanently in the System Properties dialog, in the Advanced tab, after pressing the Environment Variables... button.)

Then, using the same console window, run:

mvnw.cmd install

to build the app, and then

bin\webapp.bat

The Mindcode UI will now be running on localhost, port 8080. Visit http://localhost:8080/ to interact with it.

Linux

Set environment variables with the PostgreSQL connection parameters:

export SPRING_DATASOURCE_URL=jdbc:postgresql://localhost/mindcode_development
export SPRING_DATASOURCE_USERNAME=postgres_username
export SPRING_DATASOURCE_PASSWORD=postgres_password

Then run:

./mvnw install

from the project root to build the app, and then

bin/run-local

The Mindcode UI will now be running on localhost, port 8080. Visit http://localhost:8080/ to interact with it.

IDE

To run the application for your IDE, set the environment variables as described above (some IDEs allow to set them just in the IDE) and set the startup class to info.teksol.mindcode.webapp.WebappApplication. When you run or debug the project, the Mindcode UI will now be running on localhost, port 8080. Visit http://localhost:8080/ to interact with it.

Contributing

The compiler was written in a Test-Driven Development fashion. If you can, please look in src/main/test and attempt to emulate an existing test, so that we can prove that your proposal works as intended.

Tests in the info.teksol.mindcode.processor package are particularly useful. They compile a script and run it on an emulated processor, comparing values produced by print instructions with expected ones. The processor emulator cannot execute instructions interfacing with the Mindustry world - except Memory Bank and MemoryCell - but it can process all kinds of Mindcode control elements. Implementing some more complicated algorithms using loops, conditional statements and/or function helps tremendously. (The emulated processor runs much faster than Mindcode processors, so even more complicated algorithms are feasible to run.)
