Matrix-first, by design
Vectors and matrices belong in the language, not behind layers of setup. Write matrix literals and work with familiar 1-based indexing.

01 / THE SUNNYLABS VISION
Good tools make room
for better questions.
Scientific programming should let you focus on the problem in front of you. Not the ceremony around it.
We are bringing a mathematically expressive language and a focused development environment together. One connected workflow for students, engineers, researchers, and curious developers.

5Interpreted with SunMath you can read
Multiply matrices, apply element-wise operations, transpose, find determinants, and solve linear systems with concise expressions.
Powerful control flow
Build more expressive programs with conditionals, loops, switch statements, and structured error handling using try/catch.
These examples use the interpreter. Native compilation supports a smaller, evolving subset.

A Monaco-based editor and project explorer, built with Electron, React, and TypeScript.
Connected to the language
Run and check Sun programs through the CLI-backed engine. Keep code and feedback close together.
A scientific workspace
Inspect variables and matrix values as you work. Scientific exploration remains an active area of development.
A work in progress, by design. Sun Editor is in active development. The screenshot above shows the Sun Studio desktop application. Its interface and capabilities may change as development progresses.

A LITTLE MORE CONTEXTGood questions.
Good questions.
Honest answers.
Early days, clear intentions.
What can I use Sun for today?
Sun is an experimental environment for matrix calculations, numerical experiments, and learning computational mathematics. Its interpreter supports matrix operations, linear algebra, and control flow. Capabilities continue to evolve as the language develops.
Can Sun handle complex programs?
Yes. Sun supports conditional logic, for and while loops, switch statements, functions, and try/catch error handling alongside its numerical and matrix operations. Native compilation currently supports a smaller subset than the interpreter.
Do I need Sun Editor to use the language?
No. The Sun CLI can run and check source files and launch a REPL on its own. Sun Editor is the companion desktop workspace, integrating editing, execution feedback, and workspace inspection with the Sun engine.
Is the native compiler feature-complete?
Not yet. The LLVM/Clang compilation path supports a subset of the language, including selected scalar and dense-matrix operations. The interpreter supports more operations. Native compilation capabilities are evolving alongside the interpreter.
