🍑 Plum Language

🔆 Syntax highlighting and language support for the Plum programming language in VS Code.

Features

• Syntax highlighting for .plum files — keywords, strings, numbers, operators, comments, constants, types, and functions
• Language configuration — auto-closing brackets/quotes, comment toggling (--), bracket matching, auto-indentation for blocks
• Custom file icons for .plum files, available as two icon theme options:
  • Plum Icons — based on the built-in Seti theme, with a custom Plum icon added
  • Plum Icons (Material) — based on Material Icon Theme, with a custom Plum icon added
• Run command — Plum: Run File (plum.runFile) placeholder command, ready to be wired up to a Plum interpreter

Getting started

1. Install the extension
2. Open any .plum file — syntax highlighting applies automatically
3. On first activation, you'll be prompted to enable a Plum file icon theme (Seti-based or Material-based). You can also set it manually anytime via Preferences: File Icon Theme

Example

-- Plum example
root int MAX = 100

branch int add(int a, int b) {
    return a + b
}

branch void greet(str name) {
    drop "Hello, " + name
}

plant int result = add(5, 3)
drop result

if result > 10 {
    greet("world")
} else {
    greet("plum")
}
