Showcases

Pegium ships several end-to-end examples. Each one is both a showcase of the framework and a starting point for real projects.

Arithmetics

The arithmetics example is the smallest complete showcase. It includes:

  • a grammar with precedence-aware expressions
  • an evaluator
  • validation and formatting
  • a language server and VS Code client

DomainModel

The domainmodel example shows a modeling DSL with:

  • nested declarations
  • qualified names
  • rename support
  • formatter rules for block-oriented syntax

Requirements

The requirements example demonstrates:

  • multiple related languages
  • shared workspace behavior
  • cross-file and cross-language references
  • one LSP server serving more than one language id

Statemachine

The statemachine example focuses on:

  • semantic validation
  • state-oriented modeling
  • formatting and editor integration

Practical advice

Want to inspect just one showcase before learning Pegium? Start with arithmetics. It's the most compact example that still exercises the full parser-to-editor path.
