Build a Language

This section groups the main subsystem guides for designing and wiring a language with Pegium.

If you want the guided end-to-end path, start with Pegium's Workflow. If you already know the common workflow and want focused reading on one subsystem at a time, use the pages below.

Topics

• Grammar essentials
• AST and CST
• References and scoping
• Validation
• Formatting
• LSP services
• Workspace lifecycle

Where to go from here?

• Use Learn for the recommended order of implementation.
• Use these pages when you want a topic-by-topic explanation of one subsystem.
• Use Reference when you need the exact framework concepts behind a subsystem.
