Language Forge Documentation
A short guide on creating your own programming language and working in the workshop.
How to create your own language
- Choose a clear name and describe the problem the language should solve.
- Write the requirements: users, key constructs, limitations, and a real example.
- Choose a language style for the task: declarative, general-purpose, functional, or for devices.
- Click "Generate language plan" and study the blueprint with the next step.
- Refine the idea with the AI Engineer: ask about syntax, types, compiler stages, and contradictions.
How to use the workshop
- Edit the example in the language.lf editor.
- Click "Check code" to get tokens, AST, and diagnostics.
- Fix errors, then click "Run" to test the script.
- Use "Format" to clean up the example and "Copy" to move it to another tool.
- The draft is saved automatically, so you can return to the project later.
