Modules in Racket and How Code Gets Organized and Loaded
- Modules in Racket allow for organizing code into reusable, isolated units to prevent naming conflicts and enhance program manageability.
- Defining a module in Racket involves using the module form with specific structures and using provide to export functions.
- Dependencies are managed using require to load modules, making their functions available in the current namespace.
- Aliases can be used to simplify module imports and make code cleaner and more manageable.
- Racket modules can include macros that extend the language by defining reusable code patterns.
- The process of loading, compiling, and executing modules in Racket involves searching, verifying, compiling, and caching modules.
- Racket handles circular dependencies by using delayed loading to prevent infinite recursion.
- Submodules in Racket allow for grouping related functionality without exposing it to the main module.
- During execution, Racket evaluates top-level forms in modules in a specific order to ensure all dependencies are resolved.
- Understanding how Racket processes modules helps in maintaining code consistency and avoiding errors in program execution.
