7.10 Single-Unit Modules🔗ℹ
When racket/unit is used as a language name with#lang, the module body is treated as a unit body. The body must match the following module-body grammar:
| module-body | = | require-decl ...(import tagged-sig-expr ...)(export tagged-sig-expr ...)init-depends-declunit-body-expr-or-defn... | ||
|---|---|---|---|---|
| require-decl | = | (require require-spec ...) | ||
| | | (begin require-decl ...) | |||
| | | derived-require-form |
After any number of require-decls, the content of the module is the same as a unit body.
The resulting unit is exported as base@, where base is derived from the enclosing module’s name (i.e., its symbolic name, or its path without the directory and file suffix). If the module name ends in -unit, thenbase corresponds to the module name before-unit. Otherwise, the module name serves asbase.
