Module namespace 

Parser for R package NAMESPACE files.

NAMESPACE files use a simple directive-based DSL with function-call syntax. Each directive is one of:

• export(name1, name2, ...) — export symbols
• exportPattern("^[^.]") — export symbols matching a regex
• import(pkg1, pkg2, ...) — import all exports from packages
• importFrom(pkg, sym1, sym2, ...) — import specific symbols from a package
• S3method(generic, class) or S3method(generic, class, method) — register S3 methods
• useDynLib(pkg, ...) — load a shared library
• exportClasses(cls1, cls2, ...) — export S4 classes
• exportMethods(meth1, meth2, ...) — export S4 methods
• importClassesFrom(pkg, cls1, cls2, ...) — import S4 classes from a package
• importMethodsFrom(pkg, meth1, meth2, ...) — import S4 methods from a package

Lines starting with # are comments. Directives can span multiple lines (the parser collects text until balanced parentheses).

Structs

DynLibDirective

A useDynLib directive.

Functions

collect_directives 🔒

Collect complete directives from a NAMESPACE file.

find_directive_after_if 🔒
