Module `dmd.attrib`

Defines declarations of various attributes.

The term 'attribute' refers to things that can apply to a larger scope than a single declaration. Among them are: - Alignment (align(8)) - User defined attributes (@UDA) - Function Attributes (@safe) - Storage classes (static, __gshared) - Mixin declarations (mixin("int x;")) - Conditional compilation (static if, static foreach) - Linkage (extern(C)) - Anonymous structs / unions - Protection (private, public) - Deprecated declarations (@deprecated)

Functions

Name	Description
`foreachUda(sym, sc, dg)`	Iterates the UDAs attached to the given symbol.
`foreachUdaNoSemantic(sym, dg)`	Iterates the UDAs attached to the given symbol, without performing semantic analysis.
`isCoreUda(sym, ident)`	Returns `true` if the given symbol is a symbol declared in `core.attribute` and has the given identifier.

Classes

Name	Description
`AlignDeclaration`	Alignment attribute for aggregates, members and variables.
`AnonDeclaration`	An anonymous struct/union (defined by `isunion`).
`AttribDeclaration`	Abstract attribute applied to Dsymbol's used as a common ancestor for storage classes (StorageClassDeclaration), linkage (LinkageDeclaration) and others.
`CompileDeclaration`	Mixin declarations, like: mixin("int x");
`ConditionalDeclaration`	A conditional compilation declaration, used for `version` / `debug` and specialized for `static if`.
`CPPMangleDeclaration`	Attribute declaring whether an external aggregate should be mangled as a struct or class in C++, e.g. `extern(C++, struct) class C { ... }`. This is required for correct name mangling on MSVC targets, see cppmanglewin.d for details.
`CPPNamespaceDeclaration`	A node to represent an `extern(C++)` namespace attribute
`DeprecatedDeclaration`	Deprecation with an additional message applied to Dsymbols, e.g. `deprecated("Superseeded by foo") int bar;`. (Note that `deprecated int bar;` is currently represented as a StorageClassDeclaration with STC.deprecated_)
`ForwardingAttribDeclaration`	Collection of declarations that stores foreach index variables in a local symbol table. Other symbols declared within are forwarded to another scope, like:
`LinkDeclaration`	Linkage attribute applied to Dsymbols, e.g. `extern(C) void foo()`.
`PragmaDeclaration`	Pragma applied to Dsymbols, e.g. `pragma(inline, true) void foo`, but not PragmaStatement's like `pragma(msg, "hello");`.
`StaticForeachDeclaration`	Static foreach at declaration scope, like: static foreach (i; [0, 1, 2]){ }
`StaticIfDeclaration`	` { static if () { } else { } }`
`StorageClassDeclaration`	Storage classes applied to Dsymbols, e.g. `const int i;`
`UserAttributeDeclaration`	User defined attributes look like: @foo(args, ...) @(args, ...)
`VisibilityDeclaration`	Visibility declaration for Dsymbols, e.g. `public int i;`
