_c_ast.cfg
#----------------------------------------------------------------- # pycparser: _c_ast.cfg # # Defines the AST Node classes used in pycparser. # # Each entry is a Node sub-class name, listing the attributes # and child nodes of the class: # <name>* - a child node # <name>** - a sequence of child nodes # <name> - an attribute # # Eli Bendersky [https://eli.thegreenplace.net/] # License: BSD #----------------------------------------------------------------- # ArrayDecl is a nested declaration of an array with the given type. # dim: the dimension (for example, constant 42) # dim_quals: list of dimension qualifiers, to support C99's allowing 'const' # and 'static' within the array dimension in function declarations. ArrayDecl: [type*, dim*, dim_quals] ArrayRef: [name*, subscript*] # op: =, +=, /= etc. # Assignment: [op, lvalue*, rvalue*] BinaryOp: [op, left*, right*] Break: [] Case: [expr*, stmts**] Cast: [to_type*, expr*] # Compound statement in C99 is a list of block items (declarations or # statements). # Compound: [block_items**] # Compound literal (anonymous aggregate) for C99. # (type-name) {initializer_list} # type: the typename # init: InitList for the initializer list # CompoundLiteral: [type*, init*] # type: int, char, float, etc. see CLexer for constant token types # Constant: [type, value] Continue: [] # name: the variable being declared # quals: list of qualifiers (const, volatile) # funcspec: list function specifiers (i.e. inline in C99) # storage: list of storage specifiers (extern, register, etc.) # type: declaration type (probably nested with all the modifiers) # init: initialization value, or None # bitsize: bit field size, or None # Decl: [name, quals, storage, funcspec, type*, init*, bitsize*] DeclList: [decls**] Default: [stmts**] DoWhile: [cond*, stmt*] # Represents the ellipsis (...) parameter in a function # declaration # EllipsisParam: [] # An empty statement (a semicolon ';' on its own) # EmptyStatement: [] # Enumeration type specifier # name: an optional ID # values: an EnumeratorList # Enum: [name, values*] # A name/value pair for enumeration values # Enumerator: [name, value*] # A list of enumerators # EnumeratorList: [enumerators**] # A list of expressions separated by the comma operator. # ExprList: [exprs**] # This is the top of the AST, representing a single C file (a # translation unit in K&R jargon).
