The grammer is specified by supplying the BNF inside # Python documentation strings. The inspiration for this technique was borrowed # from John Aycock's Spark parsing system. PLY might be viewed as cross between # Spark and the GNU bison utility. # # The current implementation is only somewhat object-oriented. The # LR parser itself is defined in terms of an object (which allows multiple # parsers to co-exist). However, most of the variables used during table # construction are defined in terms of global variables. Users shouldn't # notice unless they are trying to define multiple parsers at the same # time using threads (in which case they should have their head examined). # # This implementation supports both SLR and LALR(1) parsing. LALR(1) # support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu), # using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles, # Techniques, and Tools" (The Dragon Book). LALR(1) has since been replaced # by the more efficient DeRemer and Pennello algorithm. # # :::::::: WARNING ::::::: # # Construction of LR parsing tables is fairly complicated and expensive. # To make this module run fast, a *LOT* of work has been put into # optimization---often at the expensive of readability and what might # consider to be good Python "coding style."

Additionally, consecutive (fall-through) case statements come out messy. This is a peculiarity of the C grammar. The following: switch (myvar) { case 10: k = 10; p = k + 1; return 10; case 20: case 30: return 20; default: break; } Creates this tree (pseudo-dump): Switch ID: myvar Compound: Case 10: k = 10 p = k + 1 return 10 Case 20: Case 30: return 20 Default: break The goal of this transform is to fix this mess, turning it into the following: Switch ID: myvar Compound: Case 10: k = 10 p = k + 1 return 10 Case 20: Case 30: return 20 Default: break A fixed AST node is returned.

Some arguments for controlling the debug/optimization level of the parser are provided. The defaults are tuned for release/performance mode. The simple rules for using them are: *) When tweaking CParser/CLexer, set these to False *) When releasing a stable parser, set to True lex_optimize: Set to False when you're modifying the lexer. Otherwise, changes in the lexer won't be used, if some lextab.py file exists. When releasing with a stable lexer, set to True to save the re-generation of the lexer table on each run. lexer: Set this parameter to define the lexer to use if you're not using the default CLexer. lextab: Points to the lex table that's used for optimized mode. Only if you're modifying the lexer and want some tests to avoid re-generating the table, make this point to a local lex table file (that's been earlier generated with lex_optimize=True) yacc_optimize: Set to False when you're modifying the parser. Otherwise, changes in the parser won't be used, if some parsetab.py file exists. When releasing with a stable parser, set to True to save the re-generation of the parser table on each run. yacctab: Points to the yacc table that's used for optimized mode. Only if you're modifying the parser, make this point to a local yacc table file yacc_debug: Generate a parser.out file that explains how yacc built the parsing table from the grammar. taboutputdir: Set this parameter to control the location of generated lextab and yacctab files. )� error_func�on_lbrace_func�on_rbrace_func�type_lookup_func)�optimize�lextab� outputdir)�abstract_declarator�assignment_expression�declaration_list� declaration_specifiers_no_type� designation� expression�identifier_list�init_declarator_list�id_init_declarator_list�initializer_list�parameter_type_list�block_item_list�type_qualifier_list�struct_declarator_list�translation_unit_or_empty)�module�start�debugr � tabmoduler N) �_lex_error_func�_lex_on_lbrace_func�_lex_on_rbrace_func�_lex_type_lookup_func�clex�build�tokens�_create_opt_ruler �cparser�dict� _scope_stack�_last_yielded_token) �self� lex_optimize�lexerr � yacc_optimize�yacctab� yacc_debug� taboutputdir�rules_with_opt�rule� r< �H/usr/local/CyberPanel/lib/python3.10/site-packages/pycparser/c_parser.py�__init__ s2 :�� � zCParser.__init__c C s6 || j _| j �� t� g| _d| _| jj|| j |d�S )a Parses C code and returns an AST. text: A string containing the C source code filename: Name of the file being parsed (for meaningful error messages) debug: Debug flag to YACC N)�inputr5 r% )r+ �filename� reset_linenor0 r1 r2 r/ �parse)r3 �textr@ r% r< r< r= rB � s �z CParser.parsec C s | j �t� � d S �N)r1 �appendr0 �r3 r< r< r= � _push_scope� s zCParser._push_scopec C s t | j�dks J �| j�� d S )Nr )�lenr1 �poprF r< r< r= � _pop_scope� s zCParser._pop_scopec C s4 | j d �|d�s| �d| |� d| j d |< dS )zC Add a new typedef name (ie a TYPEID) to the current scope ���Tz;Typedef %r previously declared as non-typedef in this scopeN�r1 �get� _parse_error�r3 �name�coordr< r< r= �_add_typedef_name� s ��zCParser._add_typedef_namec C s4 | j d �|d�r| �d| |� d| j d |< dS )ze Add a new object, function, or enum member name (ie an ID) to the current scope rK Fz;Non-typedef %r previously declared as typedef in this scopeNrL rO r< r< r= �_add_identifier� s ��zCParser._add_identifierc C s. t | j�D ]}|�|�}|dur| S qdS )z8 Is *name* a typedef-name in the current scope?

Subclass it and define your own visit_XXX methods, where XXX is the class name you want to visit with these methods. For example: class ConstantVisitor(NodeVisitor): def __init__(self): self.values = [] def visit_Constant(self, node): self.values.append(node.value) Creates a list of values of all the constant nodes encountered below the given node. To use it: cv = ConstantVisitor() cv.visit(node) Notes: * generic_visit() will be called for AST nodes for which no visit_XXX method was defined. * The children of nodes for which a visit_XXX was defined will not be visited - if you need this, call generic_visit() on the node. You can use: NodeVisitor.generic_visit(self, node) * Modeled after Python's own AST visiting facilities (the ast module of Python 3.0) Nc C sZ | j du ri | _ | j �|jjd�}|du r)d|jj }t| || j�}|| j |jj< ||�S )z Visit a node.
