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. )Z error_funcZon_lbrace_funcZon_rbrace_funcZtype_lookup_func)�optimize�lextab� outputdir)Zabstract_declaratorZassignment_expressionZdeclaration_listZ declaration_specifiers_no_typeZ designationZ expressionZidentifier_listZinit_declarator_listZid_init_declarator_listZinitializer_listZparameter_type_listZblock_item_listZtype_qualifier_listZstruct_declarator_listZtranslation_unit_or_empty)�module�start�debugr Z tabmoduler N) �_lex_error_func�_lex_on_lbrace_func�_lex_on_rbrace_func�_lex_type_lookup_func�clexZbuild�tokensZ_create_opt_ruler �cparser�dict� _scope_stack�_last_yielded_token) �selfZ lex_optimize�lexerr Z yacc_optimizeZyacctabZ yacc_debugZ taboutputdirZrules_with_optZrule� r �6/usr/lib/python3.9/site-packages/pycparser/c_parser.py�__init__ s2 :�� � zCParser.__init__r 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) debuglevel: Debug level to yacc N)�inputr r )r �filenameZ reset_linenor r r r �parse)r �textr$ Z debuglevelr r r! r% � s �z CParser.parsec C s | j �t� � d S �N)r �appendr �r r r r! � _push_scope� s zCParser._push_scopec C s t | j�dksJ �| j�� d S )Nr )�lenr �popr) 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�r �get� _parse_error�r �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 r.
