我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用ply.lex.lineno()。
def t_CPP_STRING(t): r'\"([^\\\n]|(\\(.|\n)))*?\"' t.lexer.lineno += t.value.count("\n") return t # Character constant 'c' or L'c'
def group_lines(self,input): lex = self.lexer.clone() lines = [x.rstrip() for x in input.splitlines()] for i in xrange(len(lines)): j = i+1 while lines[i].endswith('\\') and (j < len(lines)): lines[i] = lines[i][:-1]+lines[j] lines[j] = "" j += 1 input = "\n".join(lines) lex.input(input) lex.lineno = 1 current_line = [] while True: tok = lex.token() if not tok: break current_line.append(tok) if tok.type in self.t_WS and '\n' in tok.value: yield current_line current_line = [] if current_line: yield current_line # ---------------------------------------------------------------------- # tokenstrip() # # Remove leading/trailing whitespace tokens from a token list # ----------------------------------------------------------------------
def t_CPP_WS(t): r'\s+' t.lexer.lineno += t.value.count("\n") return t
def t_CPP_CHAR(t): r'(L)?\'([^\\\n]|(\\(.|\n)))*?\'' t.lexer.lineno += t.value.count("\n") return t # Comment
def t_CPP_COMMENT(t): r'(/\*(.|\n)*?\*/)|(//.*?\n)' t.lexer.lineno += t.value.count("\n") return t
def t_CPP_COMMENT1(t): r'(/\*(.|\n)*?\*/)' ncr = t.value.count("\n") t.lexer.lineno += ncr # replace with one space or a number of '\n' t.type = 'CPP_WS'; t.value = '\n' * ncr if ncr else ' ' return t # Line comment
def group_lines(self,input): lex = self.lexer.clone() lines = [x.rstrip() for x in input.splitlines()] for i in range(len(lines)): j = i+1 while lines[i].endswith('\\') and (j < len(lines)): lines[i] = lines[i][:-1]+lines[j] lines[j] = "" j += 1 input = "\n".join(lines) lex.input(input) lex.lineno = 1 current_line = [] while True: tok = lex.token() if not tok: break current_line.append(tok) if tok.type in self.t_WS and '\n' in tok.value: yield current_line current_line = [] if current_line: yield current_line # ---------------------------------------------------------------------- # tokenstrip() # # Remove leading/trailing whitespace tokens from a token list # ----------------------------------------------------------------------
