This is in contrast to '(' and ')', which must be balanced. 16 * 17 * TODO: try to split this token into lsym_rbrace_block and lsym_rbrace_init. 18 * 19 * See also: 20 * lsym_lbrace.c 21 */ 22 23/* Brace level in an initializer */ 24//indent input 25void 26function(void) 27{ 28 struct person p = { 29 .name = "Name", 30 .age = {{{35}}}, /* C11 6.7.9 allows this. */ 31 }; 32} 33//indent end 34 35//indent run-equals-input 36 37 38/* Begin of a block of statements */ 39//indent input 40void function(void) {{{ body(); }}} 41//indent end 42 43//indent run 44void 45function(void) 46{ 47 { 48 { 49 body(); 50 } 51 } 52} 53//indent end 54 55 56/* Compound literal */ 57//indent input 58struct point 59origin(void) 60{ 61 return (struct point){ 62 .x = 0, 63 .y = 0, 64 }; 65} 66//indent end 67 68//indent run-equals-input 69 70 71//indent input 72{ 73int numbers[][] = { 74{11}, 75{21}, 76{31}, 77}; 78int numbers[][] = {{11}, 79{21}, 80{31}, 81}; 82} 83//indent end 84 85//indent run -di0 86{ 87 int numbers[][] = { 88 {11}, 89 {21}, 90 {31}, 91 }; 92 int numbers[][] = {{11}, 93 // $ FIXME: Must be indented. 94 {21}, 95 {31}, 96 }; 97} 98//indent end 99
