Clang can parse more complicated source files like Boost libraries. 45 | 46 | Screenshot: 47 | 48 | ![screenshot](http://gifzo.net/82IlUtfW1g.gif) 49 | 50 | ## More complicated operator-pending mappings 51 | 52 | If you set `g:textobj_clang_more_mappings` to `1`, many operator-pending mappings are defined. As a default, mappings in a below table are defined. You can control the number of the mappings with `g:textobj_clang_mapping_kinds`. 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 |
