1 /* vi:set ts=8 sts=4 sw=4 noet: |
| 7 | 2 * |
| 3 * CSCOPE support for Vim added by Andy Kahn <kahn@zk3.dec.com> | |
| 148 | 4 * Ported to Win32 by Sergey Khorev <sergey.khorev@gmail.com> |
| 7 | 5 * |
| 6 * The basic idea/structure of cscope for Vim was borrowed from Nvi. There | |
| 7 * might be a few lines of code that look similar to what Nvi has. | |
| 8 * | |
| 9 * See README.txt for an overview of the Vim source code. | |

1597 * Convert the cscope output into a ctags style entry (as might be found |
| 7 | 1598 * in a ctags tags file). there's one catch though: cscope doesn't tell you |
| 1599 * the type of the tag you are looking for. for example, in Darren Hiebert's | |
| 1600 * ctags (the one that comes with vim), #define's use a line number to find the | |
| 1601 * tag in a file while function definitions use a regexp search pattern. | |

1603 * I'm going to always use the line number because cscope does something |

| 1606 * if you have "# define" in your source file, which is | |
