| 3849 * File searching functions for 'path', 'tags' and 'cdpath' options. | |
| 3850 * External visible functions: | |
| 3851 * vim_findfile_init() creates/initialises the search context | |
| 3852 * vim_findfile_free_visited() free list of visited files/dirs of search | |
| 3853 * context | |
| 3854 * vim_findfile() find a file in the search context | |
| 3855 * vim_findfile_cleanup() cleanup/free search context created by | |
| 3856 * vim_findfile_init() | |
| 3857 * | |
| 3858 * All static functions and variables start with 'ff_' | |
| 3859 * | |
| 3860 * In general it works like this: | |
| 3861 * First you create yourself a search context by calling vim_findfile_init(). | |
| 3862 * It is possible to give a search context from a previous call to | |
| 3863 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
| 3864 * until you are satisfied with the result or it returns NULL. On every call it | |
| 3865 * returns the next file which matches the conditions given to | |
| 3866 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
| 3867 * | |
| 3868 * It is possible to call vim_findfile_init() again to reinitialise your search | |
| 3869 * with some new parameters. Don't forget to pass your old search context to | |
| 3870 * it, so it can reuse it and especially reuse the list of already visited | |
| 3871 * directories. If you want to delete the list of already visited directories | |
| 3872 * simply call vim_findfile_free_visited(). | |
| 3873 * | |
| 3874 * When you are done call vim_findfile_cleanup() to free the search context. | |
| 3875 * | |
| 3876 * The function vim_findfile_init() has a long comment, which describes the | |
| 3877 * needed parameters. | |

| 7 | 3884 * thread-safe!!!!! |
| 3885 * | |
| 3886 * To minimize parameter passing (or because I'm to lazy), only the | |
| 3887 * external visible functions get a search context as a parameter. This is | |
| 3888 * then assigned to a static global, which is used throughout the local | |

4089 * Returns the newly allocated search context or NULL if an error occurred. |
| 7 | 4090 * |
| 4091 * Don't forget to clean up by calling vim_findfile_cleanup() if you are done | |
| 4092 * with the search context. | |
| 4093 * | |
| 4094 * Find the file 'filename' in the directory 'path'. | |
| 4095 * The parameter 'path' may contain wildcards. If so only search 'level' | |
| 4096 * directories deep. The parameter 'level' is the absolute maximum and is | |
| 4097 * not related to restricts given to the '**' wildcard. If 'level' is 100 | |
| 4098 * and you use '**200' vim_findfile() will stop after 100 levels. | |
| 4099 * | |
| 1541 | 4100 * 'filename' cannot contain wildcards! It is used as-is, no backslashes to |
| 4101 * escape special characters. | |
| 4102 * | |
| 7 | 4103 * If 'stopdirs' is not NULL and nothing is found downward, the search is |
| 4104 * restarted on the next higher directory level. This is repeated until the | |
| 4105 * start-directory of a search is contained in 'stopdirs'. 'stopdirs' has the | |
| 4106 * format ";*<dirname>*\(;<dirname>\)*;\=$". | |
| 4107 * | |
| 4108 * If the 'path' is relative, the starting dir for the search is either VIM's | |
| 4109 * current dir or if the path starts with "./" the current files dir. | |

4110 * If the 'path' is absolute, the starting dir is that part of the path before |
| 7 | 4111 * the first wildcard. |
| 4112 * | |
| 4113 * Upward search is only done on the starting dir. | |
| 4114 * | |
| 4115 * If 'free_visited' is TRUE the list of already visited files/directories is | |
| 4116 * cleared. Set this to FALSE if you just want to search from another | |
| 4117 * directory, but want to be sure that no directory from a previous search is | |
| 4118 * searched again. This is useful if you search for a file at different places. | |
| 4119 * The list of visited files/dirs can also be cleared with the function | |
| 4120 * vim_findfile_free_visited(). | |
| 4121 * | |
| 1541 | 4122 * Set the parameter 'find_what' to FINDFILE_DIR if you want to search for |
| 4123 * directories only, FINDFILE_FILE for files only, FINDFILE_BOTH for both. | |
| 7 | 4124 * |
| 4125 * A search context returned by a previous call to vim_findfile_init() can be | |
| 1541 | 4126 * passed in the parameter "search_ctx_arg". This context is reused and |
| 4127 * reinitialized with the new parameters. The list of already visited | |
| 7 | 4128 * directories from this context is only deleted if the parameter |
| 1541 | 4129 * "free_visited" is true. Be aware that the passed "search_ctx_arg" is freed |
| 4130 * if the reinitialization fails. | |
| 7 | 4131 * |
| 1541 | 4132 * If you don't have a search context from a previous call "search_ctx_arg" |
| 4133 * must be NULL. | |
| 7 | 4134 * |
| 4135 * This function silently ignores a few errors, vim_findfile() will have | |
| 4136 * limited functionality then. | |
