3742 * File searching functions for 'path', 'tags' and 'cdpath' options. | |
3743 * External visible functions: | |
3744 * vim_findfile_init() creates/initialises the search context | |
3745 * vim_findfile_free_visited() free list of visited files/dirs of search | |
3746 * context | |
3747 * vim_findfile() find a file in the search context | |
3748 * vim_findfile_cleanup() cleanup/free search context created by | |
3749 * vim_findfile_init() | |
3750 * | |
3751 * All static functions and variables start with 'ff_' | |
3752 * | |
3753 * In general it works like this: | |
3754 * First you create yourself a search context by calling vim_findfile_init(). | |
3755 * It is possible to give a search context from a previous call to | |
3756 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |
3757 * until you are satisfied with the result or it returns NULL. On every call it | |
3758 * returns the next file which matches the conditions given to | |
3759 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
3760 * | |
3761 * It is possible to call vim_findfile_init() again to reinitialise your search | |
3762 * with some new parameters. Don't forget to pass your old search context to | |
3763 * it, so it can reuse it and especially reuse the list of already visited | |
3764 * directories. If you want to delete the list of already visited directories | |
3765 * simply call vim_findfile_free_visited(). | |
3766 * | |
3767 * When you are done call vim_findfile_cleanup() to free the search context. | |
3768 * | |
3769 * The function vim_findfile_init() has a long comment, which describes the | |
3770 * needed parameters. | |
3771 * | |
3772 * | |
3773 * | |
3774 * ATTENTION: | |
3775 * ========== | |
1072 | 3776 * Also we use an allocated search context here, this functions are NOT |
7 | 3777 * thread-safe!!!!! |
3778 * | |
3779 * To minimize parameter passing (or because I'm to lazy), only the | |
3780 * external visible functions get a search context as a parameter. This is | |
3781 * then assigned to a static global, which is used throughout the local | |
3782 * functions. | |

3982 * Returns the newly allocated search context or NULL if an error occurred. |
7 | 3983 * |
3984 * Don't forget to clean up by calling vim_findfile_cleanup() if you are done | |
3985 * with the search context. | |
3986 * | |
3987 * Find the file 'filename' in the directory 'path'. | |
3988 * The parameter 'path' may contain wildcards. If so only search 'level' | |
3989 * directories deep. The parameter 'level' is the absolute maximum and is | |
3990 * not related to restricts given to the '**' wildcard. If 'level' is 100 | |
3991 * and you use '**200' vim_findfile() will stop after 100 levels. | |
3992 * | |
1541 | 3993 * 'filename' cannot contain wildcards! It is used as-is, no backslashes to |
3994 * escape special characters. | |
3995 * | |
7 | 3996 * If 'stopdirs' is not NULL and nothing is found downward, the search is |
3997 * restarted on the next higher directory level. This is repeated until the | |
3998 * start-directory of a search is contained in 'stopdirs'. 'stopdirs' has the | |
3999 * format ";*<dirname>*\(;<dirname>\)*;\=$". | |
4000 * | |
4001 * If the 'path' is relative, the starting dir for the search is either VIM's | |
4002 * current dir or if the path starts with "./" the current files dir. | |

4003 * If the 'path' is absolute, the starting dir is that part of the path before |
7 | 4004 * the first wildcard. |
4005 * | |
4006 * Upward search is only done on the starting dir. | |
4007 * | |
4008 * If 'free_visited' is TRUE the list of already visited files/directories is | |
4009 * cleared. Set this to FALSE if you just want to search from another | |
4010 * directory, but want to be sure that no directory from a previous search is | |
4011 * searched again. This is useful if you search for a file at different places. | |
4012 * The list of visited files/dirs can also be cleared with the function | |
4013 * vim_findfile_free_visited(). | |
4014 * | |
1541 | 4015 * Set the parameter 'find_what' to FINDFILE_DIR if you want to search for |
4016 * directories only, FINDFILE_FILE for files only, FINDFILE_BOTH for both. | |
7 | 4017 * |
4018 * A search context returned by a previous call to vim_findfile_init() can be | |
1541 | 4019 * passed in the parameter "search_ctx_arg". This context is reused and |
4020 * reinitialized with the new parameters. The list of already visited | |
7 | 4021 * directories from this context is only deleted if the parameter |
1541 | 4022 * "free_visited" is true. Be aware that the passed "search_ctx_arg" is freed |
4023 * if the reinitialization fails. | |
7 | 4024 * |
1541 | 4025 * If you don't have a search context from a previous call "search_ctx_arg" |
4026 * must be NULL. | |
7 | 4027 * |
4028 * This function silently ignores a few errors, vim_findfile() will have | |
4029 * limited functionality then. | |
