4 The directory listing API is used to enumerate paths in the work tree,
5 optionally taking `.git/info/exclude` and `.gitignore` files per
6 directory into account.
11 `struct dir_struct` structure is used to pass directory traversal
12 options to the library and to record the paths discovered. A single
13 `struct dir_struct` is used regardless of whether or not the traversal
14 recursively descends into subdirectories.
16 The notable options are:
20 The name of the file to be read in each directory for excluded
21 files (typically `.gitignore`).
25 A bit-field of options (the `*IGNORED*` flags are mutually exclusive):
29 Return just ignored files in `entries[]`, not untracked files.
31 `DIR_SHOW_IGNORED_TOO`:::
33 Similar to `DIR_SHOW_IGNORED`, but return ignored files in `ignored[]`
34 in addition to untracked files in `entries[]`.
36 `DIR_KEEP_UNTRACKED_CONTENTS`:::
38 Only has meaning if `DIR_SHOW_IGNORED_TOO` is also set; if this is set, the
39 untracked contents of untracked directories are also returned in
42 `DIR_COLLECT_IGNORED`:::
44 Special mode for git-add. Return ignored files in `ignored[]` and
45 untracked files in `entries[]`. Only returns ignored files that match
46 pathspec exactly (no wildcards). Does not recurse into ignored
49 `DIR_SHOW_OTHER_DIRECTORIES`:::
51 Include a directory that is not tracked.
53 `DIR_HIDE_EMPTY_DIRECTORIES`:::
55 Do not include a directory that is not tracked and is empty.
59 If set, recurse into a directory that looks like a Git
60 directory. Otherwise it is shown as a directory.
62 The result of the enumeration is left in these fields:
66 An array of `struct dir_entry`, each element of which describes
71 The number of members in `entries[]` array.
75 Internal use; keeps track of allocation of `entries[]` array.
79 An array of `struct dir_entry`, used for ignored paths with the
80 `DIR_SHOW_IGNORED_TOO` and `DIR_COLLECT_IGNORED` flags.
84 The number of members in `ignored[]` array.
89 Note: index may be looked at for .gitignore files that are CE_SKIP_WORKTREE
90 marked. If you to exclude files, make sure you have loaded index first.
92 * Prepare `struct dir_struct dir` and clear it with `memset(&dir, 0,
95 * To add single exclude pattern, call `add_exclude_list()` and then
98 * To add patterns from a file (e.g. `.git/info/exclude`), call
99 `add_excludes_from_file()` , and/or set `dir.exclude_per_dir`. A
100 short-hand function `setup_standard_excludes()` can be used to set
101 up the standard set of exclude settings.
103 * Set options described in the Data Structure section above.
105 * Call `read_directory()`.
107 * Use `dir.entries[]`.
109 * Call `clear_directory()` when none of the contained elements are no longer in use.
