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_COLLECT_IGNORED`:::
38 Special mode for git-add. Return ignored files in `ignored[]` and
39 untracked files in `entries[]`. Only returns ignored files that match
40 pathspec exactly (no wildcards). Does not recurse into ignored
43 `DIR_SHOW_OTHER_DIRECTORIES`:::
45 Include a directory that is not tracked.
47 `DIR_HIDE_EMPTY_DIRECTORIES`:::
49 Do not include a directory that is not tracked and is empty.
53 If set, recurse into a directory that looks like a Git
54 directory. Otherwise it is shown as a directory.
56 The result of the enumeration is left in these fields:
60 An array of `struct dir_entry`, each element of which describes
65 The number of members in `entries[]` array.
69 Internal use; keeps track of allocation of `entries[]` array.
73 An array of `struct dir_entry`, used for ignored paths with the
74 `DIR_SHOW_IGNORED_TOO` and `DIR_COLLECT_IGNORED` flags.
78 The number of members in `ignored[]` array.
83 Note: index may be looked at for .gitignore files that are CE_SKIP_WORKTREE
84 marked. If you to exclude files, make sure you have loaded index first.
86 * Prepare `struct dir_struct dir` and clear it with `memset(&dir, 0,
89 * To add single exclude pattern, call `add_exclude_list()` and then
92 * To add patterns from a file (e.g. `.git/info/exclude`), call
93 `add_excludes_from_file()` , and/or set `dir.exclude_per_dir`. A
94 short-hand function `setup_standard_excludes()` can be used to set
95 up the standard set of exclude settings.
97 * Set options described in the Data Structure section above.
99 * Call `read_directory()`.
101 * Use `dir.entries[]`.
103 * Call `clear_directory()` when none of the contained elements are no longer in use.
