1 # File collection and discovery
2
3 You can directly pass _Black_ files, but you can also pass directories and _Black_ will
4 walk them, collecting files to format. It determines what files to format or skip
5 automatically using the inclusion and exclusion regexes and as well their modification
6 time.
7
8 ## Ignoring unmodified files
9
10 _Black_ remembers files it has already formatted, unless the `--diff` flag is used or
11 code is passed via standard input. This information is stored per-user. The exact
12 location of the file depends on the _Black_ version and the system on which _Black_ is
13 run. The file is non-portable. The standard location on common operating systems is:
14
15 - Windows:
16   `C:\\Users\<username>\AppData\Local\black\black\Cache\<version>\cache.<line-length>.<file-mode>.pickle`
17 - macOS:
18   `/Users/<username>/Library/Caches/black/<version>/cache.<line-length>.<file-mode>.pickle`
19 - Linux:
20   `/home/<username>/.cache/black/<version>/cache.<line-length>.<file-mode>.pickle`
21
22 `file-mode` is an int flag that determines whether the file was formatted as 3.6+ only,
23 as .pyi, and whether string normalization was omitted.
24
25 To override the location of these files on all systems, set the environment variable
26 `BLACK_CACHE_DIR` to the preferred location. Alternatively on macOS and Linux, set
27 `XDG_CACHE_HOME` to your preferred location. For example, if you want to put the cache
28 in the directory you're running _Black_ from, set `BLACK_CACHE_DIR=.cache/black`.
29 _Black_ will then write the above files to `.cache/black`. Note that `BLACK_CACHE_DIR`
30 will take precedence over `XDG_CACHE_HOME` if both are set.
31
32 ## .gitignore
33
34 If `--exclude` is not set, _Black_ will automatically ignore files and directories in
35 `.gitignore` file(s), if present.
36
37 If you want _Black_ to continue using `.gitignore` while also configuring the exclusion
38 rules, please use `--extend-exclude`.
