Ignoring unmodified files¶
Black remembers files it has already formatted, unless the --diff
flag is used or
code is passed via standard input. This information is stored per-user. The exact
location of the file depends on the Black version and the system on which Black
is run. The file is non-portable. The standard location on common operating systems
is:
- Windows:
C:\\Users\<username>\AppData\Local\black\black\Cache\<version>\cache.<line-length>.<file-mode>.pickle
- macOS:
/Users/<username>/Library/Caches/black/<version>/cache.<line-length>.<file-mode>.pickle
- Linux:
/home/<username>/.cache/black/<version>/cache.<line-length>.<file-mode>.pickle
file-mode
is an int flag that determines whether the file was formatted as 3.6+ only,
as .pyi, and whether string normalization was omitted.
