./pants fmt [args]

Autoformat source code.

Config section: [fmt]

Basic options

None

Advanced options

--[no-]fmt-per-file-caching
PANTS_FMT_PER_FILE_CACHING
per_file_caching
default: False
Rather than formatting all files in a single batch, format each file as a separate process. Why do this? You'll get many more cache hits. Why not do this? Formatters both have substantial startup overhead and are cheap to add one additional file to the run. On a cold cache, it is much faster to use `--no-per-file-caching`. We only recommend using `--per-file-caching` if you are using a remote cache or if you have benchmarked that this option will be faster than `--no-per-file-caching` for your use case.

Deprecated options

--[no-]fmt-per-target-caching
PANTS_FMT_PER_TARGET_CACHING
per_target_caching
default: False
Deprecated, will be removed in version: 2.1.0.dev0
Use the renamed `--per-file-caching` option instead. If this option is set, Pants will now run per every file, rather than per target.
See `--per-file-caching`.
