lint

only

--lint-only="['<str>', '<str>', ...]"

PANTS_LINT_ONLY

Only run these linters and skip all others.

The linter names are outputted at the final summary of running this goal, e.g. flake8 and shellcheck. You can also run lint --only=fake to get a list of all activated linters.

You can repeat this option, e.g. lint --only=flake8 --only=shellcheck or lint --only=['flake8', 'shellcheck'].

skip_formatters

--[no-]lint-skip-formatters

PANTS_LINT_SKIP_FORMATTERS

If true, skip running all formatters in check-only mode.

FYI: when running pants fmt lint ::, there should be diminishing performance benefit to using this flag. Pants attempts to reuse the results from fmt when running lint where possible.

skip_fixers

--[no-]lint-skip-fixers

PANTS_LINT_SKIP_FIXERS

If true, skip running all fixers in check-only mode.

FYI: when running pants fix lint ::, there should be diminishing performance benefit to using this flag. Pants attempts to reuse the results from fix when running lint where possible.

batch_size

--lint-batch-size=<int>

PANTS_LINT_BATCH_SIZE

The target number of files to be included in each linter batch.

Linter processes are batched for a few reasons:

1. to avoid OS argument length limits (in processes which don't support argument files)
2. to support more stable cache keys than would be possible if all files were operated on in a single batch.
3. to allow for parallelism in linter processes which don't have internal parallelism, or -- if they do support internal parallelism -- to improve scheduling behavior when multiple processes are competing for cores and so internal parallelism cannot be used perfectly.

In order to improve cache hit rates (see 2.), batches are created at stable boundaries, and so this value is only a "target" batch size (rather than an exact value).
