New linter stopifnot_all_linter() to detect calls to stopifnot(all(...))
since the all() is unnecessary. This has an automatic fix available.
New linter list_comparison_linter() to detect a comparison with a list,
e.g. lapply(x, sum) > 10. No automatic fix available.
Line breaks are removed from multi-line messages reported by lint*
functions.
matrix_apply_linter now detects when 1L and 2L are used in the MARGIN
argument.
any_is_na_linter now reports cases like NA %in% x, and can fix them to be
anyNA(x) instead.
library_call_linter no longer reports cases where library() calls are
wrapped in suppressPackageStartupMessages().
Nested fixes no longer overlap. The fix*() functions now run several times
on the files containing nested fixes until there are no more fixes to apply.
This can be deactivated to run only once per file by adding rerun = FALSE
(#61).
any_is_na_linter wrongly reported cases like any(is.na(x), y). Those are
no longer reported.
No longer lint and fix expect_equal(length(x), length(y)), which is more
readable than expect_length(x, length(y)).
No longer lint and fix expect_equal(names(x), names(y)), which is more
readable than expect_named(x, names(y)).
sample(n, m) is now reported and can be rewritten as sample.int(n, m)
when n is a literal integer.Rule names have been harmonized to use a dash instead of underscore, e.g.
any_duplicated-1 instead of any_duplicated_1.
Replacement of redundant_ifelse_linter of the form
ifelse(cond, FALSE, TRUE) now works (#57).
absolute_path_linter was deactivated in 0.0.5 but was still reported. It is
now properly ignored.
Code like expect_equal(typeof(x), 'class') was modified twice by
expect_identical_linter and expect_type_linter, which lead to a wrong
rewrite. It is now replaced by expect_type(x, 'class').
fix() and lint() now work correctly when several paths are passed.
fix_package() and lint_package() used all R files present from the root
path, even those in folders that are not typical of an R package.
fix_dir() and fix_package() now have the arguments force and verbose,
like fix().
rep_len_linter(), sample_int_linter() and
which_grepl_linter().fix() and its variants would change some unstaged
files.update_flint() now updates all rules and doesn't only add new rules anymore.condition_message_linter() and expect_identical_linter().setup_flint() now puts built-in rules in flint/rules/builtin.expect_comparison_linter and package_hooks_linter.verbose to lint_package() and lint_dir().seq_linter where seq_len(x) is faster than seq(1, x).exclude_path.flint (#22).function_return_linter and todo_comment_linter.library_call_linter.overwrite to setup_flint_gha().redundant_equals_linter.matrix_apply_linter.absolute_path_linter in default use as there are too many false

non-interactive use, this errors.# nolint for compatibility with lintr.New linters: expect_named, numeric_leading_zero, outer_negation,
redundant_ifelse, undesirable_function, unreachable_code.
fix_dir(), fix_package(), lint_dir(), lint_package() now have arguments
to exclude paths, linters, and use cache.
Removed browser linter (it is now part of undesriable_function).
Add support for a flint/config.yml file that contains the list of linters
to use so that one doesn't need to constantly specify them in lint() or fix().
x %in% class(y) where x is not a string as this is not
equivalent in some cases. Thanks Vincent Arel-Bundock for spotting this.
