Changelog

flint (development version)

New features

• 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.

Bug fixes

• 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.

flint 0.1.2

New features

• sample(n, m) is now reported and can be rewritten as sample.int(n, m) when n is a literal integer.

Bug fixes

• 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').

flint 0.1.1

Bug fixes

• 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().

flint 0.1.0

New features

• New linters: rep_len_linter(), sample_int_linter() and which_grepl_linter().
• Add a menu or an error if fix() and its variants would change some unstaged files.
• update_flint() now updates all rules and doesn’t only add new rules anymore.

flint 0.0.9

New features

• New linters: condition_message_linter() and expect_identical_linter().
• Rewrote vignette on adding new rules.
• setup_flint() now puts built-in rules in flint/rules/builtin.

flint 0.0.8

New features

• New linters: expect_comparison_linter and package_hooks_linter.
• Add argument verbose to lint_package() and lint_dir().
• Better message when no lints can be fixed.
• Add one case in seq_linter where seq_len(x) is faster than seq(1, x).
• Better handling of exclude_path.

flint 0.0.7

New features

• Set up the Github Actions workflow for flint (#22).
• New linters function_return_linter and todo_comment_linter.
• Better support for library_call_linter.
• Add argument overwrite to setup_flint_gha().

flint 0.0.6

New features

• New linter redundant_equals_linter.
• Better support for matrix_apply_linter.

flint 0.0.5

New features

• Deactivated absolute_path_linter in default use as there are too many false positives.
• New linter unnecessary_nesting_linter.
• Add messages for lint() and fix() showing the number of files checked, lints found and/or fixed.

Bug fixes

• More robust detection of allowed usage of T and F in formulas.
• Use the pipe in the replacement for lengths_linter if it was already present in code.

Misc

• Add links to lintr documentation in the manual pages.

flint 0.0.4

New features

• New linters: for_loop_index,missing_argument.
• fix() has a new argument force (FALSE by default). This is useful if Git was not detected, fix() would modify several files, and it is run in a non-interactive context. In this situation, set force = TRUE to apply the fixes anyway.
• Add cli messages informing how many files are checked, and how many contain lints (for lint_* functions) or were modified (for fix_* functions).
• Better coverage of the length_test linter.

Bug fixes

• Allow usage of T and F in formulas (#33).

flint 0.0.3

New features

• New linters: absolute_path, duplicate_argument, empty_assignment, expect_length, expect_not, expect_null, expect_true_false, expect_type, literal_coercion, nested_ifelse, sort, undesirable_operator.
• Added a contributing guide.
• Better docs for fix() and its variants.
• Using fix() on several files without using Git now opens an interactive menu so that the user confirms they want to run fix(). In case of non-interactive use, this errors.
• Ignore lines following # nolint for compatibility with lintr.

Bug fixes

• Fix a few false positives (#23, #24, #27).

flint 0.0.2

New features

• 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().

Bug fixes

• Do not lint for 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.

flint 0.0.1

• First Github release.
