Changelog

0.3.0

Breaking changes

• Jarl now excludes by default file paths matching the following patterns: .git/, renv/, revdep/, cpp11.R, RcppExports.R, extendr-wrappers.R, and import-standalone-*.R.

  A new CLI argument --no-default-exclude can be used to check those files as well. This argument overrides the default-exclude = true option when set in jarl.toml (#178, @novica).

Features

• --output-format json now contains two fields diagnostics and errors (#219).
• Better support for namespaced function calls, both when reporting violations and when fixing them (#221).
• The class_equals rule now also reports cases like identical(class(x), "foo") and identical("foo", class(x)) (#234).
• New rules:
  • expect_s3_class (#235)
  • expect_type (#226)
  • fixed_regex (#227)
  • sprintf (#224)
  • string_boundary (#225)
  • vector_logic (#238)

Fixes

• # nolint comments are now properly applied to nodes that are function arguments, e.g.

  foo(
    # nolint
    any(is.na(x))
  )

  does not report a violation anymore (#229).

Other changes

• expect_named no longer reports cases like expect_equal(x, names(y)) because rewriting those as expect_named(y, x) would potentially change the intent of the test and the way it is read (#220).

0.2.1

Other

• Important performance improvement when using --fix, in particular in projects with many R files (#217).

0.2.0

Breaking changes

• For consistency between CLI arguments and jarl.toml arguments, the following CLI arguments are renamed (#199):
  • --select-rules becomes --select
  • --ignore-rules becomes --ignore
  • --assignment-op becomes --assignment

Features

• New argument extend-select in jarl.toml and --extend-select in the CLI to select additional rules on top of the existing selection. This can be useful to select opt-in rules in addition to the default set of rules (#193).
• Added support for seq and seq2 rules (#187).
• Added support for several rules related to testthat. Those rules are disabled by default and can be enabled by combining select or extend-select with the rule name or the TESTTHAT group rule name. Those rules are:
  • expect_length (#211)
  • expect_named (#212)
  • expect_not (#204)
  • expect_null (#202)
  • expect_true_false (#191)

Fixes

• implicit_assignment no longer reports cases inside quote() (#209).

Documentation

• Added section on Neovim to the Editors page (#188, @bjyberg).
• Added page “Tutorial: add a new rule” (#183).

0.1.2

Features

• Added support for list2df rule (#179).
• Added support for browser rule (#185, @jonocarroll).
• Added support for system_file rule (#186).

Fixes

• (Hopefully) Fixed wrong printing of ANSI characters in multiple terminals on Windows (#179, thanks @novica for the report).

Documentation

• Added sections on RStudio and Helix to the Editors page.
• Added installation instructions using Scoop on Windows.

0.1.1

Fixes

• Fix discovery of jarl.toml by the Jarl extension (#175, thanks @DavisVaughan for the report).
• Rule duplicated_argument no longer reports cli_ functions where multiple arguments have the same name (#176, thanks @DavisVaughan for the report).

Documentation

• The docs of assignment rule now explain how to change the preferred assignment operator.
