v0.6.0

Overview

New Features

• Adds --preview flag. Going forward, many new features will be hidden behind this prior to a stable release.
• Adds autofixes.
  • A subset of rules can now be fixed automatically by passing --fix or --unsafe-fix (mostly style-based rules)
  • Fixable rules are highlighted in the output
  • See the new rules page for an overview of which rules are now fixable
• Adds many more output formats, including SARIF and GitHub/GitLab CI
• Adds rules to the modules category for checking accessibility in modules (both in preview mode)
  • missing-accessibility-statement requires you to explicitly declare the default accessibility to private or public
  • default-public-accessibility requires you to set the default accessibility to private
• Adds rules to the style category:
  • missing-double-colon requires variable declarations to include ::, e.g. integer :: i instead of integer i.
  • incorrect-space-before-comment requires at least two spaces before an inline comment.
• Adds rules to the typing category:
  • external-procedure warns for the use of procedures within implicit interfaces using the external declaration.
  • implicit-external-procedures warns when a bare implicit none is used instead of implicit none (type, external), which forbids implicit typing when calling external procedures.
• Adds the 'obsolescent' rule category for catching outdated Fortran features, with three new rules:
  • common-block
  • statement-function
  • entry-statement
• Adds an optional progress bar -- useful when running on very large projects or on slower hardware.
• The no-real-suffix rule has been upgraded, and no longer complains in cases where no precision would be lost, e.g:

use, intrinsic :: iso_fortran_env, only: dp => real64
real(dp), parameter :: x = 3.141592653589  ! Error, RHS is single precision, precision lost in assignment
real(dp), parameter :: x = 3.141592653589_dp  ! Okay
real(dp), parameter :: y = 1.0  ! Okay, no precision lost

• We have docs! 🎉

Bug-fixes

• trailing-whitespace and line-too-long can handle multibyte UTF-8 characters in strings and comments
• Correctly report number of files scanned on completion

Breaking changes

• The rule external-function has been renamed procedure-not-in-module to avoid confusion with the new external-procedure rule.
