Fixed

v0.7.2

Compare Source

Added

• disable directives can now be a range, e.g. disable=SC3000-SC4000
• SC1143: Warn about line continuations in comments
• SC2259/SC2260: Warn when redirections override pipes

• SC2268: Warn about unnecessary x-comparisons like [ x$var = xval ]

Fixed

• SC1072/SC1073 now respond to disable annotations, though ignoring parse errors
  is still purely cosmetic and does not allow ShellCheck to continue.
• Improved error reporting for trailing tokens after ]/]] and compound commands
• #!/usr/bin/env -S shell is now handled correctly
• Here docs with \r are now parsed correctly and give better warnings

Changed

• Assignments are now parsed to spec, without leniency for leading $ or spaces
• POSIX/dash unsupported feature warnings now have individual SC3xxx codes
• SC1090: A leading $x/ or $(x)/ is now treated as ./ when locating files
• SC2154: Variables appearing in -z/-n tests are no longer considered unassigned
• SC2270-SC2285: Improved warnings about misused =, e.g. ${var}=42
