v0.9.0

Compare Source

Added

• SC2316: Warn about 'local readonly foo' and similar (thanks, patrickxia!)
• SC2317: Warn about unreachable commands
• SC2318: Warn about backreferences in 'declare x=1 y=$x'

• SC2321: Suggest removing $((..)) in array[$((idx))]=val

Fixed

Changed

• ShellCheck now has a Data Flow Analysis engine to make smarter decisions
  based on control flow rather than just syntax. Existing checks will
  gradually start using it, which may cause them to trigger differently
  (but more accurately).
• Values in directives/shellcheckrc can now be quoted with '' or ""

v0.8.0

Compare Source

Added

• disable=all now conveniently disables all warnings
• external-sources=true directive can be added to .shellcheckrc to make
  shellcheck behave as if -x was specified.

  suppressed exit codes (SC2312).
• Optional require-double-brackets for recommending [[ ]] (SC2292).
• SC2286-SC2288: Warn when command name ends in a symbol like /.)'"

• SC2296-SC2301: Improved warnings for bad parameter expansions
• SC2302/SC2303: Warn about loops over array values when using them as keys
• SC2304-SC2306: Warn about unquoted globs in expr arguments
• SC2307: Warn about insufficient number of arguments to expr
• SC2308: Suggest other approaches for non-standard expr extensions
• SC2313: Warn about read with unquoted, array indexed variable

Fixed

• SC2102 about repetitions in ranges no longer triggers on [[ -v arr[xx] ]]
• SC2155 now recognizes typeset and local read-only declare statements
• SC2181 now tries to avoid triggering for error handling functions
• SC2290: Warn about misused = in declare & co, which were not caught by SC2270+
• The flag --color=auto no longer outputs color when TERM is "dumb" or unset

Changed

• SC2048: Warning about $* now also applies to ${array[*]}
• SC2181 now only triggers on single condition tests like [ $? = 0 ].
• Quote warnings are now emitted for declaration utilities in sh

Removed
