usage: gometalinter [<flags>] [<path>]

Aggregate and normalise the output of a whole bunch of Go linters.

Default linters:

      structcheck {path}
      :PATH:LINE:MESSAGE
  defercheck (github.com/opennota/check/cmd/defercheck)
      defercheck {path}
      :PATH:LINE:MESSAGE

      deadcode {path}
      :deadcode: (?P<path>[^:]+):(?P<line>\d+):(?P<col>\d+):\s*(?P<message>.*)
  vet (golang.org/x/tools/cmd/vet)
      go vet {path}
      :PATH:LINE:MESSAGE
  gotype (golang.org/x/tools/cmd/gotype)
      gotype {path}
      :PATH:LINE:COL:MESSAGE
  varcheck (github.com/opennota/check/cmd/varcheck)
      varcheck {path}

      :(?P<cyclo>\d+)\s+\S+\s(?P<function>\S+)\s+(?P<path>[^:]+):(?P<line>\d+):(?P<col>\d+)

Severity override map (default is "error"):

  deadcode -> warning
  gocyclo -> warning
  go-nyet -> warning
  errcheck -> warning
  golint -> warning
  varcheck -> warning
  structcheck -> warning

Flags:
  --help             Show help.
  --fast             Only run fast linters.
  -i, --install      Attempt to install all known linters.
  -u, --update       Pass -u to go tool when installing.
  -D, --disable=LINTER
                     List of linters to disable.
  -d, --debug        Display messages for failed linters, etc.
  -j, --concurrency=16
                     Number of concurrent linters to run.
  --exclude=REGEXP   Exclude messages matching this regular expression.
  --cyclo-over="10"  Report functions with cyclomatic complexity over N (using gocyclo).
  --sort=none        Sort output by any of none, path, line, column, severity, message.
  --linter=NAME:COMMAND:PATTERN
                     Specify a linter.
  --message-overrides=LINTER:MESSAGE
                     Override message from linter. {message} will be expanded to the original message.
  --severity=LINTER:SEVERITY
                     Map of linter severities.
