Go R1 Day 52

progress

• published extension pack for Go¹
• Learned about magic number linter in golanglint-ci. For instance this would be flagged as a bad practice (while not applicable for a simple test like this, having a const makes sense in almost all other cases).

func Perimeter(width float64, height float64) float64 {
    return 2 * (width + height)
}

• Learned a few extra linter violations and how to exclude including:
  • lll: for maximum line length
  • packagetest: for emphasizing blackbox testing.
  • gochecknoglobals: for ensuring global variables aren't used
  • nlreturn: for returning without a black line before. That's a "nit", but nice for consistency (though I'd like to see this as an autoformatted rule with fix applied.)
