Which style of Ruby string quoting do you favour?

Question

Which style of Ruby string quoting do you favour? Up until now I\'ve always used \'single quotes\' unless the string contains certain escape sequences or interp

Answer 1

I use single quotes unless I need interpolation. The argument about it being troublesome to change later when you need interpolation swings in the other direction, too: You have to change from double to single when you found that there was a # or a \ in your string that caused an escape you didn't intend.

The advantage of defaulting to single quotes is that, in a codebase which adopts this convention, the quote type acts as a visual cue as to whether to expect interpolated expressions or not. This is even more pronounced when your editor or IDE highlights the two string types differently.

I use %{.....} syntax for multi-line strings.
