To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!

Use
%()
(it's a shorthand for%Q
) for single-line strings which require both
interpolation and embedded double-quotes. For multi-line strings, prefer heredocs.# bad (no interpolation needed) %(<div class="text">Some text</div>) # should be '<div class="text">Some text</div>' # bad (no double-quotes) %(This is #{quality} style) # should be "This is #{quality} style" # bad (multiple lines) %(<div>\n<span class="big">#{exclamation}</span>\n</div>) # should be a heredoc. # good (requires interpolation, has quotes, single line) %(<tr><td class="name">#{name}</td>)
Avoid
%q
unless you have a string with both'
and"
in
it. Regular string literals are more readable and should be
preferred unless a lot of characters would have to be escaped in
them.# bad name = %q(Bruce Wayne) time = %q(8 o'clock) question = %q("What did you say?") # good name = 'Bruce Wayne' time = "8 o'clock" question = '"What did you say?"'
Use
%r
only for regular expressions matching more than one '/' character.# bad %r(\s+) # still bad %r(^/(.*)$) # should be /^\/(.*)$/ # good %r(^/blog/2011/(.*)$)
Avoid the use of
%x
unless you're going to invoke a command with backquotes in
it(which is rather unlikely).# bad date = %x(date) # good date = `date` echo = %x(echo `date`)
Avoid the use of
%s
. It seems that the community has decided
:"some string"
is the preferred way to create a symbol with
spaces in it.Prefer
()
as delimiters for all%
literals, except%r
. Since
braces often appear inside regular expressions in many scenarios a
less common character like{
might be a better choice for a
delimiter, depending on the regexp's content.# bad %w[one two three] %q{"Test's king!", John said.} # good %w(one two three) %q("Test's king!", John said.)
