Exceptions: 1. before block: {{{meth(args) { code } }}} instead of {{{meth args { code } }}} 2. as param: {{{meth1 arg1, arg2, meth2(argX, argY, argZ)}}} instead of {{{meth1 arg1, arg2, meth2 argX, argY, argZ}}} 3. around expressions: {{{meth(a ? b : c)}}} instead of {{{meth a ? b : c}}} 4. before method chaining: {{{meth1(a).meth2}}} instead of {{{meth1 a.meth2}}} 5. after super: {{{super(a, b, c)}}} instead of {{{super a, b, c}}} - use symbols instead of strings whenever possible (in case of immutable strings), specially in hash keys. Use to_s when necessary - in default parameteres, use {{{nil}}} instead of {{{''}}}. Example: {{{def fn astring = nil}}}. Use to_s when necessary. Motivation: {{{if astring}}} is better than {{{unless astring.empty?}}}. - within defs, duplicate arguments to avoid then be overwritten. Example: {{{ class X def fn a # uses a copy of a a = a.dup # modifies a with no worries a.delete.format.kill.zerofill.add(rand(42)).scramble end end a = 'hihaha' X.new.fn a puts a #=> 'hihaha' }}} Stay tuned with precedences! They rules the exceptions. - if you do the right way, you avoid unnecessary remarks to explain the exceptions. 1 0 0 0 0 language english 1 assunto ruby 1
