ruby - What is the value in having several, equally abstract, syntactic variations for coding something? -

-

i reading on ruby. think nice language, bit bothered having many equivalent ways, slightly different in syntax, coding same action. example, unless conditional statement, equivalent writing if !conditional.

to me, not add expressive power, makes more taxing follow other people's code. there benefit missing (other catering different tastes, don't find convincing, since people don't reject language because syntactic keywords didn't match taste)?

there more examples of in every language. using example because though particularly lacking reasonable defense.

catering different tastes explanation. philosophy adapted perl , it’s known timtowtdi (there's more 1 way it).

this have advantages, example facilitates creation of rich domain-specific languages within ruby, since existing syntax constructs can combined in new, interesting ways.

but technique has many detractors, , python in particular strives opposite:

there should one-- , preferably 1 --obvious way it.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
