c# - How to get complex enum value string representation -

-

let's have enum:

[flags] public enum sometype {         val1 = 0,     val2 = 1,     val3 = 2,     val4 = 4,     val5 = 8,     val6 = 16,     = val1 | val2 | val3 | val4 | val5 | val6 }

and variables:

sometype easytype = sometype.val1 | sometype.val2; sometype complextype = sometype.all;

if want loop through values of first enum can do:

foreach(string s in easytype.tostring().split(',')) { ... }

however, when try apply same approach 'complextype' value 'all', of course valid because it's 1 of possible values of enum. but, there neat way see of values sometype.all created of? know make manual loop through values that:

if(complextype.hasflag(manualtype.val1) && ... 

var result = string.join(",",                  enum.getvalues(typeof(sometype))                      .cast<sometype>()                      .where(v => complextype.hasflag(v)));

you can write extension method avoid repeating yourself.

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."
