Instantiate an stdClass object from json schema specification in PHP -

(don't want reinvent wheel) thanks! edit: have @ this schema file contains example of want load , build object instances from. disclaimer: know json_encode / json_decode not i'm looking for. using i'd need traverse through returned schema object , create object/array based on schema read, not want. i don't think there's built-in way of doing this, should relatively trivial implement: function createobj( $json ) { $obj_schema = json_decode($json, true); $new_obj = new stdclass; foreach($obj_schema['properties'] $property) { $new_obj->{$property} = null; } return $new_obj; }

php - Is it a bug that 'assert' ignores the current namespace? -

should following problem considered normal behavior or bug? <?php namespace ns; function func () { echo "hello\n"; return true; } func(); // ok assert('func()'); // "call undefined function func()" assert assume behaving same way eval in switches execution global namespace when code passed evaluated. specifying namespace in call works expect: <?php namespace ns; function func () { echo "hello\n"; return true; } func(); // ok assert('ns\func()'); i believe normal behavior; assert built in function, , you're passing string evaluated. when execution passes inside of assert function, in different namespace (mainly global namespace).

plsql - Does converting Oracle .rdf files to .rep do anything different than changing the extension? -

why should we use native php gettext instead of gettexxt library -

i'm including gettext library in application. but, our team decided go native php gettext. gettext library accepts string , converts using "translate" function defined in library. how can shift native lib? performance? suggestions on using native lib. in advance. it performance , ease of use. when use external library inside php using system() e.g., pros able use of options, make power user. cons that, each time run it, have parsing of return string , figure out results , stuff, hassle , pretty error prone. when use language-binding of external library, cons confined api calls binding provides. pros return values, error status etc defined within api calls handling calls easier. this tradeoff , vary case case whether 1 should use native interfaces or execute library directly.

.net - How does System.ComponentModel.CancelEventHandler work? I dont understand what a cancelable event is? -

i strated developing forms in windows forms(c#) , having difficulty in understanding how system.componentmodel.canceleventhandler works , cancelable event means. this.txtname.validating += new system.componentmodel.canceleventhandler(this.txtboxempty_validating); this.txtaddress.validating += new system.componentmodel.canceleventhandler(this.txtboxempty_validating); i appreciate if can explain event handling. the implementation of textbox's validating event go like: string previoustext = this.text; string textthatwasentered = this.getinput(); // update text inputted value this.text = textthatwasentered; // validate inputted text, giving handlers chance cancel canceleventargs canceleventargs = new canceleventargs(); // call handlers, passing canceleventargs can set .cancel if needed this.onvalidating(this, canceleventargs); // if cancelled, reset text previous value if (canceleventargs.cancel) { this.text = previoustext; } so, it's way ...

c++ - Using a typedef as a variable name not generating any error -

considering structure of data: typedef struct { float x; float y; } point; and i'm using function permute coordinates: point permute(point m) { point n; n.x = m.y; n.y = m.x; return n; } why declaring variable name ( point ) typedef not giving error? int main(void) { point a; point b; int point = 7; a.x = 0; a.y = 1; b = permute(a); printf("a (%.2f, %.2f)\n", a.x, a.y); printf("b (%.2f, %.2f)\n", b.x, b.y); printf("point = %d\n", point); return 0; } output: http://ideone.com/wcxbjd a (0.00, 1.00) b (1.00, 0.00) point = 7 scope. an identifier declared in outer scope (in case, @ file scope, i.e., outside function) may redeclared in inner scope (in case, inside main function). inner declaration hides outer declaration until reach end of inner scope. this applies declarations in general, not typedef names. a simple example: #include <stdio.h> typedef struct { int x, y; } point; int m...

Python - Generate binary list with itertools -

i want generate following output: [11000] combinations these numbers, no doubles [11000] [01100] [00110] [00011] [10100] . . . but cannot figure out how that. in problem list has 365 values 20 ones. you have 365 possible positions place 20 ones. 1 way approach making 20-length combinations of 365 positions. an example of how in code: from itertools import combinations n = 365 r = 20 indexes in combinations(range(n), r): base = [0]*n in indexes: base[i] = 1 print(base) since "n choose r" problem, you'll have lots of possible combinations! calculate how many, use: n! / (r!(n-r)!) = 365! / (20!(365-20)!) = 426112827338828179808453831565930.

c++ - Two scenarios of strcmp -
