objective c - setting BOOL variable inside block -


i'm trying set bool value defined in class inside block, can't see able set it. code.

 __weak __block sptween *tween2weak = tween;     __block bool buttonscroll2 = buttonscroll;      tween.oncomplete = ^{         [sparrow.juggler removeobject:tween2weak];         buttonscroll2 = no;     };

i presume when buttonscroll2 = no, im doing setting separate variable , not original, how original inside block then?

you correct, once value of buttonscroll gets copied buttonscroll2, changes buttonscroll2 have no effect on original buttonscroll.

if buttonscroll instance variable of object, should able access using __weak self pattern:

__weak __block sptween *tween2weak = tween; __weak typeof(self) weakself = self; tween.oncomplete = ^{     [sparrow.juggler removeobject:tween2weak];     myclass *strongself = weakself;     strongself->buttonscroll = no; };

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
