javascript - Canceling an OpenLayers.Map current panTo tween if user begins dragging map -


i've noticed if user drags map before panto function completes, map continue pan in previous pan direction.

here's quick jsfiddle high pan duration make effect easy reproduce:

http://jsfiddle.net/a8kk4/58/

map.panto( xy ); // code jsfiddle link

is there straight forward way cancel current panning event if user begins drag map?

i fixed it, though i'm not sure if best way. basically, did put call pantween.stop in map's moveend event, set pantween's callback null, otherwise, loop continues -- see openlayers.tween stop`function here: http://trac.osgeo.org/openlayers/browser/trunk/openlayers/lib/openlayers/tween.js

in summary, added these 3 lines @ end of init function:

map.events.register('moveend', map, function(){                    this.pantween.callbacks=null;         this.pantween.stop();             });

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
