how to get active tab instantly in Chrome Extension -


i working on chrome extension. possible active tab info in current window instantly rather using "chrome.tabs.query()"?

if have timing constraint need active tab (not async) can maintain reference active tab listening active tab changes chrome.tabs.onactivated e.g.

var activetab; function updateactive(tab) {     activetab = tab; } function onactivated(info) {     chrome.tabs.get(info.tabid, updateactive); } function onupdated(info, tab) {     if (tab.active)         updateactive(tab); } chrome.tabs.query({active: true, lastfocusedwindow: true}, function(tabs) {     updateactive(tabs[0]);     chrome.tabs.onactivated.addlistener(onactivated);     chrome.tabs.onupdated.addlistener(onupdated); });

then when want tab use activetab.

note: handling multiple windows left excercise reader. see chrome.windows.onfocuschanged

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
