meteor - Is there any way to disable var scoping? -

the file-level javascript variable scoping introduced in meteor 0.6.0 breaks projects , packages written in typescript (and coffeescript , other transpilers). there way disable it? for example, typescript code: declare var meteor: any; module model { export var players = new meteor.collection('players'); } generates javascript no longer works because model no longer considered global: var model; (function (model) { model.players = new meteor.collection('players'); })(model || (model = {})); prepending this.model = null; workaround it's redundant , have apply code used meteor (it's broken @ least 1 of meteorite packages). what reason introducing meteor specific javascript language semantics? its bit nice way because before having these files sharing variables bit odd. meteor treated every javascript file if one. having larger projects (>20 js files) made difficult modularize application i'm not sure typescript it's sug...

Ruby regex- does gsub store what it matches? -

c++ - Basic RValue method return -

assuming basic method: std::string stringtest() { std::string hello_world("testing..."); return std::move(hello_world); } how should use output: option a: auto& string_test_output=stringtest(); option b: auto string_test_output=stringtest(); is stringtest() temporary value? if so, option not safe. if it's not temporary value, have feeling option b cause copy. i still getting used rvalue references returning value still scary don't want copying occur or run unnecessary copying! the best way change method this: std::string stringtest() { std::string hello_world("testing..."); return hello_world; } there no need tell function returned object should rvalue, comes automatically value being temporary - is, not bound name @ call site. such, initialized value move-constructed (unless temporary inside function elided entirely), no need manually express such intention. also, since return type std::string , retur...

python - How to create a datastore_query.Order object for ndb Query constructor? -

i noticed @ https://developers.google.com/appengine/docs/python/ndb/queryclass , there optional argument ndb.query constructor allows specify order in query. argument must of type datastore_query.order, can't seem find documentation on object or how create it. specify list of model properties order by: property_list = [item.property1, item.property2] items = item.query(orders=order(property_list)) instead of: items = item.query().order(item.property1, item.property2) any ideas? i think you're looking datastore_query.compositeorder composed of propertyorder s of properties in list. source order subclasses seems explained quite well, , can take @ ndb.query.order() construct them, , object pass constructor. (i can't think of situation using .order() wouldn't suitable though, , simpler.)

selection - Make html select option drop down menu open by default -

when select box clicked, drop down list of options displayed. drop down list stays open until user clicks outside or selects 1 of options in drop down list. is there simple way of making drop down list displayed when user enters page? autofocus better. similar how amazon displays it's menu automatically. i understand make ul dropdown list + javascript , etc, wondering whether there way of doing select using html or javascript. you can simulate click on element, click on <select> won’t open dropdown. using multiple selects can problematic. perhaps should consider radio buttons inside container element can expand , contract needed.

java - putfield order of arguments -

in java bytecode "putfield" instruction expects top of stack value, , top-1 of stack reference. why not other way round ? it asked in lecture notes , cannot find answer. the order doesn't matter, since vm , compiler implemented either way. sun chose have lower arguments appear lower on stack. you can see not putfield , many other instructions, such array loading , storing , method invocation. obey same convention. explanation can think of is more intuitive way. if read out stack bottom top left right, arguments on stack have same order arguments in method signatures or original source code. if wanted other way, programmers have mentally treat stack reversed, isn't big deal, possibly less intuitive.
