enumerations, modules , interfaces merged if multiple blocks defined within same common root. can't find official definition of common root in language specification. is more complicated than... either: the module, or the global scope (the complication can think of if module merged, members of parts of module being merged have same common root, zips go). is there other kind of common root? module x { export interface y { name: string; } } module x{ export interface y { age: number; } } // x.y has both name , age properties it's "common root" in graph theory sense of term, since combination of typescript modules or programs forms tree of declarations (because declaration has 1 parent). second half of spec section 2.3 ("declarations") defines how tree constructed in terms of establishing parent relationships. i think relevant phrase in spec here declarations merge if have "the same qualified...

in code, running local server (cocoahttpserver). when server receives request, creates thread , passes control method ( - (nsobject<httpresponse> *)httpresponseformethod:(nsstring *)method uri:(nsstring *)path , perhaps irrelevant here). i need read list of local assets , return result. api call ( [assetslibrary enumerategroupswithtypes:alassetsgroupall usingblock:^(alassetsgroup *group, bool *stop) ... ) asynchronous. since httpresponse needs wait until api call has finished, have created flag called _isprocessing , set before making api call. after call finished, unsetting flag , returning http request. code wait looks like: // api call non-blocking. hence, wait in loop until command has finished samcommand->isprocessing = yes; while (samcommand->isprocessing) { usleep(100*1000); } the api call calls delegate method upon finishing task follows: // called @ end of asynch operation (eg: reading local asset list) - (void) commanddidfinish { // flag op...

i'm having trouble app hanging on nsfetchrequest. i've been reading quite few hours. there apparently threading issue going on, can't figure out how fix it. i'm downloading json object server, parsing , storing in coredata model. occurs on background thread complete before app hangs. here code occurs: - (void) populateregistrationlist:(nsstring *) list script:(nsstring *)script { nsurl *url = [nsurl urlwithstring:[primary_url stringbyappendingstring:script]]; nsurlrequest *request = [nsurlrequest requestwithurl:url]; nsurlsessionconfiguration *configuration = [nsurlsessionconfiguration ephemeralsessionconfiguration]; nsurlsession *session = [nsurlsession sessionwithconfiguration:configuration]; nsurlsessiondownloadtask *task = [session downloadtaskwithrequest:request completionhandler:^(nsurl *localfile, nsurlresponse *response, nserror *error) { if (!error) { nsarray *jobj = [nsjsonserialization jsonobje...

i have set of data , map colour aesthetic around sort of "reference value" so: values below red values near blue values above green i still want show fact values on continuoum, using function cut() , using scale_colour_discrete not i'm looking for. here's example data: set.seed(123) x <- runif(100, min = 1, max = 10) y <- runif(100, min = 1, max = 10) test <- data.frame(x = x, y = y) test$colour <- runif(100, min = 1, max = 10) ggplot(test, aes(x = x, y = y, colour = colour)) + geom_point(size = 3) that produces following: i'm familiar scale_colour_gradient(low = "red", high = "green") , hoping more deliberately transition colours along desired value mapping make regions "pop" bit more visually. spacing not linear. in other words, reference value of 3, mapping this: value: 1 3 10 colour: red blue green is possible? i'd take alternative solutions accomplish visualization highlig...
