text.regex.tdfa.text 1 provides instances regexlike regex text using internal text types. can instances of classes data.text.lazy derived instances of data.text.internal ? how can improve code? import qualified data.text.lazy t import text.regex.tdfa import text.regex.base.context() import text.regex.base.regexlike() import text.regex.tdfa.text import data.function (on) (<?>) :: t.text -> t.text -> bool (<?>) = on (=~) t.tostrict i might missing something, seems have missed the module containing lazy text instances regex-tdfa classes . if that's what's happening, need change import text.regex.tdfa.text to import text.regex.tdfa.text.lazy note called text in module data.text.internal same called text in data.text -- i.e., it's "strict" text . lazy text type defined in different internal module (basically specialized list of strict texts.) it's not though these 2 ways of viewing same thing, if that's

i have number of preferences need set , want guide user through flow popping individual preference dialogs (listpreference, edittextpreference etc.), 1 @ time can create wizard-style ui . as user fills in pref, closes , next 1 opens up. as far know, user has click on preference dialog popup. is there way programmatically ? you can use onitemclick perform click on preference item. get preference position preference order. int position = findpreference("language").getorder(); language preference key. then, onitemclick on preference item position. getpreferencescreen().onitemclick(null,null,position,0);

i have domain classes need updated @ same time, want use transaction in order allow changes both or neither. example : i have 2 different domain classes (user, , follow) user currentuser =.. user targetuser = .. follow followuser = .. targetuser.follower = targetuser.follower + 1 currentuser.follow = currentuser.follow + 1 targetuser.save(flush:true) currentuser.save(flush:true) followuser.save(flush:true) i want of happen or if 1 fails none of happen , gets rolled back. how can in grails ? saw domainobject.withtransaction, have 2 different domain, should nested ? the proper solution move transactional code service. documentation outlines how create , use services controllers. that's proper solution. however, that's not way. have seen there ability run code within transaction scope using withtransaction. example (directly documentation ): account.withtransaction { status -> def source = account.get(params.from) def dest = account.get(params

so searching around , using command tr can convert lower case upper case , vice versa. there way both @ once? so: $ tr '[:upper:]' '[:lower:]' or $ tr a-z a-z will turn: "hello world abc" "hello world abc" but want do: "hello world abc" please help! =) this looking for: tr '[:upper:][:lower:]' '[:lower:][:upper:]'

i have qvector of qstrings , want remove element content, don't know how find index of it. know how can remove it? don't want iterate on , compare content value. my qvector declared follows: qvector <qstring> user_valid; and want remove content, example element value "marigold": user_valid.remove(user_valid.find("marigold"); thank in advance! ok, following if you: use qstringlist instead of qvector<qstring> has convenience methods can useful you; more common , hence comprehensive. spare 1 method call in case. just use removeone() and/or removeall() methods depending on exact scenario. therefore, writing this: qstringlist user_valid; user_valid << "marigold" << "cloud" << "sun" << "rain"; user_valid.removeone("marigold"); // user_valid: ["cloud", ,"sun", "rain"] if insist on using qvector<qstring>

here regex exclude special character other allowing few (-,%,:,@). want allow / getting issue return preg_replace('/[^a-za-z0-9_ %\[\]\.\(\)%:@&-]/s', '', $string); this works fine listed special character, but return preg_replace('/[^a-za-z0-9_ %\[\]\.\(\)%\\:&-]/s', '', $string); does not filter l chracter to. here link test: http://ideone.com/wxr0ka where not allow \\ in url. want dispaly url usual you're making mistake in entering http:// http:\\ regex needs include / in exclusion list. should work: function clean($string) { // replaces spaces hyphens. $string = str_replace(' ', '-', $string); // removes special chars. return preg_replace('~[^\w %\[\].()%\\:@&/-]~', '', $string); } $d = clean("this http://nice readlly n'ice 'test for@me to") ; echo $d; // this-was-http://nice-readlly-nice-test-for@me-to working demo

after uploading of file ftp server, file name showing ????????. file name contains cyrillic words. inside of file showing correct. should done show correct file names? code here: fileinfo fileinfo = new fileinfo(filepath); string filename = fileinfo.name.tostring(); webrequest requestftp = webrequest.create(incomingftppath + filename); requestftp.credentials = new networkcredential(ftpusername, ftppassword); requestftp.method = webrequestmethods.ftp.uploadfile; filestream fstream = fileinfo.openread(); int bufferlength = 2048; byte[] buffer = new byte[bufferlength]; stream uploadstream = requestftp.getrequeststream(); int contentlength = fstream.read(buffer, 0, bufferlength); while (contentlength != 0) { uploadstream.write(buffer, 0, contentlength); contentlength = fstream.read(buffer, 0, bufferlength); } uploadstream.close(); fstream.

so worked in multi language project in laravel, create files in lang folder , when change language change successfully, when tried change view doesn't work, code change local language : <li><a onclick="{{app::setlocale('fr');}};location.reload(true);">francais</a></li> <li><a onclick="{{app::setlocale('en');}};location.reload(true);">english</a></li> app::setlocale('en'); isn't generate js code change language, set language current application, renders view.

okay, i've tried implement delegate method on uiimagepickercontroller stated @michaelking in previous post of mine. - (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info { [picker dismissviewcontrolleranimated:false completion:nil]; image = [info objectforkey:@"uiimagepickercontrolleroriginalimage"]; } however, following error in code: warning: attempt present <uiimagepickercontroller: 0xc464f10> on <rpflipsideviewcontroller: 0xc66a270> view not in window hierarchy! i don't understand means, , searching online, haven't found i've been able understand. can please clarify? maybe still don't understand whole delegate thing? here previous post, reference: how reference picture took in ios? the view controller's view must on screen (not visible) must in hierarchy somewhere. without being in current view hierarchy there no graphics context in present picker.

more clarity question actual question have found solution. don't understand reasoning... using sqllite 3.8.3.1 using sqlite-net 2.1 i see distinct difference between running .where(lambda).firstordefault() running .firstordefault(lambda) . as far experience linq goes, database linq providers treat both of these same ( .firstordefault(lambda) may little faster if it's optimized properly, , large, these 2 calls take same time run). however, in sqlite-net, seeing following results on table ~40,000 records in it: when running .firstordefault(x => x.id == id) , seeing time taking on core-i7 between 2200ms 3700ms . on surface rt (1st gen) takes around 20,000ms-30,000ms.. when running .where(x => x.id == id).firstordefault() , seeing time taking on same core-i7 between 16ms-20ms . on surface rt, takes around 30ms. my question whether bug, or if that's conscious design decision. if it's design decision - love understand reasoning behind it. .w

in scenario have ticket model , ticketreply model. i can grab replies ticket $ticket->replies . considering status 1 or 3 of ticket or reply means state open/unresolved, how find total of tickets open eloquent way. $tickets = ticket::all(); $tickets_open = 0; foreach($tickets $t) { $tickets_open++; if(($t->replies()->first()->status == 2) || ($t->status == 2)) { $tickets_open--; } } return $tickets_open; is there more efficient way of doing eloquent ? since query run each iteration. if there not, can convert $tickets array , iterate it. update: $t->replies()->first()->status causing 1+n or without eager loading. i changed $t->replies->first()->status , 1+n gone. rookie mistake believe. you can use eager loading reduce number of queries. $tickets = ticket::with('replies')->get(); doing this, instead of running 1+n queries, end running 2 sql queries: select * tickets se
