does flyway have manage objects in database schema? or permissible have objects dropped/recreated outside of flyway system, example tables containing lookups generated , populated separately? as long unmanaged db objects not connected managed ones, (technically) not problem. if connected each other, have problems in scenarios: setting new database flyway scratch won't work because flyway migration cannot intercepted other unmanaged scripts. if unmanaged objects not compatible @ time, break flyway migration @ point. in case, if start using unmanaged db scripts, won't have reproducible migration path database anymore, 1 of key features of flyway.

i writing replacement plone dialog infrastructure. personal use , fun, available on github collective.js.jqueryuidialog. currently i'm struggling manage initialization tinymce editor in dialogs. i tried missing scripts getscript, stuck. googled , found init hooks, 1 $(document).bind('loadinsideoverlay', function() { $('textarea.mce_editable').each(function() { var config = new tinymceconfig($(this).attr('id')); config.init(); }); }); but none worked. any ideas or recommendations read further? update i updated products.tinymce version 1.3.3 , proceeded through upgrade steps in zmi. other functionality still working (yeehaa). i realized, call seems have changed, since pages tinymce on it, issue get command view named tiny_mce_gzp.js seems deliver actual configured editor portal. actually digging source find call , copy it's behavior.

is there opposite of liftio ? i'm using websockets, , want able listen messages server in separate thread. here's i'm doing: import network.websockets import qualified data.text t import control.monad.io.class import control.monad import control.concurrent import control.applicative printmessages :: websockets hybi00 () printmessages = forever $ resp <- receivedatamessage liftio $ print resp run :: websockets hybi00 () run = liftio . forkio $ printmessages forever $ line <- liftio getline sendtextdata . t.pack $ line main = connect "0.0.0.0" 8080 "/" run so printmessages listens messages server , keeps printing them out. problem is, forkio expects function returns io () . there way me run printmessages in io monad? if i'm understanding right, reason want receive messages in thread because main thread waiting user input send. from @ the documentation , seems you'll have easier time if rev...

i've noticed projects such bundler require spec_helper in each spec file i've noticed rspec takes option --require , allows require file when rspec bootstrapped. can add .rspec file, added whenever run rspec no arguments. are there disadvantages using above method might explain why projects such bundler choose require spec_helper in each spec file? i don't work on bundler can't speak directly practices. not projects check-in .rspec file. reason file, current convention, has personal configuration options general output / runner preferences. if required spec_helper there, others wouldn't load it, causing tests fail. another reason, not tests may need setup performed spec_helper . more there have been groups of rubyists trying move away loading many dependencies test. making explicit when spec_helper required in test people have idea may going on. also, running single test file or directory doesn't need setup faster. in reality, if of te...

i'm trying format number plates - need find last digit in string , add space after it, e.g. t4max = t4 max t53tes = t53 tes i'm assuming i'll have use preg_replace - i've tried below find position in string of last digit, returns empty array. preg_match('/(0-9])/', $plate, $matches, preg_offset_capture); any ideas? that's easy: $str = 't4max'; $str_with_space = preg_replace('~\d(?=\d*$)~', '$0 ', $str); online demo: http://ideone.com/mqqqsh regex explanation: ~\d(?=\d*$)~ expression means - digit \d followed not digit \d end of string.

i have 3-dimensional array. think of brick. there 24 possible rotations of brick (that keep edges parallel coordinate axes). how generate corresponding 3-dimensional arrays? a die (half pair of dice) handy observing 24 different orientations, , can suggest operation sequences generate them. see of 6 faces can uppermost, , sides below can rotated 4 different cardinal directions. let denote 2 operations: “ turn ” , “ roll ”, turn rotates die z axis 1 cardinal next, , roll rotates die 90° away you, away-face becomes bottom face , near face top. these operations can expressed using rotation matrices mentioned in answer of felipe lopes, or can expressed simple functions when given (x,y,z) return (-y,x,z) or (x,z,-y), respectively. anyhow, if place die 1 on near face, 2 @ right, , 3 on top, find following sequence of steps generates twelve different orientations 1, 2, or 3 spots on top: rtttrtttrttt. sequence rtr exposes 6, 4, 5 1, 2, 3 were, , repeat of sequence rtttrt...

i'm in process of moving files onto computer, , 1 thing transfer data in mysql database. want dump databases .sql files, have create database db_name including in file, way have import file mysql without having manually create databases. there way that? by default mysqldump creates create database if not exists db_name; statement @ beginning of dump file. [ edit ] few things mysqldump file , it's options: --all-databases , -a dump tables in databases. same using --databases option , naming databases on command line. --add-drop-database add drop database statement before each create database statement. option typically used in conjunction --all-databases or --databases option because no create database statements written unless 1 of options specified. --databases , -b dump several databases. normally, mysqldump treats first name argument on command line database name , following names table names. option, treats name arguments database names....

i attempting create pong game in c# visual c# express 2010. part, have main idea of game finished, have issue ball moving. have create loop, this: public void ballset() { if (!values.ispaused) { while(true) { if (values.totaltime.elapsed.seconds > 1) { values.totaltime.restart(); ballmove(50, 50); } } } } public void ballmove(int factorx, int factory) { values.balllastx = ball.location.x; values.balllasty = ball.location.y; this.ball.location = new point(this.ball.location.x + factorx, this.ball.location.y + factory); } the "ballmove(50, 50);" testing purposes @ moment. issue when ballset() called, form seems close code of 0, meaning there no error. call ballset() on here. public pong() { initializecomponent(); ballset(); values.totaltime.start(); } i have checked , program work when remove while loop in ballset(), if statement chec...

is possible detect activex controls active in ie 8/9/10 using javascript (or other technology - possibly java?), in way more extensible , dynamic attempting instantiate specific activex object around try-catch block? far, appears way achieve solution, solution not extensible , require additional code maintenance when newer activex plugins released. it nice able detect plugins similar in way js navigator.plugins array, far can tell, there no comparable way activex controls. you create activex control had ability detect presence of other activex controls, ie not expose api you. catch-22.

i'm looking efficient way take javascript string , return of scripts occur in string. full utf-16 including "astral" plane / non-bmp characters require surrogate pairs must correctly handled. possibly main problem since javascript not utf-16 aware. it has deal codepoints no fancy awareness of complex scripts or grapheme clusters necessary. (this obvious of anyway.) example: stringtoiso15924("παν語"); would return like: [ "grek", "hani" ] i'm using node.js , unicode libraries such xregexp , unorm don't mind adding other libraries might handle or ease such feature. i'm not aware of javascript library can character properties such script codes, second part of problem. the third part of problem avoid inefficiencies. i answered a similar question , @ least related. in this pastebin (looooong) function returns script name character. should easy modifiy accommodate string.
