i'd create new command compiles current *.tex file , shows in pdf viewer (i'm using osx due use preview). here attempt: autocmd bufreadpost,bufwritepost *.tex nmap <leader>b :!temp=% && pdf=${temp:0: ${#temp}-4 } && echo $temp && "/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode % && open $pdf && unset temp pdf<cr> temp file name of mit *.tex file. pdf file name of *.pdf. however when execute following error message: 499: empty file name '%' or '#', works ":p:h" is there different method shorten string without using '#'? solution: autocmd bufreadpost,bufwritepost *.tex nmap <leader>b :!pdf="%<.pdf" && "/usr/texbin/pdflatex" -synctex=1 -interaction=nonstopmode "%" && open "$pdf" && unset pdf<cr> why not use error message's suggestion , set pdf in vimscript instead

so let's i'm creating list sections. is preferred keep array of objectid 's in parent element. var listschema = new mongoose.schema({ sections : {type: [objectid], ref : "section"} }); or keep reference parent's objectid in each item , find var sectionschema = new mongoose.schema({ list : {type: objectid, ref : "list"} }); (or both maximum flexibility?) i've been doing second way, i'm thinking might stuck in relational db paradigm. because once there multiple levels of nesting seems pretty dirty callbacks data want. , don't take advantage of populate function. assuming each object has 1 parent, it's easier keep parent id in child object. although, if you're trying find children of object, rather parent, easier store array of children ids in parent object. i'm not sure of availability of maps in language you're using, youcan use maps link parent ids children ids. works storing parent

there may simple way troubled me. i'm trying splice 2-dimension array below : removechild(test[1].splice(currshape, 1)); but won't splice it, , me following error : type coercion failed: cannot convert []@29258d59 flash.display.displayobject. any helps appreciated. your call splice() working. note splice() method returns array containing elements removed original array . you pass array splice() returned argument removechild() . , removechild() method failing ... expects the argument displayobject not array , , throws exception. you can change code following, written on 2 lines clarity: var removeditems:array = test[1].splice(currshape, 1); removechild( removeditems[0] );

i have form has sections split tabs. entire form should validated when user submits form (i.e. input has focus , press enter or save button pressed) , i'd validate elements on first tab on click event of tab (other first 1 obviously) disallow moving tab before first tab's elements validated. problem seem continue running after first attempt @ validating rules , elements validated set , don't updated based on passing of different set of rules. edit: clarify, can more see issue if click tab 2 fill out text 1 , text 2 , hit save, exact opposite. any thoughts on matter appreciated. in advance! this based on jquery validate plugin here: http://jqueryvalidation.org/ here's link fiddle: http://jsfiddle.net/fsb69/ <html> <head> <script type="text/javascript" src="jquery-1.7.2.js"></script> <script type="text/javascript" src="jquery.validate.js"></script> <script type="t

all less documentation , tutorials use #namespace > .mixin() syntax when takes namespaces. find myself more comfortable .namespace.mixin() syntax, i.e.: .namespace() { .mixin() { foo: bar; } } #usage {.namespace.mixin()} am missing something? there difference between these 2 variants (in partucular, way mixins/variables affect scope , vice versa)? or kind of historically rooted tradition? you're right, ".namespace > .mixin", ".namespace.mixin" , ".namespace .mixin" different beasts when used selectors. things seem dissimilar when goes mixin invoke/expansion. cannot craft example where: "#usage {#namespace > .mixing}" "#usage {#namespace.mixing}" "#usage {#namespace .mixing}" etc. produce non equal output, assuming .mixin defined parametric ruleset. same ".namespace". e.g.: /* */ #namespace { .mixin1() { foo1: bar; .mixin1() { foo2: bar;

this full script: #!/usr/bin/expect set a1 "aaa" set a2 "bbb" set a3 "ccc" {set b 1} {$b<4} {incr b} { send a$b } the output is: a1a2a3 what wanted values for $a1 $a2 $a3 how fix ? someone recommended "eval" eval send "a$b" which not seem working, outputs same thing above. it want array : array set myarr { a1 "aaa" a2 "bbb" a3 "ccc" } foreach {var value} [array myarr] { puts "color: $var count: $value" } this code outputs me: color: a3 count: ccc color: a1 count: aaa color: a2 count: bbb so don't have order. or you're looking list : set mylist {"aaa" "bbb" "ccc"} lappend mylist "ddd" foreach elem $mylist { puts $elem } this output exactly: aaa bbb ccc ddd this page should make such things pretty clear you

i looking sort sql results via sql query presumably sort of nested order by/order within order clause i have following data: term user item_no score man sam 2 null man sam 1 170 man jerry 1 100 man jerry 2 null man sam 3 null and wish obtain following order results: term user item_no score man sam 1 170 man sam 2 null man sam 3 null man jerry 1 100 man jerry 2 null the results must sorted firstly score (stored in item_no 1 each user) descending. further items created user seleted term must picked , inserted directly following , in item_no order. my current query looks this: select * table term = 'man' order score desc, item_no asc ...however results follows: term user item_no score man sam 1

assuming have so interface interface isinterface {} implementation classes public concreteclassa implements isinterface { injectora a, injectorb c, injectorc c; @inject concreteclassa(injectora a, injectorb b, injectorc c) { this.a = a; this.b = b; ..... } } public concreteclassb implements isinterface { injectora a, injectorb b, injectorc c; @inject concreteclassb(injectora a, injectorb b, injectorc c) { this.a = a; this.b = b; ..... } } ..and decide use gwt deferred binding in gwt module.gwt.xml //pseudo xml configuration if (type isinterface) if toggle == use concreteclass else use concreteclassb now, when try run this. won't work because gwt expected concrete class , b have default 0 constructor. so, tried following on concrete class @inject injectora a; @inject injectorb b; @inject injectorc c; concreteclassa() { } which bypass 0 constructor error gives me nullpointerexception when try use a, b or c. 1 way m

i have fresh provisioned instances of apache , postgres set go. restore dump or mount logical volume data postgres instance. likewise, i'd ensure dump written out or volume unmounted when bring instance down. can use logical volume way? how should approach? i see this: how handle data such mysql, web sites sources vagrant? the other answer had following suggestions. below discuss implications postgresql. in current version of vagrant (1.0.3), have 2 main options: use shared folders. can put mysql data directory shared folder data comes onto host machine. con of shared folders quite slow compared native vm filesystem in virtualbox, , can run weird permission issues well. setup task (rake, make, etc.) copy mysql data shared folder on demand. then, before decide destroy vm, can run task export data shared folder, can reimport data when bring vm up. the shared folders approach may work, if need extremely careful file permissions. post

this frustrates me lot since moved pdo i have this: $sql = "select * $table id=:id"; $this->stmt = $this->dbh->prepare($query); $this->stmt->bindvalue($param, $value, $type); bindvalue(:id => $this->user_id); $this->stmt->execute(); now select runs, doesnt break dont expected results, if echo $this->stmt this: pdostatement object ( [querystring] => update `users` set user_active= :user_active, user_activation_hash= :user_activation_hash user_id = :user_id , user_activation_hash = :verification_code ) now looks problem values passed, instead of passing number might have messed quotes , passed $id string , didnt evaluate variable cannot figure way out see actual statement values were. there must easier way, simple standard mysql assign query variable , echo out or use or die mysql_error? fwiw tried debugdumpparams , returns this: update `users` set user_active= :user_active, user_activation_hash= :user_activation_hash user_i

how mongodb address sql or query injection? explains how handle query injection bson when using javascript on server. haven't been able track down how/whether mongoose handles query injection though. at point have 2 questions: does mongoose protect against query injection (using bson or other method) if does, there quirks it's implementation developer need aware of? mongoose not protect against query injection unfortunately need perform own injection detection following guidelines link above.
