Can I make an alias for `set -l` in the fish shell? -

i make liberal use of set -l / set --local in fish scripts, considered making alias it. name local seems apt. unfortunately, obvious approach doesn't work: function local set -l $argv end this fails because, of course, variable creates local local function itself. using alias doesn't work, either, since it's (perhaps legacy) shorthand above function. is there way can create local variable in calling scope without doing more complicated local foo 'bar' ? make eval (local foo 'bar') work, sort of defeat purpose. i'm open sort of trickery or hacks make work, if exist. i'm afraid not, local variables local topmost scope, , there's no way wrap set without creating new scope. best can this: function def --no-scope-shadowing set $argv end this creates variable in calling function scope. subtly different local: local scoped block, while above scoped function. still may sufficient use case.

Is it possible to have deployment slots with different service plans in Azure WebApps? -

i've worked lot in past azure cloud services web roles, bit new azure websites/webapps. loved concept of multiple deployment slots define webapps, enables useful cd scenarios. in case, have test->preprod->prod slots defined. good! is possible specify different pricing tiers or number of instances each of environments? seem share pricing tier of service plan. possible define different number of instances each one? well, multiple deployment slots available in standard sku (the highest one): http://azure.microsoft.com/en-us/pricing/details/websites/ so, no. require not possible. you can mitigate not using staged publishing. can instead, have different service plans different web apps. can link each of web apps different branch of repository ( https://azure.microsoft.com/en-us/documentation/articles/web-sites-deploy/ ). when push uat branch - deployment in uat web site. when push relese branch, deployment releas web site , on.

bash - PS1 can't have two "\$"? -

(so, "\$?" gets evaluated 0 , stays 0 .) any thoughts why happening? note: have tried ps1='$(date +"%a %b %e, %t") $? >> ' can else replicate in unix bash? if so/if not, please leave comment. i don't know why bash ignores second \$, try using \d format date: ps1="\[\e[00;34;01m\]\d{%a %b %e,

css - Make HTML Element Expand To Fit Content -

i'm writing web app, predominantly in angularjs using css's flexbox of layout, if matters. i've been going crazy on last few hours trying solve problem i'm stuck on. the problem i'm running follows: there 2 side side div s on page. leftmost div menu must height of document's content or browser window (whichever greater). rightmost div 1 content gets appended dynamically. when program starts, rightmost div less height of browser window (because not have content) application progresses, content gets added such longer browser window. a jsfiddle shows problem can found by clicking here . the html structure of fiddle fixed (containers can added should not removed) tremendous simplification of complex application has same basic structure. additionally, set css heights 100% solely because of reading answer, not because know required make work (i want menu start out full screen minimal content, however). the black div represents menu , yellow div repres

delphi - What are the fundamentals of optionally compiling a library or requiring DLL? -

i write component ability developer either require dll or include unit in app compiles library project, without dll. for example, let's it's called "mylibrary". if include mylibrary in uses clause, default require dll distributed application. on other hand, if unit mylibraryimplementation in uses clause, compile inside app without requiring dll. this component inside package installed ide. i'm not sure terminology this, or how go this. i'm familiar writing dll's, , not looking write full code. what fundamental things need know make optional dll possible? you won't find result satisfying. delphi cannot directly load classes dll. instead, you'll need define class in mylibrary unit. you'll have implement of methods there. you're welcome make methods little more stubs delegate work functions in dll, though. in stub constructor, call dll function allocates data structure , returns handle. in 3 other stub methods, pass hand

java - Possible to get native performance for dynamically compiled code that can be unloaded? -

in .net, seems cannot dynamically compile code call compiled code directly (i.e. w/o "remoting", marshaling, etc) and remove (only) compiled code memory you have decide between 2. (by generating code calling appdomain itself) or 3. (by generating code throw-away appdomain), cannot have both. now i'm curious if possible in java. don't know enough classloaders, seems in java could dynamically compile code throw-away class loader call compiled code (say, through virtual method call predefined interface) directly, w/o marshaling remove references compiled class , throw-away class loader gc take care of removal is assumption valid? yes, can compile / load class code away class loader, call without issue. yes, dynamically code reach 'full performance'. there no difference. however, newly loaded code start in interpreted mode , needs warm before compiled. however, point 3. tricky. 'leaking' throw away class loader easy /

html - Wrong output in my php code in EditRocket -

i created hello.php file in editrocket on mac , wrote simple code <html> <body> <?php echo "hello world!"; ?> </body> </html> but got wrong output <html> <body> hello world!</body> </html> the correct output hello world! only. what doing wrong? your problem - interpreter dumps whole output script design. output hello world! only for internet browsers, html renderers. web browsers can read html files , render them visible or audible web pages. browsers not display html tags , scripts, use them interpret content of page. they parsing html , gives graphical representation. if want print hello world! whole output remove html tags code consist of: <?php echo "hello world!"; ?>

powershell - Only copy certain file types after unzipping -

i have following code unzip many folders in directory tree: new-item e:\files -type directory get-childitem -path e:\snl_insurance\* -recurse -exclude "*.md5" | foreach-object { $file = $_ write-host $file; $destination = "e:\files" $shell = new-object -com shell.application $zip = $shell.namespace($file.fullname) foreach($item in $zip.items()){ if ($item.name -eq ".txt") { $shell.namespace($destination).copyhere($item) } } } without if statement script copies zip files on too, not text files contained beneath. thought check make sure file extension .txt (or *.txt ive tried both) $item.name doesn't seem contain thought did. if have ideas and/or can explain $shell variable here (and $shell.namespace helpful) in advance. edit: responses. found way before saw these answers. here solution found if interested: new-item e:\files -type directory get-childitem -path e:\snl_insurance\in

c# - filtering results with Entity Framework -

another kinda newbie question guess. have ef setup , want select records based on filter. have someclass 4 items (all strings keep things simple, lets call them string1, string2, , on). now, in post send filter in instance of someclass, maybe not properties filled in. might end string1="something", string2="bla" , string4="bla2". string 3 = null. now, how setup query? if try like: var dataset = entities.mydatabase .where(x => x.string1 == someclass.string1 && x.string2 == someclass.string2 && x.string3 == someclass.string3 && x.string4 == someclass.string4) .select(x => new { x.string1, x.string2, x.string3, x.string4}).tolist(); ... no results, because string3=null. checking parameters , see if they're set , create query based on that, there must more elegant that. anyone? thanks! ronald the following return rows someclass.string null or equals x.string . var dataset = entities.mydatabase

html - value javascript function and dom -

i have function 1 window , takes value , passes on dom script , writes output screen on <div> or <p> or <a> , work well. my point change dom element , put value on 1 text input. try call input id on function , write value innerhtml,but nor work well. i not call function on input elements on other dom elements. this code var vect = []; function close(val) { var elem = document.getelementbyid("output"); elem.innerhtml = ""; vect.length = 0; (var in val.multiple) { var d = val.multiple[i]; if (c) { elem.innerhtml += c.print("%a, %y %b %d"); vect[vect.length] = c; } } val.hide(); return true; } thanks if want set value of input element, need use value , not innerhtml . should : elem.value += c.print("%a, %y %b %d");

python - Should I create a new Pool object every time or reuse a single one? -

i'm trying understand best practices python's multiprocessing.pool object. in program use pool.imap frequently. every time start tasks in parallel create new pool object , close after i'm done. i encountered hang number of tasks submitted pool less number of processes. odd occurred in test pipeline had bunch of things run before it. running test standalone did not cause hand. assume has making multiple pools. i'd find resources me understand best practices in using python's multiprocessing. i'm trying understand implications of making several pool objects versus using one. when create pool of worker processes, new processes spawned parent one. fast operation has cost. therefore, long don't have reason, example pool breaks due 1 worker dying unexpectedly, it's better use same pool instance. the reason hang hard tell without inspecting code. might not have clean previous instances (call close()/stop() , call join()). might have sent

java - Does collect operation on Stream close the stream and underlying resources? -

does below code need wrapped in try-with-resources make sure underlying file closed? list<string> rows = files.lines(inputfilepath).collect(collectors.tolist()); as javadoc of overloaded files#lines(path, charset) method states the returned stream encapsulates reader . if timely disposal of file system resources required, try-with-resources construct should used ensure stream's close method invoked after stream operations completed. so yes, wrap stream returned lines in try-with-resources statement. (or close appropriately.)
