javascript - Using RequireJS in NodeJS with CoffeeScript without transpilation -


probably pretty straightforward question, still haven't found feasible solution far. able run server purely coffee files , mocha tests able work coffee files. requirejs still looking *.js files :/ not feeling transpiling satisfy requirejs.

probably easier way use nodejs extensions, since it's deprecated, it's not way. thinking solution this:

requirejs.config({     noderequire: require,     compilers: [         {             extensions: ['.coffee','.litcoffee','.coffee.md']             compiler: require('coffee-script').compile         }     ] })

it file these extensions , when found, compile it. otherwise keep default behavior. sure, means performance issues when looking these files, since it's meant development only, don't see big problem.

unfortunately it's hard me understand how requirejs works under hood. otherwise have tried work out solution this.

is there other solution missing ?

solved

after of have decided quite opposite approach. use require browser side too, don't need change server code.

related (my question): how can connect-assets recompile coffee files when change?

this possible connect-assets. layer sits between request , assets , compiles them on-demand. tried going route , found lot of work -- ran situations connect wouldn't compile coffee js correctly. or something, doing wrong since new node @ time. wasn't comfortable relying on asset layer in production.

in end settled on serving js files , building them when changed using grunt, grunt-contrib-watch , grunt-contrib-coffee. advantage there if run error on particular line of js, can open file , @ line failed. if you're new coffeescript occasionaly wrong , end wacky javascript. it's helpful able pull js file , see it.

there lot of similar tasks need automated in building web app, grunt useful tool in many situations. recommendation.

here's sample of grunt setup: 

  # project configuration.   grunt.initconfig     watch:       coffee:         files: ['app/assets/src/coffee/**/*.coffee', 'app/assets/src/coffee/*.coffee', 'app/webserver.coffee']         tasks: ['coffee:dev', 'replace', 'test']

with setup (not of here) can transpile coffee files, run tests, perform bit of text manipulation on files , have clean , ready go web app inside of 2 seconds.

require takes bit head around in summary looks locally (client side) see if has library , if doesn't gets server. won't transpiling , seems bit out of 'mission parameters' if will. require parts guy @ auto parts shop: checks see if tool available @ front counter; yes, hands you; no, goes , gets it.

if want use coffee in node without transpiling it, try require-cs.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
