C IDEs: preprocessor-aware code navigation -

-

background

i spend lot of time navigating , editing convoluted scientific c codes. contain hundreds of optional features switched on , off preprocessor directives. makes impossible @ glance whether current block of code activated in current setup or not. code not every feature smudged on place , done using global variables.

question

is there ide can handle preprocessor directives folding/shading inactive code?

i imagine 1 can maintain project config of used flags , work not being bothered inactive branches of logic.

looking @ similar question seems eclipse cdt has functionality need , the other question tells can set ifdefs.

emacs has similar in form of hide-ifdef-mode.

but can try use ide-agnostic solution running code through unifdef , working result. if need read code, it's perfect solution. if need make changes, things become bit more complicated, can use git manage changes, like:

  • import whole code base git
  • run through unifdef
  • commit result, that's basis patches
  • work code base in whatever ide/editor prefer, commiting changes usual
  • if there need produce patches original code base, checkout original import commit , cherry-pick (or rebase) patches branch (of course there chance conflict, should quite easy resolve know intended change code patch , need adjust ifdefs)
  • if there need update code base, start original import, apply update, commit that, run through unifdef, commit , rebase changes on top of that

of course, whether approach work or not depends on particular code base , you're going it, can useful in scenarios.

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
