gulp task starts but does not end -


i have next files structure:

src/     themes/         default/             1.png             2.png         onemoretheme/             3.png             4.png dist     themes/         default/         onemoretheme/

and next gulpfile:

  'use strict';    var gulp = require('gulp'),     _ = require('lodash'),     plugins = require('gulp-load-plugins')();    gulp.task('images', function () {     var streams = {},       themes = [         'default',         'onemoretheme'       ];      streams.themesimages = [];      _.foreach(themes, function(theme) {       streams.themesimages.push(gulp.src('src/themes/' + theme + '/*.*')       .pipe(gulp.dest('dist/themes/' + theme + '/')));     });      streams.allthemeimages = plugins.merge(streams.themesimages);      return streams.allthemeimages;   });

i can not understand 2 things: 1) why see in console next text when task "images" starts:

"d:\home\projects\storybook>gulp images [15:05:23] using gulpfile d:\home\projects\storybook\gulpfile.js [15:05:23] starting 'images'..."

but when task finished not see next text:

"[12:13:56] finished 'images' after 5.72 s"

why not text? streams merge , return merged stream have synchronous task. maybe wrong?

2) if add 1 code line privous code:

streams.allthemeimages = plugins.merge(streams.themesimages); return streams.allthemeimages.pipe(gulp.dest('temp/')); // here new code line

i expect in temp folder i'll have next images: temp/ 1.png 2.png 3.png 4.png because merged streams, first 1 contains 1.png , 2.png images , second 1 contains 3.png , 4.png. in reality next files: temp/ 1.png 2.png wrong?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
