javascript - Grunt-contrib-copy: variables within the rename function -


i have following copy task in gruntfile.js

copy: {         css: {             expand: true,                   cwd: 'min/css',               src: 'theme_<%= props.majorversion %>.<%= props.minorversion %>.min.css',                       dest: 'dest/dir/',             rename: function(dest, src) {                 return dest + src.replace('_<%= props.majorversion %>.<%= props.minorversion %>','');             }         }     }

currently, file copied once copied, i'd remove version numbers make part of file name.

they defined earlier in gruntfile , working expected until rename function.

current file_1.123.css , i'd end file.css.

i've tried various different ways pass variables rename function without success.

thanks.

try substring instead:

rename: function(dest, src) {            return dest + src.substring(0, src.indexof('_')) + '.css';         }

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.
