gruntjs - Write file even if output css is empty -

-

i want write empty file destination file empty.

is possible?

the error "destination not written because minified css empty".

i'm using grunt-contrib-cssmin module.

only using grunt-contrib-cssmin, cannot.

a place start when wondering specific piece of open source software: source code — task ~70 lines. the source can see "error" you're getting:

if (min.length === 0) {     return grunt.log.warn('destination not written because minified css empty.'); }

you might want "touching" file. if familiar *nix, you'll know touch create file if doesn't exist , not truncate if does. in grunt (node.js) might want node-touch or grunt-exec.

as gruntfile, you'd need one of following 2 tasks:

module.exports = function (grunt) {     var touch = require('touch');     grunt.initconfig({         'cssmin': {             'combine': {                 'files': { 'path/to/output.css': ['path/to/input_one.css', 'path/to/input_two.css'] }             }         },         'exec': {             'touch': { 'command': 'touch path/to/output.css' }         }     });     grunt.loadnpmtasks('grunt-contrib-cssmin');     grunt.loadnpmtasks('grunt-exec');     grunt.registertask('touch', touch.sync.bind(undefined, 'path/to/output.css'));     grunt.registertask('minifycss1', ['cssmin', 'exec:touch']); // 1     grunt.registertask('minifycss2', ['cssmin', 'touch']);      // 2 };
  1. uses grunt-exec.
  2. uses node-touch.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
