c++ - Indexing file names and its content -

-

i write program index file names , content in given directory. if match given regular expression, index them. use regex functions.

i don't know how start this.

i use polymorphic approach:

  1. a class base (virtual), basic information (name, parent directory...).
  2. a class file, child of base, represent file.
  3. a class folder/directoy represent directory.

i thinking using map build trees.

may tell me opinion please?

for filesystem functionality, use boost.filesystem.

for regular expressions, use <regex> c++11, boost.regex otherwise.

any initial(!) trouble might have when installing , learning boost pay off.

for map, use std::map.

in case, not reinvent wheel.

-
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 $row): ?> <div id="<?=$...
