ruby - What languages support "dynamic" metaprogramming? -


in metaprogramming ruby, author states few languages, including ruby, can manipulate @ runtime. other languages besides ruby can support type of metaprogramming?

the specific quote i'm referring in introduction on page xix:

in book, i'll stick different meaning of metaprogramming, focusing on code manipulates @ runtime. few languages can effectively, , ruby 1 of them. can think of dynamic metaprogramming distinguish static metaprogramming of code generators , compilers.

most languages days moving towards providing kind of functionality, it's not "clean" it's in ruby. these languages have lot of capabilities (reference):

  • actionscript
  • basic
  • beanshell[3]
  • clojure
  • coldfusion
  • common lisp , other lisps
  • groovy[4]
  • e programming language
  • javascript
  • vbscript
  • matlab / octave
  • lua
  • objective-c
  • perl
  • php
  • powershell
  • python
  • ruby
  • smalltalk
  • tcl

other languages such java , c# (reference) have ways of inspecting , creating code @ run time, it's not "natural" in languages, , feels lot hack.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
