What Metaprogramming is…

Metaprogramming is coding some programs that generates new code segments to be executed while execution time. So why it is a need.

  • We determined which problems were best solved with a code-generating program, including:
    • Programs that need to pre-generate data tables
    • Programs that have a lot of boilerplate code that cannot be abstracted into functions
    • Programs using techniques that are overly verbose in the language you are writing them in
  • We then looked at several metaprogramming systems and examples of their use, including:
    • Generic textual-substitution systems
    • Domain-specific program and function generators
  • We then examined a specific instance of table-building
  • We then wrote a code-generating program to build static tables in C
  • Finally, we introduced Scheme and saw how it is able to tackle the issues we faced in the C language using constructs that were part of the Scheme language itself

I got familiar to this idea from the talk of a ruby programmer and here is the link to the video of that talk about how to metaprogramming in ruby.
