Misc-Stack-Scripts

This contains many random stack based programs I’ve created over the years.

Factor Specific

• I like to symlink the Factor directory to “factor/work”, so that scaffold creates the work for me. Further it prevents factor from failing half way through dumping an image.
  • This is unnecessary if one uses the .factor-roots and calls scaffold-vocab when creating a new vocabulary!

Interesting Projects

• The most interesting programs are in the Factor sub-directory. And not all of them are interesting.
  • Projects
    • allocators
      • Contains code dealing with various memory allocation strategies.
      • Shows off how Factor deals with alien functions and how to communicate between factor and c efficiently.
    • misc/padding
      • This one simply shows off padding in C structus easily via Factor. Inspecting the values created in the repl is nice.
    • tax
      • This is just a little program I’ve been using that does tax calculations for the Taiwanese tax system. I also use this to calculate monthly expenses, probably only of interest to me.
    • compiling-lisp/unary
      • This is an unfinished project, however it was my first attempt at using the alien function interface in Factor. With that said, it does showcase Factor’s assembler and marking regions as executable
  • Unfinished and not of interest
    • finger-tree
      • Currently this does nothing, but does showcase the match and VARIANT: capabilities of factor
    • queue
      • More VARIANT:. Ι believe Ι was interested in implementing purely functional data structures at this time.
    • first
      • This is my very first factor file and code. It is akin to watching a child learn how to walk for the first time, however the quicksort function is cool.
      • In the future I’ll create a playground similar to smalltalk for my various throwaway code.
    • michelson
      • Ι wanted to make a faster michelson compliant code in Factor, would be nicer than using the normal interpreter in OCaml.
