Tiny stack-based language implementation (61 sloc, Python)
- WalterGR 5y agoThe only examples are in the source. [ dup * ] is square [ dup 2 < [ drop 1 ] [ dup 1 - fact * ] ifelse ] is fact 4 square . 5 fact .
- richard_shelton 5y agoIf you are familiar with Forth, Postscript, or Joy you should have no problems with programming in Fortik :) Still, the idea of Fortik is to encourage students to learn how simple interpreters work and to extend the language.
- WalterGR 5y agoIs the first assignment to reverse-engineer the language spec from the interpreter?
- richard_shelton 5y agoBasically, yes, so I tried to make a simple implementation as possible. And I'm taking into account that students are already familiar with postfix notation and stack data structure. Of course, I use additional sources (like the popular Crafting Interpreters book) in the teaching process.
