The Programming Languages Zoo

A potpourri of programming languages

How to contribute

The source code adheres to standards that keep it uniform and demonstrate (what we beleive to be) good programming practice. We kindly ask that all contributions to the repository follow the established pattern, and follow these guidelines:

  1. The name of the language should also be a valid OCaml module name.
  2. The language source code for language lang resides in src/lang.
  3. If the language is an extension of lang with feature X, call it lang_X.
  4. Language lang should have a file src/lang/example.lang which shows how it is used.
  5. Language lang should have a file src/lang/README.markdown which explains briefly what the language is about. You can also put examples in this file, but note that the web page will already link to src/lang/example.lang so there is no point in just copying that to the README.markdown file.
  6. Instead of making one language with many features, make several languages each demonstrating a feature.
  7. Use interfaces .mli files and comment all entries in the interface using the ocamldoc format (** ... *).
  8. The main program should use the Zoo.Main functor:

     module MyLanguage = Zoo.Main(struct .... end) ;;
     MyLanguage.main() ;;

    This will give your language line-editing capabilities (if rlwrap is installed) and a uniform user interface.

  9. Do not use open to open modules, there are better solutions (the best one is to just not look for any shortcuts).

Remember: these are guidelines that can be broken for a good enough reason.
