An interpreter for the Shakespeare Programming Language.

Project Description

An interpreter for the Shakespeare Programming Language, implemented in Python.

What is the Shakespeare Programming Language?

The Shakespeare Programming Language (SPL) is a programming language with source code that looks like Shakespeare’s plays. The language is Turing complete, so theoretically just as powerful as any other language. It’s a lot of fun to write but not practical for any large projects. More info can be found on Wikipedia.

Note: Shakespeare’s actual plays are not valid SPL. SPL does not aim to provide backwards compatibility with legacy code written ~400 years ago.

What is this project?

This is an interpreter I wrote for SPL. It’s written in Python. The aim is to help programmers better understand how their SPL code is executing, with features like a console and debugging. All previous implementations of SPL were source-to-source-compilers, which makes an already confusing language even harder to follow.

What state is this project in?

I haven’t written any tests yet, but it will probably run any valid SPL program. The console and debugger are both working.

Installation

pip install shakespearelang
# Or however else you install things. You do you.

Instructions

CLI

shakespeare run my-program.spl
shakespeare debug my-program.spl
shakespeare console # or just "shakespeare" unadorned

Console

In the console, you’ll essentially write an SPL program/play line-by-line, defining your characters first.

Input to the console can be any of these:

  • Entrances, exits, and spoken lines as they would normally appear in a play/program.
  • Sentence(s) spoken by the last character who was speaking. For example, if the previous line was Juliet: You are a fat pig., the sentences Remember thyself! You are a fat fat pig. could be tacked onto the previous line.
  • Expressions (standalone values without assignment), spoken implicitly by the last speaking character or with an explicit character: Juliet: The difference between thyself and a fat pig. These cannot end with periods.
  • A character’s name, which displays that character’s stack and current value.
  • stage, which displays which characters are on and off stage.
  • exit or quit, which will leave the console.

Debugging

Debugging and running are identical for many programs. In order to utilize the debugging feature, you’ll need to place a breakpoint somewhere in your SPL code using the following stage direction:

[A pause]

When the debugger hits this stage direction, it will pause execution of the play/program and enter a REPL. This is just like the standalone console, except you can use the next command to step forward, and the continue command to exit the REPL and continue running the program/play.
