BlueSpace is the name of an interpreter for the Whitespace programming language.
Whitespace is an esoteric programming language that was created by Edwin Brady and Chris Morris and is based at http://compsoc.dur.ac.uk/whitespace/. Its syntax consists entirely of characters that are usually invisible when displayed by a computer: space, horizontal tab and line feed.
This interpreter is written in Python 3 and boasts the following features:
- Interpret Whitespace code
- Compile Whitespace code to Python and optionally execute it
- Optimise the generated Python code
- Accept and translate between Whitespace syntax, as well as:
- A printable syntax, which substitutes space, tab and linefeed with
s,tandn, respectively - An assembly-style syntax (described below)
- A printable syntax, which substitutes space, tab and linefeed with
To run a Whitespace program, simply execute ./bspace.py source.ws; to see other options, use ./bspace.py --help.
Each line of the source must match one of the following forms, where number is any decimal integer and label is any string of s and t characters with an optional trailing n. Each line maps to a single Whitespace instruction. A # begins a comment; it and any subsequent characters on the same line are ignored.
