Usage
See: https://github.com/p0nce/scheme-d/blob/master/examples/repl/repl.d
Supported
A small part of R6RS is supported:
- Types: double, string, bool, list, symbol, and closure (Scheme functions or D callbacks)
- pre-defined operations: https://github.com/p0nce/scheme-d/blob/master/source/schemed/environment.d#L51
- special forms: https://github.com/p0nce/scheme-d/blob/master/source/schemed/eval.d#L47
Unsupported features
A large part of R6RS is unsupported:
- vectors (list is already implemented with D slices)
- Scheme literals syntax for float, string or chars
- quasi-quoting
- Scheme numerical tower. Only double is provided
- char type
- \x escape sequence in strings
Bugs
- symbols have too lax a grammar, should respect Extended alphabetic characters
