SingleScheme

SingleScheme is a programming language designed to simplify the process of writing single-pass compilers. It is particularly useful for educational purposes and for creating small, efficient compilers. The language was developed by Robert Griesemer and is inspired by the principles of simplicity and minimalism.

SingleScheme is based on a small set of core concepts, including a single data type, a single control structure, and a minimal set of built-in functions. This simplicity makes it easier to understand and implement a compiler for the language. The language's syntax is designed to be straightforward and easy to parse, which is essential for a single-pass compiler.

One of the key features of SingleScheme is its use of a single data type, which is a 64-bit integer. This simplifies the implementation of the compiler's data structures and reduces the complexity of type checking. The language also uses a single control structure, which is a conditional statement that allows for branching based on the value of an expression.

SingleScheme's minimal set of built-in functions includes basic arithmetic operations, input/output functions, and a few other utility functions. This simplicity makes it easier to implement the compiler's code generation phase and reduces the overall complexity of the compiler.

Overall, SingleScheme is a useful tool for learning about compiler construction and for creating small, efficient compilers. Its simplicity and minimalism make it an ideal choice for educational purposes and for creating compilers for small, specialized languages.
