In the late 1960s and continuing through the 1970s there was a flurry of research activity into the theory of compilation in which many of the algorithms, patterns, and techniques used to implement compilers and interpreters that we use today were deve

In the process of turning text into executable programs two of the early transformations that take place are converting said text into a stream of tokens - commonly called "lexing", and transforming this token stream into abstract syntax tree (AST). Th

In my previous post I went over one possible scheme for an Object structure suitable for implementing dynamic typing in an interpreter. Tha

Programs rarely exist in isolation. With a few exceptions, a program requires a supporting environment within which to run. For a compiled language, this can be handled by the operating system or in more extreme cases like micr
