WebThe book also demonstrates that systematic transformations, say, store-passing style or continuation-passing style, can eliminate certain constructs from the language in which the interpreter is formulated. The second part of the book is dedicated to a systematic translation of the interpreter into register machines. WebOct 8, 2024 · Quoting the Scheme examples (with their explanatory texts) from Wikipedia's Continuation-passing style article, but Scheme examples are translated to Haskell, and …

WebGuile’s CPS language is composed of continuations. A continuation is a labelled program point. If you are used to traditional compilers, think of a continuation as a trivial basic block. A program is a “soup” of continuations, represented as a map from labels to continuations. Like basic blocks, each continuation belongs to only one function. WebIn Scheme, the current continuation can be reified as a function by using the built-in function call-with-current-continuation, or call/cc for short. (call/cc expr) does the following: Captures the current continuation. Constructs a function C that takes one argument, and applies the current continuation with that argument value. ontario which state
[Scheme] Continuation Passing Style : compsci - Reddit
WebThis continuation is a function value representing the actions that must happen after the function 'returns'. The stack becomes obsolete in continuation-passing style ― when a function calls another function, that is the last thing it does. Instead of waiting for the called function to return, it puts any work it wants to do afterwards into a ... WebContinuation-passing style. make all recursive calls tail calls by packaging up any work remaining after the would be recursive call into an explicit continuation and passing it to … WebThis can be a valuable technique in Scheme programming regardless of whether or not we are defining an interpreter. The added benefit of writing an interpreter in continuation passing style is that it becomes easy to add all sorts of flow of control primitives to the language being implemented by the interpreter. ionic screening in bulk and under confinement
