The scribble/eval library provides utilities for evaluating code at document-build time and incorporating the results in the document, especially to show example uses of defined procedures and syntax.
Here is an example where the OP was:
trying to figure out a way to insert some text in between Scheme definitions: that is, have some definitions (@schemeblock or equivalent), with their explanations (text mode), and then an interaction, like @interaction, except that it should be aware of the preceeding definitions.
Here is the solution:
#lang scribble/manual @(require scribble/eval) @(define ex-eval (make-base-eval)) First, we define @scheme[x]: @interaction[ #:eval ex-eval (define x 1) ] Next, we use it: @interaction[ #:eval ex-eval x ] @(close-eval ex-eval)
