Hi everyone,
I have been testing literate programming in Racket recently (#lang
scribble/lp2), and found it overall quite nice - until I wanted to
include tests in the usual way, by creating a submodule "test":
==================================================
#lang scribble/lp2
@chunk[<drop>
(define (drop t)
(* 1/2 9.8 t t))]
@chunk[<test-drop>
(check-= (drop 0) 0 ε)
(check-= (drop 10) 490 ε)]
@chunk[<to-energy>
(define (to-energy m)
(* m (expt 299792458.0 2)))]
@chunk[<test-to-energy>
(check-= (to-energy 0) 0 ε)
(check-= (to-energy 1) 9e+16 1e+15)]
@chunk[<*>
(provide drop to-energy)
<drop>
<to-energy>
(module* test #f
(require rackunit)
(define ε 1e-10)
<test-drop>
<test-to-energy>)]
==================================================
This is a straightforward conversion of a submodule example from the
Racket guide to #lang scribble/lp2. But it doesn't work, because the
bindings drop and to-energy are not visible inside the test submodule.
Given that scribble uses submodules itself, I am not sure if this is
supposed to work. What I am more interested in is finding a workaround.
Is there some way to combine literate programming and testing using
"raco test"?
Konrad.
