BSL (How to Design Programs): how to import code from a separate file into definitions area?

Question

I\'m having an issue with BSL. I want to divide my code into separate auxiliary files and use

(require \"auxiliary-function.rkt\") 

at the beg

Answer 1

Note that if you're doing this for a course this strategy might not be accepted for a submission.

What I have done for some of my own projects is a pattern like this:

Have one file written in plain Racket, called "provide.rkt", like this:

; provide.rkt
#lang racket
(provide provide all-defined-out)

Then you can use this to either provide specific functions or provide all definitions from a file.

For providing specific functions

In your "library" BSL file, you can require provide into it like this, and use that to provide the specific function(s) you want:

; .rkt
; written in BSL
(require "provide.rkt")

(provide )

(define ( ....) ....)

And finally, in your "main" BSL file, you can require the library like this:

; written in BSL
(require ".rkt")

( ....)

For providing all definitions from a file

In your "library" BSL file, you can require provide into it and use that to provide everything:

; .rkt
; written in BSL
(require "provide.rkt")

(provide (all-defined-out))

(define ( ....) ....)

(define ( ....) ....)

...

Then in your "main" BSL file, you can require the library and get all of the definitions:

; written in BSL
(require ".rkt")

( ....)

( ....)
