Abdulaziz Ghuloum 71640d11bf Fixed a problem with forward references in the repl which used to
get a location different from the one assigned when the variable is
defined.
2008-05-15 06:40:07 -07:00
Abdulaziz Ghuloum f8b0e949d9 - syntax-case now raises a syntax violation when _ appears in the
literals
- syntax-rules points to the invalid literal when raising an
  exception.

Abdulaziz Ghuloum 5c21f9995e source annotations for r6rs-script and r6rs-libraries are now in

Abdulaziz Ghuloum 3f9b567a5b with-syntax now gives more informative error messages:
> (with-syntax ([(x y) #'(a 1)] [(q) #'(a b c)]) 12)
Unhandled exception
 Condition components:
   1. &assertion
   2. &who: with-syntax
   3. &message: "pattern does not match value"
   4. &irritants: ((q) #<syntax (a b c)>)

instead of the previous behavior:

> (with-syntax ([(x y) #'(a 1)] [(q) #'(a b c)]) 12)
Unhandled exception
 Condition components:
    1. &message: "invalid syntax"
    2. &syntax:
        form: ((a 1) (a b c))
        subform: #f

Abdulaziz Ghuloum b56b0fbd85 fixed a problem causing free-id=? to intern unbound identifiers
into the interaction environment.

Abdulaziz Ghuloum d49aed209a Added (interaction-environment). 2008-05-01 06:02:36 -04:00
Abdulaziz Ghuloum e7386cd7d7 Major changes to the interactive repl:
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
  top-level.

Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously.  In
  particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define.  Once
  something is defined at the top-level, a specific location for it
  is created, and all definitions, references, and set!s to that
  variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
  location for that variable.

Let's see how this goes.

Abdulaziz Ghuloum 89def78c3c Fixed the definition of identifier? and id? in expander so that only
top-make-wrapped (possibly annotated) symbols are identifiers.  It
used to be that symbols were considered identifiers by the previous
definition.
2008-04-28 14:01:49 -04:00
Abdulaziz Ghuloum 3ce6d037e4 Fixed a bug in module imports where some marks were missing in action.
(Note from Kent, extracted from chez scheme release notes, follows)

This always worked:

(let ()
  (define-syntax from
    (syntax-rules ()
      [(_ m v) (let () (import m) v)]))
  (module a (x) (define x 'x-of-a))
  (from a x))

Didn't work before this change:

(let ()
  (define-syntax x-from-a
    (syntax-rules ()
      [(_) (let () (import a) x)]))
  (module a (x) (define x 'x-of-a))
  (x-from-a))

Abdulaziz Ghuloum f4fb08adba Added an experimental macro expansion stack trace that looks like:
Unhandled exception:
 Condition components:
    1. &who: let
    2. &message: "not an identifier"
    3. &syntax:
        form: (let ((12 a)) (printf "a=~s\n" a)) 
        subform: 12
    4. &trace: #<syntax (let ((12 a)) (printf "a=~s\n" a))>
    5. &trace: #<syntax (right 12 a (printf "a=~s\n" a))> 
    6. &trace: #<syntax (wrong a 12 (printf "a=~s\n" a)) [byte 216 of test.ss]>


For a file containing:

(define-syntax right
  (syntax-rules ()
    [(_ a b c) (let ([a b]) c)]))
 
(define-syntax wrong
  (syntax-rules ()
    [(_ a b c) (right b a c)]))

(right x 17 (wrong a 12 (printf "a=~s\n" a)))
