Abdulaziz Ghuloum 53905b9eea Changes from Derick Eddington supporting file system info:
- Added file-regular?, file-directory?, file-symbolic-link?,
  directory-list, make-directory, delete-directory, change-mode, 
  and make-symbolic-link.

- Bug fix in ikrt_open_input_fd and ikrt_open_output_fd which
  considered a 0 FD as an error.

- Bug fix in ikrt_getcwd about len+1.

- Bug fix of &i/o-file-protection which didn't have &i/o-filename as
  its parent.

- There is a new src/ikarus-errno.c file.  

- Made tcp-connect and friends tell when they "failed to resolve
  host name or connect".

- To support the uses of &i/o-filename subtypes, I modified
  print-condition so it will cleanly print the parents' fields of a
  condition;

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
2008-05-03 06:23:35 -04:00

2008-05-01 15:04:43 -04:00
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.
2008-05-01 04:21:07 -04:00
Abdulaziz Ghuloum 1389f239fe Added process-nonblocking which is like process but returns
nonblocking ports.
2008-04-30 22:55:59 -04:00
Abdulaziz Ghuloum f69e82e6c5 Added with-output-to-port:
> (let-values ([(p e) (open-string-output-port)])
    (with-output-to-port p (lambda () (printf "Hello\n")))
    (e))
"Hello\n"
2008-04-29 00:20:29 -04:00
Abdulaziz Ghuloum d8cd4f0acf Added engine-handler parameter and a ($swap-engine-counter! <neg-fx>)

#\xHHHH  "\xHHHH;" and foo\xHHHH;bar sequences.
2008-04-28 15:01:45 -04:00
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))
2008-04-19 17:55:30 -04:00
Abdulaziz Ghuloum 66d085713f Made interrupted conditions &serious so that you can interrupt R6RS
scripts.
2008-04-19 16:55:40 -04:00
Abdulaziz Ghuloum 177f6b84a7 Fixed a reader bug that causes '#!eof not to read properly.
Used to be:
> '#!eof
Unhandled exception
 Condition components:
  1. &lexical
  2. &message: "invalid eof after quote read macro"
  3. &lexical-position:
      file-name: *stdin*
      character: 7

Now:
> '#!eof
#!eof
