Abdulaziz Ghuloum 4df1dcb25a attempting to reference/modify unexportable bindings was crashing
the expander instead of raising a proper error.  fixed.

Abdulaziz Ghuloum b586d2e21a some asserion violations in the reader are converted to &lexicals so
that the repl displays them properly.  E.g., 
(read (open-string-input-port "#!r6rs |foo|")) shows an &assertion,
but typing #!r6rs |foo| at the repl causes the repl to reset without
a message.

Abdulaziz Ghuloum ac3581286f Ikarus now supports PLT's Scribble syntax!
- The only thing unsupported is the transposition of punctuations,
  e.g., @`foo{bar} => `@foo{bar}.
2009-07-29 19:07:03 +03:00
Abdulaziz Ghuloum cdea4e0942 added define-fluid-syntax and fixed fluid-let-syntax. 2009-07-28 22:12:48 +03:00
Abdulaziz Ghuloum 7961405db7 input ports now support "input-port-column-number" and
"input-port-row-number".  These currently work for string ports,
latin-1 ports, and utf-8 ports as long as only ascii chars are 
read.

Abdulaziz Ghuloum 9e764c76b4 - eqv? and equal? now guarantee #t when given two NaNs (unspecified
by R6RS).
2009-07-20 10:01:05 +03:00
Abdulaziz Ghuloum fe88c7bd0d fixed incorrect setting of IKARUS_LIBRARY_PATH. 2009-07-06 13:20:09 +03:00
Abdulaziz Ghuloum acbd00c356 fixed a bug in expanding macros in definition context where the
scope would get messed up when the macro call appears inside
let/letrec-syntax.  Basically, in the following example,

(let-syntax ([id-macro (syntax-rules () [(_ x) x])])
  (let () 
    (define (foo) (display "not ok\n")) 
    (let-syntax ([foo (syntax-rules () [(_) (display "ok\n")])])
      (id-macro (foo)))))

the call to (id-macro) would make (foo) refer to the foo in the
internal-definition context (the not ok one) instead of the
let-syntax one.

On the plus side, macro expansion is now half a second faster!

Abdulaziz Ghuloum b324709e86 - ratnum->flonum now handles more numbers, though it's now slower

2009-06-26 11:15:02 +03:00
Abdulaziz Ghuloum f495665f7d changed "condition" to "exception" in debugger output. 2009-06-26 11:05:40 +03:00
Abdulaziz Ghuloum d2cc4c65a3 put-string now takes the required optional arguments (same as
put-bytevector)
2009-06-26 10:52:56 +03:00
Abdulaziz Ghuloum 5e02972e7f enabled debug-scc flag for debugging the scc pass of the compiler
(not useful for casual users)
2009-06-14 12:06:48 +03:00
Abdulaziz Ghuloum 2a0e53dcb0 minor work on command-line:
- no dependence on ikarus
  - split tests from main library
2009-06-02 01:12:07 +03:00
Abdulaziz Ghuloum 471921fcc7 NEW: ikarus --r6rs-repl <script-name>
runs the script according to the R6RS semantics, then starts a
  repl in an interaction environment made of everything visible
  (imported and defined) in the script.

  Use cases include:
  * debugging a script.
  * starting ikarus in some predefined environment, e.g., 
       $ ikarus --r6rs-repl rnrs.ss
    where rnrs.ss contains (import (rnrs))

  Also, interaction-environment is made a parameter with an initial
  value set prior to entering the repl.

Abdulaziz Ghuloum 5f4151a2e9 moved port position into cookie instead of being its own vector. 2009-05-30 13:34:18 +03:00
Abdulaziz Ghuloum 3099d1d629 moved output strings, file descriptors, and port mode into a port "cookie" 2009-05-30 13:18:43 +03:00
Abdulaziz Ghuloum eec9453fc7 - if IKARUS_LIBRARY_PATH is set, "." is no longer added to
library-path, so, whereever you set it, you should decide whether
  to include "." or exclude it.
  ["$prefix/lib/ikarus" is still added to the path so that multiple
  versions of ikarus can exist and each uses its own sources dir
  without interference]

- some cleanup in compiler to use the new include library instead of 
  "ikarus.include-src.ss" which is no longer needed.
2009-05-30 10:46:45 +03:00
Abdulaziz Ghuloum ac0e583310 - include now resolves relative includes (where file name does not
start with "/") according to library-path.  Absolute paths are not
  resolved.
2009-05-30 09:47:56 +03:00
Abdulaziz Ghuloum f13876d385 - removed include and include-into from (ikarus) library
- moved include and include/lexical-context to their own 
  (ikarus include) library (source only, not in boot image).
2009-05-30 08:14:09 +03:00
Abdulaziz Ghuloum 2653cedee1 expand changed:
- it now takes an optional environment (it was required)
  - it no longer returns a second value (list of libraries)
  - it's output is "pretty".

the old expand is now called core-expand.

Abdulaziz Ghuloum 83d8f051fe fixed minor bug in cogen of vector? 2009-05-28 14:04:19 +03:00
Abdulaziz Ghuloum 1dd8e71a2c RC files:
Summary:
  By default, ikarus now executes the file $HOME/.ikarusrc (which
  must be an R6RS script) (if it exists) before startup.

Details:
  
There is a default behavior for RC files which can be overriden by
command-line options.

Default RC files location:
  1. If the command-line argument --no-rcfile is set, the set of RC
     files is empty.
  2. Otherwise, if there is at least one --rcfile <filename> 
     command-line argument, the specified files are used as the set
     of RC files.  (--rcfile and --no-rcfile are mutually exclusive)
  3. Otherwise, if the environment variable IKARUS_RC_FILES is set,
     the colon-separated list of files are used as the RC files.
  4. Otherwise, if the file $HOME/.ikarusrc exists, only it is used.
  5. Otherwise, the set is empty.

The startup sequence is now:
  1. Setup the library path.
  2. Execute all RC files.
  3. Set command-line options (e.g., -O2, --debug, etc.).
  4. Set command-line-arguments.
  5. Proceed with normal operation (start repl, run an r6rs script,
     compile dependencies, etc.).

Abdulaziz Ghuloum 24ece86772 - Added stale-when:
syntax:  (stale-when guard-expr e* ...)   ;; in definition context
            (stale-when guard-expr e e* ...) ;; in expression context

   semantics:
     When a stale-when form is encountered while expanding any code
     (expressions, macros, macros in macros, etc.) in a library
     body, the guard-expr is expanded (but not evaluated) and
     serialized along with the library.  When the library is later
     reloaded from fasl and before it is installed, the guard-expr
     is evaluated.  If guard-expr returns true, the fasl content is
     ignored and the library is recompiled afresh from source.

Abdulaziz Ghuloum f759815a8c - Ikarus now recognizes IKARUS_FASL_DIRECTORY (and the corresponding
fasl-directory parameter) that works as follows:
  - if IKARUS_FASL_DIRECTORY is set to "", no fasl files are produced.
  - if IKARUS_FASL_DIRECTORY is set to something other than "", the
    string is used as a directory in which fasl files are placed.
  - if IKARUS_FASL_DIRECTORY is unset, the directory 
    $HOME/.ikarus/precompiled is used for fasl output.
  - library file names are cannonicalized using file-real-path.
  - the fasl file (if produced) is the result of
     (string-append (fasl-directory) (file-real-path filename) ext)
    where ext is either ".ikarus-32bit-fasl" or ".ikarus-64bit-fasl".

- The old behavior (placing the fasl files in the same place as the
  library files) can be achieved by setting IKARUS_FASL_DIRECTORY='/'.

Abdulaziz Ghuloum a050e28633 new boot files 2009-05-26 13:00:03 +03:00
Abdulaziz Ghuloum 1d9a26cefd - changed fasl extension to be ".ikarus-32bit-fasl"/".ikarus-64bit-fasl"
(depending on the target processor) instead of just ".ikarus-fasl".
2009-05-26 12:04:55 +03:00
Abdulaziz Ghuloum 5e5cbfe18b - Added make-directory* (like make-directory, but builds the whole
directory structure recursively) 
- Added split-file-name (takes a string, returns two values: the
  substring before the final "/" and the string after it).
- Fixed a minor bug in file-directory?, file-exists?, etc. that were
  failing on OS X if part of the path given was not a directory.
  E.g., if /tmp/foo is a regular file, (file-directory? "/tmp/foo/bar")
  was raising an exception instead of returning #f.
2009-05-26 01:14:11 +03:00
Abdulaziz Ghuloum 9cb0945f1f - Added file-real-path which is identical to realpath(3). 2009-05-25 22:19:43 +03:00
Abdulaziz Ghuloum 27112fec4e fixed bug that produced an incorrect assertion violation for
(put-bytevector! port bv i j) where i = (bytevector-length bv).
Thanks to Andreas Rottmann.
2009-05-24 12:49:53 +03:00
Abdulaziz Ghuloum ec76547da0 - procedures made with defun-style definitions now have proper
source annotation (pointing to the identifier that's the name of
  the procedure, instead of the define keyword itself).
