(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='/'.
2009-05-26 13:39:32 +03:00
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).
2009-05-24 12:34:39 +03:00
Abdulaziz Ghuloum f3b071548d - improved debugger speed when debug-calling a primitive operation.
Ack now runs only 80 times slower in debug mode (down from 360
  times), and bootstrapping is now done in 170 seconds instead of
  500 (nondebug time is still less than 8 seconds).
2009-05-24 11:59:18 +03:00
Abdulaziz Ghuloum ae136274ed - the source-level optimizer now optimizes (inlining,
constant-folding, etc.) across debug-calls.
2009-05-21 18:43:28 +03:00
Abdulaziz Ghuloum b35f5a9e1d - trace-lambda and debug-call now interact properly and do not lose
tail calls.
2009-05-21 11:47:24 +03:00
Abdulaziz Ghuloum 8ef5eaeca2 - better error message for using make-c-callout and make-c-callback
when ffi support is not enabled.
2009-05-20 09:58:03 +03:00
Abdulaziz Ghuloum beb3845e9d - modified the ikarus debugger to use the same continuation frame
structure as the one the tracer uses.
2009-05-19 19:46:23 +03:00
Abdulaziz Ghuloum 1781866f1c - small change to how the tracer works internally and how it keeps
track of continuation frames and trace depths.
2009-05-19 13:16:59 +03:00
Abdulaziz Ghuloum a489f169ee - added trace-let 2009-05-18 11:14:17 +03:00
Abdulaziz Ghuloum ff25a484fb - Added -d (--debug) flag that enables debugging at the repl, r6rs
scripts, and compiling dependencies.  This is the first stab at
  the debugger.  It's SLOW!
2009-05-18 02:08:02 +03:00
Abdulaziz Ghuloum dbf0b07f13 - added lab/ikarus.debugger.ss which is more usable (faster) than
the interpreter and is closer to how the compiler would handle
  debugging calls.
2009-05-17 12:50:16 +03:00
Abdulaziz Ghuloum 2929379460 - debugging in interpreter is changed to use continuation frames
dynamically instead of performing context-sensitive transformation
  to determine tail/nontail calls.
- interpreter now has options to reraise, continue, or quit.
2009-05-17 06:51:09 +03:00
Abdulaziz Ghuloum 391e2fa87b - ikarus interpreter improvements:
- shows prettier traces (frame and reduction numbers, chopped
    strings, etc)
  - can be resumed after being suspended with ^C
2009-05-16 09:57:37 +03:00
Abdulaziz Ghuloum fda2817a73 - ikarus interpreter (in lab directory) is now capable of
bootstrapping ikarus
2009-05-14 10:18:45 +03:00
Abdulaziz Ghuloum 3207e14fca - psyntax now produces
`(annotated-call ,annotation ,rator ,rands ...)
   form for cases when there is an annotation attached to the procedure
   call.  The compiler just stripps it out and makes no use of it.
2009-05-14 09:52:05 +03:00
Abdulaziz Ghuloum 39c8e8e23f removed source annotation from primitive procedures (which were not
supposed to be there in the first place)
2009-05-14 09:09:58 +03:00
