1 Wed Apr 5 14:32:51 1995 Gary Houston <ghouston@actrix.gen.nz>
3 * unix.c, ioext.c, posix.c, sys.c: Scheme name changes,
4 semantic cleanups, the port table, missing system calls
5 and coding cleanups from ghouston@actrix.gen.nz
7 Thu Mar 16 14:37:38 1995 Tom Lord <lord@x1.cygnus.com>
9 * guile.c: fixed the gcc-specific definition of the macro "AT(x)".
11 * guile.c (gscm_init_from_fn): Parameterize what init functions
12 get called (see guile_ks, below).
14 * guile-mini.c (guile_mini): a minimalist alternative to guile_ks.
16 * guile-ks.c (guile_ks): factor out the call to optional inits to
17 a separate file so you can link against libguile without getting
20 * Ginit.scm (try-load of "ScmInit.scm"): Be robust in the absense
21 of a binding for the environment varialbe HOME. Try
22 (getpw (geteuid)) or just use "/".
25 Thu Mar 9 15:35:20 1995 Tom Lord <lord@x1.cygnus.com>
27 * gmain.c (main): Print additional error message if init file
30 * guile.c (initialize_gscm): Report an error if the
31 init file can't be opened.
33 Thu Mar 23 23:22:59 1995 Aubrey Jaffer (jaffer@jacal)
35 * scm.texi (I/O-Extensions): Finished.
37 * Init.scm (scm:load): `loading' messages now indented.
39 Sat Mar 4 20:58:51 1995 Aubrey Jaffer (jaffer@jacal)
41 * scm.texi: documentation finished for "posix.c" and "unix.c".
43 * posix.c (scm_getgroups): added.
45 * posix.c (makfrom0str): According to glibc.info, some field in
46 structures like pwent may have NULL pointers. Changed makfrom0str
47 to return BOOL_F in this case.
49 Thu Mar 2 12:52:25 1995 Aubrey Jaffer (jaffer@jacal)
51 * time.c: CLKTCK set from CLOCKS_PER_SEC, if available. Metaware
54 * scm.h: USE_ANSI_PROTOTYPES now controls prototypes (was
55 __STDC__). This allows an overly fussy compiler to still have
58 From: dorai@ses.com (Dorai Sitaram)
59 * ioext.c (l_utime): include files fixed for __EMX__
61 Sun Feb 26 23:46:18 1995 Tom Lord <lord@x1.cygnus.com>
63 * repl.c (scm_app_wdr): Like scm_apply, but takes an error function.
64 The caller's continuation is never captured or escaped.
65 The error function is invoked as with scm_cwdr.
67 Sun Feb 26 21:03:04 1995 Aubrey Jaffer (jaffer@jacal)
69 * sys.c (gc_mark gc_sweep): tc7_ssymbol now gets GCed because it
70 gets used for non-GCed strings in scm_evalstr scm_loadstr.
71 (mkstrport cwos cwis): changed so caller's name is passed into
75 (scm_eval_string scm_evalstr scm_load_string scm_loadstr): added
76 for easier C to scheme callbacks.
77 (loadport): variable added so lreadr() and flush_ws()
78 increment linum only when reading from the correct port.
79 (def_err_response): now handles ARGn for argument numbers > 5 and
80 unknown position arguments.
82 * dynl.c: Dynamic Linking now sets and restores *load-pathname*
83 around the init_ call.
85 Sat Feb 25 11:03:56 1995 Aubrey Jaffer (jaffer@jacal)
87 * scm.c (lsystem getenv softtype ed vms_debug): moved from scl.c.
88 (add_feature): moved from repl.c.
89 (features): init table removed (caused multiple symbols).
91 Fri Feb 24 23:48:03 1995 Aubrey Jaffer (jaffer@jacal)
93 * scm.c (scm_init_extensions COMPILED_INITS): Added so that
94 statically linked, compiled code can be initialized *after* most
95 of Init.scm has loaded.
97 Wed Feb 22 15:54:01 1995 Aubrey Jaffer (jaffer@jacal)
99 * subr.c (append): Added check for bad arguments and fixed errobj.
101 Sun Feb 19 01:31:59 1995 Aubrey Jaffer (jaffer@jacal)
103 * ioext.c (exec execp): changed so that 2nd arguments is argv[0]
104 (like posix) and renamed to execl and execlp.
105 (execv execvp): added.
107 Sat Feb 11 17:30:14 1995 Aubrey Jaffer (jaffer@jacal)
109 * ioext.c (lexec): moved from repl.c and scm.c.
110 (lexecp i_exec l_putenv): added.
112 * posix.c (open_pipe l_open_input_pipe l_open_output_pipe
113 prinpipe): moved from ioext.c.
116 Fri Feb 10 10:50:03 1995 Aubrey Jaffer (jaffer@jacal)
118 * scl.c (num2long long2num): moved here from subr.c.
119 (num2ulong): fixed (< to >=) bug.
121 * unif.c (aset array2list array_ref cvref): uniform integers and
122 unsigned integer arrays now handle full size integers (and
123 inexacts) using num2long, num2ulong, long2num, and ulong2num when
124 INUMS_ONLY is not defined.
126 * scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.
128 Wed Feb 8 17:57:26 1995 Tom Lord (lord@x1.cygnus.com)
130 * Ginit.scm (stand-alone-repl): Use new function (rooted-repl)
131 (rooted-repl): new function
133 Tue Jan 31 16:46:26 1995 Tom Lord (lord@x1.cygnus.com)
135 * repl.c (lreadr): compare string constant names
136 in a case insensative way.
138 (scm_lread): Take an optional parameter CASEP.
139 If specified and not #f, then symbols are read
140 in a case sensative way.
142 If not specified, the state variable default_case_i is checked
143 (a C int, either 0 or 1). The state variable hasn't been
144 exposed and so is constant and depends on compile-time flags --
145 but in the future it might be made more explicit if there is a

150 * scm.texi (Overview): scm.1 converted to texinfo format and
153 Sat Jan 28 23:11:40 1995 Tom Lord (lord@x1.cygnus.com)
155 * repl.c (compiled-library-path): return the value of the
156 compile-time cpp macro "LIBRARY_PATH" or #f.
158 * Ginit.scm: use the above path to find slib on unix.
159 This solution should be generalized.
161 Fri Jan 27 19:58:27 1995 Tom Lord (lord@x1.cygnus.com)
163 * sys.c (gc_sweep): Fixed a gc bug that caused circular free-lists
164 resulting in Cells that thought they were free long after they
165 were allocated for some nefarious purpose or other.
167 * Makefile.in (manifest): ship all pieces of the info manual.
168 Typos fixes from ghouston.

212 Otherwise, use an empty string port. If using stdin, make it
215 Sun Jan 15 21:51:37 1995 Tom Lord <lord@x1.cygnus.com>
217 * sys.c (scm_mkarray, scm_free_array, mark_arrays): support for
218 C programs. malloc/free style interface to allcoating
219 protected storage of type SCM*.
221 Sun Jan 15 17:49:43 1995 Tom Lord (lord@x1.cygnus.com)
223 * guile.c: new file. Friendly C interface for Guile.
226 * repl.c (scm_cwdr): added call-with-dynamic-root (see scm.texi).
228 Sat Jan 14 23:35:21 1995 Tom Lord (lord@x1.cygnus.com)
230 * repl.c, subr.c: re-arrangement, commenting
231 of source in preparation for pulling repls apart
234 Wed Jan 11 14:45:17 1995 Aubrey Jaffer (jaffer@jacal)
236 * scl.c (num2ulong): checks for bignum sign and magnitude added.
238 * subr.c (logand logior logxor lognot): lognot restriction to
239 INUMs removed. Logand, logior, and logxor now will work for up to
240 32 bit signed numbers.
242 Tue Jan 10 13:19:52 1995 Aubrey Jaffer (jaffer@jacal)
244 * repl.c (def_err_response): Circuitous call to quit() replaced
245 with exit(EXIT_FAILURE);
246 (everr): Now calls def_err_response() in interrupt frame if
247 errjmp_bad or there are dynwinds to do. This prevents silent
248 failure in batch mode.
251 Mon Jan 9 00:12:14 1995 Aubrey Jaffer (jaffer@jacal)
253 * repl.c (handle_it): Now discards possibly used top freelist cell
254 for GC safety. Also now just punts if errjmp_bad.
256 * scm.texi: converted from MANUAL. GUILE documentation merged in.
258 Sat Jan 7 13:51:04 1995 Miles Bader (miles@eskimo.com)
260 * mrequire.scm: New file: Wrapper for slib require/provide that
261 makes it modular (that is, each slib package is loaded into its
262 own module, and sees only other modules that it requires).
264 * defmod.scm: Allow use-interface in the default module.
266 * libguile.scm: Put symbols common to both guile and scm
267 interfaces into the internal interface `EXTRA' (which is included
268 by both). Other random shuffling, mostly to make slib happy.
270 * modops.scm (extend-interface, export-interface, export): Add
271 another operation type, #f, which turns off automatic exporting of
272 the current source interface when finishing up with it. This is
273 used by export-interface to prevent trying to export all symbols.
275 * modops.scm (import): No longer signal an error when trying to
276 export a whole module, as we want to do this sometimes.
278 * Ginit.scm: No longer try to load require.scm, or depend on it;
279 In the case of getopt, we just load it manually. Also make
280 defmacro module-safe.
282 Sat Jan 7 01:54:11 1995 Tom Lord <lord@x1.cygnus.com>
284 * sys.c (scm_intern_obarray_soft): Reserve room for symbol slots.
286 * sys.c (scm_makstr, scm_makfromstr): added an extra parameter SLOTS.
288 0: same as the old behavior
290 > 1: allocate SLOTS - 1 extra slots in the string storage.
292 The base address of SLOTS, an array of SCM, is at SLOTS(obj).
293 This is for symbol slots, and later for procedure slots.
294 If you use this in the constructor for your new type (usually
295 done by creating a string and then invoking SETLENGTH to change
296 its type), you are responsible for making sure slot contents
299 Callers of these were fixed as well.
301 Tue Jan 3 14:30:34 1995 Miles Bader (miles@eskimo.com)
303 * modops.scm, extlibs.scm, libguile.scm, defmod.scm: New files:
304 These implement the user-level module system.
306 * sys.c (scm_sym2vcell): Add another argument: definedp, which is
307 passed as additional argument to the lookup-thunk (if any).
308 If this argument is BOOL_T, this lookup is for a define (which
309 has somewhat different semantics for modules); otherwise it
310 should be satisfied with an existing variable. If the thunk
311 returns BOOL_F (meaning there was no such variable), sym2vcell
312 returns BOOL_F as well.
313 * eval.c (scm_lookupcar, scm_m_define): Use the new sym2vcell param.
314 * variable.c (scm_builtin_var): Use the new sym2vcell param.
316 * eval.c (scm_top_level_env): New function: return an environment
317 using the given top-level-lookup thunk.
318 * eval.c (scm_eval2): Use scm_top_level_env.
319 * eval.c (scm_eval): Use an env with a top-level lookup thunk from
320 scm_top_level_lookup_thunk_var (aka *top-level-lookup-thunk*).
321 * eval.c (scm_neval): New function: just like scm_eval, but may
322 destroy its argument. Known in scheme as eval!.
324 * repl.c (scm_repl, scm_tryload, lreadr): Use scm_neval, not eval_3.
326 * Ginit.scm (make-module): Use the new definition of top-level thunks.
327 * Ginit.scm (set-current-module): Set *top-level-lookup-thunk* too.
328 * Ginit.scm: Trash all the repl stuff; we just use the C repl now.
329 Load the user module system.
331 * Makefile.in: Install the user-module implementation files.
333 Mon Jan 2 16:27:25 1995 Miles Bader (miles@eskimo.com)
335 * Ginit.scm (repl:repl): Have the guile repl redefine try-load
336 instead of load, as this is the SCM primitive.
337 (module-for-each): Write module-for-each.
338 (module-search): Make this recurse into each module use-list
339 entry, as per the low-level module spec.
340 (define-macro): Make this function usable by modules that don't
341 have access to the internals of the guile module.
343 Sun Jan 1 22:30:25 1995 Tom Lord <lord@x1.cygnus.com>
345 * repl.c (scm_iprin1), subr.c (scm_lock_vector, scm_unlock_vector,
346 scm_lvector_ref, scm_lvector_set):
348 Added locked vectors. See N
350 Sat Dec 31 15:45:22 1994 Miles Bader <miles@eskimo.com>
353 Add define-macro, delq!.
355 Add a module print-function, and some new name fields
356 to the module that the modops code uses to make modules
357 print nicely (e.g., #<interface guile/module 7a89c>)
360 * eval.c(ceval): Here's a patch that makes closures & subrs
364 Wed Dec 28 00:31:22 1994 Tom Lord <lord@cygnus.com>
366 * scm.c (raise): use kill not raise, since it is more portable.
368 Wed Dec 21 05:18:47 1994 Tom Lord <lord@x1.cygnus.com>
370 * eval.c (scm_eval2): Two argument eval. The
371 second argument is #f or a proc returning a variable.
373 Fri Dec 9 00:40:26 1994 Tom Lord <lord@x1.cygnus.com>
375 * eval.c (scm_fasl_eval): eval without copying the source form.
376 This is just a temporary hack.
378 Sun Dec 4 21:50:37 1994 Tom Lord <lord@x1.cygnus.com>
380 * eval.c (scm_ceval): Added special forms LITERAL-VARIABLE-SET!
381 and LITERAL-VARIABLE-REF. The first argument of each is a
382 variable object (see variable.c). The second argument
383 of set! is an expression. They do what you'd expect.
384 -SET! returns UNSPECIFIED.
386 Note that one can not read a form which uses literal-variable*
387 correctly because there is no way to read a variable object.
388 These forms exist for the sake of the module system.
390 Fri Dec 2 19:52:40 1994 Tom Lord (lord@x1.cygnus.com)
392 * subr.c (string->obarray-symbol, intern-symbol, unintern-symbol,
393 symbol-set!, symbol-binding)
396 * variable.c (scm_make_variable, scm_variable_{ref,set}
397 Implemented variables. Variables are anonymous
398 objects holding one settable value.
400 Wed Nov 30 04:31:18 1994 Tom Lord (lord@x1.cygnus.com)
402 * *.[ch]: renamed all global identifiers to have the prefix scm_.
404 * sys.c (gc_sweep, scm_mark_locations, scm_init_heap):
406 Modified gc to allow objects of any multiple of sizeof(CELLPTR).
407 In addition, each heap segment gets to specify a freelist (which
410 new function: scm_alloc_obj
411 new vars: scm_heap_table (replaces hplims)
412 scm_n_heap_segs (replaces (hpims_ind / 2))

416 From: Jerry D. Hedden <hedden@esdsdf.dnet.ge.com>
417 * ioext.c: conditional code for vms and version (3.6) of Aztec C.
418 * pi.scm ((e digits)): Modified 'bigpi' for slight speed
419 improvement. Added function to calculate digits of 'e'.
421 Wed Oct 26 11:22:05 1994 Aubrey Jaffer (jaffer@jacal)
423 From: Gary Houston <ghouston@actrix.gen.nz>
424 * scl.c (round): Now rounds as described in R4RS.
426 * test.scm (test-inexact): test cases for round.
428 Tue Oct 25 00:02:27 1994 Aubrey Jaffer (jaffer@jacal)
430 * sys.c (grow_throw lthrow dynthrow): now pass arrays, check
431 for adequate growth, and clear out register windows (on sparc).
433 Mon Oct 24 01:05:34 1994 Aubrey Jaffer (jaffer@jacal)
435 * ioext.c (ttyname fileno): added.
437 Sat Oct 22 12:12:57 1994 Aubrey Jaffer (jaffer@jacal)
439 * unix.c (symlink readlink lstat): added.
441 * scmfig.h repl.c sys.c (IO_EXTENSIONS): flag removed.

444 reopen-file open-pipe opendir readdir rewinddir closedir chdir
445 umask rename-file isatty? access chmod mkdir rmdir stat utime

450 From: Radey Shouman <shouman@ccwf.cc.utexas.edu>

452 whether copying is necessary or not. Eliminates gratuitous copy
453 by UNIFORM-ARRAY-READ! when called with a noncontiguous array.
455 (array_map): more liberal check on when ARRAY-MAP! can use
458 Thu Oct 20 18:00:35 1994 Aubrey Jaffer (jaffer@jacal)

466 and apply() arg counts.

504 Tue Sep 6 22:22:16 1994 Aubrey Jaffer (jaffer@jacal)
506 From: rshouman@hpcf.cc.utexas.edu (Radey Shouman)
507 Date: Mon, 29 Aug 1994 11:36:46 +0600
508 * unif.c: This is a large patch, but also a bit larger than it
509 appears -- I moved a few function definitions around to eliminate
510 gratuitous forward references.
512 * unif.c repl.c (raprin1): Combined print routine for arrays with
515 * unif.c (UNIFORM-VECTOR-READ! and -WRITE): work with general
516 arrays, by copying when necessary, renamed them to
517 UNIFORM-ARRAY-READ! and -WRITE.
519 * unif.c (ARRAY-CONTENTS): Generalized so that it returns a 1-d
520 array even when the stride in the last dimension is greater than
521 one, gave it an optional second argument STRICT, which makes it
522 behave as it did before, returning an array/vector only if the
523 contents are contiguous in memory.
525 * unif.c (ARRAY-CONTIGUOUS?) Eliminated. Instead, use
526 (lambda (ra) (array? (array-contents ra #t)))
528 * unif.c code.doc (ramapc): unrolls arrays mapping into one loop
529 if possible, to make this quick, changed the format of the array
530 CAR, now uses one bit to indicate that an array is contiguous --
531 this still allows a ridiculous number of dimensions.
533 * scm.h (DSUBRF): dsubrs are mapped directly, to allow this I
534 moved the typedef for dsubr and #define for DSUBRF to scm.h
536 * unif.c (ARRAY-MAP!) taught something about subrs, now most subrs
537 may be mapped without going through apply(), saving time and
538 reducing consing. +, -, *, /, =, <, <=, >, and >= are mapped
539 directly as special cases -- for uniform arrays this is nearly as
540 fast as the equivalent C, and doesnt' cons. I've made sure that
541 +, -, *, and / vectorize on the CRAY, this may be wasted effort
542 but the effort is not great.
544 * unif.c (ARRAY-COPY!) now copies many arrays of differing types
545 to each other without going through the aref/aset, e.g. float ->
546 double, double -> complex, integer -> float ... This should make
547 array type coercions for arithmetic faster.
549 * unif.c (TRANSPOSE-ARRAY) Added, which returns a shared array
550 that is the transpose of its first argument. I think this does
551 what an APL:TRANSPOSE would.
553 * unif.c (ENCLOSE-ARRAY) Added, this returns an array that looks
554 like an array of shared arrays, the difference being that the
555 shared arrays are not actually allocated until referenced.
556 Internally, the contents of an enclosed array is another array.
557 The main reason for this is to allow a reasonably efficient
558 implementation of APL:COMPRESS, EXPAND, and INDEXING. In order to
559 actually make an array of shared arrays, just use ARRAY-COPY!.
561 * unif.c (cvref): Created internal version of aref(), cvref() that
562 doesn't do error checking; Thus speeding things up. Profiling of
563 SCM running array code revealed that aref() was taking a
564 surprising fraction of the CPU time
568 The mechanism for looking up the vectorized functions is a little
569 kludgy, I was tempted to steal some of the CAR of the subr type to
570 encode an offset into a table of vectorized functions, but this
571 would make it more likely that dynamically loaded subrs lose thier
574 It is almost possible to write APL:+ and friends now, it is just
575 necessary to figure out the appropriate type of the returned array
576 and allocate it, and to promote scalar arguments to arrays (with
579 This doesn't include vectorized REAL-PART, IMAG-PART,
582 I think some C support for APL:REDUCE and maybe INNER-PRODUCT will
583 be needed for a reasonably fast APL.scm
585 unif.c is getting quite big, time to split it up?

2088 bug with characters > 128 in symbols.
2090 * scl.c (eqv? memv assv): created if FLOATS is #defined. From
2091 boopsy!mike@maccs.dcss.mcmaster.ca (Michael A. Borza).
2093 Mon Dec 2 11:37:11 1991 Aubrey Jaffer (jaffer at Ivan)
2095 * patchlvl.h (PATCHLEVEL): 4
2097 * sys.c (gc_sweep): usaage of pclose() now conditional on unix.
2099 * MANUAL (chdir): documented.
2101 from T. Kurt Bond, Adminisoft, Inc. <tkb@MTNET2.WVNET.EDU>:
2103 * repl.c sys.c (errno): VMS GNU C uses a special hack in <errno.h>
2104 to get the link-time attributes for the errno variable to match
2105 those the VMS C run-time library expects (it makes errno a
2106 preprocessor define so that the variable that the compiler sees
2107 has a special form that the assember then interprets), so if it is
2108 VMS and __GNUC__ is defined <errno.h> needs included.
2110 * setjump.h (SETJUMP LONGJUMP): SETJUMP and LONGJUMP changed to
2111 setjump and longjump. The VMS linker is case-indifferent. VMS GNU
2112 C mangles variable names that have upper case letters in them to
2113 preserve their uniqueness.
2115 * sys.c (iprint iprin1): Now inline putc loops instead of calls to
2116 fwrite for VMS. The VMS `fwrite' has been enhanced to work with
2117 VMS's Record Management Sevice, RMS. Part of this enhancement is
2118 to treat each call to `fwrite' as producing a separate record.
2119 This works fine if you are writing to a stream_LF file or an
2120 actual terminal screen, but if you are writing to a file that has
2121 implied carriage control (such as a batch log file, or a mailbox
2122 used for subprocess communication), which is a more common file
2123 organization for RMS, each call to `fwrite' has a newline appended
2124 to it. This causes much of the output to be incorrectly split
2127 * vmsgcc.com: created.
2129 Sun Dec 1 00:33:42 1991 Aubrey Jaffer (jaffer at Ivan)
