asciilifeform_shi... 72 Error checking of binding spec syntax in LET*
asciilifeform_shi... 73 Bad syntax was causing core dump in Linux.
asciilifeform_shi... 74 Fix for nasty gc bug
asciilifeform_shi... 75
asciilifeform_shi... 76 R5RS changes:
asciilifeform_shi... 77 R5RS requires numbers to be of equal value AND of the same type (ie. both
asciilifeform_shi... 78 exact or inexact) in order to return #t from eqv?. R5RS compliance fix.
asciilifeform_shi... 79 String output ports now conform to SRFI-6
asciilifeform_shi... 80

asciilifeform_shi... 87
asciilifeform_shi... 88 Version 1.38
asciilifeform_shi... 89 Interim release until the rewrite, mostly incorporating modifications
asciilifeform_shi... 90 from Kevin Cozens. Small addition for Cygwin in the makefile, and
asciilifeform_shi... 91 modifications by Andrew Guenther for Apple platforms.
asciilifeform_shi... 92
asciilifeform_shi... 93 Version 1.37
asciilifeform_shi... 94 Joe Buehler submitted reserve_cells.
asciilifeform_shi... 95
asciilifeform_shi... 96 Version 1.36
asciilifeform_shi... 97 Joe Buehler fixed a patch in the allocator.
asciilifeform_shi... 98 Alexander Shendi moved the comment handling in the scanner, which
asciilifeform_shi... 99 fixed an obscure bug for which Mike E had provided a patch as well.
asciilifeform_shi... 100 Kevin Cozens has submitted some fixes and modifications which have
asciilifeform_shi... 101 not been incorporated yet in their entirety.
asciilifeform_shi... 102
asciilifeform_shi... 103 Version 1.35
asciilifeform_shi... 104 Todd Showalter discovered that the number of free cells reported
asciilifeform_shi... 105 after GC was incorrect, which could also cause unnecessary allocations.
asciilifeform_shi... 106
asciilifeform_shi... 107 Version 1.34
asciilifeform_shi... 108 Long missing version. Lots of bugfixes have accumulated in my email, so
asciilifeform_shi... 109 I had to start using them. In this version, Keenan Pepper has submitted
asciilifeform_shi... 110 a bugfix for the string comparison library procedure, Wouter Boeke
asciilifeform_shi... 111 modified some code that was casting to the wrong type and crashed on
asciilifeform_shi... 112 some machines, "SheppardCo" submitted a replacement "modulo" code and
asciilifeform_shi... 113 Scott Fenton submitted lots of corrections that shut up some compiler
asciilifeform_shi... 114 warnings. Brian Maher submitted instructions on how to build on OS-X.
asciilifeform_shi... 115 I have to dig deeper into my mailbox and find earlier emails, too.
asciilifeform_shi... 116
asciilifeform_shi... 117 Version 1.33
asciilifeform_shi... 118 Charles Hayden fixed a nasty GC bug of the new stack frame, while in
asciilifeform_shi... 119 the process of porting TinyScheme to C++. He also submitted other
asciilifeform_shi... 120 changes, and other people also had comments or requests, but the GC
asciilifeform_shi... 121 bug was so important that this version is put through the door to
asciilifeform_shi... 122 correct it.
asciilifeform_shi... 123
asciilifeform_shi... 124 Version 1.32
asciilifeform_shi... 125 Stephen Gildea put some quality time on TinyScheme again, and made
asciilifeform_shi... 126 a whole lot of changes to the interpreter that made it noticeably
asciilifeform_shi... 127 faster.
asciilifeform_shi... 128
asciilifeform_shi... 129 Version 1.31
asciilifeform_shi... 130 Patches to the hastily-done version 1.30. Stephen Gildea fixed
asciilifeform_shi... 131 some things done wrongly, and Richard Russo fixed the makefile
asciilifeform_shi... 132 for building on Windows. Property lists (heritage from MiniScheme)
asciilifeform_shi... 133 are now optional and have dissappeared from the interface. They
asciilifeform_shi... 134 should be considered as deprecated.
asciilifeform_shi... 135
asciilifeform_shi... 136 Version 1.30
asciilifeform_shi... 137 After many months, I followed Preston Bannister's advice of
asciilifeform_shi... 138 using macros and a single source text to keep the enums and the
asciilifeform_shi... 139 dispatch table in sync, and I used his contributed "opdefines.h".
asciilifeform_shi... 140 Timothy Downs contributed a helpful function, "scheme_call".
asciilifeform_shi... 141 Stephen Gildea contributed new versions of the makefile and
asciilifeform_shi... 142 practically all other sources. He created a built-in STRING-APPEND,
asciilifeform_shi... 143 and fixed a lot of other bugs.
asciilifeform_shi... 144 Ruhi Bloodworth reported fixes necessary for OS X and a small
asciilifeform_shi... 145 bug in dynload.c.
asciilifeform_shi... 146
asciilifeform_shi... 147 Version 1.29
asciilifeform_shi... 148 The previous version contained a lot of corrections, but there
asciilifeform_shi... 149 were a lot more that still wait on a sheet of paper lost in a
asciilifeform_shi... 150 carton someplace after my house move... Manuel Heras-Gilsanz
asciilifeform_shi... 151 noticed this and resent his own contribution, which relies on
asciilifeform_shi... 152 another bugfix that v.1.28 was missing: a problem with string
asciilifeform_shi... 153 output, that this version fixes. I hope other people will take
asciilifeform_shi... 154 the time to resend their contributions, if they didn't make it
asciilifeform_shi... 155 to v.1.28.
asciilifeform_shi... 156
asciilifeform_shi... 157 Version 1.28
asciilifeform_shi... 158 Many people have contacted me with bugfixes or remarks in
asciilifeform_shi... 159 the three months I was inactive. A lot of them spotted that
asciilifeform_shi... 160 scheme_deinit crashed while reporting gc results. They suggested
asciilifeform_shi... 161 that sc->outport be set to NIL in scheme_deinit, which I did.
asciilifeform_shi... 162 Dennis Taylor remarked that OP_VALUEPRINT reset sc->value instead
asciilifeform_shi... 163 of preserving it. He submitted a modification which I adopted
asciilifeform_shi... 164 partially. David Hovemeyer sent me many little changes, that you
asciilifeform_shi... 165 will find in version 1.28, and Partice Stoessel modified the
asciilifeform_shi... 166 float reader to conform to R5RS.
asciilifeform_shi... 167
asciilifeform_shi... 168 Version 1.27
asciilifeform_shi... 169 Version 1.27 is the successor of 1.25. Bug fixes only, but I had to
asciilifeform_shi... 170 release them so that everybody can profit. 'Backchar' tried to write
asciilifeform_shi... 171 back to the string, which obviously didn't work for const strings.
asciilifeform_shi... 172 'Substring' didn't check for crossed start and end indices. Defines
asciilifeform_shi... 173 changed to restore the ability to compile under MSVC.
asciilifeform_shi... 174
asciilifeform_shi... 175 Version 1.26
asciilifeform_shi... 176 Version 1.26 was never released. I changed a lot of things, in fact
asciilifeform_shi... 177 too much, even the garbage collector, and hell broke loose. I'll
asciilifeform_shi... 178 try a more gradual approach next time.
asciilifeform_shi... 179
asciilifeform_shi... 180 Version 1.25
asciilifeform_shi... 181 Types have been homogenized to be able to accommodate a different
asciilifeform_shi... 182 representation. Plus, promises are no longer closures. Unfortunately,
asciilifeform_shi... 183 I discovered that continuations and force/delay do not pass the SCM
asciilifeform_shi... 184 test (and never did)... However, on the bright side, what little
asciilifeform_shi... 185 modifications I did had a large impact on the footprint:
asciilifeform_shi... 186 USE_NO_FEATURES now produces an object file of 63960 bytes on Linux!
asciilifeform_shi... 187
asciilifeform_shi... 188 Version 1.24
asciilifeform_shi... 189 SCM tests now pass again after change in atom2str.
asciilifeform_shi... 190
asciilifeform_shi... 191 Version 1.23
asciilifeform_shi... 192 Finally I managed to mess it up with my version control. Version
asciilifeform_shi... 193 1.22 actually lacked some of the things I have been fixing in the
asciilifeform_shi... 194 meantime. This should be considered as a complete replacement for
asciilifeform_shi... 195 1.22.
asciilifeform_shi... 196
asciilifeform_shi... 197 Version 1.22
asciilifeform_shi... 198 The new ports had a bug in LOAD. MK_CLOSURE is introduced.
asciilifeform_shi... 199 Shawn Wagner inquired about string->number and number->string.
asciilifeform_shi... 200 I added string->atom and atom->string and defined the number
asciilifeform_shi... 201 functions from them. Doing that, I fixed WRITE applied to symbols
asciilifeform_shi... 202 (it didn't quote them). Unfortunately, minimum build is now
asciilifeform_shi... 203 slightly larger than 64k... I postpone action because Jason's idea
asciilifeform_shi... 204 might solve it elegantly.
asciilifeform_shi... 205
asciilifeform_shi... 206 Version 1.21
asciilifeform_shi... 207 Jason Felice submitted a radically different datatype representation
asciilifeform_shi... 208 which he had implemented. While discussing its pros and cons, it
asciilifeform_shi... 209 became apparent that the current implementation of ports suffered
asciilifeform_shi... 210 from a grave fault: ports were not garbage-collected. I changed the
asciilifeform_shi... 211 ports to be heap-allocated, which enabled the use of string ports
asciilifeform_shi... 212 for loading. Jason also fixed errors in the garbage collection of
asciilifeform_shi... 213 vectors. USE_VERBATIM is gone. "ssp_compiler.c" has a better solution
asciilifeform_shi... 214 on HTML generation. A bug involving backslash notation in strings
asciilifeform_shi... 215 has been fixed. '-c' flag now executes next argument as a stream of
asciilifeform_shi... 216 Scheme commands. Foreign functions are now also heap allocated,
asciilifeform_shi... 217 and scheme_define is used to define everything.
asciilifeform_shi... 218
asciilifeform_shi... 219 Version 1.20
asciilifeform_shi... 220 Tracing has been added. The toplevel loop has been slightly
asciilifeform_shi... 221 rearranged. Backquote reading for vector templates has been
asciilifeform_shi... 222 sanitized. Symbol interning is now correct. Arithmetic functions
asciilifeform_shi... 223 have been corrected. APPLY, MAP, FOR-EACH, numeric comparison
asciilifeform_shi... 224 functions fixed. String reader/writer understands \xAA notation.
asciilifeform_shi... 225
asciilifeform_shi... 226 Version 1.19
asciilifeform_shi... 227 Carriage Return now delimits identifiers. DOS-formatted Scheme files
asciilifeform_shi... 228 can be used by Unix. Random number generator added to library.
asciilifeform_shi... 229 Fixed some glitches of the new type-checking scheme. Fixed erroneous
asciilifeform_shi... 230 (append '() 'a) behavior. Will continue with r4rstest.scm to
asciilifeform_shi... 231 fix errors.
asciilifeform_shi... 232
asciilifeform_shi... 233 Version 1.18
asciilifeform_shi... 234 The FFI has been extended. USE_VERBOSE_GC has gone. Anyone wanting
asciilifeform_shi... 235 the same functionality can put (gcverbose #t) in init.scm.
asciilifeform_shi... 236 print-width was removed, along with three corresponding op-codes.
asciilifeform_shi... 237 Extended character constants with ASCII names were added.
asciilifeform_shi... 238 mk_counted_string paves the way for full support of binary strings.
asciilifeform_shi... 239 As much as possible of the type-checking chores were delegated
asciilifeform_shi... 240 to the inner loop, thus reducing the code size to less than 4200 loc!
asciilifeform_shi... 241
asciilifeform_shi... 242 Version 1.17
asciilifeform_shi... 243 Dynamically-loaded extensions are more fully integrated.
asciilifeform_shi... 244 TinyScheme is now distributed under the BSD open-source license.
asciilifeform_shi... 245
asciilifeform_shi... 246 Version 1.16
asciilifeform_shi... 247 Dynamically-loaded extensions introduced (USE_DL).
asciilifeform_shi... 248 Santeri Paavolainen found a race condition: When a cons is executed,
asciilifeform_shi... 249 and each of the two arguments is a constructing function, GC could
asciilifeform_shi... 250 happen before all arguments are evaluated and cons() is called, and
asciilifeform_shi... 251 the evaluated arguments would all be reclaimed!
asciilifeform_shi... 252 Fortunately, such a case was rare in the code, although it is
asciilifeform_shi... 253 a pitfall in new code and code in foreign functions. Currently, only
asciilifeform_shi... 254 one such case remains, when COLON_HOOK is defined.
asciilifeform_shi... 255
asciilifeform_shi... 256 Version 1.15
asciilifeform_shi... 257 David Gould also contributed some changes that speed up operation.
asciilifeform_shi... 258 Kirk Zurell fixed HASPROP.
asciilifeform_shi... 259 The Garbage Collection didn't collect all the garbage...fixed.
asciilifeform_shi... 260
asciilifeform_shi... 261 Version 1.14
asciilifeform_shi... 262 Unfortunately, after Andre fixed the GC it became obvious that the
asciilifeform_shi... 263 algorithm was too slow... Fortunately, David Gould found a way to
asciilifeform_shi... 264 speed it up.
asciilifeform_shi... 265
asciilifeform_shi... 266 Version 1.13
asciilifeform_shi... 267 Silly bug involving division by zero resolved by Roland Kaufman.
asciilifeform_shi... 268 Macintoch support from Shmulik Regev.
asciilifeform_shi... 269 Float parser bug fixed by Alexander Shendi.
asciilifeform_shi... 270 GC bug from Andru Luvisi.
asciilifeform_shi... 271
asciilifeform_shi... 272 Version 1.12
asciilifeform_shi... 273 Cis* incorrectly called isalpha() instead of isascii()
asciilifeform_shi... 274 Added USE_CHAR_CLASSIFIERS, USE_STRING_PORTS.
asciilifeform_shi... 275
asciilifeform_shi... 276 Version 1.11
asciilifeform_shi... 277 BSDI defines isnumber... changed all similar functions to is_*
asciilifeform_shi... 278 EXPT now has correct definition. Added FLOOR,CEILING,TRUNCATE
asciilifeform_shi... 279 and ROUND, courtesy of Bengt Kleberg. Preprocessor symbols now
asciilifeform_shi... 280 have values 1 or 0, and can be set as compiler defines (proposed
asciilifeform_shi... 281 by Andy Ganor *months* ago). 'prompt' and 'InitFile' can now be
asciilifeform_shi... 282 defined during compilation, too.
asciilifeform_shi... 283
asciilifeform_shi... 284 Version 1.10
asciilifeform_shi... 285 Another bug when file ends with comment!
asciilifeform_shi... 286 Added DEFINE-MACRO in init.scm, courtesy of Andy Gaynor.
asciilifeform_shi... 287

asciilifeform_shi... 295 '=>' in cond now exists
asciilifeform_shi... 296 list? now checks for circularity
asciilifeform_shi... 297 some reader bugs removed
asciilifeform_shi... 298 Reader is more consistent wrt vectors
asciilifeform_shi... 299 Quote and Quasiquote work with vectors
asciilifeform_shi... 300
asciilifeform_shi... 301 Version 1.06
asciilifeform_shi... 302 #! is now skipped
asciilifeform_shi... 303 generic-assoc bug removed
asciilifeform_shi... 304 strings are now managed differently, hack.txt is removed
asciilifeform_shi... 305 various delicate points fixed
asciilifeform_shi... 306
asciilifeform_shi... 307 Version 1.05
asciilifeform_shi... 308 Support for scripts, *args*, "-1" option.
asciilifeform_shi... 309 Various R5RS procedures.

asciilifeform_shi... 315 Added missing T_ATOM bits...
asciilifeform_shi... 316 Added vectors
asciilifeform_shi... 317 Free-list is sorted by address, since vectors need consecutive cells.
asciilifeform_shi... 318 (quit <exitcode>) for use with scripts
asciilifeform_shi... 319
asciilifeform_shi... 320 Version 1.03 (26 Aug 1998):
