Small addition for Cygwin in the makefile, and + modifications by Andrew Guenther for Apple platforms. + +Version 1.37 + Joe Buehler submitted reserve_cells. + +Version 1.36 + Joe Buehler fixed a patch in the allocator. + Alexander Shendi moved the comment handling in the scanner, which + fixed an obscure bug for which Mike E had provided a patch as well. + Kevin Cozens has submitted some fixes and modifications which have + not been incorporated yet in their entirety. + +Version 1.35 + Todd Showalter discovered that the number of free cells reported + after GC was incorrect, which could also cause unnecessary allocations. + +Version 1.34 + Long missing version. Lots of bugfixes have accumulated in my email, so + I had to start using them. In this version, Keenan Pepper has submitted + a bugfix for the string comparison library procedure, Wouter Boeke + modified some code that was casting to the wrong type and crashed on + some machines, "SheppardCo" submitted a replacement "modulo" code and + Scott Fenton submitted lots of corrections that shut up some compiler + warnings. Brian Maher submitted instructions on how to build on OS-X. + I have to dig deeper into my mailbox and find earlier emails, too. + +Version 1.33 + Charles Hayden fixed a nasty GC bug of the new stack frame, while in + the process of porting TinyScheme to C++. He also submitted other + changes, and other people also had comments or requests, but the GC + bug was so important that this version is put through the door to + correct it. + +Version 1.32 + Stephen Gildea put some quality time on TinyScheme again, and made + a whole lot of changes to the interpreter that made it noticeably + faster. + +Version 1.31 + Patches to the hastily-done version 1.30. Stephen Gildea fixed + some things done wrongly, and Richard Russo fixed the makefile + for building on Windows. Property lists (heritage from MiniScheme) + are now optional and have disappeared from the interface. They + should be considered as deprecated. + +Version 1.30 + After many months, I followed Preston Bannister's advice of + using macros and a single source text to keep the enums and the + dispatch table in sync, and I used his contributed "opdefines.h". + Timothy Downs contributed a helpful function, "scheme_call". + Stephen Gildea contributed new versions of the makefile and + practically all other sources. He created a built-in STRING-APPEND, + and fixed a lot of other bugs. + Ruhi Bloodworth reported fixes necessary for OS X and a small + bug in dynload.c. + +Version 1.29 + The previous version contained a lot of corrections, but there + were a lot more that still wait on a sheet of paper lost in a + carton someplace after my house move... Manuel Heras-Gilsanz + noticed this and resent his own contribution, which relies on + another bugfix that v.1.28 was missing: a problem with string + output, that this version fixes. I hope other people will take + the time to resend their contributions, if they didn't make it + to v.1.28. + +Version 1.28 + Many people have contacted me with bugfixes or remarks in + the three months I was inactive. A lot of them spotted that + scheme_deinit crashed while reporting gc results. They suggested + that sc->outport be set to NIL in scheme_deinit, which I did. + Dennis Taylor remarked that OP_VALUEPRINT reset sc->value instead + of preserving it. He submitted a modification which I adopted + partially. David Hovemeyer sent me many little changes, that you + will find in version 1.28, and Partice Stoessel modified the + float reader to conform to R5RS. + +Version 1.27 + Version 1.27 is the successor of 1.25. Bug fixes only, but I had to + release them so that everybody can profit. 'Backchar' tried to write + back to the string, which obviously didn't work for const strings. + 'Substring' didn't check for crossed start and end indices. Defines + changed to restore the ability to compile under MSVC. + +Version 1.26 + Version 1.26 was never released. I changed a lot of things, in fact + too much, even the garbage collector, and hell broke loose. I'll + try a more gradual approach next time. + +Version 1.25 + Types have been homogenized to be able to accommodate a different + representation. Plus, promises are no longer closures. Unfortunately, + I discovered that continuations and force/delay do not pass the SCM + test (and never did)... However, on the bright side, what little + modifications I did had a large impact on the footprint: + USE_NO_FEATURES now produces an object file of 63960 bytes on Linux! + +Version 1.24 + SCM tests now pass again after change in atom2str. + +Version 1.23 + Finally I managed to mess it up with my version control. Version + 1.22 actually lacked some of the things I have been fixing in the + meantime. This should be considered as a complete replacement for + 1.22. + +Version 1.22 + The new ports had a bug in LOAD. MK_CLOSURE is introduced. + Shawn Wagner inquired about string->number and number->string. + I added string->atom and atom->string and defined the number + functions from them. Doing that, I fixed WRITE applied to symbols + (it didn't quote them). Unfortunately, minimum build is now + slightly larger than 64k... I postpone action because Jason's idea + might solve it elegantly. + +Version 1.21 + Jason Felice submitted a radically different datatype representation + which he had implemented. While discussing its pros and cons, it + became apparent that the current implementation of ports suffered + from a grave fault: ports were not garbage-collected. I changed the + ports to be heap-allocated, which enabled the use of string ports + for loading. Jason also fixed errors in the garbage collection of + vectors. USE_VERBATIM is gone. "ssp_compiler.c" has a better solution + on HTML generation. A bug involving backslash notation in strings + has been fixed. '-c' flag now executes next argument as a stream of + Scheme commands. Foreign functions are now also heap allocated, + and scheme_define is used to define everything. + +Version 1.20 + Tracing has been added. The toplevel loop has been slightly + rearranged. Backquote reading for vector templates has been + sanitized. Symbol interning is now correct. Arithmetic functions + have been corrected. APPLY, MAP, FOR-EACH, numeric comparison + functions fixed. String reader/writer understands \xAA notation. + +Version 1.19 + Carriage Return now delimits identifiers. DOS-formatted Scheme files + can be used by Unix. Random number generator added to library. + Fixed some glitches of the new type-checking scheme. Fixed erroneous + (append '() 'a) behavior. Will continue with r4rstest.scm to + fix errors. + +Version 1.18 + The FFI has been extended. USE_VERBOSE_GC has gone. Anyone wanting + the same functionality can put (gcverbose #t) in init.scm. + print-width was removed, along with three corresponding op-codes. + Extended character constants with ASCII names were added. + mk_counted_string paves the way for full support of binary strings. + As much as possible of the type-checking chores were delegated + to the inner loop, thus reducing the code size to less than 4200 loc! + +Version 1.17 + Dynamically-loaded extensions are more fully integrated. + TinyScheme is now distributed under the BSD open-source license. + +Version 1.16 + Dynamically-loaded extensions introduced (USE_DL). + Santeri Paavolainen found a race condition: When a cons is executed, + and each of the two arguments is a constructing function, GC could + happen before all arguments are evaluated and cons() is called, and + the evaluated arguments would all be reclaimed! + Fortunately, such a case was rare in the code, although it is + a pitfall in new code and code in foreign functions. Currently, only + one such case remains, when COLON_HOOK is defined. + +Version 1.15 + David Gould also contributed some changes that speed up operation. + Kirk Zurell fixed HASPROP. + The Garbage Collection didn't collect all the garbage...fixed. + +Version 1.14 + Unfortunately, after Andre fixed the GC it became obvious that the + algorithm was too slow... Fortunately, David Gould found a way to + speed it up. + +Version 1.13 + Silly bug involving division by zero resolved by Roland Kaufman. + Macintoch support from Shmulik Regev. + Float parser bug fixed by Alexander Shendi. + GC bug from Andru Luvisi. + +Version 1.12 + Cis* incorrectly called isalpha() instead of isascii() + Added USE_CHAR_CLASSIFIERS, USE_STRING_PORTS. + +Version 1.11 + BSDI defines isnumber... changed all similar functions to is_* + EXPT now has correct definition. Added FLOOR,CEILING,TRUNCATE + and ROUND, courtesy of Bengt Kleberg. Preprocessor symbols now + have values 1 or 0, and can be set as compiler defines (proposed + by Andy Ganor *months* ago). 'prompt' and 'InitFile' can now be + defined during compilation, too. + +Version 1.10 + Another bug when file ends with comment! + Added DEFINE-MACRO in init.scm, courtesy of Andy Gaynor. + +Version 1.09 + Removed bug when READ met EOF. lcm. + +Version 1.08 + quotient,remainder and modulo. gcd. + +Version 1.07 + '=>' in cond now exists + list? now checks for circularity + some reader bugs removed + Reader is more consistent wrt vectors + Quote and Quasiquote work with vectors + +Version 1.06 + #! is now skipped + generic-assoc bug removed + strings are now managed differently, hack.txt is removed + various delicate points fixed + +Version 1.05 + Support for scripts, *args*, "-1" option. + Various R5RS procedures. + *sharp-hook* + Handles unmatched parentheses. + New architecture for procedures. + +Version 1.04 + Added missing T_ATOM bits... + Added vectors + Free-list is sorted by address, since vectors need consecutive cells. + (quit <exitcode>) for use with scripts + +Version 1.03 (26 Aug 1998): + Extended .h with useful functions for FFI + Library: with-input-* etc. + Finished R5RS I/O, added string ports. + +Version 1.02 (25 Aug 1998): + First part of R5RS I/O. |
