Release History for pForth - a Portable ANS-like Forth written in ANSI 'C'
Documentation for pForth at http://www.softsynth.com/pforth/
V28 - unreleased
- fixes for MinGW build
V27 - 11/22/2010
- Fixed REPOSITION-FILE FILE-SIZE and FILE-POSITION.
They used to use single precision offset. Now use double as specified.
- Delete object directories in Makefile clean.
- Fixed "Issue 4: Filehandle remains locked upon INCLUDE error".
http://code.google.com/p/pforth/issues/detail?id=4&can=1
- Fixed scrambled HISTORY on 64-bit systems. Was using CELL+ but really needed 4 +.
- Fixed floating point input. Now accepts "1E" as 1.0. Was Issue #2.
- Fixed lots of warning and made code compatible with C89 and ANSI. Uses -pedantic.
- Use fseek and ftell on WIN32 instead of fseeko and ftello.
- Makefile is now more standard. Builds in same dir as Makefile. Uses CFLAGS etc.
- Add support for console IO with _WATCOMC_
- Internal CStringToForth and ForthStringToC now take a destination size for safety.
- Run units tests for CStringToForth and ForthStringToC if PF_UNIT_TESTS is defined.
V26 5/20/2010
- 64-bit support for M* UM/MOD etc by Aleksej Saushev. Thanks Aleksej!
V25 5/19/2010
- Added 64-bit CELL support contributed by Aleksej Saushev. Thanks Aleksej!
- Added "-x c" to Makefile CCOPTS to prevent confusion with C++
- Allow space after -d command line option.
- Restore normal tty mode if pForth dictionary loading fails.
V24 2/20/09
- Fixed Posix IO on Mac. ?TERMINAL was always returning true.
- ACCCEPT now emits a space at end of line before output.
- Fixed RESIZE because it was returning the wrong address.
V23 8/4/2008
- Removed -v option from mkdir in build/unix/Makefile. It was not supported on FreeBSD.
Thank you Alexsej Saushev for reporting this.
V23 7/20/2008
- Reorganized for Google Code project.
V22 (unreleased)
- Added command line history and cursor control words.
- Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.
- Modified ACCEPT so that a line at the end of a file that does NOT have a line
terminator will now be processed.
- Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.
- Fixed : foo { -- } 55 ; - Was entering local frame but not exiting. Now prints error.
- Redefined MAKE_ID to protect it from 16 bit ints
- John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \
- Fixed float evaluation in EVALUATE in "quit.fth".
- Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;
V21 - 9/16/1998
- Fixed some compiler warnings.
V20
- Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.
Thank you Michael Connor of Vancouver for reporting this bug.
- Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".
Thank you Jim Rosenow of Minnesota for reporting this bug.
- Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS
Thank you Jim Rosenow of Minnesota for reporting this bug.
- "0.0 F~" now checks actual binary encoding of floats. Before this it used to just
compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.
- Fixed definition of INPUT$ in tutorial.
Thank you Hampton Miller of California for reporting this bug.
- Added support for producing a target dictionary with a different
Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.
- PForth kernel now comes up in a mode that uses BASE for numeric input when
started with "-i" option. It used to always consider numeric input as HEX.
Initial BASE is decimal.
V19 4/1998
- Warn if local var name matches dictionary, : foo { count -- } ;
- TO -> and +-> now parse input stream. No longer use to-flag.
- TO -> and +-> now give error if used with non-immediate word.
- Added (FLITERAL) support to SEE.
- Aded TRACE facility for single step debugging of Forth words.
- Added stub for ?TERMINAL and KEY? for embedded systems.
- Added PF_NO_GLOBAL_INIT for no reliance on global initialization.
- Added PF_USER_FLOAT for customization of FP support.
- Added floating point to string conversion words (F.) (FS.) (FE.)
For example: : F. (F.) TYPE SPACE ;
- Reversed order that values are placed on return stack in 2>R
so that it matches ANS standard. 2>R is now same as SWAP >R >R
Thank you Leo Wong for reporting this bug.
- Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.
- FIXED memory leak in pfDoForth()
V18
- Make FILL a 'C' primitive.
- optimized locals with (1_LOCAL@)
- optimized inner interpreter by 15%
- fix tester.fth failures

- Fixed saving and restoring of TIB when nesting include files.
V17
- Fixed input of large floats. 0.7071234567 F. used to fail.
V16
* Define PF_USER_CUSTOM if you are defining your own custom
'C' glue routines. This will ifndef the published example.
- Fixed warning in pf_cglue.c.
- Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code
if called when (BASE != 10), as in HEX mode.
- Fixed address comparisons in forget.fth and private.fth for
addresses above 0x80000000. Must be unsigned.
- Call FREEZE at end of system.fth to initialize rfence.
- Fixed 0.0 F. which used to leave 0.0 on FP stack.
- Added FPICK ( n -- ) ( i*f -- i*f f[n] )
- .S now prints hex numbers as unsigned.
- Fixed internal number to text conversion for unsigned nums.
V15 - 2/15/97
* If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT
among other additions. See "pf_io.h".
* COMPARE now matches ANS STRING word set!
- Added PF_USER_INC1 and PF_USER_INC2 for optional includes
and host customization. See "pf_all.h".
- Fixed more warnings.
- Fixed >NAME and WORDS for systems with high "negative" addresses.
- Added WORDS.LIKE utility. Enter: WORDS.LIKE EMIT
- Added stack check after every word in high level interpreter.
Enter QUIT to enter high level interpreter which uses this feature.
- THROW will no longer crash if not using high level interpreter.
- Isolated all host dependencies into "pf_unix.h", "pf_win32.h",
"pf_mac.h", etc. See "pf_all.h".
- Added tests for CORE EXT, STRINGS words sets.
- Added SEARCH
- Fixed WHILE and REPEAT for multiple WHILEs.
- Fixed .( ) for empty strings.
- Fixed FATAN2 which could not compile on some systems (Linux gcc).
V14 - 12/23/96
* pforth command now requires -d before dictionary name.
Eg. pforth -dcustom.dic test.fth
* PF_USER_* now need to be defined as include file names.
* PF_USER_CHARIO now requires different functions to be defined.
See "csrc/pf_io.h".
- Moved pfDoForth() from pf_main.c to pf_core.c to simplify
file with main().

- Makefile now has target for embedded dictionary, "gmake pfemb".
V13 - 12/15/96

dictionary but also have file I/O.

- INCLUDE now aborts if file not found.
- Add +-> which allows you to add to a local variable, like +! .

dictionary saved using SAVE-FORTH.

- Fixed bug in local variables that caused problems if compilation
aborted in a word with local variables.
- Added SEE which "disassembles" Forth words. See "see.fth".
- Added PRIVATE{ which can be used to hide low level support
words. See "private.fth".

- Eliminate many warnings involving type casts and (const char *)
- Fix error recovery in dictionary creation.
- Conditionally eliminate some include files for embedded builds.
- Cleanup some test files.
V11 - 11/14/96
- Added support for AUTO.INIT and AUTO.TERM. These are called
automagically when the Forth starts and quits.

to fix hang when zero local variables.
- Align long word members in :STRUCT to avoid bus errors.
V10 - 3/21/96

- Use PF_FLOAT instead of FLOAT to avoid DOS problem.
- Add PF_HOST_DOS for compilation control.
- Shorten all long file names to fit in the 8.3 format
required by some primitive operating systems. My
apologies to those with modern computers who suffer
as a result. ;-)
