15 * Added standard version numbering, eg. "2.0.0"
16 * Add BYE-CODE variable, which will be returned to the shell when pForth exits.
17 * Set BYE-CODE when a test fails to simplify continuous integration tests.
18 * Add ANS structure support
19 * Add [DEFINED] and [UNDEFINED]
20 * Implement MSEC using usleep() to avoid busy wait.
21 * Added VERSION_CODE for software version checks.
23 * Terminal is unbuffered on posix systems
24 * Added CMAKE build, (thanks Robin Rowe)
25 * Improve unix/Makefile, moved to "platforms" folder
26 * Added GitHub actions for CI
27 * Add compiler warnings about precision loss.
28 * Improve 64-bit CELL support.
29 * Allow header and code size to be more easily controlled.
30 * Fixed definition of PF_DEFAULT_HEADER_SIZE
31 * Change license to 0BSD
32 * Added privatize to history.fth
34 ## V28 - April 24, 2018, tagged as V1.28.0 to conform to standard version format
37 * too many changes to list, see commit history (TODO add changes)
40 * fixes for MinGW build
44 * Fixed REPOSITION-FILE FILE-SIZE and FILE-POSITION.
45 They used to use single precision offset. Now use double as specified.
46 * Delete object directories in Makefile clean.
47 * Fixed "Issue 4: Filehandle remains locked upon INCLUDE error".
48 http://code.google.com/p/pforth/issues/detail?id=4&can=1
49 * Fixed scrambled HISTORY on 64-bit systems. Was using CELL+ but really needed 4 +.
50 * Fixed floating point input. Now accepts "1E" as 1.0. Was Issue #2.
51 * Fixed lots of warning and made code compatible with C89 and ANSI. Uses -pedantic.
52 * Use fseek and ftell on WIN32 instead of fseeko and ftello.
53 * Makefile is now more standard. Builds in same dir as Makefile. Uses CFLAGS etc.
54 * Add support for console IO with _WATCOMC_
55 * Internal CStringToForth and ForthStringToC now take a destination size for safety.
56 * Run units tests for CStringToForth and ForthStringToC if PF_UNIT_TESTS is defined.
60 * 64-bit support for M* UM/MOD etc by Aleksej Saushev. Thanks Aleksej!
64 * Added 64-bit CELL support contributed by Aleksej Saushev. Thanks Aleksej!
65 * Added "-x c" to Makefile CCOPTS to prevent confusion with C++
66 * Allow space after -d command line option.
67 * Restore normal tty mode if pForth dictionary loading fails.
71 * Fixed Posix IO on Mac. ?TERMINAL was always returning true.
72 * ACCCEPT now emits a space at end of line before output.
73 * Fixed RESIZE because it was returning the wrong address.
77 * Removed -v option from mkdir in build/unix/Makefile. It was not supported on FreeBSD.
78 Thank you Alexsej Saushev for reporting this.
82 * Reorganized for Google Code project.
86 * Added command line history and cursor control words.
87 * Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.
88 * Modified ACCEPT so that a line at the end of a file that does NOT have a line
89 terminator will now be processed.
90 * Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.
91 * Fixed : foo { -- } 55 ; - Was entering local frame but not exiting. Now prints error.
92 * Redefined MAKE_ID to protect it from 16 bit ints
93 * John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \
94 * Fixed float evaluation in EVALUATE in "quit.fth".
95 * Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;
99 * Fixed some compiler warnings.
103 * Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.
104 Thank you Michael Connor of Vancouver for reporting this bug.
106 * Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".
107 Thank you Jim Rosenow of Minnesota for reporting this bug.
108 * Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS
109 Thank you Jim Rosenow of Minnesota for reporting this bug.
111 * "0.0 F~" now checks actual binary encoding of floats. Before this it used to just
112 compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.
114 * Fixed definition of INPUT$ in tutorial.
115 Thank you Hampton Miller of California for reporting this bug.
117 * Added support for producing a target dictionary with a different
118 Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.
120 * PForth kernel now comes up in a mode that uses BASE for numeric input when
121 started with "-i" option. It used to always consider numeric input as HEX.
122 Initial BASE is decimal.
126 * Warn if local var name matches dictionary, : foo { count -- } ;
127 * TO -> and +-> now parse input stream. No longer use to-flag.
128 * TO -> and +-> now give error if used with non-immediate word.
129 * Added (FLITERAL) support to SEE.
130 * Aded TRACE facility for single step debugging of Forth words.
131 * Added stub for ?TERMINAL and KEY? for embedded systems.
132 * Added PF_NO_GLOBAL_INIT for no reliance on global initialization.
133 * Added PF_USER_FLOAT for customization of FP support.
134 * Added floating point to string conversion words (F.) (FS.) (FE.)
135 For example: : F. (F.) TYPE SPACE ;
136 * Reversed order that values are placed on return stack in 2>R
137 so that it matches ANS standard. 2>R is now same as SWAP >R >R
138 Thank you Leo Wong for reporting this bug.
140 * Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.
142 * FIXED memory leak in pfDoForth()
146 * Make FILL a 'C' primitive.
147 * optimized locals with (1_LOCAL@)
148 * optimized inner interpreter by 15%
149 * fix tester.fth failures
150 * Added define for PF_KEY_ECHOS which turns off echo in ACCEPT if defined.
151 * Fixed MARKER. Was equivalent to ANEW instead of proper ANS definition.
152 * Fixed saving and restoring of TIB when nesting include files.
156 * Fixed input of large floats. 0.7071234567 F. used to fail.
160 * Define PF_USER_CUSTOM if you are defining your own custom 'C' glue routines. This will ifndef the published example.
161 * Fixed warning in pf_cglue.c.
162 * Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code
163 if called when (BASE != 10), as in HEX mode.
164 * Fixed address comparisons in forget.fth and private.fth for
165 addresses above 0x80000000. Must be unsigned.
166 * Call FREEZE at end of system.fth to initialize rfence.
167 * Fixed 0.0 F. which used to leave 0.0 on FP stack.
168 * Added FPICK ( n -- ) ( i*f -- i*f f[n] )
169 * .S now prints hex numbers as unsigned.
170 * Fixed internal number to text conversion for unsigned nums.
174 * If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT among other additions. See "pf_io.h".
175 * COMPARE now matches ANS STRING word set!
176 * Added PF_USER_INC1 and PF_USER_INC2 for optional includes and host customization. See "pf_all.h".
177 * Fixed more warnings.
178 * Fixed >NAME and WORDS for systems with high "negative" addresses.
179 * Added WORDS.LIKE utility. Enter: WORDS.LIKE EMIT
180 * Added stack check after every word in high level interpreter.
181 Enter QUIT to enter high level interpreter which uses this feature.
182 * THROW will no longer crash if not using high level interpreter.
183 * Isolated all host dependencies into "pf_unix.h", "pf_win32.h",
184 "pf_mac.h", etc. See "pf_all.h".
185 * Added tests for CORE EXT, STRINGS words sets.
187 * Fixed WHILE and REPEAT for multiple WHILEs.
188 * Fixed .( ) for empty strings.
189 * Fixed FATAN2 which could not compile on some systems (Linux gcc).
192 * pforth command now requires -d before dictionary name.
193 Eg. pforth -dcustom.dic test.fth
194 * PF_USER_* now need to be defined as include file names.
195 * PF_USER_CHARIO now requires different functions to be defined.
197 * Moved pfDoForth() from pf_main.c to pf_core.c to simplify
199 * Fix build with PF_NO_INIT
200 * Makefile now has target for embedded dictionary, "gmake pfemb".
204 * Add "extern 'C' {" to pf_mem.h for C++
205 * Separate PF_STATIC_DIC from PF_NO_FILEIO so that we can use a static
206 dictionary but also have file I/O.
207 * Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.
208 * INCLUDE now aborts if file not found.
209 * Add +-> which allows you to add to a local variable, like +! .
210 * VALUE now works properly as a self fetching constant.
211 * Add CODE-SIZE and HEADERS-SIZE which lets you resize
212 dictionary saved using SAVE-FORTH.
213 * Added FILE?. Enter "FILE? THEN" to see what files THEN is defined in.
214 * Fixed bug in local variables that caused problems if compilation
215 aborted in a word with local variables.
216 * Added SEE which "disassembles" Forth words. See "see.fth".
217 * Added PRIVATE{ which can be used to hide low level support
218 words. See "private.fth".
222 * Advance pointers in pfCopyMemory() and pfSetMemory()
223 to fix PF_NO_CLIB build.

258 * improved release script and rlsMakefile
259 * added FS@ and FS! for FLPT structure members
263 * Report line number and line dump when INCLUDE aborts
264 * Abort if stack depth changes in colon definition. Helps
