1 Release History for pForth - a Portable ANS-like Forth written in ANSI 'C'
\r
3 Documentation for pForth at http://www.softsynth.com/pforth/
\r
6 - Reorganized for Google Code project.
\r
9 - Added command line history and cursor control words.
\r
10 - Sped up UM* and M* by a factor of 3. Thanks to Steve Green for suggested algorithm.
\r
11 - Modified ACCEPT so that a line at the end of a file that does NOT have a line
\r
12 terminator will now be processed.
\r
13 - Use _getch(), _putch(), and _kbhit() so that KEY, EMIT and ?TERMINAL will work on PC.
\r
14 - Fixed : foo { -- } 55 ; - was entering local frame but not exiting.
\r
15 - Redefined MAKE_ID to protect it from 16 bit ints
\r
16 - John Providenza says "If you split local variables onto 2 lines, PForth crashes." Fixed. Also allow \
\r
17 - Fixed float evaluation in EVALUATE in "quit.fth".
\r
18 - Flush register cache for ffColon and ffSemiColon to prevent stack warnings from ;
\r
21 - Fixed some compiler warnings.
\r
24 - Expand PAD for ConvertNumberToText so "-1 binary .s" doesn't crash.
\r
25 Thank you Michael Connor of Vancouver for reporting this bug.
\r
27 - Removed FDROP in REPRESENT to fix stack underflow after "0.0 F.".
\r
28 Thank you Jim Rosenow of Minnesota for reporting this bug.
\r
29 - Changed pfCharToLower to function to prevent macro expansion bugs under VXWORKS
\r
30 Thank you Jim Rosenow of Minnesota for reporting this bug.
\r
32 - "0.0 F~" now checks actual binary encoding of floats. Before this it used to just
\r
33 compare value which was incorrect. Now "0.0 -0.0 0.0 F~" returns FALSE.
\r
35 - Fixed definition of INPUT$ in tutorial.
\r
36 Thank you Hampton Miller of California for reporting this bug.
\r
38 - Added support for producing a target dictionary with a different
\r
39 Endian-ness than the host CPU. See PF_BIG_ENDIAN_DIC and PF_LITTLE_ENDIAN_DIC.
\r
41 - PForth kernel now comes up in a mode that uses BASE for numeric input when
\r
42 started with "-i" option. It used to always consider numeric input as HEX.
\r
43 Initial BASE is decimal.
\r
47 - Warn if local var name matches dictionary, : foo { count -- } ;
\r
48 - TO -> and +-> now parse input stream. No longer use to-flag.
\r
49 - TO -> and +-> now give error if used with non-immediate word.
\r
50 - Added (FLITERAL) support to SEE.
\r
51 - Aded TRACE facility for single step debugging of Forth words.
\r
52 - Added stub for ?TERMINAL and KEY? for embedded systems.
\r
53 - Added PF_NO_GLOBAL_INIT for no reliance on global initialization.
\r
54 - Added PF_USER_FLOAT for customization of FP support.
\r
55 - Added floating point to string conversion words (F.) (FS.) (FE.)
\r
56 For example: : F. (F.) TYPE SPACE ;
\r
57 - Reversed order that values are placed on return stack in 2>R
\r
58 so that it matches ANS standard. 2>R is now same as SWAP >R >R
\r
59 Thank you Leo Wong for reporting this bug.
\r
61 - Added PF_USER_INIT and PF_USER_TERM for user definable init and term calls.
\r
63 - FIXED memory leak in pfDoForth()
\r
66 - Make FILL a 'C' primitive.
\r
67 - optimized locals with (1_LOCAL@)
\r
68 - optimized inner interpreter by 15%
\r
69 - fix tester.fth failures
\r
70 - Added define for PF_KEY_ECHOS which turns off echo in ACCEPT if defined.
\r
71 - Fixed MARKER. Was equivalent to ANEW instead of proper ANS definition.
\r
72 - Fixed saving and restoring of TIB when nesting include files.
\r
75 - Fixed input of large floats. 0.7071234567 F. used to fail.
\r
78 * Define PF_USER_CUSTOM if you are defining your own custom
\r
79 'C' glue routines. This will ifndef the published example.
\r
80 - Fixed warning in pf_cglue.c.
\r
81 - Fixed SDAD in savedicd.fth. It used to generate bogus 'C' code
\r
82 if called when (BASE != 10), as in HEX mode.
\r
83 - Fixed address comparisons in forget.fth and private.fth for
\r
84 addresses above 0x80000000. Must be unsigned.
\r
85 - Call FREEZE at end of system.fth to initialize rfence.
\r
86 - Fixed 0.0 F. which used to leave 0.0 on FP stack.
\r
87 - Added FPICK ( n -- ) ( i*f -- i*f f[n] )
\r
88 - .S now prints hex numbers as unsigned.
\r
89 - Fixed internal number to text conversion for unsigned nums.
\r
92 * If you use PF_USER_FILEIO, you must now define PF_STDIN and PF_STDOUT
\r
93 among other additions. See "pf_io.h".
\r
94 * COMPARE now matches ANS STRING word set!
\r
95 - Added PF_USER_INC1 and PF_USER_INC2 for optional includes
\r
96 and host customization. See "pf_all.h".
\r
97 - Fixed more warnings.
\r
98 - Fixed >NAME and WORDS for systems with high "negative" addresses.
\r
99 - Added WORDS.LIKE utility. Enter: WORDS.LIKE EMIT
\r
100 - Added stack check after every word in high level interpreter.
\r
101 Enter QUIT to enter high level interpreter which uses this feature.
\r
102 - THROW will no longer crash if not using high level interpreter.
\r
103 - Isolated all host dependencies into "pf_unix.h", "pf_win32.h",
\r
104 "pf_mac.h", etc. See "pf_all.h".
\r
105 - Added tests for CORE EXT, STRINGS words sets.
\r
107 - Fixed WHILE and REPEAT for multiple WHILEs.
\r
108 - Fixed .( ) for empty strings.
\r
109 - Fixed FATAN2 which could not compile on some systems (Linux gcc).
\r
112 * pforth command now requires -d before dictionary name.
\r
113 Eg. pforth -dcustom.dic test.fth
\r
114 * PF_USER_* now need to be defined as include file names.
\r
115 * PF_USER_CHARIO now requires different functions to be defined.
\r
116 See "csrc/pf_io.h".
\r
117 - Moved pfDoForth() from pf_main.c to pf_core.c to simplify
\r
119 - Fix build with PF_NO_INIT
\r
120 - Makefile now has target for embedded dictionary, "gmake pfemb".
\r
123 - Add "extern 'C' {" to pf_mem.h for C++
\r
124 - Separate PF_STATIC_DIC from PF_NO_FILEIO so that we can use a static
\r
125 dictionary but also have file I/O.
\r
126 - Added PF_USER_FILEIO, PF_USER_CHARIO, PF_USER_CLIB.
\r
127 - INCLUDE now aborts if file not found.
\r
128 - Add +-> which allows you to add to a local variable, like +! .
\r
129 - VALUE now works properly as a self fetching constant.
\r
130 - Add CODE-SIZE and HEADERS-SIZE which lets you resize
\r
131 dictionary saved using SAVE-FORTH.
\r
132 - Added FILE?. Enter "FILE? THEN" to see what files THEN is defined in.
\r
133 - Fixed bug in local variables that caused problems if compilation
\r
134 aborted in a word with local variables.
\r
135 - Added SEE which "disassembles" Forth words. See "see.fth".
\r
136 - Added PRIVATE{ which can be used to hide low level support
\r
137 words. See "private.fth".
\r
140 - Advance pointers in pfCopyMemory() and pfSetMemory()
\r
141 to fix PF_NO_CLIB build.
\r
142 - Increase size of array for PF_NO_MALLOC
\r

\r
144 - Fix error recovery in dictionary creation.
\r
145 - Conditionally eliminate some include files for embedded builds.
\r
146 - Cleanup some test files.
\r
149 - Added support for AUTO.INIT and AUTO.TERM. These are called
\r
150 automagically when the Forth starts and quits.
\r
151 - Change all int to int32.
\r
152 - Changed DO LOOP to ?DO LOOP in ENDCASE and LV.MATCH
\r
153 to fix hang when zero local variables.
\r
154 - Align long word members in :STRUCT to avoid bus errors.
\r
157 - Close nested source files when INCLUDE aborts.
\r
