| 100 : | |||
| 101 : | anton | 1.18 | User-visible changes between 0.6.1 and 0.6.2: |
| 102 : | |||
| 103 : | anton | 1.19 | Bug fixes (in particular, gforth-0.6.2 compiles with gcc-3.3) |
| 104 : | New words: LATEST, LATESTXT (LASTXT deprecated) | ||
| 105 : | Operating environment: Added optional support for a C interface built | ||
| 106 : | on the ffcall libraries (more portable and powerful than the old | ||
| 107 : | one, but still not documented). To use it, the ffcall libraries | ||
| 108 : | have to be installed before building Gforth (see INSTALL). | ||
| 109 : | Miscellaneous: Gforth-fast now uses static superinstructions (some | ||
| 110 : | speedup on some platforms); generally this is transparent (apart | ||
| 111 : | from the speedup), but there are lots of command-line options for | ||
| 112 : | controlling the static superinstruction generation. | ||
| 113 : | anton | 1.18 | |
| 114 : | |||
| 115 : | anton | 1.16 | User-visible changes between 0.6.0 and 0.6.1: |

| 118 : | |||
| 119 : | |||
| 120 : | anton | 1.9 | User-visible changes between 0.5.0 and 0.6.0: |
| 121 : | |||
| 122 : | anton | 1.14 | Changes in behaviour: |
| 123 : | anton | 1.10 | |
| 124 : | anton | 1.14 | S": interpreted use now ALLOCATEs the string (they live until BYE). |
| 125 : | Long word names (512MB on 32-bit systems) are now supported (change to | ||
| 126 : | the header format). | ||
| 127 : | New threaded code execution method: primitive-centric (allows the | ||
| 128 : | following), hybrid direct/indirect threaded (easier portability), | ||
| 129 : | with dynamic superinstructions (typical speedup on Athlon: factor | ||
| 130 : | 2). New engine gforth-itc for dealing with some potential | ||
| 131 : | anton | 1.16 | backwards-compatibility problems (see "Direct or Indirect Threaded?" |
| 132 : | in the manual). | ||
| 133 : | anton | 1.14 | |
| 134 : | Operating environment: | ||
| 135 : | |||
| 136 : | Default dictionary size is now 4MB. | ||
| 137 : | anton | 1.10 | Large file support on OSs that support them (i.e., files with more |
| 138 : | than 2GB on 32-bit machines). | ||
| 139 : | anton | 1.15 | Gforth can now deal well with broken pipes in most situations. |
| 140 : | anton | 1.10 | vi tags files can be built with tags.fs (usage like etags.fs). |
| 141 : | anton | 1.14 | gforth.el mostly rewritten. |
| 142 : | New image file format. | ||
| 143 : | anton | 1.10 | |
| 144 : | anton | 1.14 | New words: |
| 145 : | anton | 1.10 | |
| 146 : | anton | 1.14 | Keyboard input: EDIT-LINE K-PRIOR K-NEXT K-DELETE |
| 147 : | File input: SLURP-FILE SLURP-FID | ||
| 148 : | Programming tools: ID. .ID WORDLIST-WORDS SIMPLE-SEE | ||
| 149 : | Conditional execution: [DEFINED] [UNDEFINED] | ||
| 150 : | anton | 1.17 | Defining Words: CONST-DOES> ]] |
| 151 : | anton | 1.14 | Input stream: PARSE-WORD EXECUTE-PARSING EXECUTE-PARSING-FILE |
| 152 : | String comparison: STR= STR< STRING-PREFIX? | ||
| 153 : | String literals: S\" .\" \"-PARSE | ||
| 154 : | Floating point output: F.RDP F>STR-RDP F>BUF-RDP | ||
| 155 : | anton | 1.9 | |
| 156 : | anton | 1.14 | Miscellaneous: |
| 157 : | anton | 1.9 | |
| 158 : | Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the | ||
| 159 : | new capabilities in prims (e.g., automatic handling of the return | ||
| 160 : | stack and instruction stream). | ||
| 161 : | anton | 1.10 | |
| 162 : | anton | 1.9 | |
| 163 : | anton | 1.8 | User-visible changes between 0.4.0 and 0.5.0: |
| 164 : | |||
| 165 : | Changes in behaviour: | ||
| 166 : | |||
| 167 : | There are now two engines: the fast engine (gforth-fast) is at least | ||
| 168 : | as fast as gforth in earlier releases; the debugging engine (gforth) | ||
| 169 : | supports precise backtracing for signals (e.g., illegal memory | ||
| 170 : | access), but is slower by a factor of 1-2. | ||
| 171 : | Block files now start at block 0 by default (instead of block 1). If | ||
| 172 : | you have block files around, prepend 1024 bytes to convert them, or | ||
| 173 : | do a "1 OFFSET !" to establish the old behaviour. | ||
| 174 : | Gforth now does not translate newlines to LFs on reading. Instead, | ||
| 175 : | READ-LINE now interprets LF, CR, and CRLF as newlines. Newlines on | ||
| 176 : | output are in the OSs favourite format. | ||
| 177 : | SEE now disassembles primitives (or hex-DUMPs the code if no | ||
| 178 : | disassembler is available). | ||
| 179 : | >HEAD (aka >NAME) now returns 0 (instead of the nt of ???) on failure. | ||
| 180 : | Syntax of prim changed: stack effects are now surrounded by | ||
| 181 : | parentheses, tabs are insignificant. | ||
| 182 : | |||
| 183 : | Operating environment: | ||
| 184 : | |||
| 185 : | Gforth now produces a backtrace when catching an exception. | ||
| 186 : | On platforms supporting the Unix 98 SA_SIGINFO semantics, you get more | ||
| 187 : | precise error reports for SIGSEGV and SIGFPE (e.g., "stack | ||
| 188 : | underflow" instead of "Invalid memory address"). | ||
| 189 : | Gforth now produces exit code 1 if there is an error (i.e., an | ||
| 190 : | uncaught THROW) in batch processing. | ||
| 191 : | You can use "gforthmi --application ..." to build an image that | ||
| 192 : | processes the whole command-line when invoked directly (instead of | ||
| 193 : | through gforth -i). | ||
| 194 : | |||
| 195 : | Ports: | ||
| 196 : | |||
| 197 : | AIX. | ||
| 198 : | 20% speedup on 604e under powerpc-unknown-linux-gnu, | ||
| 199 : | 19%-29% speedup on Celeron with gcc-2.95. | ||
| 200 : | |||
| 201 : | New words: | ||
| 202 : | |||
| 203 : | Missing ANS Forth words: EKEY EKEY? EKEY>CHAR | ||
| 204 : | Timing words: CPUTIME UTIME | ||
| 205 : | Vector arithmetic: V* FAXPY | ||
| 206 : | FP comparison: F~ABS F~REL | ||
| 207 : | Deferred words: <IS> [IS] | ||
| 208 : | Nested number output: <<# #>> | ||
| 209 : | Exception handling: TRY RECOVER ENDTRY | ||
| 210 : | Directory handling: OPEN-DIR READ-DIR CLOSE-DIR FILENAME-MATCH | ||
| 211 : | Other: ]L PUSH-ORDER | ||
| 212 : | |||
| 213 : | Miscellaneous: | ||
| 214 : | |||
| 215 : | Significant extensions to the manual (added an introduction, among | ||
| 216 : | other things), many of them due to a new team member: Neal Crook. | ||
| 217 : | Added assemblers and disassemblers for 386, Alpha, MIPS (thanks to | ||
| 218 : | contributions by Andrew McKewan, Bernd Thallner, and Christian | ||
| 219 : | Pirker). Contributions of assemblers and disassemblers for other | ||
| 220 : | architectures are welcome. | ||
| 221 : | |||
| 222 : | |||
| 223 : | anton | 1.6 | User-visible changes between 0.3.0 and 0.4.0: |
| 224 : | |||
| 225 : | Operating environment: | ||
| 226 : | |||
| 227 : | Path handling: "." at the start of the path represents the directory | ||
| 228 : | the nearest enclosing file resides in (if there is none: the working | ||
| 229 : | directory). "~+" indicates the working directory. The default path | ||
| 230 : | now has "." in front. | ||
| 231 : | gforth and gforthmi is now more GNU standards compliant (wrt | ||
| 232 : | command-line options). | ||
| 233 : | New command-line-option: --die-on-signal | ||
| 234 : | Errors are now directed to stderr. | ||
| 235 : | Stdout is now unbuffered, if it is a tty. | ||
| 236 : | User input device redirection (for filters) is now possible. | ||
| 237 : | |||
| 238 : | Ports: | ||
| 239 : | |||
| 240 : | Now runs on IRIX (and other MIPS-based systems without linker-flag -d). | ||
| 241 : | Direct threading now works on PowerPC (20% speedup on 604e). | ||
| 242 : | Better support for m68k (thanks to Andreas Schwab and Jorge Acereda). | ||
| 243 : | It is possible to create executables that contain the image (for | ||
| 244 : | non-OS systems). | ||
| 245 : | pazsan | 1.7 | |
| 246 : | Added a lot of embedded control (EC) stuff. Supported controllers and | ||
| 247 : | small CPUs are Siemens C16x, 8086, 6502, Mixed-Mode's FPGA MISC, Bernd Paysan's | ||
| 248 : | 4stack processor. Not finished: ShBoom alias PSC1000, H8, AVR. | ||
| 249 : | anton | 1.6 | |
| 250 : | New, changed, and removed words: | ||
| 251 : | |||
| 252 : | Renamed F0 to FP0 (avoids unexpected behaviour in hex), added aliases | ||
| 253 : | SP0, RP0, LP0 (recommended for future use) for S0, R0, L0. | ||
| 254 : | Renamed PARSE-WORD into SWORD (PARSE-WORD is used with the meaning of | ||
| 255 : | NAME in OpenBoot and dpans6 A.6.2.2008) | ||
| 256 : | Added FPICK (suggested by Julian Noble). | ||
| 257 : | Added EXCEPTION. | ||
| 258 : | S" gforth" ENVIRONMENT? now produces the version-string. | ||
| 259 : | Changed representation of types in struct package, and correspondingly | ||
| 260 : | changed names. | ||
| 261 : | |||
| 262 : | Miscellaneous: | ||
| 263 : | |||
| 264 : | Plain text documentation is now available in doc/gforth.txt. | ||
| 265 : | Documentation improvements. | ||
| 266 : | Wordlist structure changed. | ||
| 267 : | Added mini-oof. | ||
| 268 : | Reorganized files: added directories and reorganized many files into | ||
| 269 : | them; renamed files into 8.3 format to work with completely broken | ||
| 270 : | systems (but there are again some files that won't work there). | ||
| 271 : | Bug fixes. | ||
| 272 : | Various changes without log information only known as mega-patches. | ||
| 273 : | pazsan | 1.7 | Cross compiler now also supports compilation only for undefined or forward |
| 274 : | referenced words. Plugins to support some native code generation | ||
| 275 : | (for PSC1000). | ||
| 276 : | anton | 1.6 | More files in the compat library. |
| 277 : | |||
| 278 : | |||
| 279 : | |||
| 280 : | anton | 1.5 | User-visible changes between 0.2.1 and 0.3.0: |
| 281 : | |||
| 282 : | Stack overflow detection by memory protection on most systems | ||
| 283 : | (allocation with mmap). | ||
| 284 : | gforth.fi is now fully relocatable. | ||
| 285 : | fully relocatable images are now easier to create. | ||
| 286 : | added primitives K and UNDER+. | ||
| 287 : | Win32 support. | ||
| 288 : | Improved support for embedded controllers and other deprived environments. | ||

| 299 : | |||
| 300 : | anton | 1.5 | User-visible changes between 0.1beta and 0.2.0: |
| 301 : | anton | 1.1 | |
| 302 : | anton | 1.3 | Portability and Installation: |
| 303 : | |||
| 304 : | anton | 1.1 | Support architectures with buggy long longs (alpha-dec-osf). |
| 305 : | anton | 1.3 | Better support for DOS and other non-Unix systems. |
| 306 : | anton | 1.1 | Size changes through the command line are passed to the image (and |
| 307 : | saved with savesystem); the preamble specifies an interpreter and is | ||
| 308 : | propagated by save-system. | ||
| 309 : | anton | 1.3 | |
| 310 : | Tools: | ||
| 311 : | |||
| 312 : | Improved etags support. | ||
| 313 : | more.fs allows output paging. | ||
| 314 : | Added compat/ directory containing ANS implementations of Gforth features. | ||
| 315 : | Added tiny multitasker (tasker.fs). | ||
| 316 : | Added two alternatives for object-oriented programming: oof.fs, objects.fs. | ||
| 317 : | Added ans-report.fs (reports which words are used from which wordset). | ||
| 318 : | |||
| 319 : | New words: | ||
| 320 : | |||
| 321 : | Changed POPEN and PCLOSE to OPEN-PIPE and CLOSE-PIPE. | ||
| 322 : | Added FORM, ROWS, and COLS. | ||

| 325 : | added POSTPONE,. | ||
| 326 : | Added the ability to combine arbitrary interpretation and compilation | ||
| 327 : | semantics (INTERPRET/COMPILE:); state-smart words were generally | ||
| 328 : | rewritten to use that mechanism. | ||
| 329 : | |||
| 330 : | Changes to existing words: | ||
| 331 : | |||
| 332 : | EMIT and TYPE now work through file words (and are redirectable). | ||
| 333 : | anton | 1.1 | HEADER now stores the compilation wordlist in the header and REVEAL |
| 334 : | reveals into that wordlist. | ||
| 335 : | anton | 1.3 | changed behaviour of SYSTEM (no longer returns wretval, but puts it in |
| 336 : | $?) added (SYSTEM) ( c_addr u -- wretval wior ). | ||
