User-visible changes between 0.3.0 and 0.4.0: |
|
|
|
Operating environment: |
|
|
|
Path handling: "." at the start of the path represents the directory |
|
the nearest enclosing file resides in (if there is none: the working |
|
directory). "~+" indicates the working directory. The default path |
|
now has "." in front. |
|
gforth and gforthmi is now more GNU standards compliant (wrt |
|
command-line options). |
|
New command-line-option: --die-on-signal |
|
Errors are now directed to stderr. |
|
Stdout is now unbuffered, if it is a tty. |
|
User input device redirection (for filters) is now possible. |
|
|
|
Ports: |
|
|
|
Now runs on IRIX (and other MIPS-based systems without linker-flag -d). |
|
Direct threading now works on PowerPC (20% speedup on 604e). |
|
Better support for m68k (thanks to Andreas Schwab and Jorge Acereda). |
|
It is possible to create executables that contain the image (for |
|
non-OS systems). |
|
|
|
Added a lot of embedded control (EC) stuff. Supported controllers and |
|
small CPUs are Siemens C16x, 8086, 6502, Mixed-Mode's FPGA MISC, Bernd Paysan's |
|
4stack processor. Not finished: ShBoom alias PSC1000, H8, AVR. |
|
|
|
New, changed, and removed words: |
|
|
|
Renamed F0 to FP0 (avoids unexpected behaviour in hex), added aliases |
|
SP0, RP0, LP0 (recommended for future use) for S0, R0, L0. |
|
Renamed PARSE-WORD into SWORD (PARSE-WORD is used with the meaning of |
|
NAME in OpenBoot and dpans6 A.6.2.2008) |
|
Added FPICK (suggested by Julian Noble). |
|
Added EXCEPTION. |
|
S" gforth" ENVIRONMENT? now produces the version-string. |
|
Changed representation of types in struct package, and correspondingly |
|
changed names. |
|
|
|
Miscellaneous: |
|
|
|
Plain text documentation is now available in doc/gforth.txt. |
|
Documentation improvements. |
|
Wordlist structure changed. |
|
Added mini-oof. |
|
Reorganized files: added directories and reorganized many files into |
|
them; renamed files into 8.3 format to work with completely broken |
|
systems (but there are again some files that won't work there). |
|
Bug fixes. |
|
Various changes without log information only known as mega-patches. |
|
Cross compiler now also supports compilation only for undefined or forward |
|
referenced words. Plugins to support some native code generation |
|
(for PSC1000). |
|
More files in the compat library. |
|
|
|
|
|
|
|
User-visible changes between 0.2.1 and 0.3.0: |
|
|
|
Stack overflow detection by memory protection on most systems |
|
(allocation with mmap). |
|
gforth.fi is now fully relocatable. |
|
fully relocatable images are now easier to create. |
|
added primitives K and UNDER+. |
|
Win32 support. |
|
Improved support for embedded controllers and other deprived environments. |
|
some bug fixes. |
|
added concept index; other documentation improvements. |

|
Changed popen and pclose to open-pipe and close-pipe. |
|
Added form, rows, and cols. |
|
Added compat/ directory containing ANS implementations of Gforth features. |
|
added primitives EMIT-FILE, STDOUT, STDERR; EMIT and TYPE now work |
|
through file words (and are redirectable). |
|
Support architectures with buggy long longs (alpha-dec-osf). |
