Changelog for brandy-1.22.1-lp155.1.7.x86_64.rpm :

* Fri Sep 20 2019 Luigi Baldoni - Update to version 1.22.1
* Make the old BASIC I-IV compatible integer mathematics available via a run-time switchable setting.
* Integer addition and subtraction will now return integer if it fits, else a float. (Legacy mode: unchanged, will always return an int, with wraparound).
* Integer multiplication follows new code path at all times, old int-only implementation didn\'t match any Acorn BBC BASIC version and is thus a bug.
* Fixed stack pointer leak bug.
* Fixed behaviour setting HIMEM immediately after LOADing a file
* SYS \"Brandy_GetVideoDriver\" extended, returns MODE 7 framebuffer base in R4.
* RISC OS style sound working. MANY thanks to David Hawes.
* Separate out segfault memory error to its own error message.
* Fix pass-back of strings from SYS on 64-bit systems.
* Fix sound with volume = 0 (Thanks David Hawes)
* Sound updates in StringLib family (Thanks David Hawes)
* Bug fix for VAL - it should ONLY handle decimal numbers (not hex or binary)
* Fix flood fill (it just didn\'t work right), new implementation is however quite memory hungry and recursive.
* Signal handler updated, longjmps now use siglongjmp. check_read() and check_write() no longer required. Note this also allows a program to trample on the BASIC stack.
* Many keyboard updates (Thanks Jonathan Harston) Version 1.22.0:
* Change identifier to BASIC VI (which is BASIC V with 64-bit FP maths, which is what Brandy has always done)
*
*SPOOL and
*SPOOLON implemented.
* Fix integer overflows when converting from floats.
* Fix intermittent crash when execution hits a DEF statement.
* Added a run-time switchable setting for INT() whether it can process numbers out of range of a 32-bit int data type. Default is off.
* Implement the AUTO command. version 1.21.21:
* Centisecond timer polling hived off to its own thread, as polling it every command iteration for ESCAPE checking was expensive.
* Program execution now much faster than before, and slightly faster again when ESCAPE is disabled via
*FX200.
* Renamed some #DEFINEs as they were colliding on a new gcc on Cygwin.
* ESCAPE on VDU14 paged mode now works.
* INKEY no longer swallows a non-matching keypress.
* Some more OS SWIs implemented (the Snow demo from RISC OS Pico for RasPi now runs unmodified).
* Optionally allow an unselectable MODE to be substituted with another one instead of reporting \"Screen mode is not available\".
* Some more Raspberry Pi GPIO stuff, including recognising most RISC OS GPIO module SWI names, and implementing a few.
* Unsupported colour depths are mapped to 24-bit (previously was 8-bit), so a program asking for a 15-bit mode will be able to draw colours as largely intended.
* Extended OSBYTE 42 to allow an immediate refresh - SYS6,42,16 may be faster than parsing \"
*REFRESH\" for anything time-critical (and obvious functionality that was missing from the interface)
* Quotes are stripped if appropriate from
*ScreenSave and
* ScreenLoad. They remain optional for filenames which include spaces. version 1.21.20:
* Improved CIRCLE FILL and ELLIPSE FILL routines.
* Added -v CLI option - thanks TheBrokenRail AATT Github.
* Reworked graphics window clipping, as it was completely broken.
* Fixed string return values from SWI calls, hopefully they will not break on 64-bit systems
* Added SWI \"Brandy_GetVideoDriver\" as a wrapper for SDL_VideoDriverName, additionally returns \"no_sdl\" for non-SDL builds
* Extended SWI \"Brandy_Version\" to also return host OS and whether or not it\'s an SDL build.
* Sat Mar 02 2019 Luigi Baldoni - Update to version 1.21.19
* Hopefully fixed the spurious cursor remnants.
* Ellipses with shears now implemented, PLOT &C5 and PLOT &CD now work correctly (fill implementation could possibly be improved). Other variants to be tested.
* ELLIPSE [FILL] command with non-zero angle now supported.
* MODE 7: Update screen on WAIT-delay, and flash continues during WAIT.
* MODE 7: Increase display accuracy at the expense of performance, switchable via VDU23,18,1,x| - bit 0 is also now implemented.
* MODE 7:
*REFRESH now does the right thing.
* WAIT can now be interrupted with ESCAPE.
* Invocation behaviour change: brandy now assumes - quit instead of -chain.
* Support for shrouded BASIC programs, examples/shroud will shroud a program hiding the source code. It is itself shrouded. A shrouded program cannot be LOADed or CHAINed, and can only be invoked from the command line.
* Makefile and code improvement contributions from ccawley2011 AATT github.
* Corrected behaviour of EOF#0, BPUT#0, BGET#0 etc, thanks dhg2 AATT Stardot.
*
*EXEC implemented. Idea from Richard Russell.
*
*-commands that call out to external commands from Windows no longer cause a CMD window to open, also fixing the \"stuck key\" problem associated with this. Thanks to Richard Russell for the guidance here. version V1.21.18
*
*SHOW implemented (JGHarston)
* Bug fix for DEL in text-only builds (JGHarston)
* Limit
*WinTitle to SDL and UNIX builds - it\'s a no-op otherwise.
* MODE 7 scrolling text fix
* MODE 135 now selects MODE 7.
* Fix VDU20 for text-mode UNIX build
* Top-level makefiles now read BRANDY_BUILD_FLAGS environment variable for additional build flags
* New keyboard handler (JGHarston) - add -DNEWKBD to makefile to CFLAGS or define BRANDY_BUILD_FLAGS=-DNEWKBD in your shell environment to use. version V1.21.17
* Fix memory leak in MODE change
* Fix Filled Rectangles and CLG with GCOL actions, previously implemented and rather promptly broken.
* Fixed Flash on Mode 7 on 64-bit machines.
* Fixed Escape on 32-bit machines.
* Improved INKEY(negative) handling and other keyboard bugs, thank you JGHarston.
* Fix reading strings from DATA with included quote marks.
* Fix LSL (<<), ASR (>>) and LSR (>>>) to replicate RISC OS behaviour.
* VDU19 palette changes now update the screen immediately. Also, now has no effect in MODE 7.
* Mouse display behaviour changed - if fullscreen mode enabled, mouse is off upon mode change or startup; if windowed, mouse is on.
* Telstar client now includes NXtel, and a new, more robust, mechanism of calculating high-bit escaped characters, as NXtel did it differently to Telstar or CCl4. version V1.21.16
* Added auto-sensing support for the Raspberry Pi\'s GPIO interface, with memory-mapped I/O and SYS calls. While the calls are recognised on all builds, it\'s only active on the Raspberry Pi.
* Bug fix (regression): LIST in text builds would error after one line.
* Adjust graphsdl.c:buff_convex_poly bounds checking to allow off-screen drawing (we limit this elsewhere). For example, triangles drawn offscreen. will now appear to be chopped off, rather than squashed into the screen.
* Bug fix for out-of-bounds array scribbling when off screen.
* Code refactor - SYS calls are now (with a few exceptions) in their own file.
* Performance improvements to Mode 7, and fix rendering bug when ESCAPE was disabled.
* Telstar client now includes Authentic mode, where a delay is added to each character rendering to simulate (approximately) a 1200baud modem.
* Implemented AND=, OR=, EOR=, MOD= and DIV= from BB4W/BBCSDL and JGH\'s ARM BBC BASIC Plus. version V1.21.15
* Bug fix: Setting
*KEY15 scribbled outside array bounds.
* Bug fix: Erroneously trimming a string introduced in V1.21.8.
* Improvement: In networking code, move WSAStartup (MinGW) to init, if this fails, disable networking.
* Enabled VDU14/15 scroll paging. Note, by default Brandy uses CTRL-N for accessing the next line in the command line history (along with CTRL-P for previous line). OSBYTE 44 with x=0 disables this, so CTRL-N will send the VDU14 code, CTRL-P will send the VDU16 (CLG) code. (CTRL-O will always send the VDU15 code)
* Enabled VDU23,16; currently bits other than 3 are observed. This sets the scroll protect mode, X and Y cursor movement and whether the screen is overprinted or scrolled when the Y limit is reached, and whether VDU5 mode linewraps. (Bit 3, making Y horizontal and X vertical is NOT supported.) Default value is 1 (
*CONFIGURE NOSCROLL on RISC OS or BBC Master) and the VDU mode when RISC OS Desktop is running (or in a single tasking state from F12 or Exit) regardless of Scroll/NoScroll configuration setting.
* Fix compiler warnings for MinGW - and allow DOS-type commands to return their output to the SDL window (so
*dir works for example).
* Flush SDL queue on INKEY and MOUSE reads, otherwise events start to get missed (bonus point: Close window icon is more responsive.)
* LISTing a program now stops on ESCAPE.
* Code cleanup part 1: Identify functions that can be declared static.
* Code cleanup part 2: Remove static functions that are never called from anywhere.
* Updated some of the documentation to reflect the changes introduced in Matrix Brandy.
* Improved the Mode 7 appearance (thanks to Risc OS 5!) - see docs/Mode7.txt- Dropped brandy-flags.patch (no longer necessary)
* Fri Sep 28 2018 Luigi Baldoni - Update to version 1.21.14
* ChangeLog layout change: Most recent release first.
* Similar to the GET fix in V1.21.11, the same problem of spurious zero returns was occurring with INKEY(delay). This is now fixed.
* Bug fix for CLS when a text window is active, the cursor was not being homed.
* Bug fix for VDU28 text windows where bottom or right were out of range.
* Bug fix for text cursor appearing inappropriately in VDU5 mode.
* Fix more compiler warnings - thanks bakoulis and Coeus at Stardot for highlighting where their compilers were warning where mine wasn\'t, and for suggesting a fix.
* PLOT actions redirected to new primitives that support GCOL action codes, both foreground and background codes work.
* Behaviour of DELETE (and VDU127) is corrected.
* WAIT (with no parameters) to wait for VSYNC implemented, as far as is possible in SDL.
* 24-bit colour support enabled.
* MOUSE TO implemented.
* Code clean-up, \"text mode\" in SDL screen removed. It\'s never been used since the appearance of MODEs 3 and 6 were corrected.
* BrandyApp compilation on Linux changed to using a library to simplify the build process.
* Telstar client updated, enhancements from gARetH baBB - thank you!- Refreshed brandy-flags.patch
* Fri Sep 14 2018 aloisioAATTgmx.com- Update to version 1.21.13
* Rework temp file bits to use mkstemp instead of tmpnam.
* Reinstated MODE 7 width setting via VDU23,18,255 (from 1.21.7). Note that it does not resize the window, and re-selecting MODE 7 restores the default glyph width of 16.
* Add
*ScreenSave - saves the displayed screen as a Windows Bitmap file
* Add
*ScreenLoad - Loads the screen into the currently selected display bank for VDU writes
* Initial makefile for SDL on MinGW. Much testing required.
* New Mode 7 demo. Some Prestel graphics, and images from the edit.tf online Teletext page editor. Unlike the BBCSDL demo this embeds the data in the program itself. Apart from pressing R to reveal it isn\'t Brandy-specific.
* New Telstar client. Screen updates seem faster, with more convincing double-height.
* Sun Sep 02 2018 aloisioAATTgmx.com- Update to version V1.21.12
* Bug fixed: Closed file warning clobbered ERR value. Thanks to dhg2 AATT Stardot for highlighting this one.
* Bug fixed: OSWORD via &FFF1 wasn\'t returning the A register. Thanks to luigino AATT Github for highlighting this.
* Bugs fixed: Multiple compiler warnings when compiled with - Wall, and static analysis.
* Bug fixed: Text-only builds no longer complain about \"Unsupported Basic V feature\" when using WAIT.
* Brought the text-only builds up to date, brought makefile.text back to top level.
*
*WinTitle now works on text-only builds using XTerm control codes.
* Changing screen mode no longer clears FULLSCREEN.
* Expanded OSBYTE 42 to get or set fullscreen state, and fixed an off-by-one error in returning Refresh state.
* RPM SPEC file now builds text builds as well as the graphical build, the resulting RPM includes all three builds (graphical, text, simple-text).- Dropped brandy-no_return_in_nonvoid.patch (fixed upstream)
* Fri Aug 24 2018 aloisioAATTgmx.com- Update to version 1.21.11
* Bug fixed: POINT(x,y) should return the logical mode-specific colour number rather than an RGB value.
* Bug fixed: GET returning 0 and key value for some keys
* Bug fixed: Crash when ON ERROR handler invoked in program run using CHAIN at immediate mode
* Initial structure in place for OSWORD; OSWORD 10 implemented including BBC-style call to &FFF1 and SWI &07.
* OSBYTEs 134 and 165 implemented. As Brandy doesn\'t have the Acorn-style editing cursor, these two function identically.
* OSBYTEs 106 and 135 implemented partially (135 only complete in MODE 7), 106 can only turn the pointer on or off.
* Invocation behaviour change: If BASIC program starts with # as the first character, assume we have a shell-compatible start line that is invoking Brandy. In this case, if the program is started on the Linux command line as a parameter to Brandy, it will exit upon program completion instead of returning to immediate mode (as if -quit was set on the command line). This also means a BASIC program can be made executable and will run when run as a script, and Brandy will exit upon completion.- Added brandy-no_return_in_nonvoid.patch
* Tue Aug 21 2018 aloisioAATTgmx.com- Update to version V1.21.10
*
*REFRESH now follows BB4W/BBCSDL behaviour, with extension
* REFRESH ONERROR which uses the behaviour from V1.21.9 (disabled, re-enabled on error)
* COLOUR r,g,b and GCOL r,g,b now behaves properly when values > 255 supplied.
* OSBYTE 42 implemented to allow BASIC and user programs to get and set REFRESH state, allowing access while maintaining logical separation of language and MOS.
* OSBYTEs 40 and 41 implmented for fine-tuning the ESCAPE polling. OSBYTE 40 with X=0 resets to default.
* Screen banks enabled, set at compile time (default is 4). Use with OSBYTE 112 and 113. Not enabled for MODE 7.
* OSBYTEs 20 and 25 implemented for resetting the system font.
* BB4W/BBCSDL\'s VDU23,22 implemented to a degree, defining MODE 126.
* MODEs 3 and 6 now have black bars when background colour used.
* RISC OS 3.5-style MODE commands will define a new mode (126) if a previously defined mode is not available. The extended RISC OS 5.x format is not supported.
*
*NewMode extended to allow input of X and Y eigen factors, used internally by the MODE \"string\" format.
* Initial SWI support, currently only a few SWIs are supported. No support for external modules, all supported SWIs are part of the MOS code.
* examples/teklib updated - this pre-dates SDL support for Brandy, using Tek to provide an element of graphics. This has been updated to use OSBYTE 43 to send characters to the controlling terminal, so if run from an xterm, the old Tek demos once again run correctly as intended.
* Fri Aug 10 2018 aloisioAATTgmx.com- Update to version 1.21.9
* Implement
*REFRESH (based on RTR\'s BB4W/BBCSDL).
* Possible divergence: An error condition will re-enable Refresh.
* INKEY implementation improved, we now also pick up mouse keys.
* ESCAPE now works within the SDL window.
*FX229 also implemented to disable or enable ESCAPE.
* Display warnings/help for
*NewMode
* Improve rendering of MODEs 3 and 6.
* MODE 7 flash now locked to the centisecond timer.
* MODE 7 screeen memory: An earlier omission meant only the byte pointer functions worked, now word pointer functions also work.
* Tue Aug 07 2018 aloisioAATTgmx.com- Update to version 1.21.8- Dropped brandy-bounds_check_token_arrays.patch and brandy-bounds_check_token_arrays.patch (merged upstream)
* Fri Aug 03 2018 aloisioAATTgmx.com- Backported brandy-use_getaddrinfo.patch to fix the gethostbyname() warning
* Fri Aug 03 2018 aloisioAATTgmx.com- Backported brandy-bounds_check_token_arrays.patch to fix array overflow warning
* Fri Aug 03 2018 aloisioAATTgmx.com- Initial package (1.21.7)
