- *** Desk 3.10 ***
-
-
-
-
- 22 Jan 1997
- Fixed bug in Desk_Filing_OpenDir2's treatment of wildcard - set to NULL
- so can be freed after error. Also uses Desk_strdup. Removed Filing's
- MALLOC and FREE macros - uses Desk_DeskMem_ now.
-
- Fixed undocumented bug in Wimp_PlotIcon veneer. When not in redraw loop,
- r4 and r5 specify the graphics origin. Now sets these to 0. Added
- Desk_Wimp_PlotIcon2( Desk_icon_block* fakeicon, int xorigin, int
- yorigin) to allow for this usage.
-
-
-
- 20 Jan 1997
-
- Added Desk_Debug_RedirectToFilename, only implemented in uniqfile at the
- moment.
-
- Added Save2 library - uses Export and Dialog2 to provide save windows.
-
-
- 17 Jan 1997
-
- Added Desk_Window_ToggleShow
-
-
- 15 Jan 1997
- Changed Screen to always find new mode variables - under RO3.50 and
- later, mode variable can be same even if mode has changed (it's a
- pointer to a block of memory).
-
-

- Fixed bug in Desk_Filing_OpenDir2() - was malloc(strlen()), strcpy...
-
- 09 Jan 1997

- converting source from using DeskLib to Desk. Needs the RISC OS port of
- sed.
-
-
- 07 Jan 1997
- Adding support for interactive help to Menu2. Menu2 Desk_Menu2_Create2

-
-
- 05 Dec 1996
- Fixed bug in Desk_Icon_FileIcon - was using "Desk_file_%3x" instead of

- filename suffix correctly.
-
-
- 21 Oct 1996

-
- *** 11 Sep 1996 Desk 3.00beta ***
-
-
- Changes between DeskLib 2.30x betas and release 3.00 beta of Desk:
- ——————————————————————————————————————————————————————————————————
-
- Menu2
- Desk_Menu2_Create now requires a (possibly NULL) pointer to a
- function to call whenever a menu is closed in any way.
-
- LinkList
- Desk_LinkList_InsertBefore/After now work if pos is NULL.
-
- Core
- Desk_os_error is now typedef-ed to _kernel_oserror if compilation is
- with Acorn compiler. This allows the two types to be used interchangably
- which is sometimes very useful.
- New boolean typedef enum 'Desk_bool' is used wherever DeskLib's BOOL was
- used.
- Desk__MODULE_CLIENT is expected to be predefined when compiling with cc
- -zm.
-
- BackTrace
- New library for walking the stack. Very useful when debugging...
-
- Jump
- Macros/functions involving setjmp and longjmp, for use by the Error2
- library. These should be compatible with SDLS, but I haven't tried this.
-
- Error2
- All support for handling errors. All of Desk uses this library when an
- error occurs.
-
- DynamArea
- Simple management of dynamic areas - allows you to easily create/resize
- etc, without worrying about the rather unhelpful behaviour of the
- underlying SWIs - DynamArea keeps track of the actual size of the area
- etc.
-
- Event
- Added Desk_Event_MessagesClaim and Desk_Event_MessagesRelease - simply
- claim/release all three message types in one go.
-
- Import2
- Provides general support for exporting data using either file or ram
- transfer.
-
- MsgTrans
- Added functions for finding the size of a message after substitution,
- looking up into Desk_deskmem_buffer's, opening a file with the system
- info stored in RMA.
-
- KernelSWIs
- Added functions for convenient reading of a system variable.
- Added functions for reading/writing CMOS.
-
- File
- Removed the old system which used a global variable to store the last
- error returned.
- Added a few extra functions.
-
- Filing
- Added Desk_Filing_CompareDates.
-
- DeskMem
- New library which provides standard veneers for malloc et al, which
- raise errors instead of returning 0. Uses function pointers to point to
- malloc, realloc etc, which can be changed to point to user-supplied ones
- (eg if you want all memory to be in a dynamic area)
- Added Desk_deskmem_buffer and associated support functions, which
- provide easy-to-use buffers which are always multiples of an initial
- size, to try to prevent fragmentation.
-
- Export
- Handles export of data using file or ram transfer.
-
-
- Many functions which previously returned an (os_error*) have been
- changed to return void, and raise an error if something goes wrong. Eg
- all the Wimp SWI veneers.
-
-

- ********************************************************************
-
- DeskLib betas 2.3x
- ——————————————————
-
- Updates between DeskLib beta versions since version 2.30
-
-
-
- 13 May 1996
-
- Filing now treats images as directories.
-
-
- 09 May 1996
-
- Event__ExitFunction now sets taskhandle to 0 after calling
- Wimp_CloseDown.
-
- Error_Report functions now output backtrace to stderr in debug builds.
-
-
-
- 08 May 1996
-
- Module verion now compiled with -ff to remove embedded fn names. Added
- DL_M_Fn with names.
-
-
- 07 May 1996
-
- Error2_VerboseExit now displays OS error using _kernel_last_oserror()
- when signal error is SIGOSERR.
-
-
- 30 Apr 1996
-
- Core.h: Added _DeskLib__Zm - defined when compilation is either for
- module (cc -Zm) or for DLL (also cc -Zm). This is because -Zm code
- doesn't like initialised static data outside of functions...
-
- Added DeskLib:o.DeskLib_M, compiled with -Zm, for use in modules.
- '_DeskLib__MODULE' is predefined for this build.
-
- Added DeskLib:o.Debug.uniquefile_m - unique-file debugging compiled with cc -Zm.
-
-
-
-
- 17 Apr 1996
-
- Added Debug_SetNestingIndentation( const char*). Subsequent ouptut from
- Debug_Printf is indented with multiple copies of the specified string,
- according to function-call nesting.
-
- Added BackTrace libray, for getting information from the stack about
- which functions are active etc.
-
-
-
- 29 Feb 1996
-
- Added Debug_Assert for Event handlers being > 0x8000
-
- 27 Feb 1996
-
- Removed close icon from TestApp's query window - caused illegal handle.
-
-
- 23 Feb 1996
-
- Fixed bug in OS_ReadVarVal_ReadIntoBuffer - sys var is now read as a
- string, and terminated according to returned length, rather than end of
- buffer.
-
-
- 22 Feb 1996
-
- Added #pragma -c0 to a Pane2.c.Open and Pane2.c.Pane2 - cc506 complains
- about internal inconsistancy.
-
-
- 12 Feb 1996
-
- Removed Debug__Dummy, and changed Debug_Dummyf macro to use printf.
- CC could generate AOF file which referenced debug_level even though it
- wasn't used in the compiled code. Fixed this by #defining
- Debug<n>_Printf straight to Debug_Dummyf.
-
-
- 09 Jan 1996
-
- Minor changes to Menu2.
-
-
- 13 Dec 1995
-
- Added jumpauto_lasterror.
-
-
- 12 Dec 1995
-
- Added Error2_GetNewErrorType
- Added File_EnsureDirectory, File_EnsureParentDirectory
- Fixed bug in Menu2 - was calling non-existent menu2 choice-handler when
- a menu2 had its own leafs.
-
-
- 01 Dec 1995
-
- Added Error2_HandleAllSignals
-
-
- 29 Nov 1995
-
- Changed Jump library.
-
-
- 19 Nov 1995
-
- Added File_AllocLoad
-
-
- 18 Nov 1995
-
- Made DeskMem use function pointer to the memory allocation functions.
- This enables a program to change what functions it uses for static
- memory at run-time. It also means that there is no need to replace
- DeskMem at link-time.
-
-
- 17 Nov 1995
-
- Moved DeskMem error-handling into a separate .c file.
-
-
- 2.35beta 16 Nov 1995
-
- Added file '...Docs.Files', which lists and has comments on (nearly) all
- the directory structure and files that make up DeskLib.
-
-
- 15 Nov 1995
-
- Added DeskLib:o.Debug.DeskLib - a version of DeskLib compiled with
- 'DeskLib_DEBUG' predefined. Only the Menu2 (and one other I think)
- library uses Debug_ calls.
-
-
-
- 14 Nov 1995
-
- Made Serial, PDriver non-DLL sublibraries.
-
- Made various libraries more SDLS compatible - many libraries called
- atexit() or Event_Claim/Release() etc without using
- _DeskLib_SDLS_dllEntry( <handlerfn>).
-
- Eg Dialog, EventMsg, Font2, Import, Menu2, Pane2, Print, Save, Template
- (font handling), Window.
-
- Fixed a bug in Menu2 - could call the wrong selection-handler if a
- non-leaf menuitem was chosen.
-
-
-
- 2.34 10 Nov 1995
-
- Added Icon_InsertText, Window_IsOpen.
-
- Added Wimp_E* macros - these are Wimp veneers which call Error2_Handle
- if the SWI returns an error.
-
- Changed DeskMem organisation a bit. To add a different static-memory
- allocator system, just provide a replacement for DeskMem.c.XCalls.
-
- Made JumpAuto_Error2Handler call Error2_Exit rather than
- Error2_VerboseExit.
-
- Added !DLMisc, for misc libraries not needed by DeskLib.
-
- Replaced SWI library with a smaller assembler version. The old one is in
- '!DLMisc'.
-
- Moved Import library into the main DeskLib distribution, from !DLUser.
-
- !DLUser is now empty..
-
-
-
-
- 07 Nov 1995
-
- Removed 'do ... while (0)' construct in the JumpAuto_TryCatch macro.
- This allows 'break' in trycode or catchcode, but means you shouldn't put
- a ';' after the macro.
-
- Made the Error2 signal-handler call signal(), to restore signal
- handling's use of Error2_SignalHandler - ANSI signal handling is reset
- to default after each signal.
-
-
- 05 Nov 1995
-
- GFX.h: Added gfx_action_ enums for graphics plot actions.
- Added ColourTrans_RGB, SetGCOL2,3.
-
-
-
- 2.33 02 Nov 1995
-
- Changed directory structure of and some filenames in 'DeskLib.Docs.'
-
- 01 Nov 1995
-
- Added '!DeskLib.sh.' directory, which contains some standard assembler
- 'header' files - 'RegDefs' and 'Macros'. Previously, every sub-library
- directory had its own copy of these two files. Changed all .s files to
- GET these new files, and deleted local versions.
-
- Changed Error2 globalblock - now has just two fields, the error type and
- a union which points to data. Errors which need some block of memory (eg
- Error2_HandleTextf) now have their own static blocks of memory - see
- DeskMem for an example.
-
-
-
- 31 Oct 1995
-
- Added ColourTrans_ReturnColourNumber and ColourTrans_ReturnGCOL.
- Added Menu_SetNotify macro.
- Changed File_SetType to be an assembler veneer, returning (os_error*).
- Added File_SetLoad, File_SetExec, File_CreateDirectory.
-
- 26 Oct 1995
-
- Changed Error2_HandleTextf to use 'bytes' field in error2_block and make
- the 'text' field point to the 'bytes' field.
-
- SmallError: Removed all refereces to event_taskname
-
-
-
- 18 Oct 1995
-
- Changed Jump DLLDef file.
-
- Changed some Pane2 external definitions to start with Pane2__ or pane2__,
- Removed Pane2's internal-only things from the DLLDef file.
-
-
- 15 Oct 1995
-
- Added #ifndef __dl_xx_h to some headers.
-
- 2.32 12 Oct 1995
-
- 11 Oct 1995
-
- Added __cplusplus to Window.h - it somehow missed out first time round...
- Added __cplusplus to Filing.h
- Added Error2_HandleText
-
-
- 05 Oct 1995
-
- Added Menu_AddSubWindow macro.
-
-
-
- 03 Oct 1995
-
- Added lots of 'const' to prototypes and altered source code accordingly.
-
-
-
- 02 Oct 1995
-
- Moved Jump library into main '!DeskLib' library.
-
- 29 Sep 1995
-
- Added JumpAuto_TryCatch macro. This enables code that looks very similar
- to C++'s try-catch constructs.
-
-
- 28 Sep 1995
-
- Added extra struct to button_type union for buttontype 10
- Added button2_* macros
-
- Added Str_StrNCpy0, and equivalent macro strncpy0
-
-
-
- 2.31
-
- This version doesn't have any SDLS or Examples.
-
-
-
-
- 23 Sep 1995
-
- New libraries in !DLUser:
-
- SWI Faster version of SWI.
- Sort Quicksort
- Hash Better hash library than previous version.
-
-
-
- 22 Sep 1995
-
- Removed blank makefile from 'DeskLib.Docs.Blanks'.
- Removed HelpCommnt directory from 'DeskLib.Docs.Blanks'.
-
-
-
- 21 Sep 1995
-
- Added ListNewer command to '!DLSources.Bin.'.
-
-
-
- 20 Sep 1995
-
- File Added File_CheckError and File_XCheckError - simple macro veneers
- for Error2_Check( file_lasterror).
-
- Added <DeskLib_Sources$Dir>.Scripts.Static.MakeLib2 and MkOList2 . These
- use Libfile -i to add any new .o files to DeskLib, rather than remaking
- the whole library.
-
- Added Every2 program to <DeskLib_Sources$Dir>.Bin .
-
- Added 'Jump' library. This (hopefully) provides SDLS-compatible
- setjmp/longjmp. Also has easy-to-use macros for automating use of
- set/longjmp, eg for use with the Error2 library.
-
-
-
- 13 Sep 1995
-
- Filing
- Allowed a 'void *reference' to be sent to Filing_ScanDir(Dir),
- and added facility to 'prune' scans through the directory tree -
- if the start-dir function returns filing_scan_PRUNE. Renamed
- the function-pointer typedefs used in Filing_ScanDir and
- Filing_ScanDirByDir.
-
- KernelSWIs
- Added OS_ReadVarVal_GetLength, OS_ReadVarVal_ReadIntoBuffer,
- OS_ReadVarVal_AutoAlloc.
-
-
-
- 12 Sep 1995
-
- objasm -throwback used in MMFs.
-
-
-
- 09 Sep 1995
-
- Added Error2 library
- Contains a simple error-handling mechanism. A few extra handlers are
- provided to help bracket (os_err *) functions, BOOL functions etc.
-
- Added Error3 library - uses Error2 and provides an Event_-style system
- for claiming errors. ***Completely untested at the moment***
-
- Added macros for every Wimp SWI veneer in WimpSWIs.h . These macros use
- Error_XHandle to provide semi-error-handling Wimp SWI calls.
-
- Made all library calls to Wimp_* use Wimp_e*, so that any error-handler
- gets to see each error.
-
- Made all libraries call DeskMem_Malloc/Calloc/Realloc/Free instead of
- the <stdlib.h> functions.
-
- Added DeskMem library whihc impla\ements the DeskMem functions (to use
- malloc et al). The plan is to have alternative DeskMem libs (eg which se
- Mem_ calls).
-
-
-
- 2.30 (02 Sep 1995)
-
-
