From 30343a531999b5e50673ee1731f1c54cbc008dfd Mon Sep 17 00:00:00 2001 From: jaybinks Date: Wed, 5 Sep 2007 12:02:06 +0000 Subject: added 3rd party dependencies ( except Jedi-SDL ) modified DPR to statically include all files needed (using relative paths) this means 3rd party components should not need installation in the IDE, or adding to search paths. git-svn-id:

Its +purpose is to provide the most powerful and efficient (yet easy to use), +sample, stream, MOD music, and recording functions. All in a tiny DLL, +under 100KB in size. + +See the documentation for descriptions of all the BASS functions. You +should also look at the included example program source-codes for some +examples of how to use BASS in your own programs. + + +Requirements +============ +Win32 version +------------- +BASS requires DirectX 3 or above for output. BASS does not require that a +soundcard with DirectSound/DirectSound3D hardware accelerated drivers is +installed, but it does improve performance if there is one. BASS also takes +advantage of MMX, which improves the performance of the MOD music playback. + +MacOSX version +-------------- +OSX 10.3 or above is recommended. BASS uses CoreAudio for output, so there +are no special library/driver requirements. BASS supports both PowerPC and +Intel Macs. + + +Main Features +============= +* Samples +- supports WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples + +* Sample streams +- stream any sample data in 8/16/32 bit + +* File streams +- MP3/MP2/MP1/OGG/WAV/AIFF file streaming + +* Internet file streaming +- stream MP3/MP2/MP1/OGG/WAV/AIFF files from the internet (inc. Shout/Icecast) + +* User file streaming +- stream MP3/MP2/MP1/OGG/WAV/AIFF files from anywhere using any delivery method + +* Multi-channel streaming +- support for more than plain stereo, including multi-channel OGG/WAV/AIFF files + +* MOD music +- uses the same engine as XMPlay = best accuracy, speed and quality + +* MO3 music +- MP3/OGG compressed MOD music + +* Add-on system +- support for more formats is available via add-ons (aka plugins) + +* Multiple outputs +- simultaneously use multiple soundcards, and move channels between them + +* Recording +- flexible recording system, with support for multiple devices + +* Decode without playback +- streams and musics can be outputted in any way you want + +* Speaker assignment +- assign streams and musics to specific speakers + +* High precision synchronization +- synchronize events in your software to the music + +* DirectX 8 effects +- chorus/compressor/distortion/echo/flanger/gargle/parameq/reverb + +* User defined DSP functions +- custom effects may be applied to musics and streams + +* 32 bit floating-point decoding and processing +- floating-point stream/music decoding, DSP, FX, and recording + +* 3D sound +- play samples/streams/musics in any 3D position, with EAX support + +* Expandable +- underlying DirectSound object interfaces are accessible + +* Small +- BASS is under 100KB (on Windows), so won't bloat your distribution + + +Using BASS +========== +There is no guarantee that all future BASS versions will be compatible +with all previous versions, so your program should use BASS_GetVersion +to check the version that is loaded. This also means that you should +put the BASS module in the same directory as your executable (not just +somewhere in the path), to avoid the possibility of a wrong version being +loaded. + +If you are updating your software from a previous BASS version, then +you should check the "History" section (below), to see if any of the +functions that you are using have been affected by a change. + +Win32 version +------------- +C/C++, Visual Basic, Delphi and MASM APIs are provided, to use BASS with +another language you'll first have to convert the header file. Or, as a +last resort, you could use LoadLibrary and GetProcAddress. + +One benefit of the LoadLibrary method is that it allows you to look for +the correct BASS version, because you can load and unload BASS.DLL at +any time. This also allows those who'd prefer not to have a separate +DLL to store it with the program (eg. in a resource), write it to disk, +load it, use it, free it and delete it. + +The downside is that you have to manually import each function that you +use, with the GetProcAddress function. But it has been made a lot simpler +to import BASS this way by the use of the BASSDEF #define. Here's a small +example: + +#define BASSDEF(f) (WINAPI *f) // define the functions as pointers +#include "bass.h" +... +HINSTANCE bass=LoadLibrary("BASS.DLL"); // load BASS +BASS_Init=GetProcAddress(bass,"BASS_Init"); // get BASS_Init +BASS_Init(-1,44100,0,hWnd,NULL); // call BASS_Init + +See the LOADNGET.C file for a more complete example. + +To use BASS with Borland C++ Builder, you'll first have to create a +Borland C++ Builder import library for it. This is done by using the +IMPLIB tool that comes with Borland C++ Builder. Simply execute this: + + IMPLIB BASSBCB.LIB BASS.DLL + +... and then use BASSBCB.LIB in your projects to import BASS. + +To use BASS with LCC-Win32, you'll first have to create a compatible +import library for it. This is done by using the PEDUMP and BUILDLIB +tools that come with LCC-Win32. Run these 2 commands: + + PEDUMP /EXP BASS.LIB > BASSLCC.EXP + BUILDLIB BASSLCC.EXP BASSLCC.LIB + +... and then use BASSLCC.LIB in your projects to import BASS. + +For the BASS functions that return strings (char*), VB users should use +the VBStrFromAnsiPtr function to convert the returned pointer into a VB +string. + +MacOSX version +-------------- +A separate "LIB" file is not required for OSX. Using XCode, you can simply +add the DYLIB file to the project. Or using a makefile, you can build your +programs like this, for example: + + gcc yoursource -L. -lbass -o yourprog + +The LIBBASS.DYLIB file must be put in the same directory as the executable +(it can't just be somewhere in the path). See the example makefiles. + +LIBBASS.DYLIB is a universal binary, with support for both PowerPC and +Intel Macs. If you want PowerPC-only or Intel-only versions, the included +makefile can create them for you, by typing "make ppc" or "make i386". It +will also process any BASS add-ons placed in the same directory. + + +Latest Version +============== +The latest version of BASS can always be found at the BASS website: + + www.un4seen.com + + +Copyright, disclaimer, and all that other jazz +============================================== +The BASS library is free for non-commercial use. If you are a non- +commercial entity (eg. an individual) and are not charging for your +product, and the product has no other commercial purpose, then you +can use BASS in it for free. If you wish to use BASS in commercial +products, then please also see the next section. + +TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BASS IS PROVIDED +"AS IS", WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, +INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY +AND/OR FITNESS FOR A PARTICULAR PURPOSE. THE AUTHORS SHALL NOT BE HELD +LIABLE FOR ANY DAMAGE THAT MAY RESULT FROM THE USE OF BASS. BASICALLY, +YOU USE BASS ENTIRELY AT YOUR OWN RISK. + +Usage of BASS indicates that you agree to the above conditions. + +All trademarks and other registered names contained in the BASS +package are the property of their respective owners. + + +BASS in commercial products? +============================ +BASS is available for use in your commercial products. The licence +types available are as follows: + +SHAREWARE: Allows the usage of BASS in an unlimited number of your +shareware products, which must sell for no more than 40 Euros each. +If you're an individual making and selling your own software (and +its price is within the limit), this is the licence for you. + +SINGLE COMMERCIAL: Allows the usage of BASS in a single commercial +product. + +UNLIMITED COMMERCIAL: Allows the usage of BASS in an unlimited number +of your commercial products. This licence is on a per site basis. So +if your company has two sites that use BASS, then two licences are +required. + +Please note the products must be end-user products, eg. not components +used by other products. + +These licences only cover your own software. not the publishing of +other's software. If you publish other's software, its developers (or +the software itself) will need to be licensed to use BASS. + +These licences are on a per-platform basis, with reductions available +when licensing for both platforms. In all cases there are no royalties +to pay, and you can use future BASS updates without further cost. One +licence covers one person or entity and is not transferable. + +These licences do not allow reselling/sublicensing of BASS. For example, +if a product is a development system, the users of said product are not +licensed to use BASS in their productions - they will need their own +licences. + +If the standard licences do not meet your requirements, or if you have +any questions, please get in touch (email: bass@un4seen.com). + +Visit the BASS website for the latest pricing: + + www.un4seen.com + + +MP3 +=== +MP3 technology is patented, and Thomson license the use of their and +Fraunhofer's patents. The inclusion of an MP3 decoder (eg. BASS) in a +commercial product requires an MP3 patent licence. Contact Thomson for +details: + + www.mp3licensing.com + +Alternatively, the "MP3-FREE" BASS version doesn't include its own MP3 +decoder but instead makes use of the operating system's already licensed +decoder. + +NOTE: When using the OS's MP3 decoder, BASS still does the file handling + so all the usual features are still supported, including streaming, + tag reading, pre-scanning, gapless playback, etc... + + +History +======= +These are the major (and not so major) changes at each version stage. +There are of course bug fixes and other little improvements made along +the way too!

Two of them (GLDiag and GLTest) +need the (also provided) simple OpenGL control GLControl (see "GLControl\Package"). + +- Basic is a very simple test program which only uses an empty form. +- GLTest (in GLControl) uses GLControl to show four rendering contexts simultanously. +- GLDiag is a diagnosis tool similar to DXDiag which shows some properties of the current + OpenGL driver implementation. + +Have fun and + +Ciao, Mike +www.lischke-online.de +www.delphi-unicode.net \ No newline at end of file diff --git a/Game/Code/lib/JEDI-SDLv1.0/SDL/Pas/jedi-sdl.inc b/Game/Code/lib/JEDI-SDLv1.0/SDL/Pas/jedi-sdl.inc new file mode 100644 index 00000000..48a789fd --- /dev/null +++ b/Game/Code/lib/JEDI-SDLv1.0/SDL/Pas/jedi-sdl.inc @@ -0,0 +1,337 @@ +{ + $Id: jedi-sdl.inc,v 1.9 2004/12/23 23:42:17 savage Exp $ +} +{******************************************************************************} +{ } +{ Borland Delphi SDL - Simple DirectMedia Layer } +{ Global Conditional Definitions for JEDI-SDL cross-compilation } +{ } +{ } +{ The initial developer of this Pascal code was : } +{ Prof. Abimbola Olowofoyeku } +{ } +{ Portions created by Prof. Abimbola Olowofoyeku are } +{ Copyright (C) 2000 - 2100 Prof. Abimbola Olowofoyeku. } +{ } +{ } +{ Contributor(s) } +{ -------------- } +{ Prof. Abimbola Olowofoyeku } +{ Dominqiue Louis } +{ } +{ Obtained through: } +{ Joint Endeavour of Delphi Innovators ( Project JEDI ) } +{ } +{ You may retrieve the latest version of this file at the Project } +{ JEDI home page, located at http://delphi-jedi.org } +{ } +{ The contents of this file are used with permission, subject to } +{ the Mozilla Public License Version 1.1 (the "License"); you may } +{ not use this file except in compliance with the License.

If you want your +application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever +protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. +"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated +string, thereby creating a copy of that buffer. +"SetBuffer" just takes the pointer to another buffer, which means that the given +buffer pointer must be valid while the document is accessed via TXmlParser. +=============================================================================================== +Encodings: +---------- +This XML parser kind of "understands" the following encodings: +- UTF-8 +- ISO-8859-1 +- Windows-1252 + +Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. + +Every string which has to be passed to the application passes the virtual method +"TranslateEncoding" which translates the string from the current encoding (stored in +"CurEncoding") into the encoding the application wishes to receive. +The "TranslateEncoding" method that is built into TXmlParser assumes that the application +wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able +to convert UTF-8 and ISO-8859-1 encodings. +For other source and target encodings, you will have to override "TranslateEncoding". +=============================================================================================== +Buffer Handling +--------------- +- The document must be loaded completely into a piece of RAM +- All character positions are referenced by PChar pointers +- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) + or reference the buffer of another instance or object (then, FBuffersize is 0 and + FBuffer is not NIL) +- The Property DocBuffer passes back a pointer to the first byte of the document. If there + is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. +=============================================================================================== +Whitespace Handling +------------------- +The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: +While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all +Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are +compressed to one. +If the "Scan" method reports a ptContent part, the application can get the original text +with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". +If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or +use CurStart/CurFinal. +Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters +as the XmlSpec requires (XmlSpec 2.11). +The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. +=============================================================================================== +Non-XML-Conforming +------------------ +TXmlParser does not conform 100 % exactly to the XmlSpec: +- UTF-16 is not supported (XmlSpec 2.2) + (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) +- As the parser only works with single byte strings, all Unicode characters > 255 + can currently not be handled correctly. +- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) + (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], + thereby applying every normalization it wishes to) +- The attribute value normalization does not work exactly as defined in the + Second Edition of the XML 1.0 specification. +- See also the code parts marked with three consecutive exclamation marks.

A Plasma example which was converted from one found on the Demos page of the SDL site. + +3. A Voxel terrain following demo, which was converted from one found on the Demos page of the SDL site. This one should be of interest to others as it shows how to handle keyboard events when using SDL. + +4. A Mouse handling demo that shows how to use transparency and clickable regions. + +5. A Space Invaders style game called Aliens which shows the use of SDL, SDL_Image and SDL_Mixer. This game shows how to handle sound, keyboards and some basic collision detection. It is a conversion of one found on the SDL Demos page. + +There are also 14 OpenGL demos that are based on the NeHe tutorials . The other 3 OpenGL demos are Jan Horns' OpenGL demo, A Quake 2 Model viewer that I ported and a Demo by Gustavo Maxima called Puntos. + +If writing your own, just make sure that the SDL.pas file is in your projects path for compiling and that the SDL.dll file is in your path when running the compiled app. + +Please test these units and report problems to the JEDI-SDL mailing list @ http://groups.yahoo.com/group/JEDI-SDL/ outlining steps under which the error occurred.

It is specifically designed +// for geometric calculations within R3 (affine vector space) +// and R4 (homogeneous vector space). +// +// Note: The terms 'affine' or 'affine coordinates' are not really correct here +// because an 'affine transformation' describes generally a transformation which leads +// to a uniquely solvable system of equations and has nothing to do with the dimensionality +// of a vector. One could use 'projective coordinates' but this is also not really correct +// and since I haven't found a better name (or even any correct one), 'affine' is as good +// as any other one. +// +// Identifiers containing no dimensionality (like affine or homogeneous) +// and no datatype (integer..extended) are supposed as R4 representation +// with 'single' floating point type (examples are TVector, TMatrix, +// and TQuaternion). The default data type is 'single' ('GLFloat' for OpenGL) +// and used in all routines (except conversions and trigonometric functions). +// +// Routines with an open array as argument can either take Func([1,2,3,4,..]) or Func(Vect). +// The latter is prefered, since no extra stack operations is required. +// Note: Be careful while passing open array elements! If you pass more elements +// than there's room in the result the behaviour will be unpredictable. +// +// If not otherwise stated, all angles are given in radians +// (instead of degrees). Use RadToDeg or DegToRad to convert between them. +// +// Geometry.pas was assembled from different sources (like GraphicGems) +// and relevant books or based on self written code, respectivly. +// +// Note: Some aspects need to be considered when using Delphi and pure +// assembler code. Delphi ensures that the direction flag is always +// cleared while entering a function and expects it cleared on return. +// This is in particular important in routines with (CPU) string commands (MOVSD etc.) +// The registers EDI, ESI and EBX (as well as the stack management +// registers EBP and ESP) must not be changed!

All parts of this code which are not finished or not conforming exactly to + the XmlSpec are marked with three exclamation marks + +-!- Parts where the parser may be able to detect errors in the document's syntax are + marked with the dash-exlamation mark-dash sequence. +=============================================================================================== +Terminology: +------------ +- Start: Start of a buffer part +- Final: End (last character) of a buffer part +- DTD: Document Type Definition +- DTDc: Document Type Declaration +- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. +- Cur*: Fields concerning the "Current" part passed back by the "Scan" method +=============================================================================================== +Scanning the XML document +------------------------- +- Create TXmlParser Instance MyXml := TXmlParser.Create; +- Load XML Document MyXml.LoadFromFile (Filename); +- Start Scanning MyXml.StartScan; +- Scan Loop WHILE MyXml.Scan DO +- Test for Part Type CASE MyXml.CurPartType OF +- Handle Parts ... : ;;; +- Handle Parts ... : ;;; +- Handle Parts ... : ;;; + END; +- Destroy MyXml.Free; +=============================================================================================== +Loading the XML document +------------------------ +You can load the XML document from a file with the "LoadFromFile" method. +It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your +application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever +protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. +"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated +string, thereby creating a copy of that buffer. +"SetBuffer" just takes the pointer to another buffer, which means that the given +buffer pointer must be valid while the document is accessed via TXmlParser. +=============================================================================================== +Encodings: +---------- +This XML parser kind of "understands" the following encodings: +- UTF-8 +- ISO-8859-1 +- Windows-1252 + +Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. + +Every string which has to be passed to the application passes the virtual method +"TranslateEncoding" which translates the string from the current encoding (stored in +"CurEncoding") into the encoding the application wishes to receive. +The "TranslateEncoding" method that is built into TXmlParser assumes that the application +wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able +to convert UTF-8 and ISO-8859-1 encodings. +For other source and target encodings, you will have to override "TranslateEncoding". +=============================================================================================== +Buffer Handling +--------------- +- The document must be loaded completely into a piece of RAM +- All character positions are referenced by PChar pointers +- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) + or reference the buffer of another instance or object (then, FBuffersize is 0 and + FBuffer is not NIL) +- The Property DocBuffer passes back a pointer to the first byte of the document. If there + is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. +=============================================================================================== +Whitespace Handling +------------------- +The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: +While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all +Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are +compressed to one. +If the "Scan" method reports a ptContent part, the application can get the original text +with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". +If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or +use CurStart/CurFinal. +Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters +as the XmlSpec requires (XmlSpec 2.11). +The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. +=============================================================================================== +Non-XML-Conforming +------------------ +TXmlParser does not conform 100 % exactly to the XmlSpec: +- UTF-16 is not supported (XmlSpec 2.2) + (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) +- As the parser only works with single byte strings, all Unicode characters > 255 + can currently not be handled correctly. +- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) + (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], + thereby applying every normalization it wishes to) +- The attribute value normalization does not work exactly as defined in the + Second Edition of the XML 1.0 specification. +- See also the code parts marked with three consecutive exclamation marks. These are + parts which are not finished in the current code release. + +This list may be incomplete, so it may grow if I get to know any other points. +As work on the parser proceeds, this list may also shrink. +=============================================================================================== +Things Todo +----------- +- Introduce a new event/callback which is called when there is an unresolvable + entity or character reference +- Support Unicode +- Use Streams instead of reading the whole XML into memory +=============================================================================================== +Change History, Version numbers +------------------------------- +The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. +Versions are counted from 1.0.0 beginning with the version from 2000-03-16. +Unreleased versions don't get a version number. + +Date Author Version Changes +----------------------------------------------------------------------------------------------- +2000-03-16 HeySt 1.0.0 Start +2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site +2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent +2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) +2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; + Should be backwards compatible. + AnalyzeDtdc: Set CurPartType to ptDtdc +2000-04-23 HeySt 1.0.5 New class TObjectList.

All parts of this code which are not finished or not conforming exactly to - the XmlSpec are marked with three exclamation marks - --!- Parts where the parser may be able to detect errors in the document's syntax are - marked with the dash-exlamation mark-dash sequence. -=============================================================================================== -Terminology: ------------- -- Start: Start of a buffer part -- Final: End (last character) of a buffer part -- DTD: Document Type Definition -- DTDc: Document Type Declaration -- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. -- Cur*: Fields concerning the "Current" part passed back by the "Scan" method -=============================================================================================== -Scanning the XML document -------------------------- -- Create TXmlParser Instance MyXml := TXmlParser.Create; -- Load XML Document MyXml.LoadFromFile (Filename); -- Start Scanning MyXml.StartScan; -- Scan Loop WHILE MyXml.Scan DO -- Test for Part Type CASE MyXml.CurPartType OF -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; - END; -- Destroy MyXml.Free; -=============================================================================================== -Loading the XML document ------------------------- -You can load the XML document from a file with the "LoadFromFile" method. -It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your -application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever -protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. -"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated -string, thereby creating a copy of that buffer. -"SetBuffer" just takes the pointer to another buffer, which means that the given -buffer pointer must be valid while the document is accessed via TXmlParser. -=============================================================================================== -Encodings: ----------- -This XML parser kind of "understands" the following encodings: -- UTF-8 -- ISO-8859-1 -- Windows-1252 - -Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. - -Every string which has to be passed to the application passes the virtual method -"TranslateEncoding" which translates the string from the current encoding (stored in -"CurEncoding") into the encoding the application wishes to receive. -The "TranslateEncoding" method that is built into TXmlParser assumes that the application -wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able -to convert UTF-8 and ISO-8859-1 encodings. -For other source and target encodings, you will have to override "TranslateEncoding". -=============================================================================================== -Buffer Handling ---------------- -- The document must be loaded completely into a piece of RAM -- All character positions are referenced by PChar pointers -- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) - or reference the buffer of another instance or object (then, FBuffersize is 0 and - FBuffer is not NIL) -- The Property DocBuffer passes back a pointer to the first byte of the document. If there - is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. -=============================================================================================== -Whitespace Handling -------------------- -The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: -While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all -Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are -compressed to one. -If the "Scan" method reports a ptContent part, the application can get the original text -with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". -If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or -use CurStart/CurFinal. -Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters -as the XmlSpec requires (XmlSpec 2.11). -The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. -=============================================================================================== -Non-XML-Conforming ------------------- -TXmlParser does not conform 100 % exactly to the XmlSpec: -- UTF-16 is not supported (XmlSpec 2.2) - (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) -- As the parser only works with single byte strings, all Unicode characters > 255 - can currently not be handled correctly. -- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) - (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], - thereby applying every normalization it wishes to) -- The attribute value normalization does not work exactly as defined in the - Second Edition of the XML 1.0 specification. -- See also the code parts marked with three consecutive exclamation marks. These are - parts which are not finished in the current code release. - -This list may be incomplete, so it may grow if I get to know any other points. -As work on the parser proceeds, this list may also shrink. -=============================================================================================== -Things Todo ------------ -- Introduce a new event/callback which is called when there is an unresolvable - entity or character reference -- Support Unicode -- Use Streams instead of reading the whole XML into memory -=============================================================================================== -Change History, Version numbers -------------------------------- -The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. -Versions are counted from 1.0.0 beginning with the version from 2000-03-16. -Unreleased versions don't get a version number. - -Date Author Version Changes ------------------------------------------------------------------------------------------------ -2000-03-16 HeySt 1.0.0 Start -2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site -2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent -2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) -2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; - Should be backwards compatible. - AnalyzeDtdc: Set CurPartType to ptDtdc -2000-04-23 HeySt 1.0.5 New class TObjectList.
