So using them in delphi is a ticking time-bomb because sooner or + * later they will crash because of an FPE (this problem occurs massively + * in OpenGL-based libs like projectM). In contrast to this no error will occur + * if the lib is linked to a C-program. + * + * Further info on FPUs: + * For x86 and x86_64 CPUs we have to consider two FPU instruction sets. + * The math co-processor i387 (aka 8087 or x87) set introduced with the i386 + * and SSE (Streaming SIMD Extensions) introduced with the Pentium3. + * Both of them have separate control-registers (x87: FPUControlWord, SSE: MXCSR) + * to control FPEs. Either has (among others) 6bits to enable/disable several + * exception types (Invalid,Denormalized,Zero,Overflow,Underflow,Precision). + * Those exception-types must all be masked (=1) to get the default C behaviour. + * The control-registers can be set with the asm-ops FLDCW (x87) and LDMXCSR (SSE). + * Instead of using assembler code, we can use Set8087CW() provided by delphi and + * FPC to set the x87 control-word. FPC also provides SetSSECSR() for SSE's MXCSR. + * Note that both Delphi and FPC enable FPEs (e.g. for div-by-zero) on program + * startup but only FPC enables FPEs (especially div-by-zero) for SSE too. + * So we have to mask FPEs for x87 in Delphi and FPC and for SSE in FPC only. + * FPC and Delphi both provide a SetExceptionMask() for control of the FPE + * mask. SetExceptionMask() sets the masks for x87 in Delphi and for x87 and SSE + * in FPC (seems as if Delphi [2005] is not SSE aware). So SetExceptionMask() + * is what we need and it even is plattform and CPU independent. + * + * Pascal OpenGL headers (like the Delphi standard ones or JEDI-SDL headers) + * already call Set8087CW() to disable FPEs but due to some bugs in the JEDI-SDL + * headers they do not work properly with FPC. I already patched them, so they + * work at least until they are updated the next time. In addition Set8086CW() + * does not suffice to disable FPEs because the SSE FPEs are not disabled by this. + * FPEs with SSE are a big problem with some libs because many linux distributions + * optimize code for SSE or Pentium3 (for example: int(INF) which convert the + * double value "infinity" to an integer might be automatically optimized by + * using SSE's CVTSD2SI instruction).

+=============================================================================================== +Project : All Projects +=============================================================================================== +Subject : Progressive XML Parser for all types of XML Files +=============================================================================================== +Author : Stefan Heymann + Eschenweg 3 + 72076 Tübingen + GERMANY + +E-Mail: stefan@destructor.de +URL: www.destructor.de +=============================================================================================== +Source, Legals ("Licence") +-------------------------- +The official site to get this parser is http://www.destructor.de/ + +Usage and Distribution of this Source Code is ruled by the +"Destructor.de Source code Licence" (DSL) which comes with this file or +can be downloaded at http://www.destructor.de/ + +IN SHORT: Usage and distribution of this source code is free. + You use it completely on your own risk. + +Postcardware +------------ +If you like this code, please send a postcard of your city to my above address. +=============================================================================================== +!!! 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.

For instance, Delphi 5's design package is TntUnicodeVcl_D50.dpk. + +For BCB 2006 and newer, open the appropriate design package in the packages\bcbx\ folder using the Delphi personality. After compiling and installing, you should be able to use the components in both the Delphi and BCB personality. Remember to set the library path in menu "Tools->Options" for both the C++ Builder and the Delphi. + + +---A note on fonts---------------------- + +The default TFont uses "MS Sans Serif" which doesn't work well with most non-ANSI characters. I'd recommend using a TrueType font such as "Tahoma" if it is installed on the machine. To make TFont use a different font like "Tahoma" add this to the first line in the project: + + Graphics.DefFontData.Name := 'Tahoma'; + +You might have to include "Graphics" in the file's uses clauses. Furthermore, adding this line of code to the project will cause the changed setting to only be applied at runtime, not at design time. To make a designtime change, you'd have to add this line to the initialization section of a unit in a design package. + +Regarding the IDE, I use GExperts to change the font of the Object Inspector. The Wide String List editor uses the font used by the object inspector. + +Also keep in mind that the font used by certain message boxes come from that set by Windows' Display properties. + + +---Background---------------------------- + +Designing software for an international audience, I've always wanted to write a full UNICODE application. My approach so far, has been to write Unicode on the inside, and MBCS on the outside. This has always been frustrating, because (even on Windows NT/2000/XP which provide native Unicode window controls) the WideStrings inside my application and databases were always confined to an ANSI VCL. And, since the VCL was designed to wrap the low-level Windows details, why shouldn't the VCL hide the fact that sometimes native Unicode controls are not possible on the given version of Windows. I believe the VCL should be written with a Unicode interface, even if it must (at times) deal with an ANSI operating system. For example, TEdit should expose Text as a WideString, even if it has to convert the WideString to an AnsiString on the Windows 9X platform. + +In the past, the ANSI VCL may have made a little sense, considering that there were many more users of Windows 9X, than Windows NT. There would have been some performance penalty to use WideStrings on the Windows 9X platform. But with the faster computers of today, and with more people using platforms such as Windows 2000 and Windows XP, the ANSI VCL just doesn't make sense anymore. In fact, having to use the the ANSI VCL on Windows NT/2000/XP is slower because of the constant conversion to and from UNICODE inside Windows. + +My coding signature is Tnt. I will use this to denote my classes from others. + +For more information about me: +Some of my software projects (all written in Delphi). + TntMPD (contact manager for missionaries) + + Jesus Film Screen Saver + + ActiveX SCR control + + +---Design Goals---------------------------- + +I want the controls to work on Windows 95, 98, ME, NT, 2000, XP, etc. I want a single EXE for all platforms. Of course, full UNICODE support is only truly available on NT/2000/XP. In other words, the controls should automatically scale to take advantage of native Unicode support when possible. + +I want the controls to inherit from the Delphi VCL. I want to reuse as much code as possible. For the most part this makes sense. The only sticky part is where text messages get passed around. But I believe I've gotten past this through strategic subclassing at various points in the message flow chain. To give a rough comparison of why this is so important, check out the following chart which compares the lines of code in the VCL for a given control (4,397 in all), and the lines of code required in my descendent controls (655 in all). Besides saving lines of code, I get the advantage of automatically inheriting new features as new versions of Delphi come out. One such example is the AlphaBlending feature in the Delphi 6 TForm. Even though I use Delphi 5 now, I won't have to add any code to get this new feature. + +---More Interesting Information---------------------------- +Case Study: Porting an MFC Application to Unicode: It looks like the FrontPage 2002 team did the roughly the same thing to MFC as what I'm doing to the VCL. They did this with the same goal in mind: to support Unicode as much as possible depending on the support offered by Windows. Another goal was "Don’t abandon MFC; don’t rewrite app". Because they still want to support Windows 9X using the same worldwide EXE used everywhere. They couldn't just compile with the _UNICODE directive. They had to start with the ANSI MFC, strategically subclassing window procedures at just the right places.

library for use in Windows and MacOSX software. 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, with both "push" and "pull" systems + +* File streams + MP3/MP2/MP1/OGG/WAV/AIFF file streaming + +* Internet file streaming + stream files from the internet, including Shout/Icecast + +* User file streaming + stream 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 MOD musics can be outputted in any way you want + +* Speaker assignment + assign streams and MOD musics to specific speakers + +* High precision synchronization + synchronize events in your software to the streams and MOD musics + +* 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 + +* 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. + +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 + +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 + + +Licence +======= +BASS is free for non-commercial use. If you are a non-commercial entity +(eg. an individual) and you 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. 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. + +Commercial licensing +-------------------- +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 are an individual (not a corporation) 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 does not 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!

The outline data can be accessed from the + * glyph slot (see note below). + * + * Note that by default, the glyph loader doesn't render outlines into + * bitmaps. The following flags are used to modify this default + * behaviour to more specific and useful cases. + * + * FT_LOAD_NO_SCALE :: + * Don't scale the vector outline being loaded to 26.6 fractional + * pixels, but kept in font units. Note that this also disables + * hinting and the loading of embedded bitmaps. You should only use it + * when you want to retrieve the original glyph outlines in font units. + * + * FT_LOAD_NO_HINTING :: + * Don't hint glyph outlines after their scaling to device pixels. + * This generally generates "blurrier" glyphs in anti-aliased modes. + * + * This flag is ignored if @FT_LOAD_NO_SCALE is set. + * + * FT_LOAD_RENDER :: + * Render the glyph outline immediately into a bitmap before the glyph + * loader returns. By default, the glyph is rendered for the + * @FT_RENDER_MODE_NORMAL mode, which corresponds to 8-bit anti-aliased + * bitmaps using 256 opacity levels. You can use either + * @FT_LOAD_TARGET_MONO or @FT_LOAD_MONOCHROME to render 1-bit + * monochrome bitmaps. + * + * This flag is ignored if @FT_LOAD_NO_SCALE is set. + * + * FT_LOAD_NO_BITMAP :: + * Don't look for bitmaps when loading the glyph. Only scalable + * outlines will be loaded when available, and scaled, hinted, or + * rendered depending on other bit flags. + * + * This does not prevent you from rendering outlines to bitmaps + * with @FT_LOAD_RENDER, however. + * + * FT_LOAD_VERTICAL_LAYOUT :: + * Prepare the glyph image for vertical text layout. This basically + * means that `face.glyph.advance' will correspond to the vertical + * advance height (instead of the default horizontal advance width), + * and that the glyph image will be translated to match the vertical + * bearings positions. + * + * FT_LOAD_FORCE_AUTOHINT :: + * Force the use of the FreeType auto-hinter when a glyph outline is + * loaded. You shouldn't need this in a typical application, since it + * is mostly used to experiment with its algorithm. + * + * FT_LOAD_CROP_BITMAP :: + * Indicates that the glyph loader should try to crop the bitmap (i.e., + * remove all space around its black bits) when loading it. This is + * only useful when loading embedded bitmaps in certain fonts, since + * bitmaps rendered with @FT_LOAD_RENDER are always cropped by default. + * + * FT_LOAD_PEDANTIC :: + * Indicates that the glyph loader should perform pedantic + * verifications during glyph loading, rejecting invalid fonts. This + * is mostly used to detect broken glyphs in fonts. By default, + * FreeType tries to handle broken fonts also. + * + * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: + * Indicates that the glyph loader should ignore the global advance + * width defined in the font.

It merely indicates that the + * glyph loader should not load composite glyphs recursively. Instead, + * it should set the `num_subglyph' and `subglyphs' values of the glyph + * slot accordingly, and set "glyph->format" to + * @FT_GLYPH_FORMAT_COMPOSITE. + * + * The description of sub-glyphs is not available to client + * applications for now. + * + * FT_LOAD_IGNORE_TRANSFORM :: + * Indicates that the glyph loader should not try to transform the + * loaded glyph image. This doesn't prevent scaling, hinting, or + * rendering. + * + * FT_LOAD_MONOCHROME :: + * This flag is used with @FT_LOAD_RENDER to indicate that you want + * to render a 1-bit monochrome glyph bitmap from a vectorial outline. + * + * Note that this has no effect on the hinting algorithm used by the + * glyph loader.
