旼컴컴컴컴컴컴컴컴컴컴컴컴캠 � What is SAUCE? � 익袴袴袴袴袴袴袴袴袴袴袴袴暠 Recipe for SAUCE Chef cuisinier : Tasmaniac / ACiD Maitre d'h뱓el : RaD Man / ACiD ANSi's used to be just ANSi's, pictures were just pictures, loaders were just loaders and quite frankly, every file was just as plain tasting as every other. This is about to change, how- ever, because ACiD has decided to give their files an extra "je-ne-sais-quoi." In reality, we'll be adding SAUCE to every file you can imagine. Now, before we thoroughly confuse you, let us explain what we are doing here. SAUCE stands for "Standard Architecture for Universal Comment Extensions." Although originally intended for personal use in ANSi's and RIP screens, early in the developement of EFI (Extended File Information) it was decided that EFI should be extended to have support for more than just ANSi and RIP screens. Our brainchild was born and the specs were designed. The only aspect left undecided was the name, and after rejecting some very funny candidates, SAUCE was unanimously chosen. This leads us to the big question in the sky, "What is SAUCE ?" SAUCE is a universal process to incorporate a full description for any type of file. The most outstanding aspect of this concept is that you have access to the complete file name, the file's title, the creation date, the creator of the file, the group that the creator is employed by, and much, much, more. A full explanation on how you can implement SAUCE is described at the end of this document in the PLATES (Programming Language Architecture To Extract SAUCE) section. Although you can create your own programs to implement SAUCE to your files, we recommend that you use the SPOON.EXE program to ensure a greater universal compatibility. SAUCE already supports a plethora of filetypes (See PLATES). If you have a need for the SAUCE specifications, please contact us before you make the changes yourself. We will accomodate your needs as soon as possible. After all, SAUCE is designed to become a standard, and if people change the specs without allowing us to make a complete update, there will be no standard. In the event that we change SAUCE, we will quickly release a public update which will most definately include an improved and updated SPOON.EXE. SAUCE has advantages over any other system in use. Each description will be added to the file and will provide a file description no matter what computer it is used for. SAUCE, how- ever, also provides a back compatibility that uses a file with descriptions for those files that do NOT already have a SAUCE description. Processing in this manner is fully implemented in SPOON.EXE and one can extract embedded SAUCE to this data file and add SAUCE to files from this data file. 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커 � � � ! NOTICE ! � � � � SAUCE was initially created for supporting only the ANSi & RIP � � screens. Since both ANSi and RIP are in effect text-based and � � have no other form of control, SAUCE never interferes with the � � workings of a program using either ANSi or RIP. If it does, � � the program is not functioning the way it should. � � This is _NOT_ true for the other types of file SAUCE supports � � however. Adding SAUCE to some of the other filetypes supported � � in the SAUCE specifications may have serious consequences on � � the proper functioning of other programs using those files, � � In the worst case, they'll simply refuse the file, stating it � � is invalid. � � � � It's not up to us to decide whether or not adding SAUCE is a � � bad thing. The one who added the SAUCE to the file should be � � fully aware of any problems that can arise when 'SAUCEing' a � � file other than the 'Character' or XBIN datatypes. � � � � You may have your own specialized viewing/editing tools and � � simply not care about the file not being recognized in other � � viewing/editing programs. � � � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴켸 PLATES ------ Let us begin with a description of the record layouts used. The record layouts and code examples are in a variated pascal pseudo code, and should be transferrable enough to implement in most other programming languages. For ease of reading, the examples assume that the file is correct and that no error- checking need be included. How rigorous you check for errors is completely up to you, and will most likely depend on the file type you are describing. SAUCE RECORD ------------ This portion of the documentation is about the SAUCE record. The SAUCE record describes the file in short, and provides other information not included in the SAUCE record itself. A sauce record is _EXACTLY_ 128 bytes in size. Fieldname : Name of the field. Size : Size of the field in BYTES Type : Type of data. This can be : BYTE : One byte unsigned numeric value (0 to 255) WORD : Two byte unsigned numeric value (0 to 65535) INTEGER : Two byte signed numeric value (-32768 to 32767) LONG : Four byte signed numeric value (-2147483648 to 2147483647) CHARACTER : One byte ASCII value. Longer character fields are padded with spaces. It is _NOT_ a PASCAL string (with a leading length byte), and it's _NOT_ a C-Style string (with a trailing nul-byte). A 10 byte character field holding the text 'ANSI' would look like this: 'ANSI '. Numeric fields should be zero when not used, character fields should be all spaces when not used. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! No fields are REQUIRED to be filled in except for ID, Version, FileSize, DataType and FileType. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! V# : SAUCE Version number. This indicates the version of SAUCE when the field was implemented. Description : Complete description of the field. FieldName Size Type V# Description --------- ---- --------- -- ----------- ID 5 Character 00 SAUCE Identification. This should be equal to 'SAUCE' or the record is not a valid SAUCE record. Version 2 Character 00 Version number of SAUCE. Current version is '00'. As new features are added to the specifications of SAUCE, this version number will change. Future versions SHOULD remain compatible with version 00 only ADDING on the specifications, it is however not unlikely that this compatibility is impossible to maintain, but this is of no concern now. Title 35 Character 00 Title of the file. Author 20 Character 00 Name or handle of the creator of the file. Group 20 Character 00 Name of the group/company the creator is employed by. Date 8 Character 00 Date the file was created. This date is in the format CCYYMMDD (Century, year, month, day). By storing it in this way, it's very easy to sort SAUCE records by date. FileSize 4 Long 00 Original filesize NOT including any information of SAUCE. DataType 1 Byte 00 Type of Data. (See DATATYPES further on) FileType 1 Byte 00 Type of File. (See DATATYPES further on) TInfo1 2 Word 00 Numeric information field 1 (See DATATYPES) When used, this field holds informative values. Any program using SAUCE should not rely on these values being correct or filled in. TInfo2 2 Word 00 Numeric information field 2 (See DATATYPES) TInfo3 2 Word 00 Numeric information field 3 (See DATATYPES) TInfo4 2 Word 00 Numeric information field 4 (See DATATYPES) Comments 1 Byte 00 Number of Comment lines (See COMMENTS) Flags 1 Byte * 00 Flags indication optional settings/switches These flags have different meaning depending on the datatype & filetype . The flags weren't originally in the concept for version 00 of SAUCE. But since the specification of SAUCE expects all filler bytes to be binary zero, the flags should be set to ZERO in all previous files, and cause no harm. An Example PASCAL record looks like this: TYPE SAUCERec = RECORD ID : Array[1..5] of Char; Version : Array[1..2] of Char; Title : Array[1..35] of Char; Author : Array[1..20] of Char; Group : Array[1..20] of Char; Date : Array[1..8] of Char; FileSize : Longint; DataType : Byte; FileType : Byte; TInfo1 : Word; TInfo2 : Word; TInfo3 : Word; TInfo4 : Word; Comments : Byte; Flags : Byte; Filler : Array[1..22] of Char; END; An Example C record looks like this: typedef SAUCEREC { char ID[5]; char Version[2]; char Title[35]; char Author[20]; char Group[20]; char Date[8]; signed long FileSize; unsigned char DataType; unsigned char FileType; unsigned short TInfo1; unsigned short TInfo2; unsigned short TInfo3; unsigned short TInfo4; unsigned char Comments; unsigned char Flags; char Filler[22]; } SAUCEREC; DATATYPES --------- DataType and FileType hold the information needed to deter- mine what type of file it is. There are 5 DataTypes, these are (with their respective numeric values) : 0) None : Undefined filetype, you could use this to add SAUCE information to personal datafiles needed by programs, but not having any other meaning. 1) Character : Any character based file. Examples are ASCII, ANSi and RIP. 2) Graphics : Any bitmap graphic file. Examples are GIF, LBM, and PCX. 3) Vector : Any vector based graphic file. Examples are DXF and CAD files. 4) Sound : Any sound related file. Examples are samples, MOD files and MIDI. 5) BinaryText: This is RAW memory copy of a text screen. It's basically the BIN format you can save from whitin TheDraw. Each character is built up of two consecutive bytes. The first is the character to be displayed. The second is the Attribute byte. 6) XBIN : XBIN is the so called eXtended BIN format. It is similar to the BinaryText, but provides for fonts, palettes, and has built-in compression. 7) Archive : Any type of archive. Examples are ARC, ZIP, ARJ and LZH. 8) Executable: Any file that is executable. None ---- When using the 'None' datatype, you should have FileType set to zero also. This is a compatibility issue as it's not unlikely, the 'None' datatype will have filetypes in the future. Character --------- When using the 'Character' datatype, you have following filetypes available : 0) ASCII : Plain text file with no formatting codes or color codes. TInfo1 is used for the width of the file. TInfo2 is used to hold the number of lines in the file. 1) ANSi : ANSi file. With ANSi color codes and cursor positioning. TInfo1 is used for the width of the file. TInfo2 is used to hold the number of ANSi screen lines in the file. 2) ANSiMation: ANSi Animation. With ANSi color codes and cursor positioning. While an ANSi file can also have animated sequences, there is a clear distinction. While an ANSi may or may not have a beginning animated sequence introducing the group or artist the rest is just a sequence of colored characters. An ANSiMation on the other hand is a more like a text mode cartoon. TInfo1 is used for the width of the file. TInfo2 is used to hold the number of ANSi screen lines the ANSiMation was created for. A program using SAUCE may use these two values to switch to the appropriate video mode. 3) RIP : Remote Imaging Protocol (RIP) graphics file. TInfo1 holds the width (should be 640) TInfo2 holds the height (should be 350) TInfo3 holds the number of colors (should be 16) 4) PCBoard : File with PCBoard style @X color codes and @ macro's and ANSi codes. TInfo1 is used for the width of the file. TInfo2 is used to hold the number of ANSi screen lines in the file. 5) AVATAR : A file with AVATAR and ANSi color codes and cursor positioning. 6) HTML : HyperText Markup Language. The type of file used on World Wide Web (WWW). 7) SOURCE : A piece of sourcecode for any type of programming language. The file extention should determine the programming language (.C=C, .PAS=Pascal, ...)

A) Non-Blink mode (iCE Color). When this bit is SET (equal to 1) The ANSi is created using iCE color codes. This is a special mode where the blinking is disabled, and you have 16 background colors available. Basically, you have the same choice for background colors as for foreground colors. Please note: When the picture does not make specific use of the iCE color, you should NOT have this bit set. When you do not support the iCE color mode, you should probably not display the file as it could look pretty weird in normal mode.

BinaryText ---------- The Binary Text format, basically has no Filetype, since the datatype has already defined how the file will look. The FileType however specifies the WIDTH of the BinaryText screen. Only the Width is required, as the Height can be calculated by dividing the filesize by the Width. In an attempt to provide as much WIDTH as possible in a possible 256 values of the Byte-sized FileType. The width is specified in Multiples of 2. The fact that the Width is specified in multiples of 2 isn't really a problem, since you also need to define the effective screen size in multiples of 2. An example : For normal 80*25 binary images as made with TheDraw the FileType value would be 40 (since 2*40 equals 80 ) All you need to do is divide the width of the binary text image by 2. This gives a maximum width of 510 characters. Although currently not supported, should there be a need for even bigger images, this can be arranged. Please note. BinaryText expects the character-attribute pairs to be stored one row at a time. If you wanted to create a 80*100 Image, you could do this by just copying 4 80*25 or 2 80*50 together to form one bigger image. If for example you wanted to create a 160*25 image from 2 80*25 images, you would need to write a little program which would copy line 1 from image 1, line 1 from image 2, Line 2 from Image 1, Line 2 from Image 2 and so on. Basically, you should have all character-attribute pairs from one line of the COMPLETE image one after the other, followed by all char-attribute pairs from the next row, and so on. If the picture does not fit this format. You should use the NONE datatype. Besides, you'd probably want to have it in this format anyway, as it seems to be the most logical approach to have these kind of images.

A) Non-blink mode (iCE Color). This bit has exactly the same meaning as for the Character datatype. It indicates whether the picture uses iCE color. XBIN ---- The XBIN datatype has no other filetypes. Further specification son the XBIN format are available in the XBIN archive or on the XBIN Web page. The filetype should be zero. TInfo1 holds width of the image, TInfo2 holds the Height of the image. FLAGS ----- Not used, should be all zeroes.

COMMENTS -------- The comment block is an addition to the SAUCE record. It holds up to 255 lines of additional information. Each line 64 characters wide. When the Comments field is not zero, it holds the number of additional comment lines available. A single comment line is 64 characters long. Like the character fields in the SAUCE record, it is padded with spaces, and has no leading length byte or trailing null-byte. The comment block is preceded with a 5 character identifi- cation mark.
