It gets processed by 16 // a script to simulate `jagged arrays', with enumeration values holding 17 // offsets into the arrays. 18 // 19 // The format of the file is rather simple: A section starts with three 20 // labels separated by whitespace and followed by a colon (everything in a 21 // single line); the first label gives the name of the enumeration template, 22 // the second the name of the array template, and the third the name of the 23 // `maximum' template. The script then fills the corresponding templates 24 // (indicated by `@' characters around the name). 25 // 26 // A section contains one or more data records. Each data record consists 27 // of two or more lines. The first line holds the enumeration name, and the 28 // remaining lines the corresponding array data. 29 // 30 // There are two possible representations for array data. 31 // 32 // - A string of characters or character clusters (for example, representing 33 // Aksharas, Devanagari syllables) in UTF-8 encoding enclosed in double 34 // quotes, using C syntax, where the elements are separated by spaces. 35 // There can be only one string per line, thus the starting and ending 36 // double quote must be the first and last character in the line, 37 // respectively, ignoring whitespace before and after the string. If 38 // there are multiple strings (in multiple lines), they are concatenated 39 // to a single string. In the output, a string gets represented as a 40 // series of singles bytes, followed by a zero byte. The enumeration 41 // values simply hold byte offsets to the start of the corresponding 42 // strings. 43 // 44 // For strings, the `maximum' template holds the maximum number of 45 // non-space characters in all strings. 46 // 47 // - Data blocks enclosed in balanced braces, which get copied verbatim and 48 // which can span multiple lines. The opening brace of a block must be 49 // the first character of a line (ignoring whitespace), and the closing 50 // brace the last (ignoring whitespace also). The script appends a comma 51 // character after each block and counts the number of blocks to set the 52 // enumeration values. 53 // 54 // For data blocks, the `maximum' template holds the maximum number of 55 // array elements. 56 // 57 // A section can contain either strings only or data blocks only. 58 // 59 // A comment line starts with `//'; it gets removed. A preprocessor 60 // directive line (using the standard syntax of `cpp') starts with `#' and 61 // gets copied verbatim to both the enumeration and the array. Whitespace 62 // outside of a string is insignificant. 63 // 64 // Preprocessor directives are ignored while the script computes maximum 65 // values; this essentially means that the maximum values can easily be too 66 // large. Given that the purpose of those values is to create local 67 // fixed-size arrays at compile time for further processing of the blue zone 68 // data, this isn't a problem. Note the final zero byte of a string is not 69 // counted. Note also that the count holds the number of UTF-8 encoded 70 // characters, not bytes. 71 72 73 // The blue zone string data, to be used in the blue stringsets below. 74 75 AF_BLUE_STRING_ENUM AF_BLUE_STRINGS_ARRAY AF_BLUE_STRING_MAX_LEN: 76 77 AF_BLUE_STRING_ARABIC_TOP 78 " " 79 AF_BLUE_STRING_ARABIC_BOTTOM 80 " " 81 // We don't necessarily have access to medial forms via Unicode in case 82 // Arabic presentational forms are missing.
