thai/thinp.h - Thai string input sequence filtering. SYNOPSIS
Data Structures struct thinpconv_t Input sequence correction info. Enumerations enum thstrict_t { ISC_PASSTHROUGH = 0, ISC_BASICCHECK = 1, ISC_STRICT = 2 } Strictness of input sequence checking, according to WTT 2.0. Functions int th_isaccept (thchar_t c1, thchar_t c2, thstrict_t s) Check for acceptance of input sequence. int th_validate (struct thcell_t context, thchar_t c, struct thinpconv_t *conv) Check and try to correct input sequence. Detailed Description Thai string input sequence filtering. Enumeration Type Documentation enum thstrict_t Strictness of input sequence checking, according to WTT 2.0. Enumerator ISC_PASSTHROUGH No check ISC_BASICCHECK Basic check ISC_STRICT Strict check Function Documentation int th_isaccept (thchar_tc1, thchar_tc2, thstrict_ts) Check for acceptance of input sequence. Parameters: c1 : previous character c2 : the newly input character s : strictness level Returns: non-zero if accepted, 0 otherwise Checks if, according to WTT 2.0 strictness level s, c2 is allowed after c1. int th_validate (struct thcell_tcontext, thchar_tc, struct thinpconv_t *conv) Check and try to correct input sequence. Parameters: context : previous cell c : the newly input character conv : the storage for resulting correction info Returns: 0 if the input is to be rejected non-zero otherwise. Given the previous cell as context, edit the input buffer using the given input c, maintaining WTT canonical order, and do some convenient correction in conv.

thai/wtt.h - WTT I/O implementation. SYNOPSIS
Enumerations enum WTTClass { CTRL = 0, NON = 1, CONS = 2, LV = 3, FV1 = 4, FV2 = 5, FV3 = 6, BV1 = 7, BV2 = 8, BD = 9, TONE = 10, AD1 = 11, AD2 = 12, AD3 = 13, AV1 = 14, AV2 = 15, AV3 = 16 } Classification of characters in TIS620 according to WTT. enum WTTOp { CP = 1, XC = 2, AC = 3, RJ = 4, SR = 5 } Composibility checking tables. Functions WTTClass TACchtype (thchar_t c) WTT character class. WTTOp TACio_op (thchar_t c1, thchar_t c2) WTT I/O operation. Detailed Description WTT I/O implementation. WTT stands for Wing Tuk Tee (in Thai, Runs everywhere). It was defined by TACTIS (Thai API Consortium/Thai Industrial Standard) in the NECTEC Thai Software Standard Project (1989-1991), and later endorsed by Thai Industrial Standard Institute (TISI) as TIS 1566-2541 in 1998. WTT classifies Thai chracter(TIS-620) into 17 types below. ITYPE VALUE SHORT_DESCRIPTION CTRL 0 control characters NON 1 non composible characters CONS 2 consonants LV 3 leading vowels FV1 4 following vowels 1 FV2 5 following vowels 2 FV3 6 following vowels 3 BV1 7 below vowels 1 BV2 8 below vowels 2 BD 9 below diacritics TONE 10 tonemarks AD1 11 above diacritics 1 AD2 12 above diacritics 2 AD3 13 above diacritics 3 AV1 14 above vowels 1 AV2 15 above vowels 2 AV3 16 above vowels 3 Functions in thctype.h do basic character classifications while wtt.h classifies a chracter in detail. Please refer to the reference. TACio_op() checks how to compose two given chracters. The possiblities are Composible (CP), Non-display (XC), Accept (AC), Reject (RJ) and Strict Reject (SR). The values of CP, XC, AC, RJ and SR are difined in wtt.h. And their meanings are: o CP : second character is displayed in the same cell as the first, also implies an acceptance. o XC : Do nothing. o AC : Display second character in the next cell. o RJ : Discard second character. o SR : Reject second character only in strict mode. Enumeration Type Documentation enum WTTClass Classification of characters in TIS620 according to WTT. Enumerator CTRL control chars NON non composibles CONS consonants LV leading vowels FV1 following vowels 1 FV2 following vowels 2 FV3 following vowels 3 BV1 below vowels 1 BV2 below vowels 2 BD below diacritics TONE tonemarks AD1 above diacritics 1 AD2 above diacritics 2 AD3 above diacritics 3 AV1 above vowels 1 AV2 above vowels 2 AV3 above vowels 3 enum WTTOp Composibility checking tables. Enumerator CP COMPOSIBLE - following char is displayed in the same cell as leading char, also implies ACCEPT XC Non-display AC ACCEPT - display the following char in the next cell RJ REJECT - discard that following char, ignore it SR STRICT REJECT - REJECT only if in strict mode Function Documentation WTTClass TACchtype (thchar_tc) WTT character class. Parameters: c : the character Returns: WTT character class { CTRL, ..., AV3 } WTTOp TACio_op (thchar_tc1, thchar_tc2) WTT I/O operation. Parameters: c1 : previous character c2 : next character Returns: WTT I/O operation { CP, XC, AC, RJ, SR } Author Generated automatically by Doxygen for libthai from the source code.
