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_t  c1, thchar_t  c2, thstrict_t  s )

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_t  context, thchar_t  c, 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.
