NAME
thai/thinp.h -
Detailed Description
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.
Enumeration Type Documentation
Strictness of input sequence checking, according to WTT 2.0.
Enumerator:
ISC_BASICCHECK
Basic 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.
