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.
