Enumeration Type Documentation

◆ thstrict_t

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

◆ th_isaccept()

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.

◆ th_validate()

int th_validate ( struct thcell_t  context,
thchar_t  c,
struct thinpconv_t conv 
)

Check and try to correct input sequence with default strictness.

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 at default strictness level, and do some convenient correction in conv.

◆ th_validate_leveled()

int th_validate_leveled ( struct thcell_t  context,
thchar_t  c,
struct thinpconv_t conv,
thstrict_t  s 
)

Check and try to correct input sequence.

Parameters
context: previous cell
c: the newly input character
conv: the storage for resulting correction info
s: strictness level
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 at strictness level s, and do some convenient correction in conv.
