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.
