d99a9cbce9 different handling of space tokens 
space tokens are now always attached to the previous non-space token
there are two exceptions:
leading space tokens are attached to the first following non-space token
in input that consists exclusively of space tokens, the last space token
is the head of all others.

04177debd0 * Unwind limit to sentence boundary detection that prevents it from inserting boundaries on whitespace. Replace it with a check for whitespace in StateClass.fast_forward, so that whitespace is LeftArced when it's on the stack. This should prevent the previous problem of whitespace-only sentences. Should fix Issue #184, but may cause further problems. Needs testing. 2016-01-19 02:54:15 +01:00

9dd2f25c74 * Fix Issue #131: Force whitespace characters to attach syntactically to previous token, and ensure they cannot serve as stand-alone 'sentence' units. 2015-10-10 15:53:30 +11:00

e29daea85f * Fix bint/int typing problem in TransitionSystem. In C++ bint* means bool*, but in C it means int*. So, type-casting to bint* is unsafe. 2015-07-17 22:37:24 +02:00
