2018-08-14  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Fix compiler warning on uncovered enum case.

	* src/filterrtf.cpp (FilterRTF::GetNextToken()):
	  - Add default: to switch(), to fix warning on uncovered enum.
	  - Remove an unnecessary break after goto.

2018-08-14  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Add comment for previous commit.

	* src/filterrtf.cpp (FilterRTF::chgCharState()):
	  - Add comment explaining unreachable line.

2018-08-14  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Drop unused CS_NONE ECharState in FilterRTF.

	The only place it's used is the return value of chgCharState()
	method, which has no chance to be reached, as the 'state' arg,
	which is from FilterRTF::psState, is never set to CS_NONE
	through out the code. So, all possible values have been covered
	in 'switch (state)' and compiler warning on uncovered CS_NONE
	is in fact meaningless.

	Besides, having a "none" value for a state in finite automaton
	is questionable. Is it a special dead state? No, it's never
	handled explicitly anyways.

	* src/filterrtf.h (FilterRTF::ECharState):
	  - Drop CS_NONE value.
	* src/filterrtf.cpp (FilterRTF::chgCharState()):
	  - Drop unreachable "return CS_NONE" statement.

2018-08-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Drop "#pragma once" in headers.

	It's not portable, and multiple include optimization
	in compilers just make "#ifndef" idiom have the same effect.

	    from start to end.

2017-11-24  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Merge loop in MaxWordSeg::saveSegment().

	* src/maxwordseg.cpp (MaxWordSeg::saveSegment()):
	  - Optimize array access using pointers.
	  - Merge extra iteration on the last element into the main loop,
	    checking for the terminator so iteration over the last
	    element is possible, and the split of the last element copying
	    from the rests before it is not necessary.

2017-11-23  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Only reverse word list on Thai chunks.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):

	  - Move private section to the end.

2017-11-22  Theppitak Karoonboonyanan <theppitak@gmail.com>

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Chain chunk type cases into a single if-else-statement,
	    instead of several if-statements with 'continue' at the end,
	    to clarify the classification checks.

2017-11-21  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Make WordSeg() internal functions private.

	* src/abswordseg.h:

	Rename AbsWordSeg::SwapLinkSep() to ReverseLinkSep().

	* src/abswordseg.h, src/abswordseg.cpp:
	  - Rename AbsWordSeg::SwapLinkSep() to ReverseLinkSep().

2017-11-21  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Remove empty default c-tors.

	* src/longwordseg.h, src/longwordseg.cpp:
	* src/maxwordseg.h, src/maxwordseg.cpp:

2017-11-20  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Simplify loop in MaxWordSeg::WordSegArea().

	* src/maxwordseg.cpp (MaxWordSeg::WordSegArea()):
	  - Rearrange loop for more readability.
	  - With this, foundUnk flag is eliminated.

2017-11-17  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Adjust MaxWordSeg::CreateSentence().

	* src/maxwordseg.cpp (MaxWordSeg::CreateSentence()):
	  - Assign stWord = i + 1 after unknown zone, to resemble
	    the case of in-dict word (where stWord is assigned 1, not 0).
	    Then, the later for-loop on stWord won't need to check and
	    increment stWord the first time, as we already know
	    LinkSep[IdxSep[stWord]] == enAmb, and the if-condition
	    within the for-loop will always fail in the first round.
	  - Drop unnecessary (stWord < textLen) check, as enAmb is assumed
	    to never exceed textLen, and thus (stWord < enAmb) should
	    alreader imply (stWord < textLen).
	  - Merge the (IdxSep[stWord] < 0) check into next if-condition.

2017-11-16  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Make LongWordSeg try other paths than just the first.

	* src/longwordseg.cpp (LongWordSeg::CreateSentence()):
	  - Wrap the text iteration loop with backtrack loop,
	    employing the BackTrackStack.
	  - Keep track of unknown word count.
	  - Return immediately if text end is reached with zero unknown.
	  - Otherwise, try to find the best sentence with least unknowns.

2017-11-15  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Simplify LongWordSeg::CreateSentence().

	* src/longwordseg.cpp (LongWordSeg::CreateSentence()):
	  - Use intermediate WordState instantiation and get rid of
	    wState var.
	  - Move common SepData[senIdx].Sep[sepIdx] assignments out of
	    the cases of 'if (IdxSep[Idx] >= 0)' block.
	  - Do not check Idx against textLen inside the while-loop,
	    which already checks the same condition.
	  - Move common SepData[senIdx].Sep[sepIdx] terminator assignments
	    out of the cases of 'if (SepData[senIdx].Sep[sepIdx - 1]
	    == textLen)' block.

2017-11-15  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Capitalize wordState type.

	* src/worddef.h:
	* src/wordstack.h:
	* src/longwordseg.cpp:
	* src/maxwordseg.cpp:
	  - Rename wordState type to WordState.

2017-11-15  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Add test in which long and max results differ.

	* tests/test-simple.sh:
	  - Add test case in which longest matching and maximal matching
	    schemes yield different results.
	  - Also print input string on each test step for debugging.

2017-11-11  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Add test for longest matching scheme to all tests.

	* tests/test-simple.sh:
	* tests/test-long.sh:
	* tests/test-mixed.sh:
	* tests/test-utf8-wbr.sh:
	* tests/test-latex.sh:
	  - Repeat all tests one more time, with different -m option.
	    (This seems to catch an error on longest matching.)

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Remove excessive LinkSep terminator.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Remove extra LinkSep[] terminator assignment.
	    Only one is enough.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Adjust SwapLinkSep() loop more.

	* src/abswordseg.cpp (AbsWordSeg::SwapLinkSep()):
	  - Rename variables: st_idx -> start; en_idx -> end.
	  - Instead of saving 'end' and directly iterating on it,
	    define another 'upper' iterator for that purpose.
	    Then, 'end' value can be used at the end.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Simplify SwapLinkSep() loop.

	* src/abswordseg.cpp (AbsWordSeg::SwapLinkSep()):
	  - Move en_idx, end_point, tmp vars inside loop
	    where they are used. Only st_idx is left on top level.
	  - No more en_idx assignment at loop end.
	  - Stop en_idx exactly at LinkSep[] element with value -1,
	    not the one after.
	  - Simply assign end_point as saved storage of en_idx value.
	    No computation is needed.
	  - Simply decrement en_idx to get the last non-terminate element.
	    No confusing skip by 2.
	  - Simplify the swap code inside inner while-loop.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Set IdxSep[] on every char instead of relying on defaults.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Instead of skipping IdxSep[i] assignments and relying on
	    initial values on some chars, let's assign them explicitly.

	* src/abswordseg.cpp (AbsWordSeg::WordSeg()):
	  - Remove now-unneeded InitData() call.
	* src/abswordseg.h, src/abswordseg.cpp (-AbsWordSeg::InitData()):
	  - Remove now-unneeded InitData() method.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Add test for mixed text.

	* tests/Makefile.am,
	  +tests/test-mixed.sh, +tests/mixed.txt, +tests/mixed-wseg.txt:
	  - Add test case for text mixed with English text, digits,
	    Thai digits.
	* tests/Makefile.am:
	  - Clear test outputs on 'clean' instead of 'distclean'.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Replace for-loop with while-loop.

	text[i] iteration has irregular increments, as decrements
	before continue appear in many places. This indicates
	improper use of for-loop.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Replace for-loop with while-loop, and increment the iterator
	    as actually required.
	  - Remove unnecessary decrements.
	  - Rewrite comments and regroup source lines.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Adjust IdxSep[] and LinkSep[] settings in Thai chunk.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Replace cntFound counter with bool isWordFound.
	  - Initialize IdxSep[i] = -1 and overwrite it later,
	    instead of setting it afterward when no word is found.
	  - Always add terminating element to LinkSep[] in case
	    word is found, regardless of whether the word count is
	    below 2000. (Weird limit value.)
	  - Remove now-unnecessary LinkSep[cntLink] = -1 assignment
	    on pseudo-ending element.

2017-11-10  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Simplify word list preparation loop within Thai chunk.

	* src/abswordseg.cpp (AbsWordSeg::CreateWordList()):
	  - Iterate j from i to textLen instead of from 0 to (textLen - i)
	    and then simply access text[j] instead of text[i + j].
	  - Rearrange IdxSep[i] assignment and cntFound increment,
	    for more readability.
	  - Adjust LinkSep[cntLink] assignments logic to resemble those in
	    other codes.

2017-11-09  Theppitak Karoonboonyanan <theppitak@gmail.com>

	Refactor dictionary out of AbsWordSeg.

	    TrieState.
	  - Move AbsWordSeg::InitDict() functionality into Dict::open().
	  - Remove AbsWordSeg::MyDict member.
	* src/abswordseg.h, src/abswordseg.cpp:
	  - Add dict arg to AbsWordSeg::WordSeg() and
	    AbsWordSeg::CreateWordList(), and use it instead of
	    the old MyDict.
	  - Replace TrieState type with Dict::State.

	* src/wordseg.cpp:
	  - [InitWordSegmentation(), +OpenDict()] Split dictionary opening
	    into a separate function, and simplify the rest code.
	  - [main()] Define Dict local instance and call OpenDict() upon it.
	    Drop dictpath parameter from InitWordSegmentation() call.
	  - [WordSegmentation()] Add dict arg and pass it on to
	    AbsWordSeg::WordSeg().
	  - [main()] Add dict parameter to WordSegmentation() calls,
	    as now required.

	As an adjustment to issue #1 fix, taking the word break string
	in output encoding should be more sensible to users than in
	input encoding, so s/he can directly specify the string to insert.

	* src/wordseg.cpp (main):

2013-12-20  Theppitak Karoonboonyanan  <thep@linux.thai.net>

	Fix off-by-one character loss in long HTML token.

	* src/filterhtml.cpp (FilterHtml::GetNextToken):
	  - On verge of full buffer, jump to 'chbuff' storing stage,
	    rather than just quitting the loop, so the first character
	    of the next part of the long token is not lost.
	  - Also decrement 'tokenSz' on first character. Missing this
	    could cause buffer overflow.

	Thanks Nicolas Brouard for the report.

	  - Rewrite ConvGetS(), ConvGetC() to return wchar_t (string).
	  - Add ConvPrint() for printing wchar_t string as given encoding
	    scheme (UTF-8/TIS-620).
	  - Add Ascii2WcsCopy() and Ascii2WcsCat() for transferring between
	    ASCII char/wchar_t arrays.

	* src/wordseg.cpp (main):
	  - Drop UTF-8 -> TIS-620 conversion as preprocessing and replace it
	    with ConvGetS(), which gives wchar_t string.
	  - Replace char arrays with wchar_t ones, along with all manipulations.
	* src/wordseg.cpp (WordSegmentation):
	  - Change args from char* to wchar_t*.
	  - No longer requires isUniOut arg, as it now only works on internal
	    UCS storage. The conversion is moved back to higher layer again.
	* src/wordseg.cpp (SplitToken):
	  - Change args from char* to wchar_t*.

	* src/abswordseg.h (class AbsWordSeg):
	  - Redeclare char -> wchar_t:

	    - IsLeadChar(), IsLastChar(), Has_Karun() args
	* src/abswordseg.cpp (CreateWordList, IsLeadChar, IsLastChar,
	  Has_Karun, WordSeg):

	  - Redeclare 'buffer' member as wchar_t array.
	* src/filterlatex.cpp (FilterLatex::GetNextToken):
	  - Replace char -> wchar_t, along with manipulations.
	* src/filterlatex.cpp (FilterLatex::Print):
	  - Ignore latexFlag case which calls AdjustText(). The shaping is
