Prohibit break between Thai/Alpha and Percent

LB24 of UAX#14 prohibits break between AL and PO,
	and between PO and AL, without example. But cases like
	"ten%" can be found in the internet, and similar usage
	like "สิบ%" sounds sensible in Thai.

* tests/test_thbrk.c (TestSamples):
	  - Add test case
	* src/thbrk/brk-ctype.c (_break_table):
	  - (THAI, NUM_NBB): _A -> _I
	  - (ALPHA, NUM_NBB): _A -> _I

2021-03-19  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit break between Currency and Alpha

LB24 of UAX#14 prohibits break between PR and AL,
	and between AL and PR, without example. But some cases
	can be found from Wikipedia:
	  - Brazilian real (usually written as R$)
	  - Nicaraguan córdoba (usually written as C$)
	  - Other uses: Micro$oft, George Luca$, etc.
	https://en.wikipedia.org/wiki/Dollar_sign

Similar usage is not clear for Thai.

* tests/test_thbrk.c (TestSamples):
	  - Add test case, with "C++" to catch side-effect of PR and PR
	* src/thbrk/brk-ctype.c (_break_table):
	  - (ALPHA, NUM_CUR): _A -> _I
	  - (NUM_CUR, ALPHA): _A -> _I
	  - (NUM_CUR, NUM_CUR): _A -> _I

2021-03-15  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit break on the other side of parentesis

LB30 of UAX#14 prohibits break in "(s)he" and "person(s)".
	The rule for Thai is more complicated. So, we only cover
	Latin for now.

* tests/test_thbrk.c (TestSamples):
	  - Add test case
	* src/thbrk/brk-ctype.c (_break_table):
	  - (ALPHA, NBA): _A -> _I
	  - (CLOSE, ALPHA): _A -> _I

2021-03-09  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit break between Thai/Alpha and number

LB23 of UAX#14 prohibits break between AL and NU, and between
	NU and AL. This makes sense for Latin. For Thai, prohibiting
	break between AL and NU makes sense for codes like "กข43"
	as a rice strain, but "40บาท" should still be broken.

* tests/test_thbrk.c (TestSamples):
	  - Add test case
	* src/thbrk/brk-ctype.c (_break_table):
	  - (ALPHA, NUM): _A -> _I
	  - (NUM, ALPHA): _A -> _I
	  - (THAI, NUM): _A -> _I

2021-03-05  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Handle Latin acronyms

LB29 of UAX#14 prohibits break between IS and AL for acronyms
	such as "e.g.", but this causes side-effects on other IS
	punctuations like comma, colon, semicolon as well. This leads
	to an error in case of ",ก" in Unicode LineBreakTest.txt
	as tested by Pango, which I think it makes perfect sense
	to allow break. So, I'm not trying to fix it, but try to
	extend acronym handling to cover Latin instead.

* tests/test_thbrk.c (TestSamples):
	  - Add test case
	* src/thbrk/thbrk.c (th_brk_find_breaks):
	  - Rename 'thai_chunk' variable to 'chunk'.
	  - Move brk_op() lookup to after chunk handling.
	  - Adjust acronym handling to cover BRK_CLASS_ALPHA acronyms.
	  - Reset chunk pointers every time break class changes,
	    not just when entering Thai chunk.

2021-03-01  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit some breaks around number sign

UAX#14 prohibits break within "#ก", which makes sense for
	hashtags, but its classification as AL would affect cases
	like "hello|สวัสดี". So, re-classify it as QUOTE instead.

* tests/test_thbrk.c (TestSamples):
	  - Add test cases
	* src/thbrk/brk-ctype.c (_char_class):
	  - Change class of '#' from BRK_CLASS_ALPHA to BRK_CLASS_QUOTE.

Partially addresses issue #6.

2021-02-22  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit break between right parenthesis and currency

It's common to write "12๎๎฿" instead of "฿12". So, line break
	between right parenthesis and currency, such as in "(12)฿",
	should be prohibited similarly to the left-side form.

* tests/test_thbrk.c (TestSamples):
	  - Add test cases
	* src/thbrk/brk-ctype.h (brk_class_t):
	  - Add BRK_CLASS_CLOSE to separate ')', ']', '}' from BRK_CLASS_NBB.
	* src/thbrk/brk-ctype.c (_char_class):
	  - Change class of ')', ']', '}' from BRK_CLASS_NBB to
	    BRK_CLASS_CLOSE.
	* src/thbrk/brk-ctype.c (_break_table):
	  - Insert row and column for CLOSE, with contents copied from NBB.
	  - Change (CLOSE, NUM_CUR): _A -> _P

2021-02-19  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohibit break between currency and left parenthesis

In UAX#14, although LB18 (break after spaces) makes prohibited breaks
	between PR and {NU,OP} in LB25 equivalent to indirect breaks,
	the description of PR Property insists that it must be prohibited
	"even if a space character intervenes", with "$ (100.00)"
	as an example with no break opportunity. [1] So, we take them as
	prohibited breaks.

[1] https://www.unicode.org/reports/tr14/#PR

* tests/test_thbrk.c (TestSamples):
	  - Add test case as interpreted from UAX#14
	* src/thbrk/brk-ctype.c (_break_table):
	  - (NUM_CUR, NBA): _A -> _P

2021-02-18  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Prohitbit 2 break cases before percent

In UAX#14, although LB18 (break after spaces) makes prohibited breaks
	between {NU,CL,CP} and PO in LB25 equivalent to indirect breaks,
	the description of PO Property insists that it must be prohibited
	"even if one or more space characters intervene", with "(12.00) %"
	as an example with no break opportunity. [1] So, we take them as
	prohibited breaks.

[1] https://www.unicode.org/reports/tr14/#PO

* tests/test_thbrk.c (TestSamples):
	  - Add test case as interpreted from UAX#14
	* src/thbrk/brk-ctype.c (_break_table):
	  - (NUM, NUM_NBB): _I -> _P
	  - (NBB, NUM_NBB): _A -> _P

2021-02-14  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Rewrite thbrk test for extensibility.

* tests/test_thbrk.c:
	  - Rewrite to read and test from sample list.
	  - Encode samples in UTF-8 and convert them as required.

2021-02-14  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Simplify thbrk test.

* tests/test_thbrk.c:
	  - Remove interactive mode.
	  - Continue testing, rather than exit, on failures.

2021-02-05  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Provide our own version of INSTALL instruction.

* INSTALL:
	  - Explain simple installation steps and build requirements.
	* .gitignore:
	  - Remove INSTALL ignoring.

This is to address a frequently found issue when
	'autoconf-archive' is missing, like in issue #9.

2021-01-28  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Another protection against invalid array access.

In addition to commit 8e7ab6967f862a409352f7e8985fd4b445d37f4d.

* src/thbrk/thbrk.c (th_brk_find_breaks):
	  - Protect against accessing pos[-1] which may be caused by
	    a failure in brk_maximal_do().

Thanks Ratchanan Srirattanamet for the report via personal mail.

	  - Instead of preparing full path name with snprintf(), which is
	    non-ANSI, and still risks path name trimming, do it with

Use 'wc' prefix instead of suffix for wide-char word break APIs.

2016-06-25  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Rename the new APIs to be more meaningful.

The methods for ThBrk I proposed to Mark Brown in our discussion
	were too confusing. Before they get public, let's pick more
	meaningful names instead:
	  - th_brk_brk()       -> th_brk_find_breaks()
	  - th_brk_brk_line()  -> th_brk_insert_breaks()
	  - th_brk_wbrk()      -> th_brk_find_breaks_wc()

Implement a new thread-safe interface for word break.

To achieve more thread-safety without depending on mutex mechanisms,
	a new set of APIs is added so that the client can create
	a shared instance of word break engine by him/herself
	under appropriate mutex. Then, the word break functions
	can be safely called in parallel using the shared engine.

* src/thbrk/brk-common.h, src/thbrk/brk-common.c

	    ThBrk implementation in ThBrk layer instead.
	  - The logic for finding and loading dictionary at
	    default paths is still retained here.

* src/thbrk/thbrk.c (th_brk_new, th_brk_delete):

	    at specified path or at default paths if not specified.

* src/thbrk/brk-maximal.h, src/thbrk/brk-maximal.c
	  (struct _BrkEnv, brk_env_new):

Share BrkEnv longer.

The code before the threadsafe commit used to initialize the
	free list earlier in th_brk() and then called brk_maximal_do()
	multiple times. This allowed the free list to be shared among
	all such calls. The threadsafe commit did it deep in
	brk_maximal_do_impl(), limiting the share within the single
	brk_maximal_do() call only. We should widen the use to be
	the same as previously done.

* src/thbrk/brk-maximal.h (+brk_env_new, +brk_env_free):
	  - Re-add initialization/quit functions in terms of BrkEnv.
	  - Add BrkEnv* arg to brk_maximal_do().
	* src/thbrk/brk-maximal.c (brk_env_init -> brk_env_new,
	  brk_env_destroy -> brk_env_free):
	  - Turn the init/destroy functions into new/free version.
	* src/thbrk/brk-maximal.c (brk_maximal_do, brk_maximal_do_impl):
	  - Add the BrkEnv* arg and use it instead of the locally created
	    one.
	* src/thbrk/thbrk.c (th_brk):
	  - Create BrkEnv object at start and free it at end.
	  - Add the env arg to brk_maximal_do() calls.

This appears to save more 2.4% of the total runtime and makes
	it on par with the code before the threadsafe commit again.

2015-10-14  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Call brk_pool_match() linearly.

* src/thbrk/brk-maximal.c (brk_maximal_do_impl, brk_recover_try):
	  - Start next brk_pool_match() on node next to previously matched
	    one, instead of the pool head, making the match O(n) instead of
	    O(n^2).
	  - [brk_maximal_do_impl] Also prevent using the deleted node to
	    start the next round.
	  - [brk_recover_try] Also start brk_pool_delete_node() on the
	    pool tail, making it also linear. This is not possible for
	    brk_maximal_do_impl, as the node to be deleted is not fixed.

This appears to save time by 8.85% on brk_pool_match() calls,
	lowering its bottleneck rank by 2 positions, and saves time by
	0.0388% of total run time.

2015-10-14  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Declare variable inside block.

* src/thbrk/brk-maximal.c (brk_maximal_do_impl, brk_recover_try):

Declare const arg for brk_pool_match().

* src/thbrk/brk-maximal.c (brk_pool_match):

2015-10-11  Theppitak Karoonboonyanan  <theppitak@gmail.com>

Minor optimization on brk_pool_match().

Callgrind reports brk_pool_match() among top bottlenecks.
	So, try to optimize it as we can.

* src/thbrk/brk-maximal.c (brk_pool_match):
	  - Instead of sharing the loop for two different cases,
	    check the case once and run loop for each case separately,
	    to minimize branching down to a single time.
	  - Evaluate the unchanged 'node->shot.brk_pos[node_cur_pos - 1]'
	    expression only once, instead of on every round.

This appears to save time by 9.3% for total brk_pool_match() calls,
	and by 0.067% of total run time.

Replace static global free-list with local one.

The static global free-list in brk-maximal.c makes it not
	thread-safe.

* src/thbrk/brk-maximal.c:
	  - Add type BrkEnv to keep break pool free list, with
	    brk_env_init() and brk_env_destroy() methods.
	  - (brk_pool_node_new, brk_pool_node_free, brk_pool_free,
	     brk_pool_delete, brk_root_pool, brk_recover_try,
	     brk_recover):
	    Add (BrkEnv *) arg to relevant functions and use it properly.
	  - (brk_maximal_do):
	    Create and destroy BrkEnv instance for use locally.
	    Pass it to the required function calls.
	  - (brk_pool_delete -> brk_pool_delete_node):
	    Rename function to avoid confusion with brk_pool_free().

* src/thbrk/brk-maximal.c:
	* src/thbrk/brk-maximal.h:
	* src/thbrk/thbrk.c:
	  - Get rid of now-unnecessary brk_maximal_init() and

* src/thbrk/brk-maximal.c (brk_maximal_do_impl, best_brk_contest): 
	Back out weighted scoring for solution contest, as it sometimes tries
	too hard to minimize word count, even though another solution with more
	known words can match more text and results in smaller unknown zone.
	Accidental words problem, which this scheme tried to address, has
	already been alleviated with increased recovery threshold.

2009-06-17  Theppitak Karoonboonyanan  <thep@linux.thai.net>

* src/thbrk/brk-maximal.c (brk_maximal_do_impl): Add break pos at
	string end and let it enter the contest, instead of backing it out by
	moving back str_pos as done in previous commit. That commit just
	missed the point. Doing the right thing also guarantees consistency
	with the case when some text of valid words is appended to the string.

2009-06-17  Theppitak Karoonboonyanan  <thep@linux.thai.net>

* src/thbrk/brk-maximal.c (brk_maximal_do_impl): Set str_pos for cases
	that fail at string end back to the last progress position, to prevent

* src/tkbrk/brk-maximal.c (RECOVERED_WORDS): Increase recovery

	easily.
