# Thai-Latin
# This set of rules follows ISO 11940
#	see http://homepage.mac.com/sirbinks/pdf/Thai.r2.pdf
# except that that does not mention an implicit vowel, so we use ọ
#
# The transcription is fairly ugly, so we ought to also do the UNGEGN version
#	see: http://www.eki.ee/wgrs/rom1_th.pdf
# and probably make that the main variant.

# Note: this is an internal file. The NFD/NFC is handled externally, in the index
# The insertion of spaces between words, the reversal of the vowels
# and the conversion of space to semicolon are done *outside* of these rules.
# So as far as these rules are concerned, the vowels are in logical order!

# insert implicit vowel (and remove it going the other way)
# COMMENTED out: the implicit vowel positions cannot be predicted algorithmically
#$consonant = [ก-ฮ];
#$vowel = [ะ-ฺเ-ไ็];

#{ ( $consonant ) } [^$vowel ] > | $1  ;
# > ọ ;
# < ọ ;

$notAbove = [^\p{ccc=0}\p{ccc=above}] ;
$notBelow = [^\p{ccc=0}\p{ccc=below}] ;

# Consonants
# Warning: the 'h's need to be handled carefully!
# What we really want to say is the following, but we can't
# $notHAccent = !($notAbove*   ̄ | $notBelow*   ̣) ;

# Since the only accents we care about that could cause problems are free-standing accents below, we use instead:
$freeStandingBelow = [\u0325  ];
$hAccent =  [   ̄     ̣]
$notHAccent0 = [^$freeStandingBelow$hAccent];
$notHAccent1 = $freeStandingBelow [^$hAccent];
