# ICU Break Iterator Rule Parser State Table
#
# This state table is used when reading and parsing a set of RBBI rules
# The rule parser uses a state machine; the data in this file define the
# state transitions that occur for each input character.
#
# *** This file defines the RBBI rule grammar. This is it.
# *** The determination of what is accepted is here.
#
# This file is processed by a perl script "rbbicst.pl" to produce initialized C arrays
# that are then built with the rule parser.
#
#
# Here is the syntax of the state definitions in this file:
#
#
#StateName:
# input-char n next-state ^push-state action
# input-char n next-state ^push-state action
# | | | | |
# | | | | |--- action to be performed by state machine
# | | | | See function RBBIRuleScanner::doParseActions()
# | | | |
# | | | |--- Push this named state onto the state stack.
# | | | Later, when next state is specified as "pop",
# | | | the pushed state will become the current state.
# | | |
# | | |--- Transition to this state if the current input character matches the input
# | | character or char class in the left hand column. "pop" causes the next
# | | state to be popped from the state stack.
# | |
# | |--- When making the state transition specified on this line, advance to the next
# | character from the input only if 'n' appears here.
# |
# |--- Character or named character classes to test for. If the current character being scanned
# matches, peform the actions and go to the state specified on this line.
# The input character is tested sequentally, in the order written. The characters and
# character classes tested for do not need to be mutually exclusive. The first match wins.
#
#
