# See LICENSE.txt for license details.
# This file contains code that creates a few new statements. We'll
# also describe here the API for defining your own statements.
#
# Statements can be defined by calling renpy.statements.register. This
# function takes a string giving the keywords at the start of the
# statement, and then up to 4 functions defining the behavior of the
# statement: parse, execute, predict, and lint
#
# The parse function takes a lexer object as an argument, and is
# expected to return some parser data. The lexer has the following
# methods.
#
# l.eol() - True if we are at the end of the line.
# l.match(re) - Matches an arbitrary regexp string.
# l.keyword(s) - Matches s.
# l.name() - Matches any non-keyword name. Note that this only
# counts built-in keywords.
# l.word() - Matches any word, period.
# l.string() - Matches a renpy string.
# l.integer() - Matches an integer, returns a string containing the
# integer.
# l.float() - Matches a floating point number.
# l.simple_expression() - Matches a simple python expression, returns
# it as a string.
# l.rest() - Skips whitespace, then returns the rest of the line.
# l.checkpoint() - Returns an opaque object representing the current
# point in the parse.
# l.revert(o) - Given the object returned by l.checkpoint(), returns
# there.
#
# The parse function is expected to return an object, which is passed
# to the other functions. Parse should call renpy.error with the error
# message to report an error.
#
# The execute function is passed the object returned from parse, and
# is expected to execute the statement.
#
# The predict function is passed the object returned from parse, and
# is expected to return a list of images that are used by the
# statement.
#
# The lint function is called at lint time, after the init code is
# run. It should check the statement for errors, and report them by
# calling renpy.error with the appropriate error message.
#
# The scry function is called with a scry object. It may mutate that
# object, but it is then expected to return it. See 00nvlmode.rpy for
# details.
#
# The next function is expected to return a string giving the label of
# the next statement to execute, or None to indicate that next
# statement in the block should be executed. The next function is
# called during predict, scry, and execute, and should always return
# the same value. (Or scrying may be incorrect.)
