# This file is to be processed with testgen.pl to produce test suites
|
||||
# for bindings. The only escape code that is valid is \x
|
||||
|
||||
# The only type that may change between bindings is "char", which gets
|
||||
# converted into the most convenient representation of a character in
|
||||
# a given language. In C, this is a TT_UINT; in P*, it's a
|
||||
# single-character string. In this file, a character is wrapped with
|
||||
# single quotes.
|
||||
|
||||
# Strings may be given in C syntax, with no escapes other than \xHH or
|
||||
# in hex syntax, like <31.32.33> for "123".
|
||||
|
||||
# indirect/bind_indirect can be used via subparsers. A subparser is
|
||||
# introduced with a "subparser $<name> = <definition()>;" command.
|
||||
# First, all subparsers are declared with h_indirect(). Then, they
|
||||
# are all bound. Inside a definition, all subparsers can be
|
||||
# referenced by $<name>.
