[fU-cvs] ser-txt format extensions

[stephan b. <st...@ei...>]

okay, i've gotten carried away...

the ser-txt parser can now handle a more useful superset of the txt 
format. Here's an example which shows the current possibilities:


/*
        comment block
*/
// single-line comment
#  single-line comment
;  single-line comment
myfoo class=FooClass
{
        gameboxName G.E.V.
        gameboxVers = 0.1
// ^^^ optional = sign for property declarations.
        mybar class=BarClass
        {
                myprop 17
                myotherprop "this string here, seen?"
/***********
we don't serve their kind here:
                ohno class=NoExistie
                {
                        canyouinstantiateme = no
                        canyouinstantiateme2 = no2
                        canyouinstantiateme3 = no3
                }
                ohno class=NoExistie
                {
                        canyouinstantiateme = no
                }
                ohno class=NoExistie
                {
                        canyouinstantiateme = no
                }
***********/
        }
};
# ^^^ optional trailing semicolon

root_too class=FooClass
{
        the_real_node #42.42
 # strings: backslashes and outer quotes will get
# stripped and newlines normalized:
        quoted_string="this is a quoted string"
        unquoted_string this is an unquoted string
        squoted_string   'this is a \
			single-quoted \
		        string'
        mstring  "this is a \
                \"multi-line\" \
                string"

        another semi-colon val;
        key = semi-colon val;
# semicolon gets stripped.

        SOURCES = foo \
	elib_globals.cpp \
	ECommandLiner.cpp \
	EInputProcessor.cpp \
	EEnvironment.cpp \
	EInputProcessorChain.cpp \
	EInputDispatcher.cpp \
	EKeyValueParser.cpp  \
	ELib.cpp \
	EPointerList.cpp \
	ESimpleCLParser.cpp \
	EStdStringTokenizer.cpp \
	EStringTokenizer.cpp \
	EPathFinder.cpp \
	EPropertyList.cpp \
	EReadline.cpp \
	EShellProcess.cpp \
	EStringList.cpp

}


possible todos:

add protocol level check for, e.g.:
#SerialTree text_v2

     nodename class=Foo X
where X is some positive integer - the object would be replicated that 
number of times.

    # nodename class=Foo
comment out the whole node if the node decl is commented out.

i'll check this into the fun tree once i'm happy with it. The code does 
not yet build a proper tree (i'm using property lists for everything at 
the moment), but the parser is agnostic in regards to the tree 
structure, using a set of 3 callbacks to open/close nodes and add props 
to the current node.
