[fU] text-mode parser: it's alive!

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

It works on basic inputs now, plus extends the format to include optional=
 =3D=20
signs between keys and values:


map class=3DYetAnotherNoopClass
{
        gameboxName=3DG.E.V.
        gameboxVers 0.1
        foo class=3Delib::NoClass
        {
                x novalue
                z true
        }
        asiz  =09=3D=09  529
        strval "this is a string"
# (doesn't handle multi-line string yet)

}

Will do the following:

main.cpp:52 : 1 Opening new node [YetAnotherNoopClass,nodename=3Dmap]
main.cpp:40 : 1 map: add_property(gameboxName,G.E.V.)
main.cpp:40 : 1 map: add_property(gameboxVers,0.1)
main.cpp:52 : 2     Opening new node [elib::NoClass,nodename=3Dfoo]
main.cpp:40 : 2     foo: add_property(x,novalue)
main.cpp:40 : 2     foo: add_property(z,true)
main.cpp:65 : 2     Closing node [elib::NoClass,foo]
main.cpp:40 : 1 map: add_property(asiz,529)
main.cpp:40 : 1 map: add_property(strval,"this is a string")
main.cpp:65 : 1 Closing node [YetAnotherNoopClass,map]

The amount of lex code is remarkably small, and of course i made a toc sn=
ippet=20
to process them for me :).

So... with this, if we will move the load/save functions out of SerialTre=
e's=20
immediate interface, i can have a format-compatible text-based de/seriali=
zer=20
ready which doesn't need any libs other than libfl. :) i'm using flex's C=
++=20
interface because it allows easy redirection from/to streams, so it's=20
possible to use stringstreams (instead of just C-style FILE *).
