[Opde-devel] Type scripts and binary service

[Filip V. <f.v...@ce...>]

Hi everyone!

I've just commited a non-tested (though it compiles under linux) 
compiler for type definition scripts. There are no examples of syntax 
usage (just the one below), but the BNF should be quite readable.

As you may see,  I do not include the labels for the fields, only 
they're names.

I'll try to finish (and test) this next week.

In the meantime, I'm writing a xml to dtype converter script in perl. It 
nearly works ok (here is a sneek-peek at resulting structure). The 
structure comes from telliameds xml definition files from dark utils.:

bitfield aiawarenessflags {
    key "Seen" 0x01
    key "Heard" 0x02
    key "Can Raycast" 0x04
    key "Line of Sight" 0x08
    key "Blind" 0x10
    key "Deaf" 0x20
    key "Highest" 0x40
    key "First Hand" 0x80
}

enum airating : uint {
    key "Null" 0
    key "Well Below Average" 1
    key "Below Average" 2
    key "Average" 3
    key "Above Average" 4
    key "Well Above Average" 5
}

namespace Properties {

    // Label: AnimLight
    struct AnimLight {
        int32 unk1
        vector offset
        int32 unk2 = "1"
        int16 cellindex
        int16 hitcells
        int16 lightnum = "-1"
        uint16 use animlightmode mode = "4"
        int32 brightentime
        int32 dimtime
        float minbrightness
        float maxbrightness
        int32 unk4
        bool32 rising
        int32 countdown
        bool32 inactive
        float radius
        int32 unk5
    }

}

It will all look like this. The syntax is not very complex. The "use 
animlightmode" is an example of enumeration/bitfield referencing. after 
=, there is a default value.


The labels should be defined in some language packs if needed for 
editor. Note this is only a data  structure definition script language. 
There will be other format - property and link definition scripts. Those 
will reference these structures.

Binary service should work ok, though not tested either.

That's it for now.

I'll welcome any comments.
