[gtp] Re: Yet another GTP extension

[William M. Shubert]

Hmm, now that you talk about it, I think we need to look at this more
carefully. We need a way to set/get the time system used, and to set/get
the current time left for a given player. So maybe:
    set_clock_type <time system> <parameters>
    set_clock <color> <time left in this period> <parameters>
    get_clock_type
    get_clock <color>
Here "get_clock" returns exactly the same as "set_clock_type", and the
format of "get_clock" returns exactly the same as "set_clock". Then we
can specify:

absolute:
*et_clock_type parameters: <time per player>
*et_clock parameters: <time left for this player>

canadian:
*et_clock_type parameters: <main time> <byoyomi time> <byoyomi stones>
*et_clock parameters: <time left in this period> <stones left in this
period or 0 if we are in main time still>

japanese:
*et_clock_type_parameters: <main time> <byoyomi time> <# of byoyomi
periods>
*et_clock parameters: <time left in this period> <byo-yomi period, or 0
if we are still in main time>

etc...how's that?

    usually computer go tournaments are non byo yomi tournaments.
    However, it is useful to have byo yomi in gtp to interface
    programs with IGS or NNGS, and with graphical front ends..
    I agree that we should let room for any time system to be
    supported.
    In the get_clock command, how do we know if we are in byo
    yomi or in the main time, and how do we know there is no 
    byo yomi ?
