[Gnu-arch-users] [TLATOR] Status report

[Samium Gromoff]

Whew. 
Ok, so tlator`s approaching to the state when about everything
lost in prevous two major rewrites is back.

Now i feel that i`ve made a good effort in simplifying adding
features (read tree-based dialogs) into tlator.

And the appearance itself becomes more general: note the
"browse" button on the bar which appears when you click on
browseable objects -- namely revisions, srctrees and
various undos/inventories/changes.

About stuff which makes it possible:

Over time i`ve split the tlator functionality on three parts:

1. libnspace -- a generic namespace/type/method/action/object system

 - namespaces have type tables
 - types have generic methods and specific actions
 - methods may have either no impementation, a generic one or a
        type-specific one
 - every object (NSPACE_TREE_NODE) references a type
 - convenient tree walking (tree_for_each, tree_for_childs,
        tree_for_lead)
 - generic table handling (table_def, table_for_each)

2. libnsui -- a generic namespace visualisation mechanism

 provides facilities for convenient visualisation of namespaces,
 and also a place where the generic convenience stuff hides:

 - one component per namespace viewing session
 - the component action bar (the buttons on the below) is just
        a set of actions defined for the selected object`s type.

3. libnspace -- a realisation of an arch gui using libnsui

 that`s where the dialogs/tla wrappers/logic hide.

features:
 - dding namespaces/types is fairly simple:
        It`s a matter of defining the type, and editing the
        namespace description file, which gets compiled into
        a large .c file which basically fills the tables.
        Also you need to provide methods which you have
        choosed to have type-specific implementation.
 - fairly good effort have been put into function namespace
        cleanlines issue: almost everything is prefixed with
        either nspace_, nsui_ or tlator_.

i may have forgotten something, but otherwise its a fairly
complete tlator architecture overview.
