Re: [WINTCL] Dict and array

[Tobias G. <ga...@un...>]

Hi Oleksiy, tcl arrays cannot be elements of dicts afaik, but You can
rather try nested dicts.
I'm not quite sure why You want/need the tcl array there. If You just
want hierarchical structure, maybe nested dicts (or nested lists), or
arrays of dicts could solve Your problem.


To use nested dicts, please try changing Your code to the following

% set Var [dict create \
Var1 [dict create SubVar1 {1 {1 2 3 4} 2 {1 2 3 4}}\
] \
]

Var1 {SubVar1 {1 {1 2 3 4} 2 {1 2 3 4}}}
%

which is a nested dict (and can also be treated as nested list).



If for some technical reason you absolutely need the contents of SubVar1
to reside in a tcl array at runtime, You could create an array variable
at runtime and populate it (using array set) with SubVar1


Wile arrays cannot be key or value of a dict, a tcl array of dicts is
possible,
there is an example on http://wiki.tcl.tk/5042 about using dicts as
values of a tcl array:


array set U {
    tom  { Name {Tom Brown}  Sex M  Age 19  Class {4 5} }
    mary { Name {Mary Brown} Sex F  Age 16  Class {5}   }
    sam  { Name {Sam Spade}  Sex M  Age 19  Class {3 4} }
}

dict set     U(tom)  Sex F
dict append  U(sam)  Name { Jr}
dict lappend U(sam)  Class 5
dict incr    U(mary) Age
dict set     U(tom)  Sax Y;  # Creates a new key.
dict set     U(bill) Sax N;  # Creates a new entry.



regards,
Tobi
