Hi Frank,
unfortunatily pd has next to no string functions (without externals).
Otherwise it shouldn't be too hard, to write a hashfunction
that retrieves a numeric hash for a given symbol, which could
be used as struct index.
At least something like get_character_of_symbol_at_position
and get_ascii_value_of_character would be needed to do so.
All the best,
Lsw~

Maybe this is something close:

Yeah, but I was thinking of something faster than walking around in a
textfile
would be. :) The really nice thing about data structure arrays is that
they are
very fast. The not so nice things are that they only accept integers for
lookup
and that the structure of the thing they store has to be predefined.
What I would love would be a "map" type field for [struct] so you could
say:
[struct item float i]
[struct example map items item]
just like for the "array" field. But now the index to lookup a map
element
would be a symbol key.
The setter could look like this:
[symbol key(
|
[mapelement example items]
[100\ |
| |
[set item i]
and a getter like this:
[symbol key(
|
[mapelement example items]
|
[get item i]
|
[100\
All in analogy to [element] for arrays
Ciao
