Hello,
iirc, the overview says something about this not-real-array emulation.
The size suffix (::size) is actually a module parameter, it is not
something embedded.
So, everything here is more a conceptual approach, could have been very
easy something different instead of [ ] to build keys based on an
incremented value.
Again, what so ever you have as 'xyz[n]' is just seen as a string by
htable module, it is effectively the key in the hash table, you can add,
remove, get, etc..
Cheers,
Daniel

Hello Daniel,
The readme file or the cookboks don't say anything about this.
Can you please enhance the readme?
- the indexing: key_name[n]
- the array size: key_name::size
Question: can the following syntax be used to delete a specific
element in an array key?
kamcmd htable.get students anna[2]
kamcmd htable.get students anna[0]
Regards,
Ovidiu Sas

for clarifications, this is still a single key item in memory, just its
format is made 'key_name[n]'. Hash tables by definition work with unique key
indexing.
So adding such items in the hash table should be like:
kamctl mi sht_add ht0 'abc[0]' v0
kamctl mi sht_add ht0 'abc[1]' v1
kamctl mi sht_add ht0 'abc::size' 2

I moved the discussion here, in a separate
thread.
It seems that what are you looking for is not there ... not
implemented.
yes, that is way is asked about it.
If you have the same key_name with different
values in the table, the
last value will be the one loaded in memory.
You can't have an array of values for the same keys.
Also, there's no syntax to access a
particular value in an array.
Maybe that's why there's no option to provide the value.
see this:
o key type - the type of the key
0 - simple key - the key is added as 'key_name'.
1 - array key - the key is added as 'key_name[n]'. n is incremented
for each key with this name to build an array in hash table. for example:
$var(size) = $sht(htable=>$var(key)::size);
$var(i) = 0;
while ($var(i) < $var(size)) {
$var(value) = $sht(htable=>$var(key)[$var(i)]);
...
