RE: [TCLCORE] TIP #224: Add New [array] Subcommands 'incr' and 'v alue'

[WANGNICK S. <seb...@eu...>]

Dear all,

IMHO array value is not necessary.

array value var elem value true
can be written as
array incr var elem 0 value
(provided some logic in the implementation of array incr skips the attempt to add 0 to the value, which might not be numeric)

array value var elem "" false
can be written as
array get var elem

To introduce additional syntax for the strange case where one wants something peculiar to be returned, but not stored in the array, when the element doesn't exist is IMHO not justified.

Regards,
Sebastian

Hi,

nice TIP!

But the terms "value" and "init" are being used for different purposes in
the two subcommands, which I think is calling for confusion. Even more so
since the semantic of the "value" argument to [array value] is similar to
the "init" argument of [array incr].

I think the "value" argument to [array incr] should be called "increment" to
match the documentation of the [incr] command. Then the current "init"
argument could be renamed to "value" or "initvalue". Furthermore,
"initialize" might be a better name for an argument that expects a boolean
value.

  array incr /var elem/ ?/increment/ ?/initvalue/??
  array value /var elem/ ?/value/ ?/initialize/??
