Follow-up Comment #7, bug #22774 (project wesnoth):
I concur with tekelili.
*Reason 1)*
This is how
[insert_tag] name=tag variable=my_var [/insert_tag]
works:
It inserts the array my_var, but renames the array name from 'my_var' to
'tag'…
… with one exception: a non-existent array is processed a different way
And exceptions are bad in general. As tekelili pointed out, one must care
about them in the code.
*Reason 2)*
I believe the effect of insert_tag shall depend uniquely on the tag name and
the content of the variable (more precisely: of the array).
In other words, next sentence should be true:
_Let's have two instances of insert_tag. Their effect is equal if and only if
both 'name=' and the content of 'variable' are equal._
But the sentence is not true with the current insert_tag mechanism. Variables
'nothing' (in A) and 'something' (in B) are different, but insert_tag still
inserts an equal code:
# A)
{CLEAR_VARIABLE nothing}
[insert_tag]
name=redraw
variable=nothing
[/insert_tag]
# B)
[set_variables]
name=something
mode=replace
[literal]
[/literal]
[/set_variables]
[insert_tag]
name=redraw
variable=something
[/insert_tag]
