Hi, I have a problem trying to correctly understand the docs
in the section where the ::request::global is explained (Internals).
The question (attempt to preserve functioning tcl scripts
when they are "cut'n'pasted" into rivet pages) is put in a
way that (seems to me) it warns the developer that "global" is meant
for persistence whereas the ::request::global command is for making
into Rivet traditional "global scope" variables.
(I don't see any other possible reason for bringing up the problem
in the documentation). Am I misunderstanding the whole stuff?
I wrote a sample script using ::request::global, global, ::global in turn
trying to have persistence, but obtained only variables that are created
every time I reload the page.
<?
global visits #or ::request::global visits or ::global visits
set visits([clock seconds]) [env REMOTE_ADDR]
foreach {t ip} [array get vists] {
puts "-> $t $ip <br />"
}
?>
My comprehension of the docs is maybe unadequate, but
I suggest to reformulate the paragraph in a more schematic
form.
cheers.
