Hi there,
I'm looking the way for call a list of SNIPPETs using an array of
ksmeta variables, but finally cheeta doesn't like it. Something like
this:

What does cheeta say?

cobbler ... --ksmeta="machinetype=kvm machineenv=db"
...

#set $machinetype = $getVar('$machinetype')
#set $machineenv = $getVar('$machineenv')
$SNIPPET('spacewalk/1/$machinetype')
$SNIPPET('spacewalk/1/$machineenv')

You *might* need to evaluate this outside of the $SNIPPET call. THat is,
try:

#set $machinetypesnippet = 'spacewalk/1/$getVar('$machinetype')'
#set $machineenvsnippet = 'spacewalk/1/$getVar('$machineenv')'

$SNIPPET($machinetypesnippet)
$SNIPPET($machineenvsnippet)

Does that make any difference?

Hi,

Nop, it doesn't work neither.
This is the output:

Here is the corresponding Cheetah code.
** I had to guess the line & column numbers, so they are probably
incorrect:

Line 217, column 1

Any idea?
Thanks so much.

Hi there,

I don't want to believe this is impossible!

Sending "... ksmeta=machinetype=machinetypesnippet" and with this code... :

#set machineenvsnippet = "\'" + "spacewalk/1/" + $getVar("$machinetype", 
"") + "\'"
echo "---------------- debug"
echo $machineenvsnippet
echo "---------------- calling snippet with variable"
$SNIPPET($machineenvsnippet)
echo "---------------- calling snippet directly"
$SNIPPET('spacewalk/1/machinetypesnippet')

I obtain this:

echo "---------------- debug"
echo 'spacewalk/1/machinetypesnippet'
echo "---------------- calling snippet with variable"
# Error: no snippet data for 'spacewalk/1/machinetypesnippet'
echo "---------------- calling snippet directly"
echo "This is machinetypesnippet"

What I'm doing wrong?
Thanks so much, again.

Antonio.
