help with array in a template.

[digrouz]

Hello guys,

I would like to get some help with puppet about using an array in a
template.

I've a custom facts that return me this:

tsm_vmp / /home /tmp /var/tmp /usr /var

I have a class that use this facts to split it on every space and to a
an entry in a template for each value, here is the code I use for
this:

$virtualmountpoints = split($tsm_vmp, ' ')
...
"/opt/tivoli/tsm/client/ba/bin/dsm.sys":
owner => root,
group => root,
mode => 0600,
content => template("tsm/dsm.sys.erb"),

That's what's I have in my template

<% virtualmountpoints.each do |fs| -%>
virtualmountpoint <%= fs %>
<% end -%>



Thats what I get:
virtualmountpoint /
/home
/tmp
/var/tmp
/usr
/var

but I would like to get instead:
virtualmountpoint /
virtualmountpoint /home
virtualmountpoint /tmp
virtualmountpoint /var/tmp
virtualmountpoint /usr
virtualmountpoint /var


Do you know how to do this?

Very close:

<% virtualmountpoints.each do |fs| -%>

[<%= fs %>]

virtualmountpoint<%= fs %>
<% end -%>

I don't understand the Ruby in that, I copied it from someone else ;-)

I just found my problem,

It is in the split in fact I don't have space between the value but
carried returns, so if I split to "\n", it works.

Hi,

It is in the split in fact I don't have space between the value but
carried returns, so if I split to "\n", it works.

This is slightly worrisome.  I encourage you to go with separating values with a comma, not only because it follows style of how other facts return values, but also ensures that things will not break by accident (something may happen now and/or in the future).  As far as having single space there to separate results is also acceptable, then having "\n" there might not be what you want.  I do encourage you to strip surplus new lines and join values on single comma :)

My 2p, I hope you don't mind :)
