merge strings in template

[Jakub Veverka]

Hi,

I am not very familiar with golang template so this might be real easy to answer :)

I have following etcd structure:

/app/customer1/dev
/app/customer1/test
/app/customer2/dev
/app/customer2/test

I would like to read values for all customers, so I am looking for the way to loop through these in confd template.
I've started with following:

{{ $path := "/app/" }}
{{ range ls $path }}
{{$customer := .}}
customer: {{join $path, $customer}}
{{end}}

My problem is that join is not working for me, I have version 0.7.1, not sure if its merged in this version already.

Is there simpler way to iterate through such structure?

Thanks,
Jakub

Ok, this was more golang template question, but I will post my solution here anyway.

Strings can be easily merged in template using printf function:

{{ $customer := printf "%s/%s" "string1" "string2" }}
