Preventing comma from being added at last loop occurance.

[StartledPhoenix]

If I have a jinja loop similar to
{% foreach cat, catdesc in pillar['cats'].iteritems() %}
{% if catdesc['catcolor'] is defined %}
{{ cat }} is {{ catdesc['catcolor'] }},
{% else %}
{{ cat }} has no known color
{% endif %}

how can I make it so that the last entry has no comma?

Hello Phoenix,

Maybe the following snippet may help you:

{% set vhosts_list = [] -%}

{% for key in vhosts | sort -%}

{% do vhosts_list.append(key) -%}

{% endfor -%}

vhosts={{vhosts_list|join(',')}}

{% for key in vhosts | sort -%}

[{{key}}]

{% for k in vhosts[key] -%}

{{k}}={{vhosts[key][k]}}

{% endfor -%}

Best,

Valentin

Jinja has builtin support for doing this kind of stuff.
See: http://jinja.pocoo.org/docs/dev/templates/#for
→ loop.first
→ loop.last

You already got some good replies. In case you're looking for a
practical example you'll find one at

Have fun.

Thanks for the help :)

Sad that jinja doesn't have a way of doing this natively, but your code
works well.
