Hi Mikael,
Using with_together as follows works for the example you've shown above:
- hosts: localhost
gather_facts: no
vars:
dictname:
mykey1:
myvalue: foo
mykey2:
myvalue: bar
mykey3:
myvalue: blerg
tasks:
- name: Check if line exists
shell: grep {{ item.value.myvalue }} /tmp/test_foo | wc -l
with_dict: dictname
register: check
- name: Mytask
shell: echo "the value for this is {{dictname[item.0].myvalue}}"
when: item.1.stdout != "1"
with_together:
- dictname
- check.results
The odd part is having to use the "item.0" as the key to the dictionary,
which make sense when you consider that with_together iterates over the
objects together, so for a dictionary the result of that iteration would be
the keys rather than the values.
Setting up a test file with simply "blerg" in it, I get the following
output when running the above playbook:
# echo blerg > /tmp/test_foo
# ansible-playbook -vv test_mikael_ml.yml
PLAY [localhost]

I truncated the output there at the end to save some space, the main point
was to show it skipping the "blerg" item in that task.
