Hi Vladimir,
Thanks . It helps to learn a lot.
Any useful like to learn jijna2 in details will be helpful .
in Btw, why the "cols" are printed as like below , instead of you have
mentioned? is there ansible/jinja version conflict or I miss a bit?
- name: playbook to print the list as table
hosts: localhost
vars:
color:
- green
- red
- yellow
- blue
cities:
- toronto
- montreal
- mumbai
- dubai
lang:
- English
- French
- Hindi
- Arabic
fnames: [color, cities, lang]
cols: |
{% filter from_yaml %}
{% for i in fnames %}
- {{ lookup('vars', i ) }}
{% endfor %}
{% endfilter %}
max: "{{ cols|map('map', 'length')|map('max') }}"
frmt: |
{% filter from_yaml %}
{% for i in max %}
- '%-{{ i }}s '
{% endfor %}
{% endfilter %}
tasks:
- name: print the cols
debug:
msg: "{{cols}}"
- name: print the max
debug:
msg: "{{max}}"
- name: print the frmt
debug:
msg: "{{frmt}}"
- set_fact:
rows: "{{ rows|d(cols.0)|zip(item)|map('flatten') }}"
loop: "{{ cols[1:] }}"
- name: print the frmt
debug:
msg: "{{rows}}"
