Hi Todd Lewis,
Thanks . I am able to understand it . However the split happens based on
',' , and then we remove the quotes with map('map', 'trim')) and align the
lines with range.
However assuming split with delimiter as comma, when i try to replace 1
with 0 the output is [msg: "{{ range(my_var | length) | map('extract',
(my_var | map('split', ',') | map('map', 'trim')), [1]) }}"]
ok: [localhost] =>
msg:
- line1 has
- line2 has
- line3 has
and when tried to add [0 1] in the end [msg: "{{ range(my_var | length) |
map('extract', (my_var | map('split', ',') | map('map', 'trim')), [0 1])
}}"]
it printsok: [localhost] =>
msg:
- i
- i
- i
that is second character in the word line[0]. Is not the split breaks the
words with (',')?
How to print all the available column? instead of 1( yes the full file
without a comma now )
Actually I am trying to print like below
line1 has color-red
line2 has color-blue
line3 has, color-orange
