Template problem with bash array length syntax

[Dmitry Horbach]

Hi,

Having simple template file with bash valid content like:

${#ArrayName[@]}

will break template module:

- template: src=template dest=template2

TASK: [template src=template dest=template2] ********************************** 

fatal: [127.0.0.1] => {'msg': 'Missing end of comment tag', 'failed': True}

fatal: [127.0.0.1] => {'msg': 'Missing end of comment tag', 'failed': True}

Is there any workaround for this?

{#  #} is a jinja comment tag which is why it is gettitng confused here

try:

{{ '${#ArrayName[@]}' }}

Works great! Thanks a lot Brian.

You can also wrap an entire block text/code in {% raw %}  {% endraw %}:

{% raw %}

for (( 1=0; i<$#allowed_list[@]}; i++ )); do

    allowed=${allowed_list[$i]

    # do something here with $allowed

done

{% endraw %}

This allows you to avoid escaping all the dollar signs, as well...

It gets even more interesting if you get something like this:

define('AUTH_KEY',         'TccKCkdkq.}]I]I?$(.R@L)ASUysg% AB(a5j+`A8_ra6Vu7D*h2Q]||}.{#b}5Xq');

Because the ; makes the engine throw this error:

expected token 'end of print statement', got ';'

Hit something similar when pushing go templates out with the ansible
template command.

Use

{%raw%}
..... line noise goes here ....
{%endraw%}
