Template fliter and function together usage

[itshikanov]

Hello. I.m try convert my confd config to remco.

try to use filter and function together from here https://github.com/HeavyHorst/remco/tree/26a321844506ca53d2840f22e41ed6ea89043cba/docs/content/template

here the code

{% for member in gets("/members/*") %}
{% set data = member.Value | parseJSON %}
{% set conn_url = data.conn_url | split:"/" | index:"2"  %}
        server {{member.Key | base}} {{ replace (conn_url, "@", "/", -1) | base}}  maxconn 300 check port {{ data.api_url | split:"/" | index:"2" | split:":" | index:"1" }}
{% endfor %}

and here another try

{% for member in gets("/members/*") %}
{% set data = member.Value | parseJSON %}
        server {{member.Key | base}} {{ replace (data.conn_url | split:"/" | index:"2", "@", "/", -1) | base}}  maxconn 300 check port {{ data.api_url | split:"/" | index:"2" | split:":" | index:"1" }}
{% endfor %}

Got the error with replace function

{% for member in gets("/members/*") %}
{% set data = member.Value | parseJSON %}
{{ data.conn_url | split:"/" | index:"2" | replace:"@,/"  }}
{% endfor %}

got error

That work

{{ data.conn_url | toJSON | replace:"@,/" }}

I think because "data.conn_url | toJSON" become String. But if use another pipe, the type of data is changing. If there was toSRING filter at least, it will work
