replace
The replace filter replaces placeholders in a string (the placeholder
format is free-form):
1 2 3 4 5 6 7
{{ "I like %this% and %that%."|replace({'%this%': fruit, '%that%': "oranges"}) }}
{# if the "fruit" variable is set to "apples", #}
{# it outputs "I like apples and oranges" #}
{# using % as a delimiter is purely conventional and optional #}
{{ "I like this and --that--."|replace({'this': fruit, '--that--': "oranges"}) }}
{# outputs "I like apples and oranges" #}
