Handle multiline environment variables

[Aegdesil]

I have an issue when parsing multiline environment variables, the cli is not able to parse them.

export TEST_VALUE='first line
next line'

env | jinja2 --format env my_file.txt

This raises a ValueError because the environment variables file is parsed line by line, and the second line does not contain a variable name.

How can I handle such variables ?

~/test: $ cat my_file.txt
Print {{ environ('TEST_VALUE') }}

~/test: $ export TEST_VALUE='first line
next line'

~/test: $ jinja2 my_file.txt
Print first line
next line
