Re: [Modules] How to set-env with multi line content

[Xavier D. <xav...@gm...>]

Hello Byron,

Setting a multi-line value to an environment variable with "setenv" is
not possible with current version of Modules. I will look at
implementing such feature.

As a workaround, you may use the "puts" command to craft the shell
command to define variable with such specific value:

#%Module
puts stdout "export FOO='my\nmulti\nline\nvalue';"

Regards,
Xavier

This shows me that the module load must outputting a string to bash that is only setting the first line of the file to the variable FOO, then the subsequent file lines are getting dropped right to bash to evaluate.
