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

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

The full module may look like:

#%Module
if {[module-info mode load]} {
    switch -- [module-info shelltype] {
        sh {puts stdout "FOO='my\nmulti\nline\nvalue'; export FOO;"}
    }
} elseif {[module-info mode unload]} {
    unsetenv --unset-on-unload FOO
}

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.
