env() or getShellEnvVar()

ebecheto

Hi all,

by curiosity i typed env("HOME") instead of getShellEnvVar("HOME"), because it is shorter to write and might help readability of my code.

Although, i cannot find any help on the env() function, so i am wondering if this function is valid and if it is safe to use it.

Anyone knows something about env function ?

Regards,

  • I checked in our SKILL registration database and it's marked as public but with an "override" to not document it. I think that's because it's for legacy. There are some downside:

    1. It's an nlambda function which means you can't use it in SKILL++ mode (this suggests that it's very old)
    2. Because it's an nlambda function, you can't pass a variable containing the env var name to the function - it only takes a literal string or symbol as the first argument.

    So I think it's a conscious decision not to document it to discourage usage.
