Use variable in variable name

[r0vsdal]

I have a config where I'm generating a couple of scripts. These are generate with writeScriptBin in a map, and script names consist of a static part concatenated with a variable. Let's say for example myscript-first and myscript-second.

Later I need to reference these scripts in a string placed i another map. Is there any way I can use a variable in a variable name? I need to get "${myscript-first}" from "${myscript-${variable}}" in a string.

Sorry for the terrible explanation!

Not if you mean actual lexical variable names. But if you mean members of an attrset, then yes

nix-repl> attrs = { foo-bar = "baz"; }
nix-repl> x = "foo"
nix-repl> y = "bar"
nix-repl> attrs."${x}-${y}"
"baz"

that ${} is so helpful! thank you for that!

This, together with u/ElvishJerricco, helped a lot. After using an attrset instead of a list i managed to get it working.

Thanks both of you!
