Development Shell helpers

The nix-shell command has popularized the concept of transient shell environments for development or testing purposes.

However, nix-shell is not the only way to create such environments, and even nix-shell itself can indirectly benefit from this library.

This library provides a set of functions that help create such environments.

devShellTools.valueToString

Converts Nix values to strings in the way the derivation built-in function does.

Example

## `valueToString` usage examples

devShellTools.valueToString (builtins.toFile "foo" "bar")
=> "/nix/store/...-foo"

devShellTools.valueToString false
=> ""
