# This script is used by the Makefile to have an implicit nix-shell.
|
|
# The following environment variables modify the script behavior:
|
|
# - TARGET: This attribute is passed as `targets` arg to Nix, limiting the scope
|
|
# of the Nix expressions.
|
|
# - _NIX_ATTR: Used to specify an attribute set from inside the expression in `default.nix`.
|
|
# This allows for drilling down into a specific attribute in Nix expressions.
|
|
# - _NIX_PURE: This variable allows for making the shell pure with the use of --pure.
|
|
# Take note that this makes Nix tools like `nix-build` unavailable in the shell.
|
|
# - _NIX_KEEP: This variable allows specifying which env vars to keep for Nix pure shell.
