We have this nice `runExecline` now, so we don’t need to use `runCommand` (which spawns bash) just to write a simple script.

# Takes a derivation and a list of binary names
|
|
# and returns an attribute set of `name -> path`.
|
|
# The list can also contain renames in the form of
|
|
# `{ use, as }`, which goes `as -> usePath`.
|
|
#
|
|
# It is usually used to construct an attrset `bins`
|
|
# containing all the binaries required in a file,
|
|
# similar to a simple import system.
|
|
#
|
|
# Example:
|
|
#
|
|
# bins = getBins pkgs.hello [ "hello" ]
|
|
# // getBins pkgs.coreutils [ "printf" "ln" "echo" ]
|
|
# // getBins pkgs.execline
|
|
# [ { use = "if"; as = "execlineIf" } ]
|
|
# // getBins pkgs.s6-portable-utils
|
|
# [ { use = "s6-test"; as = "test" }
|
|
# { use = "s6-cat"; as = "cat" }
|
|
# ];
|
|
#
|
|
# provides
|
|
# bins.{hello,printf,ln,echo,execlineIf,test,cat}
