QUESTION

Why is `functionArgs` implemented twice? (i.e, as a primop and in `lib`)

Asked 2021-Apr-16 at 14:44

Trying to understand callPackage, so looked up its implementation where it uses lib.functionArgs (source), but there is already a builtins.functionArgs primop, an alias of __functionArgs (implemented in C).

lib.functionArgs is defined as

lib.functionArgs wraps builtins.functionArgs in order to provide reflective access to generic functions.

This supports reflection with builtins.functionArgs:

The thing your write after ? is not an expression: it is an attribute path. This allows you to do powerful things like pkgs ? hello.src which probes to see whether pkgs has an attribute named hello which has an attribute named src.

When Nix evaluates a ? b, Nix just looks at the name "b", it does not consider whether "b" is a variable in the local context. So pkgs ? n is true if an only if pkgs is a set with a member that literally is named "n".

Here is an example repl session that explores the issue. The last line shows a possible solution for what I think you are trying to do.

QUESTION

nix nixlang: undefined variable pkgs in default.nix via nix-build -A hello but works in nix repl

Asked 2020-Feb-09 at 02:10

I wrote a very simple default.nix file with which I should be able to build the gnu hello package (similiar to nix-pills).

But now i've come across an error:

[jane@nixos:~/graphviz]$ nix-build -A hello

error: undefined variable 'pkgs' at /home/jane/graphviz/default.nix:3:47

this is the source code :

The { } syntax only defines a value. It does not bring the attributes in it into scope. You can use the rec { } syntax which does do both.

Values in nix are immutable; you can't change the value of test.a, because that would require changing the set. You can only create a new set with a different a value.
