How does it work confusion

[idontgetoutmuch]

I read the documentation but I don't know why I still need the toml files.

They are referenced by the generated Nix derivation, specifically in common.nix. Is it a problem to include them?

Do I need to write a devShell for newbie users to julia2nix frendly?

[idontgetoutmuch]

I was a bit suspicious that I had done something wrong and that somehow julia was just using the toml and not using nix. Looking at the output below, it still feels like that is what is happening though.

@GTrunSec if you mean me, I am not sure. What would a devShell do?

One of my problems was that julia wasn't building in nix in macos and so I had to patch the derivation and use my local nixpkgs.

[GTrunSec]

first, modify { pkgs ? import <nixpkgs>) { } } to { pkgs ? import (import <your local-nixpkgs path>") { } }: in default.nix

second, make sure you have done to generated packages.nix with julia2nix

third, run $(nix-build . --no-out-link)/bin/julia to enter julia

please, check ENV first, make sure you got DEPOT_PATH as following:

"JULIA_DEPOT_PATH"       => "./.julia_depot:/nix/store/w7rzd4jvhcr60j3fgy9j148vmzbhjs5f-julia-depot"

finally, activate your packages.toml in julia repl:

using Pkg
Pkg.activate(".")
using <your package>

[GTrunSec]

the devShell just help your https://github.com/GTrunSec/my-julia2nix-env/blob/main/shell.nix to use direnv or some commands, envrs easily and simply.

[idontgetoutmuch]

first, modify { pkgs ? import <nixpkgs>) { } } to { pkgs ? import (import <your local-nixpkgs path>") { } }: in default.nix

second, make sure you have done to generated packages.nix with julia2nix

third, run $(nix-build . --no-out-link)/bin/julia to enter julia

I have $(nix-build -I nixpkgs=/Users/dom/nixpkgs . --no-out-link)/bin/julia which should do the same?

[GTrunSec]

to { pkgs ? import (import /Users/dom/nixpkgs") { } }: then run $(nix-build . --no-out-link)/bin/julia

[idontgetoutmuch]

please, check ENV first, make sure you got DEPOT_PATH as following:

"JULIA_DEPOT_PATH"       => "./.julia_depot:/nix/store/w7rzd4jvhcr60j3fgy9j148vmzbhjs5f-julia-depot"

I have "JULIA_DEPOT_PATH" => "/Users/dom/.julia:/nix/store/pcsy2x5wivay4fhzk2gm6qiggq29pds6-julia-depot" so it looks like it is working :-) thanks for your help

[thomasjm]

Cool, glad things are working. Is there anything else needed on this issue? I didn't totally understand the devShell suggestion so not sure if any action items are desired there.

[idontgetoutmuch]

I think we can close this.
