You can get specific versions by looking at the other `julia*` top-level derivations available. For example, `julia_19` corresponds to Julia 1.9. We also provide the current stable version as `julia-stable`, and an LTS version as `julia-lts`. + +Occasionally, a Julia version has been too difficult to build from source in Nixpkgs and has been fetched prebuilt instead. These Julia versions are differentiated with the `*-bin` suffix; for example, `julia-stable-bin`. + +## julia.withPackages {#julia-withpackage} + +The basic Julia derivations only provide the built-in packages that come with the distribution. + +You can build Julia environments with additional packages using the `julia.withPackages` command. This function accepts a list of strings representing Julia package names. For example, you can build a Julia environment with the `Plots` package as follows. + +```nix +julia.withPackages ["Plots"] +``` + +Arguments can be passed using `.override`. For example: + +```nix +(julia.withPackages.override { + precompile = false; # Turn off precompilation +}) ["Plots"] +``` + +Here's a nice way to run a Julia environment with a shell one-liner: + +```sh +nix-shell -p 'julia.withPackages ["Plots"]' --run julia +``` + +### Arguments {#julia-withpackage-arguments} + +* `precompile`: Whether to run `Pkg.precompile()` on the generated environment. + + This will make package imports faster, but may fail in some cases. For example, there is an upstream issue with `Gtk.jl` that prevents precompilation from working in the Nix build sandbox, because the precompiled code tries to access a display. Packages like this will work fine if you build with `precompile=false`, and then precompile as needed once your environment starts. Defaults to `true`. + +* `extraLibs`: Extra library dependencies that will be placed on the `LD_LIBRARY_PATH` for Julia. + + Should not be needed as we try to obtain library dependencies automatically using Julia's artifacts system. + +* `makeWrapperArgs`: Extra arguments to pass to the `makeWrapper` call which we use to wrap the Julia binary. +* `setDefaultDepot`: Whether to automatically prepend `$HOME/.julia` to the `JULIA_DEPOT_PATH`. + + This is useful because Julia expects a writable depot path as the first entry, which the one we build in Nixpkgs is not. If there's no writable depot, then Julia will show a warning and be unable to save command history logs etc. Defaults to `true`. + +* `packageOverrides`: Allows you to override packages by name by passing an alternative source. + + For example, you can use a custom version of the `LanguageServer` package by passing `packageOverrides = { "LanguageServer" = fetchFromGitHub {...}; }`. + +* `augmentedRegistry`: Allows you to change the registry from which Julia packages are drawn. + + This normally points at a special augmented version of the Julia [General packages registry](https://github.com/JuliaRegistries/General). If you want to use a bleeding-edge version to pick up the latest package updates, you can plug in a later revision than the one in Nixpkgs. diff --git a/nixos/doc/manual/release-notes/rl-2405.section.md b/nixos/doc/manual/release-notes/rl-2405.section.md index e44369ea6f98b..ad9d2212e6732 100644 --- a/nixos/doc/manual/release-notes/rl-2405.section.md +++ b/nixos/doc/manual/release-notes/rl-2405.section.md @@ -14,6 +14,8 @@ In addition to numerous new and upgraded packages, this release has the followin - This can be disabled through the `environment.stub-ld.enable` option. - If you use `programs.nix-ld.enable`, no changes are needed.
