Using Typst packages

If none of the advice on this page works for you, and there are no open issues related to your problem, feel free to open an issue.

You can find a full working example using Typst packages here.

Typst packages are still experimental, so Typix doesn't provide direct support for them yet. However, there are ways you can get them to work.

Typst packages should work out of the box for:

• watchTypstProject
• devShell

For the other derivation constructors, see below.

Providing the package cache

Typst caches downloaded packages for a given namespace in {cache-dir}/typst/packages/{namespace}.

With flake inputs defined like:

{
  inputs.typst-packages = {
    url = "github:typst/packages";
    flake = false;
  };

  # Contrived example of an additional package repository
  inputs.my-typst-packages = {
    url = "github:loqusion/my-typst-packages";
    flake = false;
  };
}

...we can provide them where Typst expects them:

let
  typstPackagesSrc = pkgs.symlinkJoin {
    name = "typst-packages-src";
    paths = [
      "${inputs.typst-packages}/packages"
      "${inputs.my-typst-packages}/..."
    ];
  };
  # You can use this if you only need to use official packages
  # typstPackagesSrc = "${inputs.typst-packages}/packages";

  typstPackagesCache = pkgs.stdenv.mkDerivation {
    name = "typst-packages-cache";
    src = typstPackagesSrc;
    dontBuild = true;
    installPhase = ''
      mkdir -p "$out/typst/packages"
      cp -LR --reflink=auto --no-preserve=mode -t "$out/typst/packages" "$src"/*
    '';
  };
in {
  build-drv = typixLib.buildTypstProject {
    XDG_CACHE_HOME = typstPackagesCache;
    # ...
  };

  build-script = typixLib.buildTypstProjectLocal {
    XDG_CACHE_HOME = typstPackagesCache;
    # ...
  };
}

Then, we can use them in a Typst file like so:

#import "@preview/example:0.1.0"
#import "@loqusion/my-package:0.2.1"
