Nix expressions for VS Code Extensions

As of October 2, 2025, the nixpkgs repository contains 456 VS Code extensions. This is a small fraction of the nearly 80,000 extensions available on the VS Code Marketplace. In addition, many of the extensions in nixpkgs are outdated.

This flake provides Nix expressions for the latest pre-release and release versions of the majority of available extensions from the VS Code Marketplace and the Open VSX Registry. A GitHub Action updates these extensions daily.

Important

Don't abuse this flake

We have a permission from MS to use a crawler on their API (see the discussion).

Don't abuse this flake!

nix4vscode

Check nix4vscode (and contribute!) if you need more extension versions.

Prerequisites

Read NixOS wiki

Read the VS Code page on the NixOS wiki.

(Optional) Enable flakes and experimental commands

Read about Nix flakes.
Set them up.
Enable the nix-command option to use nix repl and other experimental commands (see Start REPL, Explore). This option should already be enabled if you followed the setup instructions for flakes.

(Optional) Allow unfree packages

See Unfree extensions.

(Optional) Enter the repository directory

Clone this repository and enter its directory.

git clone https://github.com/nix-community/nix-vscode-extensions
cd nix-vscode-extensions

(Optional) Start REPL

See nix repl.

nix repl

(Optional) Get your system

system="$(nix-instantiate --eval --expr "builtins.currentSystem")"

On my system:

printf "$system"
"x86_64-linux"

Note

You can use the value that you got on your machine instead of builtins.currentSystem in instructions below.

History

You can search for an extension in the repository history:

Get commits containing the extension: git log -S '"copilot"' --oneline data/cache/vscode-marketplace-latest.json
Select a commit, e.g.: 0910d1e
Search in that commit: git grep '"copilot"' 0910d1e -- data/cache/vscode-marketplace-latest.json

Example

The ./nix/vscode-with-extensions.nix provides an example of vscode-with-extensions.

This package is VS Code with a couple of extensions.

Run VS Code and list installed extensions.

List extensions with flakes

nix run github:nix-community/nix-vscode-extensions/fd5c5549692ff4d2dbee1ab7eea19adc2f97baeb#default -- --list-extensions

Template

This repository has a flake template.

This template provides a VSCodium with a couple of extensions.

Create a flake from the template (see nix flake new).

nix flake new vscodium-project -t github:nix-community/nix-vscode-extensions
cd vscodium-project
git init && git add .

Run VSCodium.
```
nix run .# .
```
Alternatively, start a devShell and run VSCodium. A shellHook will print extensions available in the VSCodium.
```
nix develop .#vscodium
codium .
```

In case of problems see Troubleshooting.

Overlay

See Overlays.

If you use NixOS, Home Manager, or similar:

If you use flakes, add nix-vscode-extensions to your flake inputs (see example).

inputs.nix-vscode-extensions.url = "github:nix-community/nix-vscode-extensions/fd5c5549692ff4d2dbee1ab7eea19adc2f97baeb";
outputs = inputs@{ nix-vscode-extensions, ... }: ...

If you don't use flakes, import the nix-vscode-extensions repository.

let
  nix-vscode-extensions = import (
    builtins.fetchGit {
      url = "https://github.com/nix-community/nix-vscode-extensions";
      ref = "refs/heads/master";
      rev = "fd5c5549692ff4d2dbee1ab7eea19adc2f97baeb";
    }
  );
in

Add the nix-vscode-extensions.overlays.default to nixpkgs overlays (see Get extensions via the overlay, example).
(Optional) Allow unfree packages (see Unfree extensions).
Use pkgs.nix-vscode-extensions.vscode-marketplace, pkgs.nix-vscode-extensions.open-vsx and others (see The extensions attrset, Explore, example).

Note

See With-expressions.

In with A; with B;, the attributes of B shadow the attributes of A.

Keep in mind this property of with when writing with vscode-marketplace; with vscode-marketplace-release;.

Extensions

Platforms

We provide attrsets that contain both universal and platform-specific extensions.

We use a reasonable mapping between the sites target platforms and Nix-supported platforms (see systemPlatform in flake.nix, issue).

The `extensions` attrset

Note

Here, * stands for a sequence of zero or more characters.

The Get extensions section explains how to get the extensions attrset.

This attrset contains several attributes described in the sections Extension attrsets and Functions that produce extension attrsets.

Extension attrsets

We have no reliable way to choose the semantically latest cached version of an extension (see cache files).

Therefore, we used the following method:

We chose properties of extension versions that may predict whether a version is the latest one:
- whether a version is pre-release or release;
- whether a version is universal or platform-specific.
We prioritized all combinations of property values.
We created several attrsets of extensions with constraints on possible combinations of property values.
We named attrsets to show additional constraints. E.g., vscode-marketplace* attrsets contain only extensions from the VS Code Marketplace.
In each attrset, for each extension whose versions could be in that attrset, we provided a single highest-priority version of that extension.

The next sections show permitted property combinations and their priorities in corresponding attrsets.

`vscode-marketplace` and `open-vsx`

pre-release platform-specific
pre-release universal
release platform-specific
release universal

`vscode-marketplace-release` and `open-vsx-release`

release platform-specific
release universal

`vscode-marketplace-universal` and `open-vsx-universal`

pre-release universal
release universal

`vscode-marketplace-release-universal` and `open-vsx-release-universal`

release universal

Functions that produce extension attrsets

`forVSCodeVersion`

forVSCodeVersion version produces an attrset similar to extensions (see The extensions attrset) but containing only the extensions compatible with the version version of VS Code (see Versions compatible with a given version of VS Code).

You should replace version with your VS Code or VSCodium version.

`usingFixesFrom`

usingFixesFrom nixpkgsWithFixes produces an attrset where particular extensions have fixes specified in the supplied nixpkgsWithFixes (see mkExtensionNixpkgs in mkExtension.nix, Versions with fixes from particular nixpkgs, Use fixes from nixpkgs).

The supplied nixpkgsWithFixes can be any version of nixpkgs (see Get nixpkgs).
The supplied nixpkgsWithFixes is used only to look up the fixes in its source code and is independent of the nixpkgs that you apply the overlay to.

The top-level vscode-marketplace* and open-vsx* attributes are constructed using fixes from nixpkgs that you apply the overlay to (if you get extensions via the overlay) or nixpkgs from the nix-vscode-extensions repository (if you get extensions from nix-vscode-extensions).

Extension identifiers

Extension publishers and names are lowercased only in Nix.
- They're not lowercased in .json cache files.
Access an extension in the format <attrset>.<publisher>.<name>, where <attrset> is vscode-marketplace, open-vsx, etc. (see Explore).
If an extension publisher or name aren't valid Nix identifiers, quote them like <attrset>."4"."2".

Missing extensions

Some previously available extensions may be unavailable in newer versions of this flake.
- An extension is missing if it doesn't appear during a particular workflow run in a VS Code Marketplace or an Open VSX response about the full set of available extensions (see discussion).
- We let missing extensions remain in cache files and plan to purge missing extensions periodically (see #139).

Extension packs

We don't automatically handle extension packs. You should look up extensions in a pack and explicitly write all necessary extensions.

Unfree extensions

We use derivations and code from nixpkgs for some extensions (see Versions with fixes from particular nixpkgs).
Unfree extensions from nixpkgs stay unfree here (see Unfree software, Special extensions).

If you want to use unfree extensions, try one of the following ways:

Installing unfree packages.
Global configuration - Example.

Set config.allowUnfree = true when constructing pkgs.

pkgs = import nixpkgs {
  system = builtins.currentSystem;
  config.allowUnfree = true;
  overlays = [ overlays.default ];
}

Override the license of a particular extension.

let
  resetLicense =
    drv:
    drv.overrideAttrs (prev: {
      meta = prev.meta // {
        license = [ ];
      };
    });
in
resetLicense <publisher>.<name>

Versions compatible with a given version of VS Code

See forVSCodeVersion.

nix-repl> extensionsCompatible = extensions.forVSCodeVersion "1.78.2"

The extensionsCompatible attrset contains some of the the extensions attrset attributes.

Versions with fixes from particular `nixpkgs`

Some extensions require non-trivial fixes (example).

These fixes may be available in a particular version of nixpkgs.

These fixes are read from the source code of that nixpkgs version (see mkExtensionNixpkgs in mkExtension.nix).

Use fixes from `nixpkgs`

Get extensions.

In this case, we use the same version of nixpkgs that was used to get extensions. You can use any other version instead.

nix-repl> extensionsFixed = extensions.usingFixesFrom nixpkgs

The extensionsFixed attrset contains some of the the extensions attrset attributes.

Removed extensions

Some extensions are unavailable or don't work on particular platforms.

These extensions are disabled via removed.nix.

README

Fix links.
Write new sections.
Update commit hashes used in examples if they're too old.
Enhance the text.

Extra extensions

The extra-extensions.toml file contains a list of extensions to be fetched from sites other than VS Code Marketplace and Open VSX. These extensions replace ones fetched from VS Code Marketplace and Open VSX. Add necessary extensions there, preferrably, for all supported platforms (see Extensions). nvfetcher will fetch the latest release versions of these extensions and write configs to generated.nix.

Special extensions

Certain extensions require special treatment.

Provide functions to build such extension in the extensions directory (see extensions/default.nix).

Optionally, create and link issues explaining chosen functions.

Each extension, including Extra extensions, is built via one of the functions in mkExtension.nix.

These functions don't modify the license of (unfree) extensions from nixpkgs.

Build problems

Extension with multiple extensions in a zipfile (issue)
Platform-specific extensions (comment)

Haskell script

See the ./haskell/README.md.

Troubleshooting

If Nix-provided VSCodium doesn't pick up the extensions:
- Close other instances of Nix-provided VSCodium and start VSCodium again.
- Try to reboot your computer and start VSCodium again.
