# Nim {#nim}
## Overview {#nim-overview}
The Nim compiler, a builder function, and some packaged libraries are available
in Nixpkgs. Until now each compiler release has been effectively backwards
compatible so only the latest version is available.
## Nim program packages in Nixpkgs {#nim-program-packages-in-nixpkgs}
Nim programs can be built using `nimPackages.buildNimPackage`. In the
case of packages not containing exported library code the attribute
`nimBinOnly` should be set to `true`.
The Nim compiler and a builder function is available.
Nim programs are built using `buildNimPackage` and a lockfile containing Nim dependencies.
The following example shows a Nim program that depends only on Nim libraries:
```nix
{ lib, nimPackages, fetchFromGitHub }:
{ lib, buildNimPackage, fetchFromGitHub }:
nimPackages.buildNimPackage (finalAttrs: {
buildNimPackage { } (finalAttrs: {
pname = "ttop";
version = "1.0.1";
nimBinOnly = true;
version = "1.2.7";
src = fetchFromGitHub {
owner = "inv2004";
repo = "ttop";
rev = "v${finalAttrs.version}";
hash = "sha256-x4Uczksh6p3XX/IMrOFtBxIleVHdAPX9e8n32VAUTC4=";
hash = "sha256-oPdaUqh6eN1X5kAYVvevOndkB/xnQng9QVLX9bu5P5E=";
};
buildInputs = with nimPackages; [ asciigraph illwill parsetoml zippy ];
lockFile = ./lock.json;
})
```
## Nim library packages in Nixpkgs {#nim-library-packages-in-nixpkgs}
Nim libraries can also be built using `nimPackages.buildNimPackage`, but
often the product of a fetcher is sufficient to satisfy a dependency.
The `fetchgit`, `fetchFromGitHub`, and `fetchNimble` functions yield an
output that can be discovered during the `configurePhase` of `buildNimPackage`.
Nim library packages are listed in
[pkgs/top-level/nim-packages.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/nim-packages.nix) and implemented at
[pkgs/development/nim-packages](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/nim-packages).
The following example shows a Nim library that propagates a dependency on a
non-Nim package:
```nix
{ lib, buildNimPackage, fetchNimble, SDL2 }:
buildNimPackage (finalAttrs: {
pname = "sdl2";
version = "2.0.4";
src = fetchNimble {
inherit (finalAttrs) pname version;
hash = "sha256-Vtcj8goI4zZPQs2TbFoBFlcR5UqDtOldaXSH/+/xULk=";
};
propagatedBuildInputs = [ SDL2 ];
nimFlags = [
"-d:NimblePkgVersion=${finalAttrs.version}"
];
})
```
## `buildNimPackage` parameters {#buildnimpackage-parameters}
All parameters from `stdenv.mkDerivation` function are still supported. The
following are specific to `buildNimPackage`:
The `buildNimPackage` function takes an attrset of parameters that are passed on to `stdenv.mkDerivation`.
* `nimBinOnly ? false`: If `true` then build only the programs listed in
the Nimble file in the packages sources.
The following parameters are specific to `buildNimPackage`:
* `lockFile`: JSON formatted lockfile.
* `nimbleFile`: Specify the Nimble file location of the package being built
rather than discover the file at build-time.
* `nimRelease ? true`: Build the package in *release* mode.
@ -77,6 +41,72 @@ following are specific to `buildNimPackage`:
Use this to specify defines with arguments in the form of `-d:${name}=${value}`.
* `nimDoc` ? false`: Build and install HTML documentation.
* `buildInputs` ? []: The packages listed here will be searched for `*.nimble`
files which are used to populate the Nim library path. Otherwise the standard
behavior is in effect.
## Lockfiles {#nim-lockfiles}
Nim lockfiles are created with the `nim_lk` utility.
Run `nim_lk` with the source directory as an argument and it will print a lockfile to stdout.
```sh
$ cd nixpkgs
$ nix build -f . ttop.src
$ nix run -f . nim_lk ./result | jq --sort-keys > pkgs/by-name/tt/ttop/lock.json
```
## Lockfile dependency overrides {#nimoverrides}
The `buildNimPackage` function matches the libraries specified by `lockFile` to attrset of override functions that are then applied to the package derivation.
The default overrides are maintained as the top-level `nimOverrides` attrset at `pkgs/top-level/nim-overrides.nix`.
For example, to propagate a dependency on SDL2 for lockfiles that select the Nim `sdl2` library, an overlay is added to the set in the `nim-overrides.nix` file:
```nix
{ lib
/* … */
, SDL2
/* … */
}:
{
/* … */
sdl2 =
lockAttrs:
finalAttrs:
{ buildInputs ? [ ], ... }:
{
buildInputs = buildInputs ++ [ SDL2 ];
};
/* … */
}
```
The annotations in the `nim-overrides.nix` set are functions that take three arguments and return a new attrset to be overlayed on the package being built.
- lockAttrs: the attrset for this library from within a lockfile. This can be used to implement library version constraints, such as marking libraries as broken or insecure.
- finalAttrs: the final attrset passed by `buildNimPackage` to `stdenv.mkDerivation`.
- prevAttrs: the attrset produced by initial arguments to `buildNimPackage` and any preceding lockfile overlays.
### Overriding an Nim library override {#nimoverrides-overrides}
The `nimOverrides` attrset makes it possible to modify overrides in a few different ways.
Override a package internal to its definition:
```nix
{ lib, buildNimPackage, nimOverrides, libressl }:
let
buildNimPackage' = buildNimPackage.override {
nimOverrides = nimOverrides.override { openssl = libressl; };
};
in buildNimPackage' (finalAttrs: {
pname = "foo";
# …
})
```
Override a package externally:
```nix
{ pkgs }: {
foo = pkgs.foo.override {
buildNimPackage = pkgs.buildNimPackage.override {
nimOverrides = pkgs.nimOverrides.override { openssl = libressl; };
};
};
}
```
