-
## Overview {#nim-overview}
4
-
5
-
The Nim compiler, a builder function, and some packaged libraries are available
6
-
in Nixpkgs. Until now each compiler release has been effectively backwards
7
-
compatible so only the latest version is available.
8
-
9
-
## Nim program packages in Nixpkgs {#nim-program-packages-in-nixpkgs}
10
-
11
-
Nim programs can be built using `nimPackages.buildNimPackage`. In the
12
-
case of packages not containing exported library code the attribute
13
-
`nimBinOnly` should be set to `true`.
14
15
The following example shows a Nim program that depends only on Nim libraries:
16
-
17
```nix
18
-
{ lib, nimPackages, fetchFromGitHub }:
19
20
-
nimPackages.buildNimPackage (finalAttrs: {
21
pname = "ttop";
22
-
version = "1.0.1";
23
-
nimBinOnly = true;
24
25
src = fetchFromGitHub {
26
owner = "inv2004";
27
repo = "ttop";
28
rev = "v${finalAttrs.version}";
29
-
hash = "sha256-x4Uczksh6p3XX/IMrOFtBxIleVHdAPX9e8n32VAUTC4=";
30
};
31
32
-
buildInputs = with nimPackages; [ asciigraph illwill parsetoml zippy ];
33
-
34
-
})
35
-
```
36
-
37
-
## Nim library packages in Nixpkgs {#nim-library-packages-in-nixpkgs}
38
-
39
-
40
-
Nim libraries can also be built using `nimPackages.buildNimPackage`, but
41
-
often the product of a fetcher is sufficient to satisfy a dependency.
42
-
The `fetchgit`, `fetchFromGitHub`, and `fetchNimble` functions yield an
43
-
output that can be discovered during the `configurePhase` of `buildNimPackage`.
44
45
-
Nim library packages are listed in
46
-
[pkgs/top-level/nim-packages.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/nim-packages.nix) and implemented at
47
-
[pkgs/development/nim-packages](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/nim-packages).
48
-
49
-
The following example shows a Nim library that propagates a dependency on a
50
-
non-Nim package:
51
-
```nix
52
-
{ lib, buildNimPackage, fetchNimble, SDL2 }:
53
-
54
-
buildNimPackage (finalAttrs: {
55
-
pname = "sdl2";
56
-
version = "2.0.4";
57
-
src = fetchNimble {
58
-
inherit (finalAttrs) pname version;
59
-
hash = "sha256-Vtcj8goI4zZPQs2TbFoBFlcR5UqDtOldaXSH/+/xULk=";
60
-
};
61
-
propagatedBuildInputs = [ SDL2 ];
62
})
63
```
64
65
## `buildNimPackage` parameters {#buildnimpackage-parameters}
66
67
-
All parameters from `stdenv.mkDerivation` function are still supported. The
68
-
following are specific to `buildNimPackage`:
69
70
-
* `nimBinOnly ? false`: If `true` then build only the programs listed in
71
-
the Nimble file in the packages sources.
72
* `nimbleFile`: Specify the Nimble file location of the package being built
73
rather than discover the file at build-time.
74
* `nimRelease ? true`: Build the package in *release* mode.
···
77
Use this to specify defines with arguments in the form of `-d:${name}=${value}`.
78
* `nimDoc` ? false`: Build and install HTML documentation.
79
80
-
* `buildInputs` ? []: The packages listed here will be searched for `*.nimble`
81
-
files which are used to populate the Nim library path. Otherwise the standard
82
-
behavior is in effect.

# Nim {#nim}
2
3
+
The Nim compiler and a builder function is available.
4
+
Nim programs are built using `buildNimPackage` and a lockfile containing Nim dependencies.
5
6
The following example shows a Nim program that depends only on Nim libraries:
7
```nix
8
+
{ lib, buildNimPackage, fetchFromGitHub }:
9
10
+
buildNimPackage { } (finalAttrs: {
11
pname = "ttop";
12
+
version = "1.2.7";
13
14
src = fetchFromGitHub {
15
owner = "inv2004";
16
repo = "ttop";
17
rev = "v${finalAttrs.version}";
18
+
hash = "sha256-oPdaUqh6eN1X5kAYVvevOndkB/xnQng9QVLX9bu5P5E=";
19
};
20
21
+
lockFile = ./lock.json;
22
23
+
nimFlags = [
24
+
"-d:NimblePkgVersion=${finalAttrs.version}"
25
+
];
26
})
27
```
28
29
## `buildNimPackage` parameters {#buildnimpackage-parameters}
30
31
+
The `buildNimPackage` function takes an attrset of parameters that are passed on to `stdenv.mkDerivation`.
32
+
33
+
The following parameters are specific to `buildNimPackage`:
34
35
+
* `lockFile`: JSON formatted lockfile.
36
* `nimbleFile`: Specify the Nimble file location of the package being built
37
rather than discover the file at build-time.
38
* `nimRelease ? true`: Build the package in *release* mode.
···
41
Use this to specify defines with arguments in the form of `-d:${name}=${value}`.
42
* `nimDoc` ? false`: Build and install HTML documentation.
43
44
+
## Lockfiles {#nim-lockfiles}
45
+
Nim lockfiles are created with the `nim_lk` utility.
46
+
Run `nim_lk` with the source directory as an argument and it will print a lockfile to stdout.
47
+
```sh
48
+
$ cd nixpkgs
49
+
$ nix build -f . ttop.src
50
+
$ nix run -f . nim_lk ./result | jq --sort-keys > pkgs/by-name/tt/ttop/lock.json
51
+
```
52
+
53
+
## Lockfile dependency overrides {#nimoverrides}
54
+
55
+
The `buildNimPackage` function matches the libraries specified by `lockFile` to attrset of override functions that are then applied to the package derivation.
56
+
The default overrides are maintained as the top-level `nimOverrides` attrset at `pkgs/top-level/nim-overrides.nix`.
57
+
58
+
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:
59
+
```nix
60
+
{ lib
61
+
/* … */
62
+
, SDL2
63
+
/* … */
64
+
}:
65
+
66
+
{
67
+
/* … */
68
+
sdl2 =
69
+
lockAttrs:
70
+
finalAttrs:
71
+
{ buildInputs ? [ ], ... }:
72
+
{
73
+
buildInputs = buildInputs ++ [ SDL2 ];
74
+
};
75
+
/* … */
76
+
}
77
+
```
78
+
79
+
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.
80
+
- 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.
81
+
- finalAttrs: the final attrset passed by `buildNimPackage` to `stdenv.mkDerivation`.
82
+
- prevAttrs: the attrset produced by initial arguments to `buildNimPackage` and any preceding lockfile overlays.
83
+
84
+
### Overriding an Nim library override {#nimoverrides-overrides}
85
+
86
+
The `nimOverrides` attrset makes it possible to modify overrides in a few different ways.
87
+
88
+
Override a package internal to its definition:
89
+
```nix
90
+
{ lib, buildNimPackage, nimOverrides, libressl }:
91
+
92
+
let
93
+
buildNimPackage' = buildNimPackage.override {
94
+
nimOverrides = nimOverrides.override { openssl = libressl; };
95
+
};
96
+
in buildNimPackage' (finalAttrs: {
97
+
pname = "foo";
98
+
# …
99
+
})
100
+
101
+
```
102
+
103
+
Override a package externally:
104
+
```nix
105
+
{ pkgs }: {
106
+
foo = pkgs.foo.override {
107
+
buildNimPackage = pkgs.buildNimPackage.override {
108
+
nimOverrides = pkgs.nimOverrides.override { openssl = libressl; };
109
+
};
110
+
};
111
+
}
112
+
```
