Idris packages
|
||||
==============
|
||||
|
||||
This directory contains build rules for idris packages. In addition,
|
||||
it contains several functions to build and compose those packages.
|
||||
Everything is exposed to the user via the `idrisPackages` attribute.
|
||||
|
||||
callPackage
|
||||
------------
|
||||
|
||||
This is like the normal nixpkgs callPackage function, specialized to
|
||||
idris packages.
|
||||
|
||||
builtins
|
||||
---------
|
||||
|
||||
This is a list of all of the libraries that come packaged with Idris
|
||||
itself.
|
||||
|
||||
build-idris-package
|
||||
--------------------
|
||||
|
||||
A function to build an idris package. Its sole argument is a set like
|
||||
you might pass to `stdenv.mkDerivation`, except `build-idris-package`
|
||||
sets several attributes for you. See `build-idris-package.nix` for
|
||||
details.
|
||||
|
||||
build-builtin-package
|
||||
----------------------
|
||||
|
||||
A version of `build-idris-package` specialized to builtin libraries.
|
||||
Mostly for internal use.
|
||||
|
||||
with-packages
|
||||
-------------
|
||||
|
||||
Bundle idris together with a list of packages. Because idris currently
|
||||
only supports a single directory in its library path, you must include
|
||||
all desired libraries here, including `prelude` and `base`.

Node.js packages
|
||||
================
|
||||
The `pkgs/development/node-packages` folder contains a generated collection of
|
||||
[NPM packages](https://npmjs.com/) that can be installed with the Nix package
|
||||
manager.
|
||||
|
||||
As a rule of thumb, the package set should only provide *end user* software
|
||||
packages, such as command-line utilities. Libraries should only be added to the
|
||||
package set if there is a non-NPM package that requires it.
|
||||
|
||||
When it is desired to use NPM libraries in a development project, use the
|
||||
`node2nix` generator directly on the `package.json` configuration file of the
|
||||
project.
|
||||
|
||||
The package set also provides support for multiple Node.js versions. The policy
|
||||
is that a new package should be added to the collection for the latest stable LTS
|
||||
release (which is currently 6.x), unless there is an explicit reason to support
|
||||
a different release.
|
||||
|
||||
If your package uses native addons, you need to examine what kind of native
|
||||
build system it uses. Here are some examples:
|
||||
|
||||
* `node-gyp`
|
||||
* `node-gyp-builder`
|
||||
* `node-pre-gyp`
|
||||
|
||||
After you have identified the correct system, you need to override your package
|
||||
expression while adding in build system as a build input. For example, `dat`
|
||||
requires `node-gyp-build`, so we override its expression in `default-v6.nix`:
|
||||
|
||||
```nix
|
||||
dat = nodePackages.dat.override (oldAttrs: {
|
||||
buildInputs = oldAttrs.buildInputs ++ [ nodePackages.node-gyp-build ];
|
||||
});
|
||||
```
|
||||
|
||||
To add a package from NPM to nixpkgs:
|
||||
|
||||
1. Modify `pkgs/development/node-packages/node-packages-v6.json` to add, update
|
||||
or remove package entries. (Or `pkgs/development/node-packages/node-packages-v4.json`
|
||||
for packages depending on Node.js 4.x)
|
||||
2. Run the script: `(cd pkgs/development/node-packages && ./generate.sh)`.
|
||||
3. Build your new package to test your changes:
|
||||
`cd /path/to/nixpkgs && nix-build -A nodePackages.<new-or-updated-package>`.
|
||||
To build against a specific Node.js version (e.g. 4.x):
|
||||
`nix-build -A nodePackages_4_x.<new-or-updated-package>`
|
||||
4. Add and commit all modified and generated files.
|
||||
|
||||
For more information about the generation process, consult the
|
||||
[README.md](https://github.com/svanderburg/node2nix) file of the `node2nix`
|
||||
tool.

R packages
|
||||
==========
|
||||
|
||||
## Installation
|
||||
|
||||
Define an environment for R that contains all the libraries that you'd like to
|
||||
use by adding the following snippet to your $HOME/.config/nixpkgs/config.nix file:
|
||||
|
||||
```nix
|
||||
{
|
||||
packageOverrides = super: let self = super.pkgs; in
|
||||
{
|
||||
|
||||
rEnv = super.rWrapper.override {
|
||||
packages = with self.rPackages; [
|
||||
devtools
|
||||
ggplot2
|
||||
reshape2
|
||||
yaml
|
||||
optparse
|
||||
];
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
Then you can use `nix-env -f "<nixpkgs>" -iA rEnv` to install it into your user
|
||||
profile. The set of available libraries can be discovered by running the
|
||||
command `nix-env -f "<nixpkgs>" -qaP -A rPackages`. The first column from that
|
||||
output is the name that has to be passed to rWrapper in the code snipped above.
|
||||
|
||||
However, if you'd like to add a file to your project source to make the
|
||||
environment available for other contributors, you can create a `default.nix`
|
||||
file like so:
|
||||
```nix
|
||||
let
|
||||
pkgs = import <nixpkgs> {};
|
||||
stdenv = pkgs.stdenv;
|
||||
in with pkgs; {
|
||||
myProject = stdenv.mkDerivation {
|
||||
name = "myProject";
|
||||
version = "1";
|
||||
src = if pkgs.lib.inNixShell then null else nix;
|
||||
|
||||
buildInputs = with rPackages; [
|
||||
R
|
||||
ggplot2
|
||||
knitr
|
||||
];
|
||||
};
|
||||
}
|
||||
```
|
||||
and then run `nix-shell .` to be dropped into a shell with those packages
|
||||
available.
|
||||
|
||||
## RStudio
|
||||
|
||||
RStudio uses a standard set of packages and ignores any custom R
|
||||
environments or installed packages you may have. To create a custom
|
||||
environment, see `rstudioWrapper`, which functions similarly to
|
||||
`rWrapper`:
|
||||
|
||||
```nix
|
||||
{
|
||||
packageOverrides = super: let self = super.pkgs; in
|
||||
{
|
||||

||||
packages = with self.rPackages; [

|

];
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
Then like above, `nix-env -f "<nixpkgs>" -iA rstudioEnv` will install
|
||||
this into your user profile.
|
||||
|
||||
Alternatively, you can create a self-contained `shell.nix` without the need to
|
||||
modify any configuration files:
|
||||
|
||||
```nix
|
||||
{ pkgs ? import <nixpkgs> {}
|
||||
}:
|
||||
|
||||
pkgs.rstudioWrapper.override {
|
||||
packages = with pkgs.rPackages; [ dplyr ggplot2 reshape2 ];
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Executing `nix-shell` will then drop you into an environment equivalent to the
|
||||
one above. If you need additional packages just add them to the list and
|
||||
re-enter the shell.
|
||||
|
||||
## Updating the package set
|
||||
|
||||
```bash
|
||||
nix-shell generate-shell.nix
|
||||
|
||||
Rscript generate-r-packages.R cran > cran-packages.nix.new
|
||||
mv cran-packages.nix.new cran-packages.nix
|
||||
|
||||
Rscript generate-r-packages.R bioc > bioc-packages.nix.new
|
||||
mv bioc-packages.nix.new bioc-packages.nix
|
||||
```
|
||||
|
||||
`generate-r-packages.R <repo>` reads `<repo>-packages.nix`, therefor the renaming.
|
||||
|
||||
|
||||
## Testing if the Nix-expression could be evaluated
|
||||
|
||||
```bash
|
||||
nix-build test-evaluation.nix --dry-run
|
||||
```
|
||||
|
||||
If this exits fine, the expression is ok. If not, you have to edit `default.nix`

it combined with nix-shell. It will in fact fail to instantiate when invoked

Idris packages
|
||||
==============
|
||||
|
||||
This directory contains build rules for idris packages. In addition,
|
||||
it contains several functions to build and compose those packages.
|
||||
Everything is exposed to the user via the `idrisPackages` attribute.
|
||||
|
||||
callPackage
|
||||
------------
|
||||
|
||||
This is like the normal nixpkgs callPackage function, specialized to
|
||||
idris packages.
|
||||
|
||||
builtins
|
||||
---------
|
||||
|
||||
This is a list of all of the libraries that come packaged with Idris
|
||||
itself.
|
||||
|
||||
build-idris-package
|
||||
--------------------
|
||||
|
||||
A function to build an idris package. Its sole argument is a set like
|
||||
you might pass to `stdenv.mkDerivation`, except `build-idris-package`
|
||||
sets several attributes for you. See `build-idris-package.nix` for
|
||||
details.
|
||||
|
||||
build-builtin-package
|
||||
----------------------
|
||||
|
||||
A version of `build-idris-package` specialized to builtin libraries.
|
||||
Mostly for internal use.
|
||||
|
||||
with-packages
|
||||
-------------
|
||||
|
||||
Bundle idris together with a list of packages. Because idris currently
|
||||
only supports a single directory in its library path, you must include
|
||||
all desired libraries here, including `prelude` and `base`.

Node.js packages
|
||||
================
|
||||
The `pkgs/development/node-packages` folder contains a generated collection of
|
||||
[NPM packages](https://npmjs.com/) that can be installed with the Nix package
|
||||
manager.
|
||||
|
||||
As a rule of thumb, the package set should only provide *end user* software
|
||||
packages, such as command-line utilities. Libraries should only be added to the
|
||||
package set if there is a non-NPM package that requires it.
|
||||
|
||||
When it is desired to use NPM libraries in a development project, use the
|
||||
`node2nix` generator directly on the `package.json` configuration file of the
|
||||
project.
|
||||
|
||||
The package set also provides support for multiple Node.js versions. The policy
|
||||
is that a new package should be added to the collection for the latest stable LTS
|
||||
release (which is currently 6.x), unless there is an explicit reason to support
|
||||
a different release.
|
||||
|
||||
If your package uses native addons, you need to examine what kind of native
|
||||
build system it uses. Here are some examples:
|
||||
|
||||
* `node-gyp`
|
||||
* `node-gyp-builder`
|
||||
* `node-pre-gyp`
|
||||
|
||||
After you have identified the correct system, you need to override your package
|
||||
expression while adding in build system as a build input. For example, `dat`
|
||||
requires `node-gyp-build`, so we override its expression in `default-v6.nix`:
|
||||
|
||||
```nix
|
||||
dat = nodePackages.dat.override (oldAttrs: {
|
||||
buildInputs = oldAttrs.buildInputs ++ [ nodePackages.node-gyp-build ];
|
||||
});
|
||||
```
|
||||
|
||||
To add a package from NPM to nixpkgs:
|
||||
|
||||
1. Modify `pkgs/development/node-packages/node-packages-v6.json` to add, update
|
||||
or remove package entries. (Or `pkgs/development/node-packages/node-packages-v4.json`
|
||||
for packages depending on Node.js 4.x)
|
||||
2. Run the script: `(cd pkgs/development/node-packages && ./generate.sh)`.
|
||||
3. Build your new package to test your changes:
|
||||
`cd /path/to/nixpkgs && nix-build -A nodePackages.<new-or-updated-package>`.
|
||||
To build against a specific Node.js version (e.g. 4.x):
|
||||
`nix-build -A nodePackages_4_x.<new-or-updated-package>`
|
||||
4. Add and commit all modified and generated files.
|
||||
|
||||
For more information about the generation process, consult the
|
||||
[README.md](https://github.com/svanderburg/node2nix) file of the `node2nix`
|
||||
tool.

R packages
|
||||
==========
|
||||
|
||||
## Installation
|
||||
|
||||
Define an environment for R that contains all the libraries that you'd like to
|
||||
use by adding the following snippet to your $HOME/.config/nixpkgs/config.nix file:
|
||||
|
||||
```nix
|
||||
{
|
||||
packageOverrides = super: let self = super.pkgs; in
|
||||
{
|
||||
|
||||
rEnv = super.rWrapper.override {
|
||||
packages = with self.rPackages; [
|
||||
devtools
|
||||
ggplot2
|
||||
reshape2
|
||||
yaml
|
||||
optparse
|
||||
];
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
Then you can use `nix-env -f "<nixpkgs>" -iA rEnv` to install it into your user
|
||||
profile. The set of available libraries can be discovered by running the
|
||||
command `nix-env -f "<nixpkgs>" -qaP -A rPackages`. The first column from that
|
||||
output is the name that has to be passed to rWrapper in the code snipped above.
|
||||
|
||||
However, if you'd like to add a file to your project source to make the
|
||||
environment available for other contributors, you can create a `default.nix`
|
||||
file like so:
|
||||
```nix
|
||||
let
|
||||
pkgs = import <nixpkgs> {};
|
||||
stdenv = pkgs.stdenv;
|
||||
in with pkgs; {
|
||||
myProject = stdenv.mkDerivation {
|
||||
name = "myProject";
|
||||
version = "1";
|
||||
src = if pkgs.lib.inNixShell then null else nix;
|
||||
|
||||
buildInputs = with rPackages; [
|
||||
R
|
||||
ggplot2
|
||||
knitr
|
||||
];
|
||||
};
|
||||
}
|
||||
```
|
||||
and then run `nix-shell .` to be dropped into a shell with those packages
|
||||
available.
|
||||
|
||||
## RStudio
|
||||
|
||||
RStudio uses a standard set of packages and ignores any custom R
|
||||
environments or installed packages you may have. To create a custom
|
||||
environment, see `rstudioWrapper`, which functions similarly to
|
||||
`rWrapper`:
|
||||
|
||||
```nix
|
||||
{
|
||||
packageOverrides = super: let self = super.pkgs; in
|
||||
{
|
||||
|
||||
rstudioEnv = super.rstudioWrapper.override {
|
||||
packages = with self.rPackages; [
|
||||
dplyr
|
||||
ggplot2
|
||||
reshape2
|
||||
];
|
||||
};
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
Then like above, `nix-env -f "<nixpkgs>" -iA rstudioEnv` will install
|
||||
this into your user profile.
|
||||
|
||||
Alternatively, you can create a self-contained `shell.nix` without the need to
|
||||
modify any configuration files:
|
||||
|
||||
```nix
|
||||
{ pkgs ? import <nixpkgs> {}
|
||||
}:
|
||||
|
||||
pkgs.rstudioWrapper.override {
|
||||
packages = with pkgs.rPackages; [ dplyr ggplot2 reshape2 ];
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
Executing `nix-shell` will then drop you into an environment equivalent to the
|
||||
one above. If you need additional packages just add them to the list and
|
||||
re-enter the shell.
|
||||
|
||||
## Updating the package set
|
||||
|
||||
```bash
|
||||
nix-shell generate-shell.nix
|
||||
|
||||
Rscript generate-r-packages.R cran > cran-packages.nix.new
|
||||
mv cran-packages.nix.new cran-packages.nix
|
||||
|
||||
Rscript generate-r-packages.R bioc > bioc-packages.nix.new
|
||||
mv bioc-packages.nix.new bioc-packages.nix
|
||||
```
|
||||
|
||||
`generate-r-packages.R <repo>` reads `<repo>-packages.nix`, therefor the renaming.
|
||||
|
||||
|
||||
## Testing if the Nix-expression could be evaluated
|
||||
|
||||
```bash
|
||||
nix-build test-evaluation.nix --dry-run
|
||||
```
|
||||
|
||||
If this exits fine, the expression is ok. If not, you have to edit `default.nix`
