# Profiles
|
||
|
|
Profiles are simply NixOS modules which contain generic expressions suitable
|
||
|
|
for any host. A good example is the configuration for a text editor, or
|
||
|
|
window manager. If you need some concrete examples, just checkout the
|
||
|
|
community [branch](https://github.com/nrdxp/nixflk/tree/community/profiles).
|
||
|
|
|
||
|
|
## Constraints
|
||
|
|
For the sake of consistency, there are a few minor constraints. First of all, a
|
||
|
|
profile should always be defined in a `default.nix`, and it should always be a
|
||
|
|
a function taking a single attribute set as an argument, and returning a NixOS
|
||
|
|
module which does not define any new module options. If you need to make new
|
||
|
|
module option declarations, just use [modules](../modules).
|
||
|
|
|
||
|
|
These restrictions help simplify the import logic used to pass profles to
|
||
|
|
[suites](../suites).
|
||
|
|
|
||
|
|
### Example
|
||
|
|
#### Correct ✔
|
||
|
|
profiles/develop/default.nix:
|
||
|
|
```nix
|
||
|
|
{ ... }:
|
||
|
|
{
|
||
|
|
programs.zsh.enable = true;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Incorrect ❌
|
||
|
|
profiles/develop.nix:
|
||
|
|
```nix
|
||
|
|
{
|
||
|
|
options = {};
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Subprofiles
|
||
|
|
Profiles can also define subprofiles. They follow the same constraints outlined
|
||
|
|
above. A good top level profile should be a high level concern, such a your
|
||
|
|
personal development environment, and the subprofiles should be more concrete
|
||
|
|
program configurations such as your text editor, and shell configs. This way,
|
||
|
|
you can either pull in the whole development profile, or pick and choose
|
||
|
|
individual programs.
|
||
|
|
|
||
|
|
## Conclusion
|
||
|
|
Profiles are the most important concept in nixflk. They allow us to keep our
|
||
|
|
nix expressions self contained and modular. This way we can maximize reuse
|
||
|
|
while minimizing boilerplate. Always strive to keep your profiles as generic
|
||
|
|
and modular as possible. Anything machine specific belongs in your
|
||
|
|
[host](../hosts) files.
