# Description
|
|
|
|
This folder contains configuration for [Nix](https://nixos.org/), a purely functional package manager used by the Status app for its build process.
|
|
|
|
## Configuration
|
|
|
|
The main config file is [`nix/nix.conf`](/nix/nix.conf) and its main purpose is defining the [binary caches](https://nixos.org/nix/manual/#ch-basic-package-mgmt) which allow download of packages to avoid having to compile them yourself locally.
|
|
|
|
__NOTE:__ If you are in Asia you might want to add the `https://nix-cache-cn.status.im/` to be first in order of `substituters`. Removing `cache.nixos.org` could also help.
|
|
|
|
## Build arguments
|
|
|
|
We leverage the standard nixpkgs `config` argument for our own parameterization of the builds (e.g. to pass a build number or build type).
|
|
|
|
Here is a sample structure of the `config` attribute set:
|
|
|
|
```nix
|
|
config = {
|
|
status-im = {
|
|
build-type = "pr"; # Build type (influences which .env file gets used for feature flags)
|
|
build-number = 9999; # Used for versionCode and CFBundleVersion in Android and iOS respectively
|
|
android = {
|
|
gradle-opts = ""; # Gradle options passed for Android builds
|
|
keystore-path = ""; # Path to keystore for signing the APK
|
|
abi-split = false; # If APKs should be split based on architectures
|
|
abi-include = "x86"; # Android architectures to build for
|
|
};
|
|
status-go = {
|
|
src-override = "$HOME/my/source/status-go"; # local source override
|
|
};
|
|
};
|
|
};
|
|
```
|
|
|
|
## Shell
|
|
|
|
In order to access an interactive Nix shell a user should run `make shell`.
|
|
|
|
The Nix shell is started in this repo via the [`nix/scripts/shell.sh`](/nix/scripts/shell.sh) script, which is a wrapper around the `nix-shell` command and is intended for use with our main [`Makefile`](/Makefile). This allows for an implicit use of `nix-shell` as the default shell in the `Makefile`.
|
|
|
|
Normally the shell starts without any specific target platform, if you want to change that you should export the `TARGET` env variable with appropriate value:
|
|
|
|
```bash
|
|
make shell TARGET=android
|
|
```
|
|
|
|
This way your shell and all other nix commands should run in a setup that is tailored towards Android development.
|
|
|
|
For valid values you can check the [`nix/shells.nix`](/nix/shells.nix) file.
|
|
|
|
## Using a local status-go repository
|
|
|
|
If you need to use a locally checked-out status-go repository, you can achieve that by defining the `STATUS_GO_SRC_OVERRIDE`
|
|
environment variable:
|
|
|
|
```sh
|
|
export STATUS_GO_SRC_OVERRIDE=$GOPATH/src/github.com/status-im/status-go
|
|
make release-android
|
|
```
