# Gemini CLI
An open-source AI agent that brings the power of Gemini directly into your terminal.
View the [*synix* Home Manager module on Forgejo](https://git.sid.ovh/sid/synix/tree/master/modules/home/gemini-cli).

## Setup
The package must be set by you. Easiest option is to use the synix overlay:
```nix
{ inputs, pkgs, ... }:
{
imports = [
inputs.synix.homeModules.gemini-cli
];
programs.gemini-cli = {
enable = true;
package = pkgs.synix.gemini-cli;
};
}
```
Gemini CLI reads environment variables, such as your API key, from `~/.gemini/.env`. You can manage it with sops-nix:
```nix
{ config, ... }:
{
sops.secrets.gemini-api-key = { };
sops.templates.gemini-cli-env = {
content = ''
GEMINI_API_KEY=${config.sops.placeholder.gemini-api-key}
'';
path = config.home.homeDirectory + "/.gemini/.env";
};
}
```
Set `gemini-api-key` in your `secrets.yaml`:
> Replace `abc123` with your Gemini API key.
```yaml
gemini-api-key: abc123
```
## Troubleshooting
These are some common warnings and errors you might encounter when using Gemini CLI:
### Error saving user settings file
```
Error saving user settings file: Error: EROFS: read-only file system, open '/home/you/.gemini/settings.json'
```
This is intended behavior.
