## Installation

### Homebrew (macOS / Linux)

```bash
brew install alexrios/tap/goenv
```

### Download binary

Pre-built binaries for Linux, macOS, and Windows (amd64/arm64) are available on the [Releases](https://github.com/alexrios/goenv/releases) page.

### Using go install

```bash
go install github.com/alexrios/goenv/cmd/goenv@latest
```

### From source

```bash
git clone https://github.com/alexrios/goenv.git
cd goenv
mise run build
bin/goenv
```

## Usage

```bash
# Run the application
goenv

# Run with debug logging (writes to messages.log)
mise run debug

# In another terminal, watch the logs
mise run logs
```

### CLI Mode

goenv can be used non-interactively for scripting and automation:

```bash
goenv --version                          # Show version and Go version
goenv --list                             # List all variables (pipe-friendly)
goenv --get GOPATH                       # Get a single variable value
goenv --set CGO_ENABLED=0 GOOS=linux     # Set one or more variables
goenv --export fish                      # Export as fish shell commands
goenv --export bash --modified           # Export only modified variables as bash
goenv --help                             # Show help
```

Short flags: `-v` (version), `-l` (list), `-h` (help).

Variables marked with `*` in `--list` output are user-modified (via `go env -w`). Export formats: `bash` (default), `fish`, `powershell`, `json`.

```bash
# Use in scripts
GOPATH=$(goenv --get GOPATH)

# Pipe to grep
goenv --list | grep PRIV

# Export modified vars to a file
goenv --export bash --modified > env.sh
```

```json
{
  "sortMode": "alpha",
  "theme": "default",
  "favorites": ["GOPATH", "GOROOT"],
  "watchInterval": 5,
  "maxHistory": 50
}
```

### Configuration Options

| Option | Values | Description |
|--------|--------|-------------|
| `sortMode` | `alpha`, `modified_first`, `category` | How to sort variables in the list |
| `theme` | `default`, `nord`, `dracula`, `light` | Color theme |
| `favorites` | array of strings | Variable names pinned to top |
| `watchInterval` | integer (seconds) | Watch mode reload interval (default: 5, range: 1-86400) |
| `maxHistory` | integer | Maximum undo/redo history entries (default: 50) |

## Snapshots & Presets

### Snapshots

Snapshots capture your current environment state to a JSON file. Use them to:
- Back up your configuration before making changes
- Share environment settings between machines
- Track changes over time

Export with `e`, import with `i`.

### Presets

Presets are named configurations stored in `~/.config/goenv/presets/`. Use them for:
- Switching between development contexts (e.g., CGO on/off)
- Quickly applying common configurations
- Sharing standard setups with your team

goenv ships with five built-in presets: Static Linux Build, WASM Target, Cross-compile ARM64, Debug Verbose, and Minimal Proxy. Built-in presets cannot be deleted.

Manage presets with `p`.

## Themes

goenv includes four color themes:

### Default
The built-in theme with purple/pink accents, suitable for most terminals.

### Nord
Inspired by the [Nord](https://www.nordtheme.com/) color palette. Cool, blue-tinted colors.

### Dracula
Inspired by the [Dracula](https://draculatheme.com/) theme. Rich purples and pinks on a dark background.

### Light
Designed for light terminal backgrounds. Uses high-contrast colors (blue, violet, gray tones) that remain readable on white or light-colored terminals.

![Light Theme demo](https://raw.githubusercontent.com/alexrios/goenv/master/docs/gifs/light-theme.gif)

To change themes, press `t` to cycle through them or edit `~/.config/goenv/config.json`:

```json
{
  "theme": "nord"
}
```

## Environment Variables

goenv organizes variables into categories:

- **General**: GOROOT, GOPATH, GOBIN, GOCACHE, etc.
- **Modules**: GO111MODULE, GOMODCACHE, GOPRIVATE, etc.
- **Proxy/Network**: GOPROXY, GOSUMDB, GOVCS
- **Build**: GOEXE, GOEXPERIMENT, GOTOOLCHAIN
- **CGO**: CGO_ENABLED, CGO_CFLAGS, CC, CXX, etc.
- **Architecture**: GOOS, GOARCH, GOAMD64, GOARM, etc.
- **Tooling**: GOTOOLDIR, GOCOVERDIR
- **Debug/Telemetry**: GODEBUG, GOTELEMETRY

## Data Storage

| File | Purpose |
|------|---------|
| `~/.config/goenv/config.json` | User preferences |
| `~/.config/goenv/history.json` | Undo/redo history |
| `~/.config/goenv/presets/*.json` | Saved presets |

Snapshots are saved to the directory you specify during export.
