# gcpath

`gcpath` is a CLI utility to query Google Cloud Platform resource hierarchy paths.
It helps you translate between GCP resource names (e.g., `folders/12345`) and human-readable paths (e.g., `//example.com/department/team`).

## Why should I use gcpath?

- familiar linux-like CLI
- you can stay in the terminal for quick resource hierarchy lookups
- no need to learn the complex `gcloud` interface
- look-up only commands, so coding agents can't do harm using it

## Features

- **Tree Visualization**: View your hierarchy as a tree.
- **Recursive Listing**: List all folders and projects in your organization as paths.
- **Path Resolution**: Get the resource name (ID) for a given path.
- **Reverse Lookup**: Get the path for a given resource name (ID).
- **Dual Mode**:
  - **Cloud Asset API (Default)**: Fast, bulk loading using GCP Cloud Asset Inventory.
  - **Resource Manager API**: Iterative loading using standard Resource Manager API (slower, but different permissions).

### Roadmap

- ~~caching, for lightning fast lookups~~
- ~~diagram generation~~
- ~~entrypoint configuration (organization or folder)~~
- IAM policies
- other resources

## Prerequisites

### Authentication

`gcpath` uses [Google Cloud Application Default Credentials (ADC)](https://cloud.google.com/docs/authentication/provide-credentials-adc).

1. Install [gcloud CLI](https://cloud.google.com/sdk/docs/install).
2. Authenticate:

   ```bash
   gcloud auth application-default login
   ```

### Permissions

Ensure you have enough permissions on your entrypoint (organization or folder), see [API modes](#api-modes).

### Quick Start

```bash
# List all resources
gcpath ls

# List children of a specific folder
gcpath ls folders/123456789

# Find ID of a specific path
gcpath name //example.com/engineering

# Find path of a specific resource ID
gcpath path folders/123456789

# View tree rooted at organization
gcpath tree

# View tree rooted at folder
gcpath tree folders/123456789

# Generate a Mermaid diagram of the hierarchy
gcpath diagram

# Generate a D2 diagram scoped to a folder
gcpath diagram folders/123456789 --format d2
```

## Usage

### List Resources (`ls`)

List folders and projects. Defaults to the organization root.

```bash
gcpath ls [RESOURCE_NAME]
```

Options:

- `-l, --long`: Show resource IDs and numbers (for projects).
- `-R, --recursive`: List resources recursively.

Examples:

```bash
# List all organizations and their top-level children
gcpath ls

# List all contents of an organization recursively
gcpath ls -R

# List children of a specific folder
gcpath ls folders/123456789
```

### Tree View (`tree`)

Visualize the resource hierarchy in a tree format.

```bash
gcpath tree [RESOURCE_NAME]
```

Options:

- `-L, --level N`: Limit depth of the tree (no limit by default).
- `-i, --ids`: Include resource IDs in the output.
- `-y, --yes`: Skip confirmation prompts for large hierarchy loads.

### Generate Diagram (`diagram`)

Generate a [Mermaid](https://mermaid.js.org/) or [D2](https://d2lang.com/) diagram of the resource hierarchy.

```bash
gcpath diagram [RESOURCE_NAME]
```

Options:

- `-f, --format FORMAT`: Output format: `mermaid` (default) or `d2`.
- `-L, --level N`: Limit depth of the diagram.
- `-i, --ids`: Include resource IDs in node labels.
- `-o, --output FILE`: Write diagram to a file instead of stdout.
- `-y, --yes`: Skip confirmation prompts for large hierarchy loads.

Examples:

```bash
# Generate Mermaid diagram of the full hierarchy
gcpath diagram

# Generate D2 diagram scoped to a folder
gcpath diagram folders/123456789 --format d2

# Save Mermaid diagram to a file with depth limit
gcpath diagram -L 3 -o hierarchy.mmd

# Include resource IDs in labels
gcpath diagram --ids
```

### Get Resource Name (`name`)

Get the GCP resource name (e.g., `folders/123`) from a path:

```bash
gcpath name //example.com/engineering/backend
```

To get just the ID:

```bash
gcpath name --id //example.com/engineering/backend
```

### Get Path (`path`)

Get the path from a resource name:

```bash
gcpath path folders/987654321
```

## API Modes

gcpath supports two GCP APIs for loading resource hierarchy data:

### Cloud Asset API (Default - Recommended)

Fast bulk loading via Cloud Asset Inventory. Recommended for most users.

```bash
# Use Cloud Asset API (default)
gcpath ls
gcpath ls --use-asset-api  # explicit
gcpath ls -u               # short form
```

**Advantages:**

- 5-6x faster than Resource Manager API
- Supports scoped loading (`ls folders/123`, `tree folders/123`)
- Efficient for large hierarchies (1000+ folders)

**Required Permissions:**

- `cloudasset.assets.searchAllResources`
- `resourcemanager.organizations.get`
- `resourcemanager.folders.get`
- `resourcemanager.projects.get`

**Setup:** Requires Cloud Asset API to be enabled: `gcloud services enable cloudasset.googleapis.com`

### Resource Manager API

Traditional recursive API calls. Use when Cloud Asset API is not available.

```bash
# Use Resource Manager API
gcpath ls --no-use-asset-api
gcpath ls -U  # short form
```

**Advantages:**

- Works without Cloud Asset API enabled
- Simpler permission model
- Standard `resourcemanager.*` permissions

**Required Permissions:**

- `resourcemanager.organizations.get`
- `resourcemanager.folders.list`
- `resourcemanager.projects.list`
- `resourcemanager.projects.get`

### Which Should I Use?

- **For most users:** Use the default (Cloud Asset API) for best performance
- **If you get permission/API errors:** Use `-U` flag for Resource Manager API

## Entrypoint Configuration

If you're a folder admin without organization-level access, or simply want to focus on a specific part of the hierarchy, you can configure an **entrypoint**. This scopes all commands to a subtree, improving performance and relevance.

### Setting an Entrypoint

```bash
# Set a default entrypoint (persisted in ~/.gcpath/config.json)
gcpath config set-entrypoint folders/123456789

# Show current configuration
gcpath config show

# Remove the entrypoint
gcpath config clear-entrypoint
```

### One-off Override

Use the `--entrypoint` / `-e` flag to override the configured entrypoint for a single command:

```bash
gcpath -e folders/987654321 ls
gcpath -e folders/987654321 tree
```

### Behavior

- When an entrypoint is set, commands like `ls`, `tree`, `diagram`, and `name` automatically scope to that resource.
- Passing an explicit resource argument overrides the entrypoint:

  ```bash
  gcpath ls folders/555  # uses folders/555, not the configured entrypoint
  ```

- The cache is **scope-aware**: cached data stores which entrypoint it was built for. Changing the entrypoint automatically invalidates the cache and triggers a fresh load.
