## What is Insight-TF?

Insight-TF turns your Terraform workflow into a fully interactive TUI — browse state, inspect resources, plan, apply, detect drift, estimate costs, and scaffold new resources, all from a single terminal window.

## Installation

Choose the method that suits you best.

### Option 1 — Download a Binary (No Python required)

Pre-built binaries are available for **Linux** and **Windows** on the [Releases page](https://github.com/bhuvan-raj/TerraLens/releases).

**Linux:**
```bash
# Download the latest binary
curl -L https://github.com/bhuvan-raj/TerraLens/releases/latest/download/insight-tf-linux -o insight-tf

# Make it executable
chmod +x insight-tf

# Run it from your Terraform project directory
cd ~/my-terraform-project
./insight-tf
```

**Windows:**
```powershell
# Download insight-tf-windows.exe from the Releases page, then run:
.\insight-tf-windows.exe
```

> No Python, no pip, no dependencies — everything is bundled inside the binary.

---

### Option 2 — Install via pip (Python users)

Insight-TF is published on [PyPI](https://pypi.org/project/insight-tf/):

```bash
pip install insight-tf
```

Then run it from your Terraform project directory:

```bash
cd ~/my-terraform-project
insight-tf

# Or pass the state file path explicitly
insight-tf /path/to/terraform.tfstate
```

---

### Option 3 — Install from Source

```bash
# 1. Clone the repository
git clone https://github.com/bhuvan-raj/Insight-Q.git
cd Insight-Q

# 2. Create a virtual environment
python3 -m venv .venv
source .venv/bin/activate      # Windows: .venv\Scripts\activate

# 3. Install dependencies
pip install -r requirements.txt
```

---

### ⚠️ Required: Run the Setup Script

Regardless of which installation method you use, **you must run `setup.py` once** before launching the app for the first time:

```bash
python setup.py
```

The setup script automatically:
- Checks Python 3.10+
- Installs `textual` and `rich`
- Checks for Terraform in `PATH`
- Downloads and installs **Infracost** for your platform (Linux / macOS / Windows)
- Guides you through Infracost authentication (free — no credit card required)
- Writes `.insight-tf.json` with resolved binary paths

> **Why is this needed?** Infracost (used for cost estimation) requires authentication and its binary path needs to be recorded so Insight-TF can find it at runtime.

## Quick Start

### 1. Clone the repository

```bash
git clone https://github.com/bhuvan-raj/Insight-Q.git
cd Insight-Q
```

### 2. Create a virtual environment

```bash
python3 -m venv .venv
source .venv/bin/activate      # Windows: .venv\Scripts\activate
```

### 3. Run the setup script

```bash
python setup.py

## Usage Guide

### Keyboard Shortcuts

| Key | Action |
|---|---|
| `1` | Switch to Overview tab |
| `2` | Switch to Manage tab |
| `r` | Reload state from disk |
| `q` | Quit |
| `Esc` | Close any open modal or wizard |

### Overview Tab

Displays a high-level snapshot of your infrastructure:

- **Terraform version** — read directly from the state file
- **State serial** — increments on every apply; useful for auditing
- **Total resources** — count of all managed resources
- **Provider count** — number of unique providers in use
- **Resource table** — type, name, provider, and instance count for every resource

### Manage Tab

#### Resource Tree

The left panel shows all managed resources grouped by type. Click any resource leaf to load its full attribute map in the right panel, including nested maps and lists rendered as structured text.

#### Action Buttons

**➕ Add Resource**
Opens a 3-step wizard:
1. **Select provider** — AWS supported; Azure, GCP, Oracle, Docker, Kubernetes coming soon
2. **Browse resources** — 334 AWS resources across 20 categories with live search and category sidebar
3. **Configure & preview** — fill in fields, review the generated HCL, then choose:
   - **💾 Write File** — saves the `.tf` file and runs `terraform plan` to validate
   - **🚀 Write & Apply** — saves the file, plans, then immediately applies

**🔍 Plan**
Streams the full output of `terraform plan -no-color` into the output panel in real time.

**💰 Cost Estimate**
Runs `infracost breakdown --path . --format json` and renders a formatted cost table:

```
  Resource                                            Monthly
  ────────────────────────────────────────────────────────────
  aws_db_instance.main (db.t3.medium)               $  63.22
  aws_instance.web (t3.micro)                       $   8.47
  aws_s3_bucket.assets                          usage-based
  ────────────────────────────────────────────────────────────
  TOTAL MONTHLY ESTIMATE                            $  71.69
```

**🔄 Detect Drift**
Runs `terraform plan -refresh-only -detailed-exitcode` and reports:
- ✅ **No drift** — infrastructure matches state exactly
- ⚠️ **Drift found** — lists each drifted resource with its status (changed / deleted outside Terraform / created outside Terraform)
- ❌ **Error** — shows full stderr output for debugging

**🗑️ Destroy Selected**
Select a resource leaf in the tree, click Destroy. A confirmation modal displays the full resource address (`type.name`) before executing `terraform destroy -target=<addr> -auto-approve`.

**⚡ Apply Now**
Runs `terraform apply -auto-approve -no-color` from the project directory. Streams all output in real time and automatically reloads the resource tree on success.

All other resources generate a scaffold HCL block with a direct link to the Terraform registry documentation for that resource type.

---

## Configuration

`.insight-tf.json` is written by `setup.py` and read at startup to locate binaries:

```json
{
  "infracost_path": "/usr/local/bin/infracost",
  "terraform_path": "/usr/local/bin/terraform",
  "setup_complete": true
}
```

Edit this file manually if your binaries are in non-standard locations.

---

## Extending Insight-TF

### Add a guided form for a new resource type

Add an entry to `RESOURCE_TEMPLATES` in `insight_tf.py`:

```python
RESOURCE_TEMPLATES["aws_elasticache_cluster"] = {
    "description": "ElastiCache Redis/Memcached cluster",
    "fields": [
        {"name": "resource_name", "label": "Resource name",  "placeholder": "my_cache",       "required": True,  "default": ""},
        {"name": "cluster_id",    "label": "Cluster ID",     "placeholder": "my-redis-cluster","required": True,  "default": ""},
        {"name": "engine",        "label": "Engine",         "placeholder": "redis",           "required": True,  "default": "redis"},
        {"name": "node_type",     "label": "Node type",      "placeholder": "cache.t3.micro",  "required": True,  "default": "cache.t3.micro"},
        {"name": "num_nodes",     "label": "Num cache nodes","placeholder": "1",               "required": True,  "default": "1"},
    ],
    "template": '''resource "aws_elasticache_cluster" "{resource_name}" {{
  cluster_id           = "{cluster_id}"
  engine               = "{engine}"
  node_type            = "{node_type}"
  num_cache_nodes      = {num_nodes}
}}\n''',
}
```

### Add a new cloud provider

In the `PROVIDERS` list, add your entry with `"supported": True`:

```python
{"id": "digitalocean", "name": "DigitalOcean", "icon": "🌊", "supported": True},
```

Then handle the new provider ID in `on_provider_selected` inside `add_resource`:

```python
if provider == "digitalocean":
    self.app.push_screen(DOResourcePickerScreen(), on_resource_picked)
```

---

## Troubleshooting

**`MountError: duplicate ID`**
A widget ID collision — ensure you are on the latest version. Run `git pull` and restart.

**`terraform not found`**
```bash
which terraform       # verify it's in PATH
terraform version     # verify it runs
```

**`infracost not found` in Cost Estimate**
```bash
python setup.py       # re-run to auto-install
```

**`not authenticated` in Cost Estimate**
```bash
infracost auth login
```

**State not updating after apply / destroy**
Press `r` to manually reload. Ensure your backend writes a local `terraform.tfstate` or pull remote state first with `terraform state pull > terraform.tfstate`.

**App is slow to open the Add Resource wizard**
The catalog mounts 334 buttons at once. On very slow terminals, switch to the Manage tab first to let the app fully initialise before clicking Add Resource.

---
