# codebase-flattener
Flatten a codebase into a single file for easy LLM ingestion.
---
**Features:**
- Recursively walk your project, respecting `.gitignore`, `.llmignore`, and custom ignore rules.
- Skip the output file itself to avoid self-inclusion.
- Follow or ignore symlinks via a flag.
- Overridable output filename (default: `codebase.txt`).

## 📦 Installation
Ensure you have Rust and Cargo installed (edition 2021).
```bash
# Install from crates.io
cargo install codebase-flattener
```
Or build locally:

git clone https://github.com/youruser/codebase-flattener.git
cd codebase-flattener
cargo build --release
# The binary will be in target/release/
```
---
## 🚀 Usage
```bash
# Run with defaults (respects .gitignore & .llmignore, follows symlinks)
codebase-flattener
# Add custom ignore files
codebase-flattener --ignore extra.ignore --ignore temp.ignore
# Disable all default ignore files
codebase-flattener --no-default-ignores --ignore only.ignore
# Don’t follow symlinks
codebase-flattener --no-follow
# Change the output filename
codebase-flattener --output project_dump.txt
```
By default, all files are dumped into `codebase.txt` with separators:
```
<<< FILE: path/to/file.ext >>>
<file contents>
```
