dumpcat 0.1.2

Dump a directory's file tree and contents into a single formatted output — built for LLM prompts.

dumpcat

Dump a directory's file tree and contents into a single formatted output — built for LLM prompts.

Highlights

• One command to dump your entire codebase (or a filtered slice of it) into a single output
• Smart defaults — respects .gitignore, skips binaries, limits file sizes
• Three output formats — Markdown, plain text, or JSON
• Filterable — by extension, glob pattern, depth, and file size
• Clipboard ready — copy output directly with -c
• Prompt-friendly — prepend/append text or template files for LLM context
• Configurable — project-level .dumpcat.toml with named profiles
• Zero bloat — one runtime dependency (pathspec), everything else is stdlib

Installation

Requires Python 3.11+.

uv tool install dumpcat

# Or with pip
pip install dumpcat

# Or with pipx
pipx install dumpcat

Quick start

# Dump current directory as Markdown
dumpcat

# Only Python files, 2 levels deep
dumpcat -d 2 -i .py

# Prepend a prompt and copy to clipboard
dumpcat -i .py -c -p "Review this code for security issues"

# Plain text with stats
dumpcat -f plain -s

# Just the tree structure
dumpcat --tree-only

# JSON output for tooling
dumpcat -f json --no-tree

Output

dumpcat renders file contents followed by a file tree:

# File Contents

## `src/main.py`

```python
import sys

def main():
    print("hello")
```

# File Tree

```
.
├── src/
│   ├── main.py
│   └── utils/
│       └── helpers.py
└── README.md
```

See the output formats documentation for Markdown, plain text, and JSON examples.
