Render a repo into one LLM-ready text file

Pytoma — Repo text rendering

Pytoma condenses your python repo into one concise, LLM-friendly, text file. You choose what to show (full code, signature + docstring, partial bodies ...) per function, class, file, or folder.

You can configure what will be shown via a small YAML config or CLI options, and the output is a single text file divided in fenced code blocks, ideal for prompting an LLM or sharing a focused snapshot with collaborators. You can also use it to hide sensitive code snippets to protect your innovative ideas.

Note from the author : I originally vibe-coded a basic tool for myself because ChatGPT wouldn't accept more than 10 files and the files-to-prompts lib didn't allow me to hide certain sections ... but it turned out to be very handy and useful, so I refined it and it became this project.

Highlights

• Policy-driven slicing: full, sig, sig+doc, body:levels=k, hide to omit sections, file:no-imports to omit imports

• Targets:

  • by qualname (e.g. pkg.mod:Class.method or pkg.mod:*),
  • by path glob (e.g. **/repo/pkg/**/*.py),
  • or via a global default.

• Multiple engines:

  • Python (.py): granular per function/method/class.
  • Markdown (.md): per heading or whole document (supports full/hide).
  • YAML will soon be added
  • A description or short extract of heavy files, ML artifacts, etc., is also to be expected

Installation

pip install pytoma

---

Quick Start (CLI)

# Basic: pack a repo with defaults (same behaviour as files-to-prompt)
pytoma ./path/to/repo > PACK.txt

# Now we use a YAML config to customize the render (skip sections, etc.)
pytoma ./repo --config config.yml --out PACK.txt

The pack looks like:

### pkg/module.py

```python
def foo(a: int, b: int) -> int:
    """Adds two numbers."""
    # … lines 12–37 body omitted (26 lines) …
```

### docs/guide.md

<!-- … lines 1–120 document omitted (120 lines) … -->

---

Configuration (YAML)

# config.yml
default: full        # fallback policy

# optional: exclude patterns (relative to the provided roots)
excludes:
  - ".venv/**"
  - "**/__pycache__/**"
  - "dist/**"
  - "build/**"
  - "site-packages/**"
  - "**/*.pyi"

rules:
  # Apply a file-level filter first (removes top-level imports, keeps __future__)
  - match: "/abs/path/to/repo/pkg/**/*.py"
    mode: "file:no-imports"

  # Then apply function-level policy to the same files
  - match: "/abs/path/to/repo/pkg/**/*.py"
    mode: "sig+doc"

  # Hide an entire module (replaced by an omission marker)
  - match: "/abs/path/to/repo/legacy/big_module.py"
    mode: "hide"

  # Target all defs in a given module by qualname
  - match: "pkg.special:*"
    mode: "body:levels=1"

  # Markdown supports only "full" and "hide"
  - match: "/abs/path/to/repo/README.md"
    mode: "hide"

Note : when Pytoma walks each document’s nodes, it decides a policy with this order: qualname rules > path rules > global default.

---

Policies

• full — leave the node as is.

• hide — remove and insert an omission marker:

  • On a module: replaces the whole file content.
  • On a class: replaces the whole class block.
  • On a function/method: replaces the definition or its body depending on engine mode.

• sig — one-line header (def …:), body omitted with a marker.

• sig+doc — header + docstring (or """…""" placeholder), body omitted.

• body:levels=k — keep code with indentation ≤ base + 4*k, collapse deeper blocks with markers.

• file:no-imports — strip top-level import/from … import … except from __future__ import ….

Markers are comment-style lines (or a light box) with line counts, e.g.:

# … lines 42–97 body omitted (56 lines) …

---

Applying a policy to a whole file or folder

Three options:

1. Global default

pytoma /abs/repo --default "sig+doc"

2. Path glob rule (absolute POSIX)

rules:
  - match: "/abs/repo/pkg/**/*.py"
    mode: "sig+doc"

3. Qualname wildcard for a module

rules:
  - match: "pkg.module:*"
    mode: "sig+doc"

For file-level effects like removing imports or hiding an entire file, use file:no-imports or hide on the path glob; these apply to the module root.

Excludes

By default, Pytoma skips:

.venv/**, **/__pycache__/**, dist/**, build/**, site-packages/**, **/*.pyi

You can override in config.yml → excludes.

---

Pitfalls

• Rule order can still be tricky when several rules are about the same file. I'm looking forward to improving that soon. For the moment, prefer being as explicit as possible, and for tricky setups, you can simply ask an LLM to draft the rules for you (from your repo tree and goals).
• To name a markdown section in the config file, you still need to give the slugified version of the section

Roadmap

• Engine for YAML / JSON (keys/tables granularity), CSV (short preview like pandas does), etc.
• Better summary of skipped lines (for instance, when skipping imports, in the examples of skipped imports, we should probably prioritize unexpected imports over classic ones such as sys, os ...)
• Propose the automatic addition of inferred rules: in particular, functions that are only called by hidden functions should probably be hidden by default.
• More markers + Let the user choose their markers, rule by rule, using the configuration
• A “custom:alternative_version” rule to simply replace a block with an alternative version of the block provided by the user.
• Heuristics to suggest rules (and possibility to condition it by a section which we want to focus on) -> may actually become another independent tool ...
• ... and even smarter module targeting via dependency graphs , embeddings, git edit correlations, etc.

Current engines & support matrix

Engine / Mode	full	hide	sig	sig+doc	body:levels=k	file:no-imports
Python (.py)	✅	✅	✅	✅	✅	✅
Markdown (.md)	✅	✅	–	–	–	–

Planned: YAML/TOML section policies (toml already started)

---

How it works (short)

• Each engine parses a file into a lightweight IR:

  • Document with a flat list of Nodes (module, class, function, etc.).

• A decision step maps nodes to Actions (full, sig+doc, …) using the precedence above.

• Engines render actions into concrete Edits (byte spans + replacements).

• Edits are merged.

• The final pack concatenates per-file sections with language fences.
