# Optional dependencies — install only if you use the corresponding feature.
# The app handles their absence gracefully (clear error message on first use).
#
# Note: chromadb-client + fastembed moved to requirements.txt — RAG, semantic
# memory, and tool selection are core paths, so they ship by default now.

# Local speech-to-text (microphone -> text) via faster-whisper, for the
# "local" STT provider. Runs on CPU out of the box (CTranslate2 backend, no
# torch needed). Install if you want to dictate/transcribe with the mic
# without sending audio to an external endpoint.
# Optional extra: install `torch` too if you have a CUDA GPU and want
# GPU-accelerated transcription — it's auto-detected, CPU is used otherwise.

# Local text-to-speech via Kokoro-82M for the "local" TTS provider.
# Kokoro 0.9.4 declares Python >=3.10,<3.13; Odysseus itself requires 3.11+,
# so pip installs these extras on 3.11-3.12 and deliberately skips them on
# Python 3.13+ (including the Python 3.14 container image). Kokoro declares
# torch; the local provider still
# requires a CUDA-enabled torch build and GPU at runtime. SoundFile is separate
# in Kokoro's official install instructions and is not a transitive dependency.

# DuckDuckGo as a search provider option.
# Install if you want DDG in the search-provider dropdown.

# PDF form-filling feature (fillable AcroForm detection, field extraction,
# value/annotation/signature stamping, page rendering for the form overlay).
# NOTE: PyMuPDF is AGPL-3.0. Installing it brings AGPL obligations for a
# network-served app — see ACKNOWLEDGMENTS.md. The MIT core (PDF *text*
# extraction via pypdf) works without it; this only unlocks form-filling.

# Office / EPUB document text extraction (chat attachments + the personal-docs
# RAG index). markitdown (MIT, Microsoft) converts .docx/.xlsx/.pptx/.xls/.epub
# to Markdown — more token-efficient and model-legible than a raw dump. Optional
# and lazy-imported via src/markitdown_runtime.py; without it those formats fall
# back to a friendly "install to extract" banner and the core stays pure-MIT.
# Extras pull mammoth/lxml/python-pptx/pandas/openpyxl/xlrd; the base also pulls
# magika (onnxruntime), already a core dep via fastembed. We avoid the
# [all]/Azure/audio extras (cloud + heavy). Pinned to a release >30 days old per
# the dependency-age discussion in issue #485.
