# Project_Journal

A structured journaling system with encrypted monthly vaults, desktop UI, CLI tools, and optional AI-assisted analysis.

## Support Matrix

- Python: `3.14`
- Platforms: Windows and Linux (first-class), macOS (best effort)
- Default profile: CPU
- Optional profiles: GPU, optional NLP backend

## Dependency Profiles

- `requirements_base.txt`: shared Journal runtime dependencies
- `requirements_cpu_only.txt`: base + CPU AI stack
- `requirements_gpu.txt`: base + GPU AI stack
- `requirements_nlp_optional.txt`: optional spaCy backend (auto-fallback if unavailable)

## Quickstart

### Linux (CPU default)

```bash
cd Project_Journal
python3.14 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install --extra-index-url https://download.pytorch.org/whl/cpu -r requirements_cpu_only.txt
```

### Linux (GPU optional)

```bash
cd Project_Journal
python3.14 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements_gpu.txt
```

### Windows PowerShell (CPU default)

```powershell
cd Project_Journal
py -3.14 -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip
python -m pip install --extra-index-url https://download.pytorch.org/whl/cpu -r requirements_cpu_only.txt
```

On Windows + Python 3.14, `pywebview` is intentionally skipped due upstream
`pythonnet` build compatibility. `run_desktop.py` will auto-fallback to opening
the app in your system browser.

### Optional NLP backend (spaCy)

```bash
python -m pip install -r requirements_nlp_optional.txt
python -m spacy download en_core_web_sm
```

If spaCy is missing or unsupported, Journal now auto-falls back to built-in NLP heuristics.
On current Python 3.14 environments, this optional install may be skipped due upstream spaCy compatibility.

## Running

### Desktop App

```bash
python ./journal/run_desktop.py
```

### CLI

```bash
python -m journal.cli.main --help
python -m journal.cli.main vault load
python -m journal.cli.main search "your query"
```

## NLP Backend Control

Set `JOURNAL_NLP_BACKEND` to choose behavior:

- `auto` (default): use spaCy when available, else fallback
- `spacy`: require spaCy backend and fail clearly if unavailable
- `fallback`: always use fallback heuristics

Examples:

```bash
export JOURNAL_NLP_BACKEND=fallback
python ./journal/run_desktop.py
```

```powershell
$env:JOURNAL_NLP_BACKEND = "spacy"
python .\journal\run_desktop.py
```

## Installer Script

Use the Linux helper script:

```bash
./installreqs.sh
./installreqs.sh --gpu
./installreqs.sh --with-nlp
```

## Notes

- Decrypted journal data in `journal/data` is cleared on graceful shutdown.
- Vault save/load commands remain unchanged.
