* Detect BPM and Key of audio files
* Write detected BPM and Key to metadata tags
* Generate CSV reports of analyzed tracks
+* Save track metadata to a database
## Building
## Usage
```sh
-./target/release/virittaa [OPTIONS] <PATH>...
+./target/release/virittaa [OPTIONS] [PATH]...
```
### Arguments
-* `<PATH>...`: One or more files or directories to analyze.
+* `[PATH]...`: One or more files or directories to analyze. Not required when using `--list` or `--query`.
### Options
* `-f`, `--force`: Re-analyze files even if they already have BPM/Key tags.
* `-j`, `--jobs <JOBS>`: Number of threads to use (0 = all cores).
* `-r`, `--report`: Generate a CSV report with timestamped filename.
+* `-S`, `--save`: Save track reports (artist, track, BPM, key) to the database.
+* `-l`, `--list`: List all track reports stored in the database.
+* `--query <PATH>`: Look up a track report by file path.
+* `--db-path <PATH>`: Path to the database directory (default: `~/.local/share/virittaa.db`).
* `-h`, `--help`: Print help information.
* `-V`, `--version`: Print version information.
-### Example
+### Examples
```sh
# Analyze a single file
# Generate a CSV report
./target/release/virittaa --report /path/to/music/
+
+# Analyze and save reports to database
+./target/release/virittaa --save /path/to/music/
+
+# Write tags and save to database with custom path
+./target/release/virittaa -w --save --db-path ~/my_library.db /path/to/music/
+
+# Generate CSV report and save to database
+./target/release/virittaa -r --save /path/to/music/
+
+# List all tracks in the database
+./target/release/virittaa --list
+
+# Look up a specific track by file path
+./target/release/virittaa --query /path/to/track.flac
+
+# Query using a custom database path
+./target/release/virittaa --list --db-path ~/my_library.db
