# Marlin
|
||||
|
||||
**Marlin** is a lightweight, metadata-driven file indexer you run on your own
|
||||
machine. It scans folders, stores paths and basic stats in a local SQLite
|
||||
database, and lets you tag files from the command line.
|
||||
**Marlin** is a lightweight, metadata-driven file indexer that runs entirely on
|
||||
your computer.
|
||||
It scans folders, stores paths and file stats in SQLite, lets you add
|
||||
hierarchical **tags** and **custom attributes**, takes automatic snapshots, and
|
||||
offers instant full-text search with FTS5.
|
||||
Nothing ever leaves your machine.

|
||||
This repo contains the **Sprint-0 foundation**:
|
||||
## Feature highlights
|
||||
|
||||
* XDG-aware config — no hard-coded paths
|
||||
* Embedded SQLite migrations (WAL mode)
|
||||
* Fast directory scanner (now accepts *multiple* paths in one call)
|
||||
* Simple tagging tool
|
||||
* Human-readable logging via `tracing`
|
||||
| Area | What you get |
|
||||
|----------------|---------------------------------------------------------------------------------|
|
||||
| **Safety** | Timestamped backups `marlin backup` and one-command restore `marlin restore` |
|
||||
| **Upgrades** | Automatic schema migrations + dynamic column adds |
|
||||
| **Indexing** | Fast multi-path scanner (WAL mode) |
|
||||
| **Metadata** | Hierarchical tags (`project/alpha`) & key-value attributes (`reviewed=yes`) |
|
||||
| **Search** | Prefix-aware FTS5, optional `--exec` action per hit |
|
||||
| **DX / Logs** | Readable tracing (`RUST_LOG=debug …`) |

````
|
||||
|
||||
1. `marlin scan <PATHS>...` walks each directory tree, gathers size and
|
||||
modification time, then upserts rows into **`files`**.
|
||||
2. `marlin tag "<glob>" <tag>` looks up each matching file row and inserts
|
||||
junction rows into **`file_tags`**. New tag names are created on the fly.
|
||||
3. You can open the DB yourself
|
||||
(`sqlite3 ~/.local/share/marlin/index.db`) while search and GUI features
|
||||
are still under construction.

| --------------------------- | ----------------------------------------------------------------------------------------------------- |
|

| `marlin init` | Safe to run repeatedly; applies pending migrations. |
|
||||
| `marlin scan <PATHS>...` | Accepts any number of absolute/relative paths. Directories you can’t read are skipped with a warning. |
|
||||
| `marlin tag "<glob>" <tag>` | Quote the glob so your shell doesn’t expand it. Uses `glob` crate rules (`**` for recursive matches). |

||||
### Attribute subcommands

||||

||||
| Command | Example |
|
||||
| ---------- | ------------------------------------------------ |

## Backups & restore
|
||||
|
||||
* **Create snapshot**
|
||||
|
||||
```bash
|
||||
marlin backup
|
||||
# → ~/.local/share/marlin/backups/backup_2025-05-14_22-15-30.db
|
||||
```
|
||||
|
||||
* **Restore snapshot**
|
||||
|
||||
```bash
|
||||
marlin restore ~/.local/share/marlin/backups/backup_2025-05-14_22-15-30.db
|
||||
```
|
||||
|
||||
Marlin automatically takes a safety backup before any schema migration.

||||

|
||||
|
||||
## Upgrading to a new build
|
||||
|
||||
During development you’ll be editing source files frequently. Two common ways
|
||||
to run the updated program:
|
||||
|
||||
### 1. Run straight from the project directory
|
||||
|
||||
```bash
|
||||
cargo run --release -- scan ~/Pictures
|
||||
cargo install --path . --force # rebuild & overwrite installed binary
|
||||
```
|
||||
|
||||
*Cargo recompiles what changed and runs the fresh binary located in
|
||||
`target/release/marlin`.*
|
||||
|
||||
### 2. Replace the global copy
|
||||
|
||||
If you previously installed Marlin (e.g. into `~/.cargo/bin/` or `/usr/local/bin/`),
|
||||
overwrite it:
|
||||
|
||||
```bash
|
||||
cargo install --path . --force
|
||||
```
|
||||
|
||||
Now `which marlin` should print the new location, and multi-path scan works:
|
||||
|
||||
```bash
|
||||
marlin scan ~/Pictures ~/Documents …
|
||||
```
|
||||
|
||||
If the CLI still shows the old single-path usage (`Usage: marlin scan <PATH>`),
|
||||
you’re invoking an outdated executable—check your `PATH` and reinstall.
|
||||
|
||||
---
|
||||
|
||||
## Development tips
|
||||
|
||||
* Tight loop: `cargo watch -x 'run -- scan ~/Pictures'`
|
||||
* Debug logs: `RUST_LOG=debug marlin scan ~/Pictures`
|
||||
* Lint: `cargo clippy --all-targets --all-features -D warnings`
|
||||
* Tests: `cargo test`
|
||||
Backups + dynamic migrations mean your data is preserved across upgrades.

# Marlin Usage Tutorial
|
||||
|
||||
Below is a hands-on lab you can run in a throw-away directory.
|
||||
It shows how Marlin’s **tags** give you cross-folder “links” that a plain Bash
|
||||
workflow can’t match without resorting to symlinks or scratch scripts.
|
||||
|
||||
Everything uses *only the functionality that exists today* (`init / scan / tag`)
|
||||
plus one `sqlite3` query for discovery.
|
||||
|
||||
---
|
||||
|
||||
## 0 . Prep
|
||||
|
||||
```bash
|
||||
# make a playground so we don't touch real files
|
||||
mkdir -p ~/marlin_demo/{Projects/{Alpha,Beta},Media/Photos,Docs}
|
||||
cd ~/marlin_demo
|
||||
```
|
||||
|
||||
### Create a handful of files
|
||||
|
||||
```bash
|
||||
echo "Alpha draft" > Projects/Alpha/draft.txt
|
||||
echo "Alpha final" > Projects/Alpha/final.txt
|
||||
echo "Beta summary" > Projects/Beta/summary.md
|
||||
echo "Budget spreadsheet" > Docs/budget.ods
|
||||
echo "Scan of receipt" > Docs/receipt.pdf
|
||||
echo "fake JPEG header" > Media/Photos/vacation001.jpg
|
||||
echo "fake JPEG header" > Media/Photos/vacation002.jpg
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 1 . Initialise & scan
|
||||
|
||||
```bash
|
||||
marlin init
|
||||
marlin scan ~/marlin_demo
|
||||
```
|
||||
|
||||
*What happened?*
|
||||
Marlin walked every file under `~/marlin_demo` and upserted rows into `files`.
|
||||
|
||||
---
|
||||
|
||||
## 2 . Tagging – adding cross-folder metadata
|
||||
|
||||
### Tag Alpha project files
|
||||
|
||||
```bash
|
||||
marlin tag "~/marlin_demo/Projects/Alpha/**/*.txt" project-alpha
|
||||
```
|
||||
|
||||
### Tag everything Markdown or ODS as **docs**
|
||||
|
||||
```bash
|
||||
marlin tag "~/marlin_demo/**/*.md" docs
|
||||
marlin tag "~/marlin_demo/**/*.ods" docs
|
||||
```
|
||||
|
||||
### Tag photos
|
||||
|
||||
```bash
|
||||
marlin tag "~/marlin_demo/Media/Photos/**/*.jpg" photos
|
||||
```
|
||||
|
||||
You can layer tags—`vacation001.jpg` now has both `photos` and (later) `trip-2024`
|
||||
if you choose to add that.
|
||||
|
||||
---
|
||||
|
||||
## 3 . Discovering files with plain SQL
|
||||
|
||||
There’s no `marlin search` command *yet*, but the DB is just SQLite:
|
||||
|
||||
```bash
|
||||
sqlite3 ~/.local/share/marlin/index.db <<'SQL'
|
||||
.headers on
|
||||
.mode column
|
||||
|
||||
-- show all files tagged 'docs'
|
||||
SELECT path
|
||||
FROM files f
|
||||
JOIN file_tags ft ON ft.file_id = f.id
|
||||
JOIN tags t ON t.id = ft.tag_id
|
||||
WHERE t.name = 'docs';
|
||||
SQL
|
||||
```
|
||||
|
||||
Expected output:
|
||||
|
||||
```
|
||||
path
|
||||
--------------------------------------------------------------
|
||||
/home/user/marlin_demo/Projects/Beta/summary.md
|
||||
/home/user/marlin_demo/Docs/budget.ods
|
||||
```
|
||||
|
||||
Do the same for `project-alpha`:
|
||||
|
||||
```bash
|
||||
sqlite3 ~/.local/share/marlin/index.db "
|
||||
SELECT path FROM files
|
||||
JOIN file_tags USING(file_id)
|
||||
JOIN tags USING(tag_id)
|
||||
WHERE tags.name = 'project-alpha';
|
||||
"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 4 . Why this beats a pure Bash approach
|
||||
|
||||
| Task | With Bash alone | With Marlin tags |
|
||||
| -------------------------------------------------------------------- | ------------------------------------------------------------------------------- | ----------------------------------------------------------------------------- |
|
||||
| Gather every Alpha file (any extension) scattered across sub-folders | `find ~/Projects -path '*Alpha*'` (works) but blows up if naming scheme changes | One-time glob + `marlin tag ... project-alpha`, then just query by tag. |
|
||||
| Re-classify files later | Mass-rename or new `find`/`grep` pipeline | `marlin tag` new glob or manual ad-hoc files; DB keeps history (future). |
|
||||
| Combine orthogonal facets e.g. “docs AND project-alpha” | Complex `find` piped to `grep -F -f list.txt` or symlink forest | Future `marlin search docs AND project-alpha` (for now SQL query). |
|
||||
| Persist metadata when files move | Must update symlinks / scripts | Scanner sees the move (once watcher lands); tags stay attached by inode/hash. |
|
||||
|
||||
Think of tags as **Git branches for files**—cheap, many-to-many, roam across
|
||||
directories, and live in one place.
|
||||
|
||||
---
|
||||
|
||||
## 5 . Cleaning up
|
||||
|
||||
```bash
|
||||
rm -rf ~/marlin_demo
|
||||
sqlite3 ~/.local/share/marlin/index.db "DELETE FROM files; DELETE FROM tags; DELETE FROM file_tags;"
|
||||
```
|
||||
|
||||
*(or simply delete the DB file to start fresh).*
|
||||
|
||||
---
|
||||
|
||||
### Recap
|
||||
|
||||
1. **Scan** every folder once.
|
||||
2. **Tag** by glob to create semantic “links.”
|
||||
3. **Query** the DB (today) or use future built-in search (soon).
|
||||
|
||||
Even with just these three commands, you get an index that answers questions
|
||||
plain Bash would need an ever-growing tangle of `find`, `grep`, and symlinks to solve.
