# obj-cli

> Command-line inspector and operator tools for the `obj` database.

[![crates.io](https://img.shields.io/crates/v/obj-cli.svg)](https://crates.io/crates/obj-cli)

Part of [`obj`](https://github.com/uname-n/obj) — the embedded document
database. A thin, read-only wrapper over the public `obj-db` API for
inspecting and operating `.obj` files from a terminal.

Crate name `obj-cli`; installs the `obj` binary.

---

## Install

```bash
cargo install obj-cli
```

---

## Commands

```bash
obj check  <file>                          # full bidirectional integrity check
obj stat   <file>                          # header info, page counts, per-collection stats
obj dump   <file> --collection <name>      # walk a collection's primary tree, one record per line
obj backup <src> <dest>                    # hot backup; writers continue uninterrupted
```

| Command  | Purpose                                                                 |
|----------|-------------------------------------------------------------------------|
| `check`  | Run the full integrity check and report success / failure.              |
| `stat`   | Print a structured summary: header, page counts, per-collection stats.  |
| `dump`   | Print records from a collection's primary B-tree (no schema decode).    |
| `backup` | Take a hot backup to a new file while writers continue against the source. |

`dump` accepts `--limit <n>` (`0` = unbounded, default `20`) and
`--format header|hex` (`hex` appends the raw payload bytes). The dump is
type-erased — it prints the per-document header and raw payload, not
schema-aware decoded values, since the CLI has no knowledge of
user-defined `Document` types.

Exit codes: `0` success · `1` operation failure · `3` argument error.
