Quick Start

Casita requires Rust 1.94.1 or newer. From a source checkout, install the CLI:

$ git clone https://github.com/cachix/casita.git
$ cd casita
$ cargo install --path crates/casita

These commands use the repository checkout as the example project. Run them from its top-level directory.

Store a directory

Create a local repository at ./cache, then import Casita’s source directory under the name projects/demo:

$ casita --repository ./cache init
$ casita --repository ./cache import ./crates/casita/src --root projects/demo
$ casita --repository ./cache root ls

The import prints a directory object key, such as casita.directory.v1:.... The root keeps that directory and its contents available across restarts.

Inspect and restore it

Use the key printed by import in place of casita.directory.v1:...:

$ casita --repository ./cache tree list casita.directory.v1:...
$ casita --repository ./cache checkout casita.directory.v1:... ./restored

Checkout requires an absent or empty destination. By default, it also creates an auto/checkout/... root that retains the restored graph. Use --no-root if you do not need that extra root.

Copy it to another repository

$ casita sync --from ./cache --to ./mirror --root projects/demo
$ casita --repository ./mirror root ls

The destination verifies the graph before setting its root. For SSH sources, path selection, and retry behavior, see Synchronization.

Check and collect

$ casita --repository ./cache fsck --audit-only
$ casita --repository ./cache gc --dry-run

fsck --audit-only checks integrity without repairing physical data. The GC dry run shows what collection would remove. To collect, run gc without --dry-run. Named roots and active operations protect their reachable data.

Without --repository, casita init attaches a project directory to Casita’s per-user repository using a .casita workspace marker. See the CLI reference if you prefer that workflow.
