## cargo cache
[](https://github.com/matthiaskrgr/cargo-cache/actions)
[](https://crates.io/crates/cargo-cache)
[](https://lib.rs/crates/cargo-cache)
Display information on the cargo cache (`~/.cargo/` or `$CARGO_HOME`). Optional cache pruning.
#### Key Features:
* check the size of the cargo cache and its components (cmd: `cargo cache`)
* do a simple cleanup removing checkouts but keeping original files needed for reconstruction on disk (`--autoclean`)
* clean up everything (cargo will re-download as needed)
* dry-run to see what would be removed (`--dry-run`)
* recompress git repos (`--gc`)
* search cache via regex queries (`cargo cache query "reg.*x"`)
* print crates that take the most space (`--top-cache-items`)
* alternative registries supported
* remove files older or younger than X (`--remove-if-{older,younger}-than`)
* builds and runs on `stable`, `beta` and `nightly` channel
* purge cache entries not used to build a specified crate (`cargo cache clean-unref`)
* print size stats on a local sccache build cache (`cargo cache sc`)
* verify extracted crate sources (`cargo cache verify`)
#### Installation:
```cargo install cargo-cache```
or for the bleeding edge development version:
```cargo install --git https://github.com/matthiaskrgr/cargo-cache cargo-cache```
#### Default output (`cargo cache`):
This only calculates the sizes and does not touch anything:
````
Cargo cache '/home/matthias/.cargo':
Total: 4.22 GB
102 installed binaries: 920.95 MB
Registry: 2.25 GB
Registry index: 227.07 MB
4412 crate archives: 684.29 MB
2411 crate source checkouts: 1.34 GB
Git db: 1.05 GB
113 bare git repos: 993.72 MB
9 git repo checkouts: 55.48 MB
````
To learn more about the subdirectories inside the cargo home and what can be safely deleted, check `--info`.
#### Usage:

USAGE:
cargo cache [OPTIONS] [SUBCOMMAND]
OPTIONS:
-a, --autoclean Removes crate source checkouts and git repo checkouts

-i, --info Print information cache directories, what they are for and what can be safely deleted
-k, --keep-duplicate-crates Remove all but N versions of crate in the source archives directory
-l, --list-dirs List all found directory paths
-n, --dry-run Don't remove anything, just pretend
-o, --remove-if-older-than Removes items older than specified date: YYYY.MM.DD or HH:MM:SS
-r, --remove-dir Remove directories, accepted values: all,git-db,git-repos,
registry-sources,registry-crate-cache,registry-index,registry
-t, --top-cache-items List the top N items taking most space in the cache
-V, --version Print version information
-y, --remove-if-younger-than Removes items younger than the specified date: YYYY.MM.DD or HH:MM:SS
SUBCOMMANDS:
clean-unref remove crates that are not referenced in a Cargo.toml from the cache

#### Do a light cleanup
This removes extracted tarball sources and repository checkouts.
The original source archives and git repos are kept and will be extracted as needed by cargo.
Run `cargo cache --autoclean`:
````

The crate also works if you override the default location of the cargo home via
the $CARGO_HOME env var!
Side note: cargo-cache started as my *learning-by-doing* rust project, if you see something that you find very odd or is in dire need of improvement please let me know and open a ticket!
#### Cleaning the cache on CI
Sometimes it is desired to [cache the $CARGO_HOME in CI](https://doc.rust-lang.org/nightly/cargo/guide/cargo-home.html#caching-the-cargo-home-in-ci).
As noted in the document, this might cache sources twice which adds unnecessary overhead.
To reduce the size of the cache before storing it, you might want to run `cargo cache --autoclean`.
The `ci-autoclean` feature provides a very stripped-down version of the crate that is only capable of running `cargo-cache --autoclean` automatically on launch and should compile within a couple of seconds.
To make use of this, you can add these commands to your ci:
````bash
cargo install (--git git://github.com/matthiaskrgr/cargo-cache OR cargo-cache) --no-default-features --features ci-autoclean cargo-cache
cargo-cache # no further arguments required
````
You can add the `vendored-libgit` feature if you would like to link libgit statically into cargo-cache.
#### FAQ
Q: Is this project related to [sccache](https://github.com/mozilla/sccache)?
A: Not really.
`cargo cache sccache` prints a little summary of the local(!) sccache-cache and shows how many files were last accessed on a given date but
it does not modify sccaches cache. It also does not act as a compiler cache such as (s)ccache.
