cargo edit

This tool extends Cargo to allow you to add, remove, and upgrade dependencies by modifying your Cargo.toml file from the command line.

Currently available subcommands:

• cargo add
• cargo rm
• cargo upgrade

Contribution

Thanks for your interest - we gratefully welcome contributions.

Questions can be asked in issues, or on Gitter.

To help us help you get pull requests merged quickly and smoothly, open an issue before submitted large changes. Please keep the contents of pull requests and commits short. Commit messages should include the intent of the commit.

cargo-edit has a moderately comprehensive test suite. Contributions that add/improve tests are awesome. Please add tests for every change.

cargo-edit uses rustfmt-nightly for formatting and clippy for linting.

Installation

$ cargo install cargo-edit

(Please check cargo's documentation to learn how cargo install works and how to set up your system so it finds binaries installed by cargo.)

Install a sub-set of the commands with cargo install -f --no-default-features --features "<COMMANDS>", where <COMMANDS> is a space-separated list of commands; i.e. add rm upgrade for the full set.

Available Subcommands

cargo add

Add new dependencies to your Cargo.toml. When no version is specified, cargo add will try to query the latest version's number from crates.io.

Examples

$ # Add a specific version
$ cargo add regex@0.1.41 --dev
$ # Query the latest version from crates.io and adds it as build dependency
$ cargo add gcc --build
$ # Add a non-crates.io crate
$ cargo add local_experiment --path=lib/trial-and-error/
$ # Also
$ cargo add lib/trial-and-error/

Usage

$ cargo add --help
Usage:
    cargo add <crate> [--dev|--build|--optional] [--vers=<ver>|--git=<uri>|--path=<uri>] [options]
    cargo add <crates>... [--dev|--build|--optional] [options]
    cargo add (-h|--help)
    cargo add --version

Specify what crate to add:
    --vers <ver>            Specify the version to grab from the registry (crates.io).
                            You can also specify versions as part of the name, e.g
                            `cargo add bitflags@0.3.2`.
    --git <uri>             Specify a git repository to download the crate from.
    --path <uri>            Specify the path the crate should be loaded from.

Specify where to add the crate:
    -D --dev                Add crate as development dependency.
    -B --build              Add crate as build dependency.
    --optional              Add as an optional dependency (for use in features). This does not work
                            for `dev-dependencies` or `build-dependencies`.
    --target <target>       Add as dependency to the given target platform. This does not work
                            for `dev-dependencies` or `build-dependencies`.

Options:
    --upgrade=<method>      Choose method of semantic version upgrade. Must be one of
                            "none" (exact version), "patch" (`~` modifier), "minor"
                            (`^` modifier, default), or "all" (`>=`).
    --manifest-path=<path>  Path to the manifest to add a dependency to.
    --allow-prerelease      Include prerelease versions when fetching from crates.io (e.g.
                            '0.6.0-alpha'). Defaults to false.
    -h --help               Show this help page.
    -V --version            Show version.

This command allows you to add a dependency to a Cargo.toml manifest file. If <crate> is a github
or gitlab repository URL, or a local path, `cargo add` will try to automatically get the crate name
and set the appropriate `--git` or `--path` value.

Please note that Cargo treats versions like "1.2.3" as "^1.2.3" (and that "^1.2.3" is specified
as ">=1.2.3 and <2.0.0"). By default, `cargo add` will use this format, as it is the one that the
crates.io registry suggests. One goal of `cargo add` is to prevent you from using wildcard
dependencies (version set to "*").

cargo rm

Remove dependencies from your Cargo.toml.

Examples

$ cargo rm regex
$ cargo rm regex --dev
$ cargo rm regex --build

Usage

$ cargo rm --help
Usage:
    cargo rm <crate> [--dev|--build] [options]
    cargo rm (-h|--help)
    cargo rm --version

Options:
    -D --dev                Remove crate as development dependency.
    -B --build              Remove crate as build dependency.
    --manifest-path=<path>  Path to the manifest to remove a dependency from.
    -h --help               Show this help page.
    -V --version            Show version.

Remove a dependency from a Cargo.toml manifest file.

cargo upgrade

Upgrade dependencies in your Cargo.toml to their latest versions.

Examples

# Upgrade all dependencies
$ cargo upgrade
# Upgrade libc and serde
$ cargo upgrade -d libc --dependency serde

Usage

Upgrade all dependencies in a manifest file to the latest version.

Usage:
    cargo upgrade [--all] [--dependency <dep>...] [--manifest-path <path>]
    cargo upgrade (-h | --help)
    cargo upgrade (-V | --version)

Options:
    --all                       Upgrade all packages in the workspace.
    -d --dependency <dep>       Specific dependency to upgrade. If this option is used, only the
                                specified dependencies will be upgraded.
    --manifest-path <path>      Path to the manifest to upgrade.
    --allow-prerelease          Include prerelease versions when fetching from crates.io (e.g.
                                '0.6.0-alpha'). Defaults to false.
    -h --help                   Show this help page.
    -V --version                Show version.

Dev, build, and all target dependencies will also be upgraded. Only dependencies from crates.io are
supported. Git/path dependencies will be ignored.

All packages in the workspace will be upgraded if the `--all` flag is supplied. The `--all` flag may
be supplied in the presence of a virtual manifest.
