cargo new - The Cargo Book

# cargo-new(1)

## NAME

cargo-new - Create a new Cargo package

## SYNOPSIS

`cargo new` [options] path

## DESCRIPTION

This command will create a new Cargo package in the given directory. This includes a simple template with a `Cargo.toml` manifest, sample source file, and a VCS ignore file. If the directory is not already in a VCS repository, then a new repository is created (see `--vcs` below).

The "authors" field in the manifest is determined from the environment or configuration settings. A name is required and is determined from (first match wins):

- `cargo-new.name` Cargo config value
- `CARGO_NAME` environment variable
- `GIT_AUTHOR_NAME` environment variable
- `GIT_COMMITTER_NAME` environment variable
- `user.name` git configuration value
- `USER` environment variable
- `USERNAME` environment variable
- `NAME` environment variable

The email address is optional and is determined from:

- `cargo-new.email` Cargo config value
- `CARGO_EMAIL` environment variable
- `GIT_AUTHOR_EMAIL` environment variable
- `GIT_COMMITTER_EMAIL` environment variable
- `user.email` git configuration value
- `EMAIL` environment variable

See the reference for more information about configuration files.

See cargo-init(1) for a similar command which will create a new manifest in an existing directory.

## OPTIONS

### New Options

`--bin`
  Create a package with a binary target (`src/main.rs`). This is the default behavior.
`--lib`
  Create a package with a library target (`src/lib.rs`).
`--edition` edition
  Specify the Rust edition to use. Default is 2018. Possible values: 2015, 2018
`--name` name
  Set the package name. Defaults to the directory name.
`--vcs` vcs
  Initialize a new VCS repository for the given version control system (git, hg, pijul, or fossil) or do not initialize any version control at all (none). If not specified, defaults to `git` or the configuration value `cargo-new.vcs`, or `none` if already inside a VCS repository.
`--registry` registry
  This sets the `publish` field in `Cargo.toml` to the given registry name which will restrict publishing only to that registry.

  Registry names are defined in Cargo config files. If not specified, the default registry defined by the `registry.default` config key is used. If the default registry is not set and `--registry` is not used, the `publish` field will not be set which means that publishing will not be restricted.

### Display Options

`-v`
`--verbose`
  Use verbose output. May be specified twice for "very verbose" output which includes extra output such as dependency warnings and build script output. May also be specified with the `term.verbose` config value.
`-q`
`--quiet`
  No output printed to stdout.
`--color` when
  Control when colored output is used. Valid values:
  - `auto` (default): Automatically detect if color support is available on the terminal.
  - `always`: Always display colors.
  - `never`: Never display colors.

  May also be specified with the `term.color` config value.

### Common Options

`+`toolchain
  If Cargo has been installed with rustup, and the first argument to `cargo` begins with `+`, it will be interpreted as a rustup toolchain name (such as `+stable` or `+nightly`). See the rustup documentation for more information about how toolchain overrides work.
`-h`
`--help`
  Prints help information.
`-Z` flag
  Unstable (nightly-only) flags to Cargo. Run `cargo -Z help` for details.

## ENVIRONMENT

See the reference for details on environment variables that Cargo reads.

## EXIT STATUS

- `0`: Cargo succeeded.
- `101`: Cargo failed to complete.

## EXAMPLES

1. Create a binary Cargo package in the given directory:

       cargo new foo
