# cargo-locate-project(1)

## NAME

cargo-locate-project — Print a JSON representation of a Cargo.toml file’s location

## SYNOPSIS

`cargo locate-project` [options]

## DESCRIPTION

This command will print a JSON object to stdout with the full path to the manifest. The manifest is found by searching upward for a file named `Cargo.toml` starting from the current working directory.

If the project happens to be a part of a workspace, the manifest of the project, rather than the workspace root, is output. This can be overridden by the `--workspace` flag. The root workspace is found by traversing further upward or by using the field `package.workspace` after locating the manifest of a workspace member.

## OPTIONS

`--workspace`

  Locate the `Cargo.toml` at the root of the workspace, as opposed to the current workspace member.

### Display Options

`--message-format` fmt

  The representation in which to print the project location. Valid values:

  - `json` (default): JSON object with the path under the key “root”.
  - `plain`: Just the path.
`-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`

  Do not print cargo log messages. May also be specified with the `term.quiet` config value.

`--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.

### Manifest Options

`--manifest-path` path

  Path to the `Cargo.toml` file. By default, Cargo searches for the `Cargo.toml` file in the current directory or any parent directory.

### 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.

`--config` KEY=VALUE or PATH

  Overrides a Cargo configuration value. The argument should be in TOML syntax of `KEY=VALUE`, or provided as a path to an extra configuration file. This flag may be specified multiple times. See the command-line overrides section for more information.

`-C` PATH

  Changes the current working directory before executing any specified operations. This affects things like where cargo looks by default for the project manifest (`Cargo.toml`), as well as the directories searched for discovering `.cargo/config.toml`, for example. This option must appear before the command name, for example `cargo -C path/to/my-project build`.

  This option is only available on the nightly channel and requires the `-Z unstable-options` flag to enable (see #10098).

`-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. Display the path to the manifest based on the current directory:

       cargo locate-project
