cargo, make me a project

cargo-generate is a developer tool to help you get up and running quickly with a new Rust project by leveraging a pre-existing git repository as a template.

Here's an example of using cargo-generate with this template:

Installation

Using cargo with system's OpenSSL

cargo install cargo-generate

See the openssl-sys crate readme on how to obtain the OpenSSL library for your system. Alternatively, use the vendored-openssl flag if you do not want to install OpenSSL.

Using cargo with vendored OpenSSL

cargo install cargo-generate --features vendored-openssl

Manual Install:

1. Download the binary tarball for your platform from our releases page.

2. Unpack the tarball and place the binary cargo-generate in ~/.cargo/bin/

Usage

Standard usage is to pass a --git flag to cargo generate or short cargo gen. This will prompt you to enter the name of your project.

cargo generate --git https://github.com/githubusername/mytemplate.git

You can also pass the name of your project to the tool using the --name or -n flag:

cargo generate --git https://github.com/githubusername/mytemplate.git --name myproject

Templates

Templates are git repositories whose files contain placeholders. The current supported placeholders are:

• {{authors}}: this will be filled in by a function borrowed from Cargo's source code, that determines your information from Cargo's configuration.
• {{project-name}}: this is supplied by either passing the --name flag to the command or working with the interactive CLI to supply a name.
• {{crate_name}}: the snake_case_version of project-name
• dates: the liquid date filter is enabled for this project. This means you can write something like {{ "now" | date: "%Y-%m-%d %H:%M" }}. For more information, check out the Liquid Documentation on date.

You can also add a .genignore file to your template. The files listed in the .genignore file will be removed from the local machine when cargo-generate is run on the end user's machine. The .genignore file is always ignored, so there is no need to list it in the .genignore file.

Here's a list of currently available templates. If you have a great template that you'd like to feature here, please file an issue or a PR!

Include / Exclude

Templates support a cargo-generate.toml, with a "template" section that allows you to configure the files that will be processed by cargo-generate. The behavior mirrors Cargo's Include / Exclude functionality, which is documented here. If you are using placeholders in a file name, and also wish to use placeholders in the contents of that file, you should setup your globs to match on the pre-rename filename.

[template]
include = ["Cargo.toml"]
# include and exclude are exclusive, if both appear we will use include
exclude = ["*.c"]
