# Usage
Standard usage is to pass a git repository to `cargo generate` or short `cargo gen`. This will prompt you to enter the name of your project.
> ⚠️ NOTE: `cargo gen` requires a [cargo alias configuration](#cargo-gen---alias)
```sh
# full git url
cargo generate --git https://github.com/username-on-github/mytemplate.git
# shorthand for github (org/repo expands to https://github.com/org/repo.git)
# note: if a local directory with that name exists, it is used as a path instead
cargo generate --git username-on-github/mytemplate
# is the same as
cargo generate username-on-github/mytemplate
# prefixed shorthand (works with --git or as positional argument)
cargo generate gh:username-on-github/mytemplate
# is the same as
cargo generate --git gh:username-on-github/mytemplate
```
If you have your templates not GitHub then you can leverage the lazy abbreviation prefixes:
```sh
# for gitlab.com
cargo generate gl:username-on-gitlab/mytemplate # translates to https://gitlab.com/username-on-gitlab/mytemplate.git
# or for bitbucket.org
cargo generate bb:username-on-bitbucket/mytemplate # translates to https://bitbucket.org/username-on-bitbucket/mytemplate.git
# or for github.com
cargo generate gh:username-on-github/mytemplate # translates to https://github.com/username-on-github/mytemplate.git
# or for git.sr.ht
cargo generate sr:username-on-sourcehut/mytemplate # translates to https://git.sr.ht/~username-on-sourcehut/mytemplate (note the tilde)
```
Both will expand to the `https` urls of the repo with the suffix `.git` in the URL.
You can also pass the name of your project to the tool using the `--name` or `-n` flag:
```sh
cargo generate --git https://github.com/username-on-github/mytemplate.git --name myproject
```
## Templates in subfolders
If the repository or path specified for the template contains multiple templates (Any sub-folder that contains a `cargo-generate.toml` file), `cargo-generate` will ask for the specific folder to be used as the template.
Multiple *sub-templates* can also be configured in the `cargo-generate.toml` file like this:
```toml
[template]
sub_templates = ["folder1", "folder2"]
```
Doing so also sets the order when `cargo-generate` asks what to expand, while the first option will be the default.
The specific subfolder in the git repository may be specified on the command line like this:
```sh
cargo generate --git https://github.com/username-on-github/mytemplate.git <relative-template-path>
```
> ⚠️ NOTE: When using the `subfolder` feature, `cargo-generate` will search for the `cargo-generate.toml` file in the subfolder first, traversing back towards the template root in case it is not found.
## Generating into current dir
If the user wants to generate a template straight into the current folder, without creating a subfolder for the contents and without attempting to initialize a `.git` repo or similar, the `--init` flag can be used.
```sh
cargo generate --init --git https://github.com/username-on-github/mytemplate.git
```
> ⚠️ NOTE: `cargo-generate` will not allow any existing files to be overwritten and will fail to generate any files should there be any conflicts.
## Generating using a local template
You can generate a project using a local template via the `--path` flag:
```sh
git clone https://github.com/username-on-github/mytemplate.git $HOME/mytemplate # Clone any template
cargo generate --path $HOME/mytemplate # Use it locally
```
> ⚠️ NOTE: `cargo-generate` will not allow to use the association `--path` and `--git` flags.
## Http(s) proxy
New in version [0.7.0] is automatic proxy usage. So, if http(s)\_PROXY env variables are provided, they
will be used for cloning a http(s) template repository.
