amble
is a cli application for generating rust projects
with batteries included. By using a workspace and
sub-crates, amble
scales to any number of crates.
You can think of amble
as an extension of cargo init
.
Cargo provides convenience methods
for generating new project structures, the two primary
types being a library or a binary project. Below is an
example of the directory structure generated by
cargo init --lib
. (A binary project would only differ
in having a main.rs
file instead of lib.rs
).
project
├─ Cargo.toml
└─ src
└─ lib.rs
amble
provides a more extensive cli command for generating
project directory structures with workspaces.
Library sub-crates are nested inside the cannonical
crates/
directory, while binary crates are nested inside
the bin/
directory. A top-level Cargo.toml
file defines
a workspace including the binaries and libraries as well as
shared package metadata and dependencies, minimizing
inconsistencies across the sub-crates. amble
also exposes
the --lib
and --bin
flags which fallback to cargo init
and create the default cargo init
file structure with all
amble
batteries included and available through cli flags.
Below is an example waterfall directory structure output
for when amble
is run with the argument project
as
the project name.
project
├─ Cargo.toml
├─ bin
│ └─ example
│ ├─ Cargo.toml
│ └─ src
│ └─ main.rs
└─ crates
└─ common
├─ Cargo.toml
└─ src
└─ lib.rs
As detailed in Usage below, this output is generated by running amble project --dry-run
.
Install amble
using cargo.
cargo install amble
Alternatively, amble
can be built from source.
git clone [email protected]:refcell/amble.git && cd amble
cargo build --release
To run amble
, it is recommended to first run it in dry mode which will print
a waterfall directory structure for the files that would be created when run
without dry mode. Simply run amble <project_name> --dry-run
, where <project_name>
is the name of the project/directory you want to create.
By default, amble
uses the current directory for the project name, so it
is perfectly acceptable to run amble --dry-run
, which will just use .
as the project path. Note, amble will exit if it finds cargo artifacts
in the directory you chose to execute in.
To run amble
out of dry mode, just run amble
!
A pre-defined github action ci workflow can be automatically generated by
passing in the --with-ci
flag to amble
. This would generate a directory
structure as follows (amble --dry-run --with-ci
).
.
├─ Cargo.toml
├─ bin
│ └─ example
│ ├─ Cargo.toml
│ └─ src
│ └─ main.rs
├─ crates
│ └─ common
│ ├─ Cargo.toml
│ └─ src
│ └─ lib.rs
└─ .github
└─ workflows
└─ ci.yml
Amble also provides fallthrough methods for generating
cargo init
library and binary projects with batteries such as
a templated readme, github action ci workflows, and licensing.
The flags to pass through to cargo init
operations are injective,
meaning amble --bin
will pass through to cargo init --bin
and
amble --lib
will pass through to cargo init --lib
. As usual,
any other valid amble flag can be provided along with the --lib
and --bin
flags.
Below is an inexhaustive list of the main cli flags.
These are subject to change and new ones can be added.
To view a more up-to-date list, run the amble --help
command locally.
First class, scalable rust project generator with batteries included.
Usage: amble [OPTIONS] [PROJECT_DIR]
Arguments:
[PROJECT_DIR] The path to the project directory. By default, the current working directory is used. If any rust artifacts are detected in the specified or unspecified directory, an error will be thrown [default: .]
Options:
-v, --v... Verbosity level (0-4)
--dry-run Dry run mode. If this flag is provided, the cli will not execute commands, printing the directories and files that would be created instead
--overwrite Overwrite existing files. If this flag is provided, the cli will overwrite existing files
--bare Bare mode. Only for `--bin` and `--lib` flags. If specified, generated files will be the basic `cargo init` files
-n, --name <NAME> The project name. This will be used for the binary application name [default: example]
-w, --with-ci Add github actions ci workflow
-c, --ci-yml <CI_YML> Copy the specified ci workflow file to the project's `.github/workflows/` directory
-a, --authors <AUTHORS> Override the project authors
-b, --bin Builds a cargo binary project
-l, --lib Builds a cargo library project
--without-readme Prevents a readme from being generated
--full Full generates a full project structure including license, ci, gitignore, etc
--etc Adds an `etc/` directory to the project. This _Et Cetera_ directory is used for storing miscellaneous files
--assets Adds template assets to the `etc/` directory of the generate project. Will be run automatically if the `--full` flag is provided
--license Adds an MIT License to the project. The MIT License type can be overridden with the `--with-license` flag
--gitignore Adds a Gitignore file to the project
-d, --description <DESCRIPTION> Specifies the description of the project in the top-level `Cargo.toml` workspace
--dependencies <DEPENDENCIES> Adds these dependencies to the top-level `Cargo.toml` workspace alongside the default dependencies
--list Lists the default dependencies
--with-license <WITH_LICENSE> License Override. This will override the default MIT License. The license type must be a valid SPDX license identifier
-h, --help Print help
-V, --version Print version
You can generate this output by running amble --help
