Using Homebrew (macOS)
brew install tmattio/tap/spin
opam install spin
Using a script
curl -fsSL https://github.com/tmattio/spin/raw/main/script/install.sh | bash
You can generate a new project using a template with
spin new. For instance:
spin new bin my_app
Will create a new binary application in the directory
Anyone can create new Spin templates, but we provide official templates for a lot of use cases.
The official Spin templates templates are the following:
- bin - Native project containing a binary.
- cli - Command Line Interface releasable on Opam.
- lib - Library releasable on Opam.
- ppx - PPX library.
- c-bindings - Bindings to a C library.
- js - Js application with Js_of_ocaml.
If you'd like to add an official template, don't hesitate to open a PR!
Other OCaml templates
You can find community Spin templates for various projects here: https://github.com/ocaml-templates
Here are some non-official Spin templates that you can use:
Other non-OCaml templates
Although the focus of Spin is to offer a great project generator for the OCaml ecosystem, it can also be used to generate non-OCaml templates. Here are a few examples:
- spin-python-cli - Spin template for Python CLIs
For a detailed documentation of Spin's CLI, run
spin --help, or refer to the CLI documentation.
spin new TEMPLATE [PATH] [--default] [--ignore-config]
Create a new ReasonML/Ocaml project from a template.
PATH defaults to the current working directory.
--default is passed, the user will not be prompted for configurations that have a default value.
--ignore-config is passed, the configuration file will be ignored and the user will be prompted for all the configurations.
List the official Spin templates.
Prompt the user for values that can be saved in the configuration file.
If a value is present in the configuration file, it will not be prompted when generating a new project.
See our development board for a list of selected features and issues.
Here are some of the improvements we'll be working on as well in for next releases:
- Support windows
- Support CLI options/args for configurations
- Generators for
lib/bin/testfor all templates
We'd love your help improving Spin!
