# Fortran Package Manager

This is the repository of the Fortran Package Manager (fpm).
If you are looking for _fpm--packaging made simple_ instead, see
[jordansissel/fpm](https://github.com/jordansissel/fpm).

Fortran Package Manager is an early prototype.
You can use it to build and package your Fortran projects, as
well as to include supported Fortran dependency projects.
As a prototype, changes to fpm's behavior and inputs may occur as development continues.
Please follow the [issues](https://github.com/fortran-lang/fpm/issues)
to contribute and/or stay up to date with the development.
As the prototype matures and we enter production, we will do our best to stay backwards compatible.

## Getting started

### Install Haskell

To install **Haskell Stack**, follow these [instructions](https://docs.haskellstack.org/en/stable/install_and_upgrade/),
users without superuser (admin) permissions should follow the [manual installation](https://docs.haskellstack.org/en/stable/install_and_upgrade/#manual-download_2) procedure.

### Download this repository

```bash
git clone https://github.com/fortran-lang/fpm
cd fpm
```

### Build and Test fpm

Build fpm using:
```bash
stack build
```
To test:
```bash
stack test
```
To install:
```bash
stack install
```

On Linux, the above command installs `fpm` to `${HOME}/.local/bin`.

### Creating a new project

Creating a new fpm project is as simple as running the command `fpm new project_name`.
This will create a new folder in your current directory with the following contents
and initialized as a git repository.

* `fpm.toml` with your project's name and some default standard meta-data
* `README.md` with your project's name
* `.gitgnore`
* `src/project_name.f90` with a simple hello world subroutine
* `app/main.f90` (if `--with-executable` flag used) a program that calls the subroutine
* `test/main.f90` (if `--with-test` flag used) an empty test program

### Building your Fortran project with fpm

fpm understands the basic commands:

* `fpm build` - build your library, executables and tests
* `fpm run` - run executables
* `fpm test`- run tests

The command `fpm run` can optionally accept the name of the specific executable
to run, as can `fpm test`; like `fpm run specifc_executable`. Command line
arguments can also be passed to the executable(s) or test(s) with the option
`--args "some arguments"`.

See additional instructions in the [Packaging guide](PACKAGING.md).
