4. Publish your own package

Ada has a small fpm library, vectors, tagged v0.1.0 and pushed to https://github.com/ada/vectors:

fpm.toml

name = "vectors"
version = "0.1.0"
license = "MIT"
description = "Small fixed-size vector algebra"

src/vectors.f90

module vectors
implicit none
private
public :: dot, norm
contains
pure real function dot(a, b)
real, intent(in) :: a(:), b(:)
dot = sum(a*b)
end function dot
pure real function norm(a)
real, intent(in) :: a(:)
norm = sqrt(dot(a, a))
end function norm
end module vectors

To list it, she clones (or forks) the index next to her project and lets FoBiS write the entry from the working copy:

$ fobis publish --index ~/fortran-index/index.toml --source https://github.com/ada/vectors
Added vectors in ~/fortran-index/index.toml (1 module(s))

$ git diff --no-color --unified=0 index.toml
diff --git a/index.toml b/index.toml
index 6ab8d65..650391d 100644

+source = "https://github.com/ada/vectors"
+description = "Small fixed-size vector algebra"
+license = "MIT"
+provides = ["vectors"]
+

The description and licence come from fpm.toml, the module list from src/. She checks the index:

$ fobis index check index.toml
index.toml: valid index 'szaghi', 171 package(s)

then adds the source to seeds.toml too (so the index can be regenerated) and opens a pull request. Once merged, anyone who registered the index finds vectors with fobis search.

Her later releases need nothing in the index: she tags v0.2.0, and fobis add vectors or fobis fetch --update find it in her repository.

The cookbook has the variations: a CMake project, releases without git, your own index.
