nvim-fortran-snippets

A Neovim plugin providing LuaSnip snippets for Fortran programming. These snippets are designed to help you quickly create boilerplate code for modules, derived types, and more.

---

Features

• Fortran-specific snippets:
  • Snippets to streamline modern Fortran development.
• Integration with LuaSnip:
  • Uses LuaSnip for snippet management.
• Easy installation:
  • Compatible with packer.nvim.

Installation

Prerequisites

• Neovim 0.10+: Required for Lua-based configuration and plugins.
• LuaSnip: This plugin relies on LuaSnip. Ensure it is installed.

Installing with packer.nvim

1. Add the plugin to your packer.nvim configuration:

   require("packer").startup(function(use)
       -- Install LuaSnip (dependency)
       use "L3MON4D3/LuaSnip"
   
       -- Install nvim-fortran-snippets
       use {
           "gustav-jansen/nvim-fortran-snippets",
           config = function()
               require("fortran_snippets").setup()
           end,
       }
   end)
   

2. Run the following command in Neovim to install the plugin:

   :PackerSync

Usage

1. Open a Fortran file (*.f90, *.f95, etc.).
2. Trigger snippets using your LuaSnip keybindings (usually <Tab> or <C-l> for expansion).
3. Example:
   • Type ndt and expand it to insert a derived type skeleton.

Example Snippets

ndt

Expands into:

module module_name
  implicit none
  private

  public :: type_name

  type :: type_name
  contains
    procedure :: cleanup => cleanup
    procedure :: clear => clear
  end type type_name

  interface type_name
    module procedure constructor
  end interface constructor
contains
  function constructor() result(this)
    type(type_name) :: this

    call this%clear()
  end function constructor

  subroutine cleanup(this)
    class(type_name), intent(inout) :: this

    call this%clear()
  end subroutine cleanup

  subroutine clear(this)
    class(type_name), intent(inout) :: this

  end subroutine clear
end module module_name

Adding More Snippets

To extend or customize the snippets:

1. Open the snippets.lua file in the plugin directory (lua/fortran_snippets/snippets.lua).
2. Add new snippet definitions as separate functions.
