fortran.nvim

A lua plugin for making it easy to work with Fortran and it's ecosystem of community maintained tools such as

• fortls (Fortran Language Server)
• fpm (Fortran Package Manager)
• fprettify (Fortran Code Formatter)
• fypp (Fortran Preprocessor)

Features

• Sets up fortls for you without any further configuration (customizable as well)
• Integrates with fpm and provides a number of User Commands such as FpmRun, FpmBuild to run from within neovim instance
• Integrates with fprettify and provides a command FpmFormat to format the whole document according to your options provided
• optionally also sets up an autocmd to format the document on save
• Sets the filetype of fypp files as appropriately, enabling the use of syntax highlighting and language server on such files.

Requirements

• You need to install fortls, fprettify, fpm from your respective package manager.
• load this before the plugin https://github.com/neovim/nvim-lspconfig

Installation

lazy.nvim

return {
  "wassup05/fortran.nvim",
  lazy = true,
  -- load the plugin when `ft` is fortran
  ft = { "fortran" },
  opts = {
    -- all your configuration options go here
  }
}

Configuration

-- default config
{
  server_opts = {
    path = "fortls",
    args = {
      "--notify_init",
      "--lowercase_intrinsics",
      "--hover_signature",
      "--hover_language=fortran",
      "--use_signature_help",
      "--enable_code_actions",
    },
    filetypes = { "fortran" },
    settings = {},
  },

  fpm_opts = {
    terminal = true,
    path = "fpm",
      args = {
      -- fpm args go here exactly as you would pass them to fpm
    },
  },

  formatter_opts = {
    path = "fprettify",
    format_on_save = true,
    args = {
      -- fpretiffy args go here exactly as you would pass them to fprettify
      },
  },
}

TODO

• Customization of display of output Fpm subcommands (to a terminal, vertical splits etc)
• Adding more commands
• Handling arguments of given to the commands

There is a lot of scope for improvment, So bug reports and contributions are very much welcome
