DEPRECATED

Due to fortls support in emacs-lsp this package is deprecated and will not work as expected.

lsp-fortran

Fortran-support for the lsp-mode using the Fortran-Language-Server.

Note that this and the language server itself are still under development

Installation

Language-Server

First install Fortran-Language-Server via

sudo pip install fortran-language-server

Emacs

(add-to-list 'load-path "<path to lsp-fortran>")
(require 'lsp-fortran)

;; Or with use-package, refer to https://github.com/MagB93/lsp-fortran/issues/1#issuecomment-439398514
(use-package lsp-mode
  :init
  :hook
  (f90-mode . lsp-fortran-enable)
  :config
  (use-package lsp-ui
    :ensure f
    :after flycheck))
(use-package lsp-fortran
  :after lsp-mode)

Configuration

At the moment the following default values are passed to the language server as option

--symbol_skip_mem
--incremental_sync
--autocomplete_no_prefix

To change the arguments you have to modify the value of lsp-fortran-flags. For additional options see Fortran-Language-Server or fortls --help.

All issues/ideas/elisp-improvements are welcome! Dont' hesitate to open an issue regarding problems or create a PR.

Using eglot

It is also possible to use eglot instead of lsp-mode. Here is the minimal configuration for eglot:

(use-package eglot
  :ensure t
  :config
  (add-to-list 'eglot-server-programs '(f90-mode . ("fortls")))
)

Now you just have to call M-x eglot to activate eglot-mode.
