Configuration settings for neovim

[todorovski-m]

Hi,
I was trying to configure fortls in neovim with partial success. I have installed conda install -c conda-forge fortls and in my init.lua I have this single line require'lspconfig'.fortls.setup{}
I was performing test on a small program. In the first case fortls immediately spotted the error in the code

But the following error was ignored

However the VS Code extension works well and detected the error

Could you please help me to solve the problem in neovim? What I'm missing there?

So what you see in VS Code is a combination of fortls diagnostics + linter diagnostics.
The diagnostics provided by fortls are as follows, Everything else is from gfortran:

• Diagnostics
  • Multiple definitions with the same variable name
  • Variable definition masks definition from parent scope
  • Missing subroutine/function arguments
  • Unknown user-defined type used in TYPE/CLASS definition
    (only if visible in project)
  • Unclosed blocks/scopes
  • Invalid scope nesting
  • Unknown modules in USE statement
  • Unimplemented deferred type-bound procedures
  • Use of non-imported variables/objects in interface blocks
  • Statement placement errors (CONTAINS, IMPLICIT, IMPORT)

Thank you very much for your detailed answer. It helped me a lot. It seems that ALE (Asynchronous Lint Engine) in combination with neovim LSP does the same as your VS Code extension. Now I get diagnostics from both fortls and gfortran.

Glad I was able to help and nice to see that neovim has a linter for Fortran too!
