Ah, interesting. I wonder what in your melpa directory ended up modifying the PATH. Glad you got it working!

Is the main elixir-ls repo actively maintained again? I see it has new commits.
Btw, I just setup my emacs for elixir development. Thanks for this guide! This is all the configuration I needed to get a very functional setup. Maybe someone finds it useful.
(use-package elixir-mode)
(use-package yasnippet)
(use-package lsp-mode
:bind ("C-c h" . lsp-describe-thing-at-point)
:commands lsp
:ensure t
:diminish lsp-mode
:hook
(elixir-mode . lsp)
:init
(add-to-list 'exec-path "D:/repos/elixir-ls/release")
(setq lsp-ui-doc-enable nil))
(use-package company)
(use-package company-lsp
:bind
("M-SPC" . company-complete)
:config
(push 'company-lsp company-backends)
(setq company-idle-delay 0)
(setq company-minimum-prefix-length 1))

Yeah it is currently being maintained. Updated the wiki accordingly. And thanks for sharing your configuration!

I’m also struggling to get syntax highlighting working. The language server highlights errors once, when opening the project for the first time. After saving, errors are not updated. In addition, jumping to definitions doesn’t seem to work properly either. Here’s my relevant setup:
Elixir 1.8.1
Erlang 21
ElixirLS JakeBecker v0.2.25
(use-package flycheck
:hook (after-init-hook . global-flycheck-mode))
(use-package lsp-mode)
(use-package lsp-ui
:config
(define-key lsp-ui-mode-map [remap xref-find-definitions] #'lsp-ui-peek-find-definitions)
(define-key lsp-ui-mode-map [remap xref-find-references] #'lsp-ui-peek-find-references)
(setq lsp-ui-sideline-enable t
lsp-ui-doc-enable t
lsp-ui-doc-delay 1.0
lsp-ui-doc-position 'bottom
lsp-ui-flycheck-enable t
lsp-ui-imenu-enable t
lsp-ui-sideline-ignore-duplicate t))
(use-package company-lsp
:config
(push 'company-lsp company-backends))
(add-to-list 'exec-path (expand-file-name "~/.emacs.d/elixir-lsp/"))
(use-package elixir-mode
:config
(add-hook
'elixir-mode-hook
#'lsp))
I’m using lsp-mode for C++ with no problems, so I doubt it’s the issue. Any ideas? The log shows:

What compilation errors are you receiving? And is syntax highlighting in general not working, or just the highlighting of errors?

Shouldn’t this line:
(add-to-list 'exec-path (expand-file-name "~/.emacs.d/elixir-lsp/"))
contain release at the end, like this:
(add-to-list 'exec-path (expand-file-name "~/.emacs.d/elixir-lsp/release/"))

Thanks for the replies!
Sorry, I should have clarified. I’ve attached a screenshot of an example program and the error, after which elixir-lsp becomes unresponsive.
Example File (In mix project):
defmodule LspTest do
foo
bar
baz
@moduledoc """
Documentation for LspTest.
"""
@doc """
Hello world.
## Examples
iex> LspTest.hello()
:world
"""
def hello do
foobar
:world
end
end

I downloaded the pre-built server at https://github.com/JakeBecker/elixir-ls/releases/download/v0.2.25/elixir-ls.zip , which doesn’t use the release folder. I’ve also tried building it myself, and have changed the folder accordingly with no avail.

Something I had to do when I was getting random lsp errors from elixir-ls was to upgrade the dependencies in the project mix deps.upgrade --all to update the dialyzer dependency to rc6. It’s worth a shot.
Also my coworker had issues when his erlang version updated and he had to rebuild elixir-ls to get it to go away.
Sorry no direct answer but some things to try

Hi guys.
I have followed the wiki to install LSP, and it’s working pretty well. My problem though, it’s that I cannot use “go to definition”, and I don’t know why. When I try to use it, my Spacemacs says something like
No workspace could handle textDocument/definition
Any ideas? Probably I’m doing something wrong.
Thanks for your help.

Hmm, that error makes it sound like the LS has crashed or isn’t configured. Does your *elixir-ls* or *lsp-log* buffers have any errors?
