Hey guys!
Two days ago I removed obsolete flycheck-mix-compile from spacemacs Elixir layer. Now it uses lsp (or alchemist) to display errors. If you have the time, please update Spacemacs to most recent develop and check it out

Is this still up tp date? I’ve spent day’s trying to get this to work per these instructions, I have updated layers and additional packaged and installed the release from the zip:
dotspacemacs-configuration-layers
'((elixir :variables slixir-backend 'lsp)
auto-completion
lsp
elixir)
dotspacemacs-additional-packaged
'(use-package lsp-mode
:commands lsp
:ensure t
:diminish lsp-mode
:hook
(elixir-mode . lsp)
(add-to-list 'exec-path “~/elixir-ls/release/language_server.sh”)
)

Hi @Mpanarin,
I’m not sure if you solved your problem. I have one repo that is shared between electronjs and elixir/phoenix projects. The mix.exs is in subfolder of that repo, so elixir-ls has problem locating it. I was trying to apply suggestions from the wiki but it didn’t work for me. So I looked at lsp repo and elixir support there. I found that there are custom variables defined that you can tune. One specific to project location is called lsp-elixir-project-dir. So you have an option just to set it whenever you work with the project or you can automate it.
Looking at lsp repo I found that the function it is using to change elixir-ls options is lsp-register-custom-settings, so I made the following changes:
In init.el (or .emacs) I put the following:
(add-hook 'lsp-after-initialize-hook
(lambda ()
(lsp-register-custom-settings '(("elixirLS.projectDir" lsp-elixir-project-dir)))))
I also created a file called .dir-locals.el in the root folder of my repo with the following content:
((nil . ((lsp-elixir-project-dir . "/<path name of my repo with mix.exs in>"))))
Having these two pieces worked for me. The file local custom variable lsp-elixir-project-dir is set (or default) depending on the repo I’m working with.
If you would like to change some other options It would probably require to add more options to hook function above. Here is a complete list of valiables that lsp-mode sets for elixir when the elixir mode is initialized:
(lsp-register-custom-settings
'(("elixirLS.dialyzerEnabled" lsp-elixir-dialyzer-enabled t)
("elixirLS.dialyzerWarnOpts" lsp-elixir-dialyzer-warn-opts)
("elixirLS.dialyzerFormat" lsp-elixir-dialyzer-format)
("elixirLS.mixEnv" lsp-elixir-mix-env)
("elixirLS.mixTarget" lsp-elixir-mix-target)
("elixirLS.projectDir" lsp-elixir-project-dir)
("elixirLS.fetchDeps" lsp-elixir-fetch-deps t)
("elixirLS.suggestSpecs" lsp-elixir-suggest-specs t)
("elixirLS.signatureAfterComplete" lsp-elixir-signature-after-complete t)
("elixirLS.enableTestLenses" lsp-elixir-enable-test-lenses t)))
You can just copy/paste lines you are interested in tuning then use the custom variables to make changes.
I hope it helps,

I just updated this wiki to update some outdated information and added a section on configuring Doom Emacs
Matsa59
Can’t wait to share with folks : GitHub - Matsa59/web-mode: web template editing mode for emacs · GitHub
Basically I fix <%= f = form ... %> pattern (only support f = ... for now).
Also fix multilines for <%= ... %>.
I would like to have some feedbacks to improve web-mode mode for (l)eex.
For people using doom-emacs, in packages.el use
(package! web-mode
:recipe (:host github :repo "Matsa59/web-mode"))
Disable
webfrominit.eland install usingdoom sync -u
All your configuration should continue to works, I just change elixir language.
Too many times waiting for someone to fix this x)
Spacemacs users : don’t know the configuration but it should works too if you use web-mode.
Edit : for people who wants to wait for official release, you can track this PR : Improve elixir language by Matsa59 · Pull Request #1191 · fxbois/web-mode · GitHub

I has just update Emacs and all relevant packages for Elixir. So that I share some short steps to whom it may help.
- Install packages by config init.el
(require 'package)
(dolist (source '(("org" . "https://orgmode.org/elpa/")
("melpa-stable" . "https://stable.melpa.org/packages/")
("melpa" . "https://melpa.org/packages/")
))
(add-to-list 'package-archives source t))
;; Prefer stable packages.
(setq package-archive-priorities '(("melpa-stable" . 1)
("melpa" . 2)))
(package-initialize)
(when (not package-archive-contents)
(package-refresh-contents))
;;Package list
(defvar anyname/packages
'(helm helm-ag rg paredit use-package erlang elixir-mode flycheck lsp-mode lsp-ui company)
;;Run the defined packages if not install will be install
(dolist (p anyname/packages)
(unless (package-installed-p p)
(package-install p)))
- Install elixir-ls and config as this guide
GitHub - elixir-lsp/elixir-ls: A frontend-independent IDE "smartness" server for Elixir. Implements the "Language Server Protocol" standard and provides debugger support via the "Debug Adapter Protocol" · GitHub
Download the latest release: https://github.com/elixir-lsp/elixir-ls/releases/latest and unzip it into a directory (this is the directory referred to as the "path-to-elixir-ls/release" below)
If using lsp-mode add this configuration:
(use-package lsp-mode
:commands lsp
:ensure t
:diminish lsp-mode
:hook
(elixir-mode . lsp)
:init
(add-to-list 'exec-path "path-to-elixir-ls/release"))
