Just found out that lexical does not yet support listing symbols in the current file and in the workspace. That’s a deal breaker for the moment. I’ll wait until that feature is announced and will then resume using lexical.

It looks like this guide along with Lexical’s own installation docs should get things up and running!
I followed that guide but cannot get Lexical to work on Sublime. I get permission denied on a popup when Sublime tries to start Lexical. I can start the script from the command line and the script has executable permissions for everyone:
$ ls -al ~/Downloads/lexical/_build/dev/package/lexical/bin
total 32
drwxr-xr-x@ 6 exadra37 staff 192B 3 Jan 16:20 .
drwxr-xr-x@ 7 exadra37 staff 224B 3 Jan 16:25 ..
-rwxr-xr-x@ 1 exadra37 staff 1.9K 3 Jan 16:25 activate_version_manager.sh
-rwxr-xr-x@ 1 exadra37 staff 580B 3 Jan 16:25 boot.exs
-rwxr-xr-x@ 1 exadra37 staff 230B 3 Jan 16:25 debug_shell.sh
-rwxr-xr-x@ 1 exadra37 staff 483B 3 Jan 17:00 start_lexical.sh
My LSP settings:
"clients": {
"elixir-lexical": {
// enable this configuration
"enabled": true,
// the startup command -- what you would type in a terminal
"command": ["/Users/Exadra37/Downloads/lexical/_build/dev/package/lexical/bin", "start_lexical.sh"],
// the selector that selects which type of buffers this language server attaches to
"selector": "source.elixir"
}
}
Am i missing something?

There are a couple scripts that lexical needs to have execute permission, ensure all of them have that permission:
./lexical/bin/activate_version_manager.sh
./lexical/bin/debug_shell.sh
./lexical/bin/start_lexical.sh
./lexical/priv/port_wrapper.sh
Did the error have any more information other than permission denied?

The only thing it says is the lack of permission, as per screenshot:
Output from Sublime console:

All the scripts have executable permissions as per ls -al output I pasted before:

There are more executable files than you’ve listed above, which is why I asked. There’s an important file that’s not in the bin directory, which is ./lexical/priv/port_wrapper.sh. Though It would be odd for the permission denied error on that file to bubble up to the editor.
Honestly, that error isn’t super helpful without telling me what it’s trying to execute. Very annoying, sublime.
If you want more real-time help, please pop in to our discord server.

There’s an important file that’s not in the
bindirectory, which is./lexical/priv/port_wrapper.sh.
The path doesn’t exist on my repo, but I can find the script at other location wiht executable permissions:
➜ lexical git:(main) l apps/remote_control/priv/
total 8
drwxr-xr-x@ 3 exadra37 staff 96B 3 Jan 16:16 .
drwxr-xr-x@ 10 exadra37 staff 320B 8 Jan 16:24 ..
-rwxr-xr-x@ 1 exadra37 staff 470B 3 Jan 16:16 port_wrapper.sh
Honestly, that error isn’t super helpful without telling me what it’s trying to execute. Very annoying, sublime.
I will see if I can find more detailed logs.

Yes, I can see it there, and has executable permissions for everyone:
$ l _build/dev/package/lexical/priv
total 24
drwxr-xr-x@ 5 exadra37 staff 160B 3 Jan 16:20 .
drwxr-xr-x@ 7 exadra37 staff 224B 3 Jan 16:25 ..
-rw-r--r--@ 1 exadra37 staff 6B 3 Jan 16:25 .elixir
-rw-r--r--@ 1 exadra37 staff 6B 3 Jan 16:25 .erlang
-rwxr-xr-x@ 1 exadra37 staff 470B 3 Jan 16:25 port_wrapper.sh
This is indeed weird
