[lyfwfm]

Describe the bug
cannot code completion(or find definition) for new function or new macro

To Reproduce
new a macro in test.hrl (eg: -define(new_macro, test).), then test.erl use ?new_macro, it cannot code completion and cannot jump to definition.

Expected behavior
want code completion and definition

Actual behavior
as above

Context

• erlang_ls version (tag/sha): erlang-ls v0.0.39 in vsCode
• Editor used:
• LSP client used:

ps:erlang_ls.config has include like
include_dirs:
-"include"

important: when i reopen vscode, then i can code completion and find definition, but new function or macro cannot. unless i reopen vscode again

appreciate to all of you for help!!!

I can confirm this.

This happens in a rebar3 project with the following config (from erlang ls docs):

apps_dirs:
  - "_build/default/lib/*"
include_dirs:
  - "_build/default/lib/*/include"
  - "include"

The app has a simple structure like this, generate by rebar3 new app example:

.
├── _build
│   └── default
│       └── lib
│           └── example
│               ├── ebin
│               │   ├── example.app
│               │   ├── example_app.beam
│               │   └── example_sup.beam
│               ├── include -> ../../../../include
│               ├── priv -> ../../../../priv
│               └── src -> ../../../../src
├── erlang_ls.config
├── LICENSE
├── README.md
├── rebar.config
├── rebar.lock
└── src
    ├── example_app.erl
    ├── example.app.src
    └── example_sup.erl

For example adding a new exported function to example_sup and then completing in example the new function won't show up in completions.

thanks a lot.
question above is happen on win10, when i work on wsl, completion works fine. so i think it's maybe bugs on win10

Don't close the issue, please reopen.
This is real and happens on Linux too.

My theory is that this is related to the face that rebar3 creates symlinks in _build to src directory which makes erlang_ls confused as there are two modules resolving to different Uris (one in src and one in _build).

Seems like the src document is updated when changes to the file happens, but completion will do a lookup of the module name and find the Uri of the _build file, which has not been re-indexed.

sounds like that...

I think the solution would either be to not index the _build symlink documents or make sure that those documents are also updated when a change is registed on the src document.

yeah, maybe all(exclude deps) should index the src, and deps could index the _build, because deps not changes frequently

You can try this fix.
