I am not seeing red wiggly squiggles under syntax errors in .exs
files (or Dialyzer warnings either). Syntax highlighting intermittently works on .ex
files.
Here is a minimal case to reproduce the issue.
% elixir --version
Erlang/OTP 24 [erts-12.0.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]
Elixir 1.12.1 (compiled with Erlang/OTP 24)
%
% # Check VSCode is not running
% ps aux | grep vscode

% # Remove all VSCode config
% # !!!!!!!!!!!!!! Make a copy first!
% rm -r ~/.config/Code/; rm -r ~/.vscode/extensions

# Create "foo" test project
% mix new foo
* creating README.md
* creating .formatter.exs
* creating .gitignore
* creating mix.exs
* creating lib
* creating lib/foo.ex
* creating test
* creating test/test_helper.exs
* creating test/foo_test.exs
Your Mix project was created successfully.
You can use "mix" to compile it, test it, and more:
cd foo
mix test
Run "mix help" for more commands.
% # Create syntax error with an additional unmatched "end"
% echo "end" >> foo/test/foo_test.exs
% # Start VSCode in the "foo" project directory
% code foo
Open test/foo_test.exs in VSCode, see the message:
The Marketplace has extensions that can help with '.exs' files
Install ElixirLS
Navigate back to test/foo_test.exs.
Observe that there is no syntax hightlighting on the additional keyword “end” inserted earlier.
Perhaps this issue is related to the following that I see regularly but can’t reliably reproduce:
[Info - 2:51:55 pm] [ElixirLS Dialyzer] Writing manifest...
[Info - 2:51:55 pm] [ElixirLS Dialyzer] Done writing manifest in 1558 milliseconds.
[Warn - 2:52:55 pm] Received $/cancelRequest for unknown request id: 52
What am I missing to have syntax highlighting in .exs
files?
