I’m using VSCode, and syntax highlighting doesn’t work with .exs files . Confoundingly, it seems that mix test will only include .exs files . Is it possible to have both syntax highlighting and doctests in a .ex file?

You can enable doctests by adding doctest MyModule to the test module as seen here Syntax highlighting is a completely different thing.

I never had any issues with *.exs back when I used vscode. If in doubt, just select “elixir” from the list of languages for the file. As a mouse user it’s somewhere in the bottom right, IIRC.

I should have said compiler error syntax highlighting, which isn’t supported: [image] VSCode ElixirLS not highlighting .exs files Questions Hi, ElixirLS does not currently support syntax highlighting errors in .exs files: https://github.com/elixir-lsp/elixir-…

And this definitely works in a .ex (not .exs file)? This and my previous experience seemed show it didn’t work with .ex` files.

Yes, that is referring to test files (that end with _test.exs). But these are doctests within a module .ex. Here is another example of how to set it up and use it.

Run doctests inside `.ex` files
