Any news here? Fixing that will enable IntelliJ debugging of Elixir, which would be awesome!

[k2m30]

давайте, ребята, соберитесь. очень надо

[sbauer322]

@KronicDeth - I can reproduce the original issue (not the UTF-8 issue) in Ubuntu, if you need help in that regard.

[tiagodocouto]

I can confirm that the exactly same thing is happening on MacOS

[KronicDeth]

I moved Windows problem to #1824. Please only report macOS crashes in this bug if you have badmatch error.

[KronicDeth]

Since I can't reproduce this when doing Elixir Mix ExUnit run configurations on macOS, I took a better look at what is going on and then noticed that @k2m30's command line ends in -extra hello_world.ex. The only way I can see this happening is if you made a Run Configuration with hello_world.ex as the elixir argument, but that does really make sense as a thing to do because how would you call any code in that module? I know it is over a year ago, but what were you trying to do?

If you had a file call hello_world.ex, where you want to call a function you can't just run the file, you need some way to call the function such as using an IEx Mix Run Configuration, so you can type which function to call. I'm going to attribute this to just an invalid use of the run configuration unless you can explain what you were doing to see if I can make it work.

@saialluru's original command line appears to be showing using the debugger on a built release: dev/rel/hello/releases/0.1.0/hello

@sabudaye's command line is about using the IEx Mix Run configuration with phx.server, but on Linux.

All three of these are different usages, so I may once again split this issue further.

With the latest version of IntelliJ and Elixir plugin I am successfully able to start a fat Phoenix app and step through it via the debugger. Kudos for fixing the problem.

[XiXiaPdx]

Coming to Elixir from Java, using Intellij and this plugin is amazing!

I'm having trouble with running the debugger as it crashes. Here is what I see when I try to run the debugger.

Elixir.Debugged':start()' -noshell -user Elixir.IEx.CLI -extra --no-halt -S mix

My Run configuration

Intellij Ultimate 2021.2.2
MacOS Big Sur 11.6
Project SDK for Elixir is 1.12.3
Erlang is 24

My app is this from a Udemy course - https://github.com/StephenGrider/ElixirCode/tree/master/identicon

It runs fine with the Play button, just crashes with the debugger.

I've tried a few things:

1. reduced the project to one file, HelloWorld
2. removed the dependency on egd

Thank you!
